Maybe I'm an idiot, but what's a good way to get csync from a GA setup? Even with the old ga I couldn't do it and it was frustrating because that's what my monitor wants.
Substring:
I'm.not so much into signals, but how isnit different from combining hsync and vsync ?
arfink:
Everything I've read online is people getting all armchair-expert and saying it's not as simple as just bridging the H and V sync lines, but haven't been about to figure out why or how these people expect it to be done properly.
Substring:
well, for 10€, my spanish VGA2SCART does the most basic CSYNC and it does work.
@Calamity of course nvidia and intel can work, but never at the original resolution, or even something hardly close. Unless fancying with super resolutions the same mess as on windows, but I don't think it's really usable the same way as on windows, are thse GPUs worth ?

Super resolutions work the same way on Linux, and it's anything but a mess. Intel gpus are crap and Nvidia is a horrible company but they can run GM on Linux with zero compromises. You do have compromises regarding frame buffer and desktop resolutions, which will make setup harder unless you know how to bypass the issues.
Since you can scale horizontally to meet dotclock requirements, as long as you keep the vertical resolution, you're still "pixel perfect". One might have a valid objection to using super resolutions because of fractional scaling, but in Linux you can be smarter by just setting -dotclock_min 25.0, which will automatically promote the horizontal resolution to the first multiple that meets the dotclock, and still use integer scaling. Signal-wise, the result is identical to using "native" resolutions, it's absolutely the same thing. And the advantage is that geometry is better in general since the granularity for adjusting blanking gets much finer.
