CRT Emudriver - Multiple CRT TVs
« on: January 23, 2025, 09:16:35 pm »
Guys, I have a question;

I have a PC dedicated to the CRT Emudriver with an AMD R7 240 GPU that only has one analog output. The question is: I'm about to buy another CRT TV dedicated to vertical gaming (TATE) and I would like to know the smartest way to connect the new TV to my GPU. Would it be easier for me to buy a component cable splitter where the GPU would send the same signal directly to both TVs? I count on your help. Thanks!

Hi
Another option would be to search for an extron mvx XX vga where XX are 2 numbers that indicate how many inputs and outputs it has.
For example extron mvx 44 vga with 4 inputs and 4 outputs.

Adding displays without signal amplification means a weaker image on all displays. There are extrons and switches and whatnot that can do this for you.

If you are keen, you could build a basic video amp for a few bucks out of the THS7314/7316 or THS7374.  These ICs are video amplifiers theoretically capable of outputting at high enough levels to serve two displays at once. I'd probably build it a little differently, but it is a good start and should work. Might be a bit mcuh for most people though.

If you don't need both displays at the same time then maybe a KVM switch?

I'm currently have Radeon with two analog outputs but for the future I'm planning motherboard with two PCIx16 and two graphics cards. Configuration untested and it will be a bit expensive but should work in theory.

Assuming your TVs have RGB SCART inputs. (Depending on your setup, a SCART switcher with 2 outputs might be a better option, though.)


You can use the HDMI out on your second 15 kHz TV, anyway, but that requires a DAC which supports 15 kHz, and I don't think they're easy to come by (would love to know a good one which is still available, myself). Two outputs has the advantage of letting you use two actual monitors for games with two monitors originally and the drawback of having to tell Windows (are you on WIN?) every time you swap displays.
