Same! It happens to me now when I bought a new Display Port cable. HDMI has worked fine forever, but now that I switched I have the same issue. Fun to see that Linus 10 years ago would be my savior, as I watch the channel daily.
for anyone who is struggling with this problem; it's caused by a static build-up in the monitor. it's easily fixed by disconnecting the monitor from the power source, holding down the power button for 30 seconds (only needs about 5 really), and plugging it back in. it should be back up and running immediately, with no side-effects or persistent problems. hope that's helped! :)
so you guys know, i'm no expert. i found this video because i had the same problem, but i managed to find an article telling me what i told you guys, which fixed it for me (and the guy in the video) so i thought i would share :D
I think the tip is that you should always make sure to turn off the device as one of your tests. Unplugging the video source won't reset the software, disconnecting it from its power source will.
2024 for me half of my screen was black with a red line going down the middle. Had a tuff time but got it resolved. Reset the driver for my graphics card and updated it. Thank you so much hop I helped somebody!
Linus, I don’t know if you’ll ever read this but THANK YOU SO MUCH for this video! A few days ago I had this same problem with a brand new monitor (which the whole screen was black). I was on the verge of requesting an exchange and I looked up this video and it worked! My monitor has come back to me! You are just too awesome Linus! ❤️❤️ 💋
Been experiencing this lately. Here's my solution: No need to unplug or switch off anything. The issue appears to be caused by drivers (FYI I'm using an RTX 2070 Super). If you're using Windows 10, press "Shift + Ctrl + Win key + B" - this restarts/resets the graphics drivers. Once you've done this, the issue should go away. Unfortunately I haven't found a permanent fix to this, but the above steps work. I seem to get this issue when waking up my screen after sleep/screensaver.
I literally just had this exact same issue, was worried either the monitor or video card had died on me, but thanks to your vid after a power reset the monitor is fine again, wierd problem but you saved me a ton of troubleshooting! *high five*
There is a small car on the back of the screen connected by two ribbons to the buffers card at the top of the screen (each one deals with one half of the screen). What causes this issues can be that card that is faulty or overheating, the ribbons (flat cables) can be dirty or getting damaged. What can happen too is the frame that is putting some extra pressure on those ribbons or one or more of the ribbons that connect the buffer boards to the screen. If you try to investigate by yourself by opening your monitor/tv please be careful not to damage those ribbons as they can be really sensitive in some models, and since they get harder with the heat they can be easy to break.
Just had this happen on a laptop screen. Still trying to figure it out. If I put pressure on the bottom bezel of the screen it actually starts working. Was happy to see a younger Linus had the same issue though lol.
thank you so much linus you just saved my life almost literally, i was on the verge of losing it here and thank god you had this vid up and it solved my problem. funny thing is i have the exact same monitor, and i even have 1 of my 3 that has half the monitor get green pixelation on it that seems like a similar problem but once the monitor warms up for a couple hours its goes away oddly enough.
Had the same issue today - woke up in the morning and the monitor is showing only half. The advice from this video fixed the issue. Really weird this all is.
Latest NVIDIA Driver 417.71 is the culprit, it had enabled G-Sync by default and my monitor is FreeSync turning this off completely resolved this issue for me.
This is exactly what happened to me. I tried turned off the monitor, the PC, unplugging it from the video card... nothing. I saw your video and figured "Unplugging it? That's just crazy enough to work" ... and it did! Thx.
@@JaimexoPlays I actually fixed it- I had accidentally set the monitor to fix display at half the way possible (sorry i am not very good with the technical words) but i just reset all monitor settings from monitor menu and it worked.
2020, just happened to me too. Windows 10 / 34 inch LG Monitor 34UM95. I ran a support team for thousands of PC users at one time and did not practice what I normally preach. "Is it plugged in?" "Have you Restarted it?" I CANNOT BELIEVE 10 MINUTES UNPLUGGED DID THE TRICK I feel like such a nooblet. For what it is worth, thanks for stating the obvious. :)
Thank God for your video. Cause this just happened to me. I figured out my problem. The latest graphics card drivers caused this malfunction on my monitor. I installed and older version and everything is working normal again. I hope this helps some of you if you are having this problem.
