Hi-

After connecting my Westinghouse LVM-37w3se monitor (its brand new, does not have bad EDID issue) via DVI cable to 8800GTS card (ForceWare v158.27) with Intel Q6600 @ 2.4ghz, I cannot find 1366x768 resolution in Windows XP (SP3)?  The native resolution is 1920x1080p at 60Hz (16:9), but the manual says it should be set to 1366x768 for best performance. Does   only the VGA connection allow a 1366x768 resolution? Currently I'm using 1280x720 and it looks okay. Information from MonInfo follows:

I'd suggest that the manual is just plain wrong - maybe its for a different model. The Westinghouse firmware clearly does not support 1366x768 and since it has a physical resolution of 1920x1080p there would be absolutely no reason for them to support 1366x768.

You should run this at 1920x1080 and only at that resolution.

The "Quick Connect Guide" said 1366x768 in a footnote, but is clearly outdated and wrong. I'm running the monitor at its native resolution and it looks great! Things are easy to see after some minor changes - dpi setting to 120, cleartype, etc.

Thanks Rik!  Tongue
