I'll try to explain this as best as I can.
I'm using a monitor that uses 1366x768 (32in) and a 1680x1050 (22in) monitor, the 1366x768 registers fine. However for some reason I can't get the 1680x1050 resolution to stay.
I just got this computer today and the resolutions were working fine on my other pc using both monitors. (old pc uses win 7, new pc uses win 8)
When I first turned on the new pc with these 2 monitors the 1680x1050 resolution was not found, it only offered 1280x720 and 1920x1080 - neither one works well at all.
I uninstalled the hd 7570 graphics drivers from device manager and installed the latest hd 7k series drivers from AMD and it instantly found and automatically selected the 1680x1050 resolution. However, within about 5 sec both monitors went black for a few seconds and when they came back on there was no longer an option to select 1680x1050 and I was left with only 2 options as mentioned above.
Anyone know why this is happening? I can get it to work by doing the described method of uninstalling the driver and then reinstalling from the download I got from amd, but it only lasts for a few seconds.
