Large TVs vs. Monitors for Computers
HTML-код
- Опубликовано: 2 июл 2024
- For the last few years I have been using both large 4K TVs and Computer Monitors for hardware and software development at home and at work. I go over what I found the most significant differences between the two which may be of use if you are considering using TV as a computer monitor. The 43" monitor I use is the LG 43UN700-B. The similarly sized TV is the RCA RTRU4328-CA. I also show a couple of LG 2k 43LX570H-UA hospitably (hotel) TVs that I use over my lab bench.

Please let me know if the audio volume is better in this video than the previous ones! Based on some of your comments, I have increase the volume and I think its more in line with the volume of other things on youtube. I'm travelling right now and the speakers on my laptop are not the greatest so I cant tell how well (or poorly!) it sounds. Thanks!
Audio was excellent for me ... thanks
@@chevy5Gen Thanks for letting me know! Maybe I finally have it right!
Yes, quite good audio. I listen with headphones.
@@retrozmachine1189 Thanks for letting me know - I'm sure headphones are almost a gold standard for listening for volume consistency!
Your audio was excellent on my Alesis monitor speakers!
I have a degree in industrial instumentation and another one in english teaching, so I'm going to enjoy your channel. For me, you have a perfect combination of a nice content and an excellent audio to listen to your pronunciation.
Thanks you so much - just replied to your comment on the eclipse video!
The audio level in this video is much more consistent with other YT offerings, which is an improvement in my opinion. Thanks for the effort.
Thanks for letting me know - really appreciate it!
I have a 32 inch TV and it is WONDERFUL!
I can believe it! By the way - I saw some of your videos where you make triodes and other tubes ages ago - amazing!
I have been using different TVs as monitors for years and the most important thing is the input lag you will get. Sometimes there is a "gaming" mode that makes it better- but some TVs have actual seconds of delay- and even navigating in a word document becomes almost impossible.
I have only tried a few TVs and haven't seen a lag in the seconds range. It seems strange that there would be such a long lag - unless maybe on purpose to make the TV unusable as monitor. I wouldn't put it past some manufactures doing something like that.
I have heard some gamers use old fashioned analog TVs for the immediate response rate. I would guess thats done less these days due to the limited resolution of old analog TV. I winder if anyone uses analog CRT monitors these days for minimal lag?
Really useful. Thank you
Glad you found it useful - I was hoping my experience with this would be of help to someone else!
Proper computer monitors can have tricks such as syncing the LCD (or OLED etc) refresh to the incoming video and have low latency video paths. Hardcore gamers love monitors that do. Freesync etc. TVs only run their panels at certain rates and process the incoming video to suit that rate. I've found that TVs often always have some amount of image processing going on even if it's all set to off in the setup menus.
This brings back memories of terrible cheap CRT monitors where they would use phosphor dot pitches more suited to colour televisions than PCs. I think the worst I came across was 0.39. It wasn't unusual for them to use bottom shelf transistors in them in general were horrible and had trouble with readability of 800 x 600. A 0.26 CRT with high bandwidth video amplification (the transistors etc) could readily display 1280 x ? and be completely legible if somewhat small.
My now ancient Dell 24" monitor is on the way out, the LCD is starting to delaminate so I'll be looking into a replacement for it in the not too distant future.
I sure remeber those 0.39 pitch monitors. And somehow 0.42 even sticks in my mind. Crazy but with things so expensive back then savings here and there sold monitors. If you have the space, I highly recommend the LG 43" 4k monitor I have. I cant tell you what its gaming response time or suitability is or color correctness, but for hw sw development - wow - and cheap!
By the way - speaking of CRTs, you might have noticed retro CRT monitor to the right of my LG 43". Still like it best for photo editing but I must admit I'm not sure its better than modern LCDs these days.
The main difference I noticed between TVs and monitors is the pixel density. TVs are meant to be viewed at a distance of 6 feet more away, while monitors are meant to be viewed at about 2 feet. A 2k TV at 2 feet looks very coarse - you can see the dots, and things aren't nearly as sharp as with a monitor.
Yes - you really need 4k for anything bigger. Having said that, the monitors behind my electronics work bench are 2k but I'm always 4 or 5 feet away form them at least.
I am all ears!!!
!
