Radeon HD7970 Highest Resolution 1920x1080

Hello -

I'm in the middle of a new build for a desktop video editing machine and am running into an issue with my graphics card and/or monitor.

The highest resolution I can get from my Radeon HD7970 is 1920x1080. And even with that, It does not fill out the entire screen. I have black boarder of about 3/4" going around the outside of my Windows 7 screen image. I'm using a 1080P HDMI cable to connect to the Samsung Monitor (SMS23A550H).

What's strange is that I am also running a laptop via the vga connection to this monitor and it to will only go to 1920x180. However - the laptop fills the entire screen Windows 7 (Explorer?) screen.

I have the Radeon HD7970 installed in the #1 PCI slot (blue) of my ASUS P9X79 WS motherboard.

I went ahead updated the drivers for the MB, video card, and my Samsung LED monitor and have re-seated the video card and still can't get it full screen nor an option to try a higher resolution.

OTHER COMPUTER SPECS:

MB: ASUS P9X79 WS ACPI
CPU: Intel (R) Core (TM) i7-3930KCPU @ 3.20GHz speed: 4054MHz
RAM: Ballistix by Crucial 16GB (2 8GB Sport DDR3 - 1600 (PC-12800) CL9 @1.5V
GPU: MSI Radeon HD7970 OC Edition 3GB GDDR5 PCI-E 3.0 DirectX 11


Can anyone tell me what may be going wrong?

Thanks for any help you can provide.

  1. your monitor is an 1080p monitor, you cant go higher. Make sure you use the 1080p resolution and not the 1080i. I have a 720p monitor (can go as high as 1080i) and when i use 1080i the screen is not filled out, i have to scale it in the graphic driver software. Go to catalyst and make sure you are on 1080p and if you are scale the image.

    You probably just need to go into CCC and disable underscan. There should be a slider for it in CCC under the display properties tab or something like that - shouldn't be hard to find.


    Thanks everyone. The scaling did the trick. I must say though even after pointing me to the "CCC" I still found it a little clumsey to navigate my way to scaling. In any event it's fixed.
    Thanks to all for responding.
