Devices:

  • Asus F8Sv Laptop (Windows 7 ultimate, GeForce 8600m GT, display driver is 301.42, detected and downloaded from nvidia.com, VGA and DVI output interface)
  • Gateway 23 inches LCD monitor (VGA, DVI-D with HDCP, and HDMI input)
  • 18 pins DVI cable, VGA cable, both new.

Problems:

When connect laptop to monitor by VGA, resolution is automatically adapted to 1920*1080; but when using DVI connection, resolution on monitor is fixed to 1024*768, which is lower than my laptop default 1280*800. The maximum resolution in windows control panel is only 1024*768, while the Nvidia control panel provides options 1920*1080p and 1920*1080i, but clicking apply button does not work, the resolution just can not change.

Possibly reason I guess:

GeForce 8600m GT does not support 1920*1080 resolution through DVI outputs.

Can anyone confirm it or give the real reason?


edit:

Problem solved by buying a HDMI to DVI-D adapter. Using this adapter and a HDMI cable, I can now enjoy 1080p movie.

The reference 8800M design appears to be able to output up to 2560x1600 via DVI, and has an integrated 1080p HDTV encoder. Make sure you have the latest possible drivers. –  Breakthrough Sep 9 '12 at 19:40