The best thing about a 43" 4k monitor is that it is almost like 4x 21" monitors at 1920 with no bezel. So if you have logs you can make a long window that takes up all the length and then smaller windows to what ever you are doing with no gaps in the display if they were to cross a bezel on a 4x 1920 setup. I have found pc input on 4k tvs to be blurry and have input lag compared to a true 4k computer monitor.
Completely agree - exactly like 4x 21" monitors at 1920 with no bezel - you cant beat that for programming or other development work. Interesting you found the 4k TVs to be blurry and having lag - I didn't but was afraid those things would be an issue. I'm guessing varies from TV to TV. The main issue with a TV I found was the glossy screen and the reflections from it.
For some reason, a lot of TVs still default to having overscan enabled, so they're scaling everything to make it slightly bigger for the overscanning. That could be why it appears blurry. Look for a setting to turn off overscan, or "1:1" pixel mapping, or a bunch of other names each manufacturer uses. Another thing can be the sharpness setting. TVs all 'muck' with the video in some way typically, whereas monitors just display what comes down the cable.
@@gorak9000 Its funny you mentioned that - the LG hotel TVs that I have over my electronics bench had exactly that issue. You can turn off overscan, but after turning the TV off and then on,. it resets to overscan on again. I eventually found a setting in the "secret" installer/service menu to permanently disable overscan.
I get that for NTSC video inputs they would default to over-scanning, but if being fed a 4k signal you would think it would default to no overscan!
I myself looked into this last year. I thought of buying an OLED TV and use it as monitor, but I didnt do so for 2 reasons:
1. PIXEL DENSITY
Issue is that TVs are not in small sizes available. Manufacturers seem to do this on purpose I think. This to prevent people buying A TV instead of a monitor.
So you always are stuck with a large size TV. So if you use a TV instead of a monitor, you will be left with low dpi (pixel density).
2. REFRESH RATES
TVs just dont offer high refresh rates like monitors do. So for gaming you dont want a TV. For office applications, you have no issue here by the way.
You make a very good point "Manufacturers seem to do this on purpose ... to prevent people buying A TV instead of a monitor". I'll bet thats a big part of it - it seems like monitors that are the same size of as the same manufacturer's TVs (and seem very similar) seem to sell for considerably more than the TV. This probably is an indication that the business/professional monitor market is a lot less price sensitive than the home market. When you think about it, if you are paying a developer $100K (to use round numbers), a few thousand dollars for a monitor to make the developer more productive is well worth it and a relatively small investment. Bur a few thousand for a home TV really reduces the potential market size.
You might be able to coat a glossy TV's screen with a clear matte varnish.
With the right skills, your right. With my abilities, I would be afraid of messing it up :) Its also in a bad location with a glass door and windows in the worst possible position for reflections - I will probably move it to the other side of the room at some point and see how that works .....
Ok!! Now I know. Thank you. I have ZERO problem with the giant TV for a monitor. RUclips on a 60 " screen is going to be an improvement!
My face on 60"? Now thats scary :). I think with a monitor that size depending on distance you are from it, you may not be able to see the edges of the screen. But positioned right - would be great!
i use a 28" 4k monitor at work (windows) and a 50" 4k tv at home (mac). the tv obviously sits much further away, but that's a feature for me, because it leaves room for a piano midi controller in front of it and all sorts of other peripherals etc. the power-on time is a bit slow, like 20 seconds or so, but the input lag is unnoticeable - probably because it's a "dumb" tv that was $200 CAD on clearance at walmart years ago. i love my dumb tv.
The only reason I would not got for a 28" 4k is I prefer not to use glasses while working and well 28" with as much text displayed as I want on it, would make everything too small. But thats just me! Sounds like your cheap TV is a lot like the one in the basement that I showed glare with..
Byt the way - the far back bit is feature for me too - more place for stuff in front - in my case ekectronics being developed or tested.
I prefer to use TVs and I have to agree with you when you say that most of them do not have the ability to wake up with an HDMI input but I have found one which I still own.
Your lucky to have found one that wakes up. I wonder while more manufactureres dont make it a menu option - would be useful for so many devices and is really just a software change since they have the basic control board running to listen for the remocote control signal at all times.
So I'm curious - what do you prefer TVs? Is it the price or some other thing that I havnt thought of?
