Here's a bit more detail, I read recently about mods on old graphics cards to bypass low pass filtering performed on the analogue outputs. This low pass filtering was designed to reduce RFI, but a side effect was that it degraded image quality. I have some CRTs still in use that require analogue video, and an old GTX 260 lying around that I don't mind sacrificing.
These old mods are documented here:
Can anyone help me adapt these mods to the GTX 260? I assume that they still apply.
I've attached some photos of my PCB. The video outputs on this graphics cards from top to bottom are HDTV out, and 2x DVI-I. I believe what they call HDTV out is component video output over a mini-din connector, a breakout cable is supplied with the card.
