DG45ID and TV. Wrong resolution after wake up

idata · ‎02-19-2010

I have DG45ID G45 graphics connected by HDMI to TV Sharp D77X. I almost always get 1360 x 768 resolution after wake up from S3 - looks ugly compared to native 1960x1080@50p. Only if Media Center was in full screen before sleep. If, after wake up I close Media Center app, all reverts to normal.

How to fix it?

What OS ? What graphics driver version? What MB BIOS?

Hi. OS is windows7 64bit, fully updated. Graphics driver is one that windows downloads by update, not sure what version. I tried latest Intel's but got some problems with DVD playback. Rolled back. MB bios is 0113.

Hi. I did some research.

MonInfo EDID info shows two DTDs: 1920x1080p@50 and 1360x768@60. Now question is how to totally forbid the driver the use of any other mode except 1920x1080?

I don't believe that there is a way to delete the supported resolutions.

I have seen the problem that you are experiencing in the past and it was because of a bad cable, the computer recognized a different monitor every time so it went to the lowest supported resolution.

Try contacting the monitor manufacturer and ask for the drivers, this usually will help

I am having a very similar problem with a very similar setup. I'm using Windows 7-64, an i3-540 processor (using Intel HD Graphics) hooked up to a Sharp TV and using WMC. It doesn't happen but 1 or 2 times a week. Any way to always force the graphics card to output 1080P?
