New System Build Monitor Resolution not Displaying in Windows 10?

[lloydcars18]

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

Change the resolution in the AMD Radeon Settings.

I've not seen this problem on desktop, but I have seen this on laptops. My first thoughts are to update the bios on your motherboard which seems odd but it works on laptops to fix this problem. The second thing is although you updated the driver for your monitor is the monitor displaying its correct model in display adaptor settings.

The next problem you are going to have is that your graphics card only has 2GB of video RAM. Driving a bigger resolution you are going to run out of video RAM very quickly. my old 680 GTX had the same problem even at 1080p I was running out and my frame rates were tanking.

HDMI is limited to 1920x1080p 60hz, but I would have thought there would have been a way to drive your screen at at 30hz to get the bandwidth to drive the extra pixels. The best fix would be to get a display port cable (assuming your monitor and video card have display ports).

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

I've just realised you are using a DVI adaptor. Take it out and throw it away . Connect your monitor using just the HDMI cable to your graphics 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

I've had a couple of HDMI cables go on me might be that.

The cable works fine through the DVI Adapter
