Using HDMI Can't Go Above 1024 x 768 Res on Windows 10

Hello all, I have a strange issue I'm hoping you can help with.

I just bought a LG 27MP48HQ-P 27" Monitor, and it has a VGA and HDMI input. It's max res is 1920 x 1080. I connected it to my Windows 10 desktop via the HDMI port of my Gigabyte Windforce 970 graphics card. The res was stuck at 1024 x 768, but I figured I could install drivers for it. The drivers supplied by LG on the CD did not work, it said it installed the driver but when referencing Device Manager I still had the generic non-php monitor driver. I also tried downloading from LG's website for that exact model, with the same result. It is a strange driver setup, you run an executable and pick the model, then it just has a popup that says "driver installation successful."

I've tried manually updating in Device Manager by browsing to the driver file and installing, but that makes no difference. Rebooting, searching online through Device Manager, and un-installing and reinstalling the driver in Device Manager don't work. I'm getting really ticked at this, it should be simple, but it isn't. Any help would be greatly appreciated!

Interesting. Well, the monitor sure appeared to be displaying 1080p, because it was really bad res and then when I changed it on the xbox the display changed and the picture seemed to be pretty decent, high res.

I did try custom resolutions, standard 1080p specs, and it resulted in a flickering black screen with some strange colored lines. Obviously, that didn't work. Also, madmatt's suggestion was rather the same as similar suggestions... I still only have access to that frickin 1024 res option.

By the way, I do appreciate all the help everyone has given!

Your final test would be to find a computer with HDMI, then connect your monitor on it. If it displays at 1080p, then your software or GTX 970 are the issue. If it stays at 1024...it's the monitor.
