I was dealing with an issue through AMD's forums, but they haven't responded back in about 5hrs now. So hopefully you can help? Here is the original issues i was having; I have been receiving a message on boot that; Couldn't Load HydraDMH.dll?? So I decided to check for updated drivers for my card to see if that would correct problem. So I went to AMD and downloaded autodetect. It then checked my video drivers and OS. It found that there was an update that should be downloaded. It showed to download 11-2_vista64_win7_64_dd_ccc_ocl. I went through the procedures to download and install. Everything installed and restart computer my screen is messing up. Lack of better terms. It is full of vertical linesall the way across screen, and colors don't match background. And screen is quite offset to the right. I was connected to my monitor with Monster HDMI cable, which was working fine before download. I disconnected it, then attached DVI cable, screen came back perfect??
They told me to; Uninstall your old drivers using your computer control panel / uninstall a program. Express uninstall all AMD software including the installer. Reboot. Run Driver fusion (free) http://treexy.com/products/driver-fusion select AMD graphics and delete all it finds. Reboot. Install the latest driver suite for your card including the dotnet4. Reboot. You should be good to go.
Which I did all that to the T. The couldn't load HydraDMH.dll, hasn't came back but still have problem with HDMI. When I try to use the recommended max resolution 1920x1080; it has vertical lines all the way across screen and colors are messed up. It does work fine as long as I'm not setting it to 1920X1080 in HDMI. But I can use max resolution on DVI connection?
