Widescreen Gaming Forum

I am running a duel boot system. Vista 64 for work and Win7 for play, both operating systems have their own hard drive.

Vista 64 us using 9.12 Catalyst and thats where it stays. Eyefinity with three monitors at 4800x1200 works perfectly fine with my Vista 64 boot.

The 10.1s were working perfectly fine with my W7, but I decided to give the preview 10.3s a try and now I got major problems. After installing the 10.3s my computer would boot up and I would hear the W7 intro sounds but I had no picture and my monitor was displaying the default message saying it does not support the monitor signal, please set monitor to 1600x1200. I unplugged two monitors and it boots up fine to 1600x1200, so I plugged in the second monitor and it registered it, then I plugged in the third monitor and all three screens go black. If I reboot with one or two monitors plugged in it will boot up W7 just fine and I can go into control panel and group and bezel manage the two monitors, but the minute I plug in the third monitor everything goes black!

I did a massive driver sweep, driver uninstall, even went into regedit and took out everything ati/amd. Then I reinstalled back to 10.1s and I get the same problem!!!! One and two monitors will work, but the minute I plug the third in all three screens go black. The same thing happens when I reboot with three screens plugged in with 10.1 it says monitor does not support resolution please change display to 1600x1200!

I know its not a hardware issue because everything works fine with Vista64, Im typing this on the third screen now!

WTF is this SH1Y!

In Summary: 10.1s worked fine with W7, installed 10.3s and third monitor does not work and causes all screens to go blank when tried, deleted and swept every driver, cleaned out regedit, and re-installed fresh 10.1s and third monitor still does not work and still causes all three screens to go blank!

I am using a sapphite 5970 and three dell 2007fps

did you try a system restore?

No, Ill just wait till the final 10.3s come out and then try them and if they dont fix the problem then I will do a restore or reinstall

IDk man, i think it would be easier to do a system restore now, before you have any work that u have to back up.

yea but a system restore aint gonna help because I had wiped all of the drivers and even cleared the regedit :(

Did you try to switch the cables? Screen 3 becomes screen 1 as example? This way, windows 7 should reregister the screens and you can setup the screens again. You can switch back afterwards.

I got it working. I booted with two monitors, then made a group of them in CCC and then plugged in the third and it worked. Don't know why it finally worked but I am pink as punch that it did. The immersion in games is noticeably better with bezel management!