Story: I had tried everything. Reading the comments it seems like this worked for everyone, but by this time I had lost faith. Tried this fix and while waiting for 10 minutes I knew I was just going to turn on my computer to see the screen flickering right down the middle again. I decided that I was going to leave a comment indicating that this hadn't worked for me (as I wanted to show that sometimes the problem may lie elsewhere), but that I appreciated the video. ..... To my surprise.....it worked. Thanks! I thought this monitor was bound for the recycle bin. You're the best.
Guys I've had this several times now and you just have to cut power to your display. For desktop users this means pulling the plug for 10-15secs min and then turn it back on, like the video said. However if you want to do this on laptop, you just have to shut it completely down (no sleep or hibernate) and then unplug your adapter and remove the battery for the same 10-15 seconds.
Kudos my man. Same thing happened to me today. I was away rage calling Nvidia / ASUS as I thought it was my GFX card. But a power recycle of the monitor resolved the issue
Strange, my eight-year-old CRT monitor (bought from the wild wilderness that is eBay around three months ago - and at under £1, to boot) - as a long-time office unit - has seen over eight hours of use a day, and still works like an absolute dream. And, at 1600*1200, it has a pretty decent screen resolution, too... It's incredible, then, how older monitor technology still reigns supreme over newer vision solutions. How odd.
hej saw this video a year ago and i got the same monitor so i start my computer up and half of my screen was gone like in your video i directly searched this video again to fix my problem and it worked for me :) thx for sharing this grtz
2020 Feb . Right half is three vertical shade sections. 1 part is fine black/white lines, middle part solid white, right section is solid black which is slightly wider than the other sections. Went that way after banging on it to stop it from a flashing spasm. Old Dell monitor. Thinking the flashing is bad capacitors. Unknown now the right side blackout. Wonder if it is repairable.
Feb 2020 and it just happened to me. Rebooting didn't help, switching off the monitor (but keeping it plugged) did nothing either. Only after unplugging and waiting for about a minute (the extend of my patience) did it resolve itself. Thanks for making these videos :-).
Appreciate it man, this chick at my jobs computer just did this at 8 in the morning and of course they call me to fix it...same monitor and all, worked like a charm, props
Bud Charles you could try pulling the battery after a hard shut down and giving it time to dissipate any charges. that should be the same as unplugging a monitor.
how come this happens to me a lot? I always reset it and that fixes it temporarily. but after I shut it down and use it again, the half black screen pops up again and I have to restart it, AGAIN. what causes the problem in the first place?
Having a similar issue now with a second-hand drawing tablet monitor I bought a while back because I wanted a portable of the same brand as my 27-inch stationary one. I've used it a few times, but today I plugged it in for the first time in about 4 months and the right half of the screen is a big white square. Like with this video, the other half of the screen clearly exists beneath the square. This thing doesn't actually have an external power source beyond whatever usb port it plugs into, so I may be out of luck. I'm going to disconnect for ten minutes and see if that helps, and then after that, since this thing has been in a carry bag for 4 months, I'm going to plug it in and let it warm up while leaving it unacknowledged in my display settings and see if that works. Thanks for the video!
Probably open up the laptop and disconnect the ribbon cable that connects the screen. There may be an additional cable too. It may not work on it though due to it being made differently. If you're going through the effort of detaching it then you might as well just get a new screen.
The screen may have been "twisted". It happened to my laptop screen. I used to pick it up from one corner of screen while its open and "bent" it. To fix it, I tap the screen on that side and it worked. But the problem didnt go away permamantly.
Incredible.... I've had this problem for about a month now and it never occurred to me to physically touch or bend the screen. You just fixed my problem! Thanks!
