Xorg, refresh rates, modelines
GenuineAdvantage:
That's exactly where I went in trying that stuff I said before, but:
Ok, scratch this, I've learned the unfortunate fact that that 120Hz rate on windows was actually interlaced. So it was really only 60 fps. I'm just assuming X doesn't give you interlaced modes? Either way it's not that great of a monitor after all! Anyone recommend a true 120Hz monitor?
Edit: scratch the X part, it does do interlaced
Modeline "1024x768@120i" 64.56 1024 1056 1296 1328 768 783 791 807 interlace
Edit: Looks like I spoke too soon, that's not the same and it's all screwed up. I have no idea what's going on, if it's true 120Hz in windows or what. Oh well
Refalm:
Never screw with interlace modes when you don't know exactly what you're doing (I don't know shit about it either).
Also, I don't think GeForce 4 MX or most CRT monitors supports 1024x768 at 120 Hz. If you could in Windows, it was fake.
I think with the right drivers and running xorgcfg, you can get 75 Hz.
GenuineAdvantage:
The videocard itself can go 200 and beyond. I don't remember the number. If it really can't, then the nvidia's windows driver is seriously flawed. I'm doubting that much if they're on the list. And this monitor, I looked it up and from what I've read it can go up to 120 except at the higher resolutions. Otherwise, the info was false and windows was fake, but I will check that next time with those overclocking softwares which I forget the name at the moment. Are those fake? Either way, I'm about to give up on getting it down on here. I'm already at 85Hz so as far as the desktop, I can't see a difference going higher. But for games I hear it matters. But since we're talking about linux, what games? Old Quake 3 hardly's seems worth the effort now.
But still another reason I wanted 120Hz is because for running things like emulators it matches better. And as far as I can tell, vsync in OpenGL syncs itself to your virtual resolution, not your current one. If you know what I mean, if not it hardly matters. Speaking of that, if someone knows tricks to change this appearent behavior, let me know.
Aloone_Jonez:
I thin k Refalm is right, the monitor is normally the problem, I don't see any point in setting the refresh rate to anything higher than 85Hz and 75Hz is normally high enough to avoid flicker even if your eyes have a fast response time. Seriously though I think you should consider getting a TFT screen that way you won't see any flicker regardless of the refresh rate.
WMD:
Mine can go to 100Hz at 1024x768, 85Hz at 1280x960. Nothing can do 120 at a decent res.
