Also here is a screen of the specs for the card.

Yeah, I'm definitely going to have to re-install windows after this mess. Visual Studio is giving me issues so trying to repair it and just realized my language for it is now Russian and when I try windows updates it thinks its Russian. SMH What a nightmare. I would not recommend using the DDU 3rd party app if you really dont have to, you are better off just uninstalling them all manually. Disable windows automatic device install and go to device manager right click uninstall device and be sure to check "Delete the driver software for this device". Which I recommend to do first. As far as SLI I haven't seen this exact issue with it my self, hopefully someone else can verify that. I just dont understant why cross fire would limit the refresh rate to 30 Htz.

Posting from mobile. PC Specs Rampage IV Mobo i7-4960x 40GB ddr3 1333Mhz 2x MSI AMD R9 280x - Cross Fire Windows 10 Pro I just recently picked up the 38UC99 Monitor, had to also go back to purchase a Mini DP to DP cable. The issue I started to have right away after updating my AMD crimson drivers to the latest and hooking up the Monitor is I'm locked at 30Hz which is terrible. I thought it could be due to driver issue so I decided to do a clean install of my drivers using DDU (which is posted by AMD yet they say use at your own risk) luckily it created a restore point because after running that tool I was not able to install a single driver. I was receiving errors every time I tried to install a driver whether that was for the GPU or just a random device . So after a few hrs looking up those errors running; check disk, sfc scan, repair, and image repair which didn't solve the issue of drivers not installing I was left to restore. (now I have other issues which I just plan on reinstalling windows at this point.) Pretty pissed cause I should be able to achieve at lest 60hz I manually uninstalled all the drivers from device manager by forcing removal of the device and checking the 'Delete the driver software for this device' which took some time. After which I cleared out the registry for display adapters etc and finally was able to do a full clean install of AMD drivers. To my surprise I'm right back to square one stuck at 30Hz so yeah at this point I'm pretty pissed. So things at this point that I have done include the following: Buying multiple Mini DP to DP cables (To ensure I didn't have a bad cable) Update Windows 10 with all the latest updates. Installed the latest AMD crimson drivers. Uninstalled all AMD drivers using DDU (Worse mistake of the day) Restored using restore point Manually uninstalled all AMD drivers from device manager using 'Delete the driver software for this device.' Cleaned the registry of all old displays (1 had 6 23 inch 1080p Acers) Installed the latest Motherboard Drivers, Chipset drivers, audio drivers, Bluetooth etc. Updated my bios to the latest bios available Updated Windows 10 to latest updates (Not including the Creators update) Installed a clean / fresh version of the latest AMD Crimson drivers. All of which left me with the same results stuck at 30Hz. After trying to shutdown the computer I ran into a new issue, the computer refused to shut down or restart and would get stuck on the "Please wait while shutting down." screen. Wtf I knew this had to be gpu related because with no drivers installed the computer worked fine. After hitting up google its search reveals AMD has had a know issue with this while the cards are in cross fire. So I removed cross fire as I'm tried of reinstalling drivers and the fix posted was a bunch of crap to follow. Load and behold. Cross fire was my problem the whole time. I have finally achieved 75hz at 3840x1600 and the computer shuts down and restarts correctly. So I plug back in the cross fire cable to verify and sure shit capped back at 30Hz and can't shut down or restart. I have tested both cards and they work fine independently and are able to achive 75hz at 3840x1600, but as soon as I place them in cross fire I get the following issues. Windows will not shut down properly - stuck at the please wait while shutting down. Windows will not restart properly - stuck at the please wait while we restart. Monitor is capped at 30Hz So so why does cross fire cap my refresh rate at 30Hz. Well more like 27.something hz? Has anyone else run into these issues or know a fix that would solve these issues ?
