@beardalaxy It even squishes a 4:3 signal into a 1:1 image? I can only suggest getting another adapter. Besides, if it's transforming the image, it's probably buffering the image (increased latency).
This autismo has a guide for CRT TVs, basically you need a VGA output and an adapter that converts VGA into component. He uses an old GPU to get a VGA output but this is a meme, you can simply get a displayport to VGA adapter and these typically don't buffer the image.
