Hey Folks so as the Tile suggests ive build my new System Everything is working great Windows installed Flawlessly as well as the GPU,Monitor,Chipset drivers etc although i have a big problem when i Go into the Display settings the max Resolution i can Select is 1920x1080 my 34 inch Ultra-wide is 2560x1080

Ive Attached Photos below so you can see what im on about Ive Also installed the Windows 10 Monitor Driver to see if that would help im using the AMD 17.10.2 Driver and my Graphics card is a HD 7850 2GB using a HDMI to DVI-D adaptor as that worked with my Previous GPU and Windows 7.

Also when i go to create a Custom Resolution it says my Display is not Compatible

Yep Its displaying my Monitor Model fine and it runs at 2560x1080 in Safe mode be it looks bad.

Going to try Updating my Motherboard Bios to the latest version.

The GPU is just Temporary en till i can get a RX VEGA AIB card

Tried using just the HDMI port but it doesn't display any image think it could be a Faulty port might try Display-port if my cable is long enough

The cable works fine through the DVI Adapter
