I like the informational screens in this video. Especially the explanations of the composite signal with the little coloured Doctor Volt Lego figures. Very nice to look at.
I've wanted to see this done every time a youtuber makes some clickbait video showing modern hardware being displayed on vintage television by using an absurd daisy chain of adapters into an rf modulator.
If I see it correctly, RGB are mixed with the same resistance value? That's why there was no difference between the RGB bars on the test image. To improve this, the resistors should be chosen in the ratio: y = 0.3 * r + 0.59 * g + 0.11 * b. The values do not have to be adhered to exactly, it is sufficient if they are approximate. 0.3* r + 0.6* g + 0.1* b
i have a Philips brand radio model TV. The code is 10cx1130 / 02s. The cathode of the tube came out. There was a gas sound from the back. I was afraid that it was broken. I disassembled it and cleaned it completely. What happened when I put it back together?
Yes, this is only possible when the grapic card supports interlacing. It is not difficult to find the PAL or NTSC timings. They can be found on Wikipedia for example. So I didn´t do the extra work to provide them.
ok so i managed to obtain a samsung crt tv from the 2008's it has RCA component input(red,blue,green) and composite input (yellow,white,red) also an s-video input and a SCART input my laptop has HD4000 with a VGA basically i need to write bits to video memmory? when i connect vga to component input the notebook detect the display, but no image on tv...what should i do?
Great content but it can be dangerous for the laptop and CRT because when you change frequencies, the electron gun can also fire in the areas where there is no phosphorous which can damage the Tube. Still impressive work technology standpoint. Cheers ✨✨✨
The best most practical info on recycling these devices!

At last! Someone who knows what he’s doing! Thank you
I love any projects an experiments with CRT TVs. :)
Awesome ! Love this solution !!!
Good work

Yeah, but at least you need an Arduino

You are right. I didn't think of this.
0.3 ohms resistor can you provide a example?

It seems that the CRT has sucked air. So it will make no sense to put it back together as it won't work anyway.
You do not need any Arduino. Just force a monitor in Windows config and voila.
How can I do that? Under Windows 10 I could only choose modes offered by the monitor. But maybe this is possible with older Windows versions.
@@DoctorVolt Thats because u are using intel GPU, with Nvidia or AMD u can create very detailed custom resolutions.
Awesome! So, in the end you just displayed using standard PAL signalling. Could you provide the Detailed Timing Descriptors values for others to use?
Yes, this is only possible when the grapic card supports interlacing. It is not difficult to find the PAL or NTSC timings. They can be found on Wikipedia for example. So I didn´t do the extra work to provide them.

Find out if your graphics card supports the timings for NTSC PAL. Then write the EDID bits as I did in the video.
Brillant! :-)
How about color TV
Great content but it can be dangerous for the laptop and CRT because when you change frequencies, the electron gun can also fire in the areas where there is no phosphorous which can damage the Tube.

I took the risk with my old laptop. And gracefully everything survived.
Brilliant
epic!!!
Github code? Diagram?

It's amazing how TV manufacturers charge more money for red, green and blue output.
