Problem with resolution

[Arrri]

I have ATI Radeon HD7970, Dell monitor with max resolution: 1920x1200 and windows 7 64bit.

On starting computer:
1) BIOS - all displayed OK
2) Windows loading - all displayed OK
3) Logging in screen - not displayed - monitor is telling me, that best resoultion is 1920x1200. It looks like graphics card is using too high resoultion.

All I can do is putting computer to sleep, waking. Then all works perfectly.

did you download your graphics card driver? try that.
if that doesnt work go to Control Panel> Appearance & Personalization>Display>Adjust Screen Resolution and set resolution to 1920x1200 in dropdown box

Reinstall your amd 7970 card drivers.