@tenkirulez - The section is called the "Trouble Shooting" section. :D I looked up the half screen problem in my DELL monitors manual and it said, unplug the power supply. I looked up the problem in my old monitors manual, and it too said, unplug the monitor's power. So I am just saying, given a few of his "hum, I didn't need to do that" videos, that he should read the manuals that come with products before doing a review on them. :) Despite opposing opinions, manuals do help.
Thank you for posting this! I have an HP 1940 monitor but had the same thing happen. I came back into my office and the screen was suddenly like this. Did all the same trouble shooting short of unplugging everything at once except when I gave up and switched to an old smaller monitor. I just now plugged it back in and presto! It would be nice to know why it happened but I'm glad to have my big monitor back.
Just happened to me also. Did all of the above test but luckily came across this video in my first search, on the good half of my screen; fix the problem. I would like to know what caused this as I had a simular problem but he whole screen was black. Turning it off in a well-timed fit of frustration and coming back to it after a glass of wine, fixed the problem but not untill I had bought a new more expensive displey cable. As far as I can tell the symptom is not repeatable.
this was the first thing that showed up when searching on google. I can see i use the exact same monitor as you, and un- and replugging all the things, like you said, seems to have solved the problem. TL;DR: thanks
such a coincidence. this just happened to me also and i realized that it is the exact same monitor AcerGD235HZ. Unplugging and repluggin power cord fixed it. Thanks Linus.
2021, gaming desktop, R9 390X card, I moved the graphics card to a different pcie slot, used different video output plugs on gpu, installed the latest graphics drivers, rebooted repeatedly, changed display resolutions, figured I was out 1000 bucks to attempt to replace with a comparable card, saw this, unplugged my tv, yeah... thanks Linus!
@ShaTR2 Yeah you're probably right. Think about it, this is a 120 Hz monitor. Probably has a display setting to show the difference between 60 Hz and 120 Hz display. Unpluging the power cable and then repluging it might reset that setting.
My screen did not reset itself. 4 hours and 2 techs later I found the problem by accident. The installation of a new cable had enabled the PBP in the monitor menu. Find it and turn it off. You’ll know when you get there because it will show the split screen.
I had a similar problem. Whenever i tried to auto configure, it would not use about 50px on the right of the screen. I could use what was visible, but the picture was squished because of these pixels left out. After watching your tip video, i tried unplugging it from power and plugging it in. Nope. I then tried unplugging it from my video card and re-plugging it. This ended up making about 25 pixels on the left now not used. I hit auto config again a few times and it worked itself out. Woot! :D
Clearly, the problem is in the driver chip of the monitor if it does it with the PC not connected. Apparently the boot routine for the monitor is not stable (Could there have been a very small spike in power on monitor start?) or is there a coding error in the monitor boot rom? If it shows up again, or may not clear on one restart, try it again. Perhaps a driver update accidentally has changed the start up sequence or tries to talk to the monitor during start up and programs it to do this, or fails to set a flag in the display address routine? Re-booting, start-up over again, clear any existing rom setttings, Brilliant idea. Thanks for the tip, just happened to one monitor in this house. Will advise if it works. Party on Duides, be good to each other. Before I could post, feedback is Success! It worked.
most likely when you restarted the computer, a display driver was loaded to the memory that never was in the first place. that is the phenomena we are talking of. with half screen check any driver problem.
Linus Tech Tips, I recently purchased a laptop that has Windows 95 as its operating system. The seller of the computer had pictures of the laptop with a perfect looking screen. When my computer arrived, and I booted it up, my screen was regular on the left side and on the right side a big blob grey, creating the half-screen effect. I was so upset. I kept calm though and tried to find a way out of the dilemma. I pushed the screen slightly back (as you can do with laptops) and the grey faded completely. I had the full screen back. I then slowly brought the screen forward and closed the laptop. When I re-opened it by a little crack to take a peek in the hopes that I could by-pass the grey blob for good, It re-appeared. So I once again moved the screen back just a little, and the full screen was restored. I used the computer for hours and the grey never resurfaced. I shut the computer down. Powered on. The grey was still gone. So, it's just a glitch thing where it has to be back just a little bit.
