on that display tab on dxdiag half of the info is blank. win 7 will not pull any info from the vid card, which is an ati 4870. The card works FINE on win xp. Only win 7 is being an absolute pile of junk with ati drivers.
Any help on this? How can I correct the Direct x info to what it reflects in winxp(WHICH RUNS PERFECT)
Basic question, but want to make sure.... Have you installed the latest ATI driver for your specific card? You may need to uninstall the current drivers and do a fresh install, instead of just an update. From looking at the AMD site, it appears ATI issued new drivers for the HD 4870 (both 32/64 bit) on October 21.
I have ati 4870 and it runs beautifully on windows 7 64bit. I had trouble w/ my card running correctly on windows xp actually. I have latest catalyst drivers, and have not had any issues since I've ran it on windows 7.
Did you get a pop box saying the drivers installed correctly or install with recommended settings something like that.Did you do a driver update via Windows update.
