I have the above monitor and a Chaintech FX5200 64Mb graphics card. Every so often the screen freezes and I need to minimize the active window. This results in a black sceeen for a second or two and then it is OK. It happens more often when on the Web. Have had system crash (rarely) back to 4 colour screen and error message for graphics failure. Card checks out OK.????
Just had another thought. If your using XP and have downloaded the driver update for nvidia it just might be this that is causing the problem, it made my TFT freeze and go to safe mode.
From the adaptor tab click on properties/driver then click on the "Roll back driver" button. this will revert back to your original card settings. I did this with mine and it works as it did before. Perfect!
It oly offers 75htz at 800x600. I tried the downloaded nviwia driver with no success and have rolled back. The DVI lead instead of analog left me with an error for 'check the cable' no video floating in a beautifully coloured but less than helpful bix so i swapped back again. My driver disk says To choose the exact named driver and offers digital or analog but if I load the Digital one i get no picture Ray