That happens sometimes with certain Acer monitors, I knew that you had to unplug it before you did it. I've heard several people complain about that issue and say that disconnecting the power fixes it every time. =P
Was the backlighting visible on the blank half, or was the panel completely pitch-black on that side? I can't imagine the LCD panel itself would be split in two, since that would create a visible seam down the middle, but maybe the backlighting is, and for some reason half of it shut down. It could be bad capacitors in the HV power supply, which is a common problem with LCD monitors and TVs.
I've got this same monitor with the exact same black-right-half problem. I've had this monitor since it came out and never had any issues other then sometimes it tries to dim if it thinks I'm idle and a couple times it dimmed very very low. Other than that it's been perfect. Then this happened... I thought the same thing, "WTF IS THIS SHIT? EVEN IN POST/BIOS?" Since I leave my monitor plugged in and never physically turn it off it made sense to unplug to drain capacitors. Now it works! THANKS!
Exact same issue, and oddly enough its the same model monitor. I power cycled and only half of the acer splashscreen logo showed up. Power cycled and now working properly. Gonna miss you linus.
Probably half of the screen is shorted. Normally screens have two or more sections. If one section is shorted that’s one of the symptoms. What Linus did was probably “reset” the problem. That is clearly a hardware issue (monitor).
I own three of the exact same monitors that I used to have set up in panoramic 3d. Each of them has now done this from time to time. I think it must be this particular monitor, as I've also never seen anything like this before or since!
I'm watching this video 11 years later with the exact same ACER display with the exact same problem (It's my second monitor though, primary is much better I promise). I tried everything you tried and it didn't work, just like you. I switched off the power supply for the monitor and was about to swap it out. It's been acting up for a while now, and I actually have a better display that just has a faulty power supply that I have been too lazy to try to fix, but I decided to search if anyone else has had the problem. My surprise when LTT actually covered this, but then half way through the video it doesn't seem like you are going to have a solution. I turn the power supply back on and Voilà at the exact same time your monitor starts working correctly in the video so does mine. WEIRD!
Just had this issue as well, only mine had a solid blue line splitting the screen. One side had my usual settings and the other side displayed the screen with default settings. It seemed more like I activated a something to compare settings instead of a straight up glitch. But this video helped clear it up. I'm not a big fan of 'magic fixes' but it worked out this time. Thanks!
So I think this is to do with the power supply cable being loose rather than needing to leave it off for any amount of time. I had the same issue and after watching your video was about to unplug my power cable and found it loose. Pushed it back in firmly and the black half reappeared as if by magic!!
2020, just happened to me. Thanks from the future.
Same! It happens to me now when I bought a new Display Port cable. HDMI has worked fine forever, but now that I switched I have the same issue. Fun to see that Linus 10 years ago would be my savior, as I watch the channel daily.
Just happened to me and I stumbled upon this video aha
This happened on my laptop
Ditto...
@@brandonroberts-blake4223 what did you do??
for anyone who is struggling with this problem; it's caused by a static build-up in the monitor. it's easily fixed by disconnecting the monitor from the power source, holding down the power button for 30 seconds (only needs about 5 really), and plugging it back in. it should be back up and running immediately, with no side-effects or persistent problems.
hope that's helped! :)

you could try pulling the battery after a hard shut down and giving it time to dissipate any charges. that should be the same as unplugging a monitor.
It could be a loose cable, fucked up screen inverter, or the display itself.

I would like to know what caused this as I had a simular problem but he whole screen was black. Turning it off in a well-timed fit of frustration and coming back to it after a glass of wine, fixed the problem but not untill I had bought a new more expensive displey cable. As far as I can tell the symptom is not repeatable.