@@ElectromagneticVideos I use computer monitors as well as TVs but I prefer TVs when I need to go over about 22" because of the price. Right now I'm running a 2014 40" LED from Upstar, it is the one that wakes up correctly, a 32" Magnavox from 2004 that has just about every input connection used since the late 70s to now on it that I use for video watching and I'm typing this reply on. I have a 22" Samsung curved "gaming" monitor that I've learned to enjoy for its clarity as the only actual computer monitor I'm using.
After TVs started becoming high enough definition to start displaying text decently I've never really seen a reason not to use one instead of a monitor considering the price differences and most of my hardware is secondhand stuff that was busted I got for free and I repair whatever is wrong with it. Like the Upstar required a power supply board when I found it which was only $22 shipped instead of $200 at a pawn shop for the whole TV.
Perhaps a dumb question. But could one take a scotchbright pad and knock back the glare on a TV screen.? Might make a worthy experiment with a cheap TV...
That would just be scratching the panel (and in a very ununiform fashion) which is not analogous to just a transparent anti-reflective coating on the panel and would be more detrimental to image quality than of benefit.
Interesting thought but I would not trust my hand polishing skills to make it better rather than worse. And might make it moer cloudy - I think maybe the matt finish monitors have may have more rounded bumps than sharp scratch edges.
@@Desert-edDave I must respectfully disagree. Also, l never suggested to do it in a "random" fashion.
have you tried anti glare sheet on your tv
Thats an interesting idea - didnt know they made such a thing - will have to look into it - thanks!
Post-calibration results are ultimately what matters. TVs generally are inferior in response time and color accuracy, using cheaper lesser quality panels which are almost always VA panels. Hard to beat a nice IPS panel monitor. :) If quality doesn't matter, a TV may be sufficient for a given purpose.
FYI 1920x1080 is known as '1080p' which is what that 43LX570H-UA TV is. A '2K' display is known at QHD / 2560x1440 / 1440p, which is wasted on a TV as TVs conform to ATSC standards which you will find are 1080p or 4k today.
Yes - your right - it all depends on the use and for plain old hw sw development color or image accuracy isnt that great a concern at least to me. Thanks for 2k vs 1080p note!
2560x1440 is 2.5k
@@AndrewBerezovskiy OK - I got that wrong!
how about dpi? my g9 samsung has 5K and 120+ dpi my 4K tv 55 inch only 80 something. from close distance tv , even if it is oled look worst....
Proper viewing distance matters, especially when talking pixel density. Visible pixelation from viewing 'too close' is undesired, whereas superfluous pixel density is of no benefit.
Well the 4k 43 inch tv and monitor have about the same dpi as my former 22 inch 1920x1080 monitors - essentially 4 of them would cover the 43 inch one and combined would have the same number of pixels and dpi. Thats fine for my eyes, but for younger eyes a 32 inch 4k might be better.
Dear Sir,
I did an experiment dividing the 220ac voltage using 5 resistors with same size, but the results of the ac volt measurement were not divided by 5. Why did that happen? 🤔
That could be a bit of dangerous experiment if someone wasnt careful - please be careful! Are you putting a load across any of the resistors? If so that will drop the votage across that resistor. Or if they are high value resistors the voltmeter could be causeing the voltage on the resistor(s) its measureing to drop.
@@ElectromagneticVideos
Ia am using 5 Resistor 100k Ohm.
All measured 200 V AC
R1 : 33 volt ac
R1+R2 : 62 volt ac
R1+R2+R3 : 94 volt ac
R1+R2+R3+R4 : 138 volt ac
No Load accross 5 Resistor, just resistors only. I unplug every measurement, To minimize hazard.
By Theriocally should be:
40vac - 80vac - 120vac - 160vac - 200vac
Why is there a difference in theory and measurement? 🤔
@@jain461 100K is a high value - the voltages you are reading are depressed. I'll bet its the current though the voltmeter that is pulling down the voltage when you measure it.
@@ElectromagneticVideos Well then what is the recommended maximum resistor size? so that the volt meter can measure as it should?
Is there a minimum amperage needed to measure voltage with a multimeter?
@@jain461 Well it depends on the resitance of the voltmeter. Your drops seem to be in the 20% range so that would imply the voltmeter is drawing about a fifth of the current of the resistors. So its resistane might be on the range of 500k. Seems a bit low for a modern digital voltmeter. But assuming that value you can calculate how small the resistors need to be for whatever drop in voltage is the max you want to tolerate. Of course you have to consider that smaller resistor values will draw more current and so heat up more - be sure resistors have large enought power rating.
