Try booting up in Windows safe mode by first restarting the computer and tapping the F8 function key right away. Hopefully you will get a usable display showing boot choices. Pick safe mode and let the boot complete. You should still have a usable display but it may be at a real low resolution.

Right click on an unused area of the desktop and you should get a pop-up menu. One of the choices should be "Screen Resolution" (at least it is on my Compaq desktop PC). Select it.

You should then be able to adjust the settings to match the specifications of your display. You should also be able to test any of the settings without worrying about the monitor losing signal. Windows will output the new resolution and show a text box with a button that lets you confirm you want to use the new settings. If you don't do anything, Windows will go back to the old settings in 15 seconds.

EDIT: If you still have a problem, please post the exact brand and model number of the Video Controller card that uses the ATI Radeon 5870 chip.

hi,

well i have managed to get the hmdi to work once i got a new 40 amp power supply and a better hdmi cable, not sure which one fixed the problem.

but now the screen looks worse than dvi and looks blurry and the color is too much. dvi looks a lot better.

does anyone know why the picture is so bad and how i can improve it please?

just letting anyone know that i think i have solved my problem, i just fiddled with the monitors sharpness and color and stuff. it looks alot better, although im not sure whats better DVI or HDMI. guess it will take time for my eyes to get use to the HDMI.

anyway i will mark this as solved.

thanks