HOW ABOUT A FUCKING LAPTOP?
this was the first thing that showed up when searching on google. I can see i use the exact same monitor as you, and un- and replugging all the things, like you said, seems to have solved the problem.
TL;DR: thanks
lol know I have this problem :) and I was thinking that was my graphics card thank you linus
Dragon Ball Legends!!!
i love you man looked for a new screen but i just gave yt a last chance to help me and the best of them all helped me
my laptop windows 10 tow side are like this plz make a video
+fun bun same here
2022, just happened to me and I was confused as hell because I had JUST used the monitor. Thanks, Linus!
Absolute legend! Just fixed the my monitor problem with your video,thank you very much.
such a coincidence. this just happened to me also and i realized that it is the exact same monitor AcerGD235HZ. Unplugging and repluggin power cord fixed it. Thanks Linus.
2021, gaming desktop, R9 390X card, I moved the graphics card to a different pcie slot, used different video output plugs on gpu, installed the latest graphics drivers, rebooted repeatedly, changed display resolutions, figured I was out 1000 bucks to attempt to replace with a comparable card, saw this, unplugged my tv, yeah... thanks Linus!
Same thing happened to me. Exact same monitor. Exact same problem, right half black out. Exact same fix. Thanks for the video!
This video is sacred and pure, it must be protected.
I have two of the exact same one. Both have happened to me and your 10 minute unplug fix did the trick.
7 years later, here is! Thanks for the tips!
@ShaTR2
Yeah you're probably right. Think about it, this is a 120 Hz monitor. Probably has a display setting to show the difference between 60 Hz and 120 Hz display. Unpluging the power cable and then repluging it might reset that setting.
Thanks old Linus video for helping me
My screen did not reset itself. 4 hours and 2 techs later I found the problem by accident. The installation of a new cable had enabled the PBP in the monitor menu. Find it and turn it off. You’ll know when you get there because it will show the split screen.
Truly tech tips moment of all times
I had a similar problem. Whenever i tried to auto configure, it would not use about 50px on the right of the screen. I could use what was visible, but the picture was squished because of these pixels left out.
After watching your tip video, i tried unplugging it from power and plugging it in. Nope.
I then tried unplugging it from my video card and re-plugging it. This ended up making about 25 pixels on the left now not used. I hit auto config again a few times and it worked itself out. Woot! :D
Clearly, the problem is in the driver chip of the monitor if it does it with the PC not connected. Apparently the boot routine for the monitor is not stable (Could there have been a very small spike in power on monitor start?) or is there a coding error in the monitor boot rom? If it shows up again, or may not clear on one restart, try it again. Perhaps a driver update accidentally has changed the start up sequence or tries to talk to the monitor during start up and programs it to do this, or fails to set a flag in the display address routine? Re-booting, start-up over again, clear any existing rom setttings, Brilliant idea. Thanks for the tip, just happened to one monitor in this house. Will advise if it works. Party on Duides, be good to each other. Before I could post, feedback is Success! It worked.
most likely when you restarted the computer, a display driver was loaded to the memory that never was in the first place. that is the phenomena we are talking of. with half screen check any driver problem.
Linus Tech Tips,
I recently purchased a laptop that has Windows 95 as its operating system. The seller of the computer had pictures of the laptop with a perfect looking screen. When my computer arrived, and I booted it up, my screen was regular on the left side and on the right side a big blob grey, creating the half-screen effect. I was so upset. I kept calm though and tried to find a way out of the dilemma.
I pushed the screen slightly back (as you can do with laptops) and the grey faded completely. I had the full screen back. I then slowly brought the screen forward and closed the laptop. When I re-opened it by a little crack to take a peek in the hopes that I could by-pass the grey blob for good, It re-appeared. So I once again moved the screen back just a little, and the full screen was restored. I used the computer for hours and the grey never resurfaced. I shut the computer down. Powered on. The grey was still gone. So, it's just a glitch thing where it has to be back just a little bit.
