I've got a Relisys 1720 LCD TV with a native resolution of 1280x768. When using it with my PC I can't get the phase setting exactly right, so the picture quality is always slightly degraded. This is best seen by displaying a chequerboard pattern, and there are flickery wavy lines all over it, which I can never entirely get rid of by adjusting the monitor's phase setting, unlike with my other LCD monitors. I've tried several mode definitions, but can't get a perfect picture with any of them. Does anyone have a suitable X modeline or Powerstrip settings for it?