So what are you doing this? Trying to make voltage measurer for someting?
I understand why you REALLY need such a large computer monitor...you need all that real estate for all of those desktop icons! lol
You figured it out! That absolutly is the real reason - my big secret is no more :)
@@ElectromagneticVideos It's crazy that you still have uTorrent installed....I thought that became Malware almost a decade ago.
Why is it called a TV “set”?
You know, I never thought about that - good question! Maybe it dates back to the origins of television and "television" was the concept and so you had televisions studios, television stations, television antennas and television sets, and now having shortened it to TV we have often dropped the "set" part. Now why television set as opposed to television receiver? Maybe someone reading this knows?
@@ElectromagneticVideos Nobody on the Internet seems to know but there are a lot of answers like this: “Crystal Set… You'd get a crystal, a spool of wire for an antenna, an earphone, and
either you'd wind a coil out of the antenna wire for tuning, or in the
really expensive SETS, you'd get a variable capacitor!!!” I.e. radios were originally built from kits which were a “set” of parts. Not sure I buy this…
@@ElectromagneticVideos I think I prefer the theory that a “radio set” was originally a receiver and a separate transmitter, and that this semantically drifted to include receivers on their own.
@@AdrianBoyko That probably is it - certainly makes sense - and maybe even the "set" part included the batteries and possibly the separate antenna as was common back then and you mentioned with the crystal set. It is a bit odd though!
I strongly agree and disagree with pretty much everything you outlined... I have been using large format displays and projectors for PC for 20yrs now and for basic text documents, browsing youtube and stuff that most smart TVs can already do without a PC is great on a budget TV screen. As soon as you bring in gaming or photo/video editing its a whole different kettle of fish..... If someone is playing indie games on a $300 office PC made by dell or lenovo 5yrs ago and it has a low quality display and you have a TV spare pair them together 👍 but if you're building a system to play modern 4k games or anything like that then you're absolutely shooting yourself in the foot and flushing money by making the last link in the chain thats delivering everything to you a weak one and can be missing out on so much its kinda really crazy and I can not emphasise enough how much you're degrading the quality. Its like listening to fine opera on a pair of $5 near blown speakers that rattle, you can hear it just fine and enjoy it bit I would not recommend someone invest hard earned money into it based on the fact that I have enjoyed music on bad speakers.....
I think you should borrow an OLED and fire up a game side by side on your display and the OLED and also a movie at night with lights down and check out the difference 👍 I have had mine years and it still takes the breath away that screens have advanced so much in my time looking at them 👌 best money I ever spent and was cheap used.... I'm not saying this video is bad cos you made fair point in saying go give one a try but I think some point should be made especially with 4k and $$$$ computers to run it that don't just go try your mates screen they think is good and buy it, go experience that an OLED and some other things like Full Array Dimming and Mini LED as there are amazing options for all budgets and use cases.
Audio level is great, but voice is bit muddy, dunno if its mic, lack of room treatment or just distance too mic giving a deep voice extra presence thats not needed but I was cocking head like a dog a bit to earball some words. I do have damaged ears and my speakers do have powerful low end but other audio from low voice people sounds just fine. Better quality lapel mic might be a good investment if trying to get audio as good as possible for all to hear 👍 is in no way bad at all but to a picky ear thats just what I'm hearing and video overall is pretty bloody good for what its intended for.
I should also point out that goes for modern Consoles, PS5/Xbox that run in 4k and games cost $100ea... Low end screens are a super waste or your hardware and money less its the absolute only option you have.
I'm amazed you have been doing this for so long - certainly the displays now are way better than back then. Having said that, my living-room TV is is a real Plasma TV from that era and had a really great picture - not as high a resolution, but for viewing movies its great.
Your point about about games - its funny - a lot of people don't understand that gaming is about the most demanding computer use there is in in terms of processing speed, video requirements etc. Luckily I don't do much gaming so I don't need that expensive stuff!
Audio - appreciate the feedback - I have been gradually improving it - the biggest issue right now is the fact that my house is not a studio and has noises, echos etc that have to be dealt with. I have found that with me moving around lav mics dont work - they always end up rubbing on my shirt. The best mic so far is a Shure headset mic - close enough to minimize room noises, and always well positioned. There are higher quality headset mics which I might try sometime!