Just got this recommended after 13 years .
That happens sometimes with certain Acer monitors, I knew that you had to unplug it before you did it. I've heard several people complain about that issue and say that disconnecting the power fixes it every time. =P
just watching this video helped my screens somehow, thanks! 2021 btw.
2024 it happened to me. Thank you so much Linus. You’re getting a like and I don’t usually like anything so
Was the backlighting visible on the blank half, or was the panel completely pitch-black on that side? I can't imagine the LCD panel itself would be split in two, since that would create a visible seam down the middle, but maybe the backlighting is, and for some reason half of it shut down. It could be bad capacitors in the HV power supply, which is a common problem with LCD monitors and TVs.
I've got this same monitor with the exact same black-right-half problem. I've had this monitor since it came out and never had any issues other then sometimes it tries to dim if it thinks I'm idle and a couple times it dimmed very very low. Other than that it's been perfect. Then this happened... I thought the same thing, "WTF IS THIS SHIT? EVEN IN POST/BIOS?"
Since I leave my monitor plugged in and never physically turn it off it made sense to unplug to drain capacitors. Now it works!
THANKS!
2021. Still having the same issue, this fixed it! Thanks!
a quarter of my laptop screen has gone blank any tips thanks
@@BeeTaster break it
@@ti_yos i can do this if you just give me your email and in about a years time you will receive a response to this
Exact same issue, and oddly enough its the same model monitor. I power cycled and only half of the acer splashscreen logo showed up. Power cycled and now working properly. Gonna miss you linus.
Probably half of the screen is shorted. Normally screens have two or more sections. If one section is shorted that’s one of the symptoms. What Linus did was probably “reset” the problem. That is clearly a hardware issue (monitor).
Woah, dealing with this issue now and this video came up as the first option.
Thank you Linus Tech Tips for the solution!
And thank you Tidy Tate for explaining it in the comments
12 years later and it still works
Thanks, can't believe "Turning it off and on again" worked yet again!
I own three of the exact same monitors that I used to have set up in panoramic 3d. Each of them has now done this from time to time. I think it must be this particular monitor, as I've also never seen anything like this before or since!
I'm watching this video 11 years later with the exact same ACER display with the exact same problem (It's my second monitor though, primary is much better I promise).
I tried everything you tried and it didn't work, just like you.
I switched off the power supply for the monitor and was about to swap it out. It's been acting up for a while now, and I actually have a better display that just has a faulty power supply that I have been too lazy to try to fix, but I decided to search if anyone else has had the problem.
My surprise when LTT actually covered this, but then half way through the video it doesn't seem like you are going to have a solution.
I turn the power supply back on and Voilà at the exact same time your monitor starts working correctly in the video so does mine. WEIRD!
Just had this issue as well, only mine had a solid blue line splitting the screen. One side had my usual settings and the other side displayed the screen with default settings. It seemed more like I activated a something to compare settings instead of a straight up glitch. But this video helped clear it up. I'm not a big fan of 'magic fixes' but it worked out this time. Thanks!
Confirming even at the end of 2020 this still works. Though I only had to remove power (not data and everything) for 2-3 minutes myself. Thanks
I have that same or very similar acer monitor, this has happened to me twice. And both times your fix has worked. Thanks.
So I think this is to do with the power supply cable being loose rather than needing to leave it off for any amount of time. I had the same issue and after watching your video was about to unplug my power cable and found it loose. Pushed it back in firmly and the black half reappeared as if by magic!!
2020, just had the same issue. I ended up changing the screen resolution to something else and then change it back. That fixed it somehow.
Tech tips that is so quick, he should create a channel for quick tips and call It Techquickie.
Always a legend. Thank you SO much :D:D My monitor is working now!
How did you do ?
And what you really should do to fix that is check the ribbon cable connection from T-con board to your screen boards.
