LC-26d5u and radeon x850 issues

by orkiss / August 1, 2005 10:33 AM PDT

I'm trying to set up my new sharp lc-26d5u LCD as a computer monitor. The tv/monitor has both DVI-I and HDMI input that I have tried to use. I bought a DVI-D to HDMI cable and tried that initially and it kind of worked...there was no boot up text on the computer screen when i turned on my computer, but I could logon to windows w/o any problems and it worked fine w/ displaying windows. (windows xp, sp 1). however, it will not play some games (battlefield 2, KOTOR 2). it blows me out of bf 2 before it even loads up, and there are display issues w/ kotor 2.

So i then tried a DVI-I cable and that displays the bootup text at 640 x 480 w/ 60 hz refresh, but it does not display any of the windows part. however if i restart in safe mode w/ vga enabled, it works, but only at 640 x 480, 60 hz refresh, if i change the resolution it goes blank...

I am at a serious loss as to what to do, i have read about people using the same HDTV as a monitor and it works fine for them (through DVI - DVI) Any help as to how to make it work via DVI so i can change the resolution and refresh rate or how to get the boot text and games to work w/ DVI - HDMI would be GREATLY appreciated. Thank you very much. Any answers can be posted to this thread or sent via email. Thanks again.

first, update your drivers. the newest drivers will offer better performance and might even solve your issues.

second, what is your power supply wattage? this is an important factor as without continuous power, games will crash.

can you post the rest of your system as a reference also?
oh, and why service pack 1? unless thats a typo, but i would upgrade to service pack 2.
