So I just updated my pc to 8.1 and now my HDTV I use as one of my monitors won't display the correct resolution. The HDTV doesn't display full screen anymore, there are 2 inch black borders all the way around the screen now and it doesn't fill the whole screen. My acer 1080x1920 24 inch monitor connected via VGA cable works fine. The HDTV is connected via hdmi and it is a Emerson LC391EM3 1080X1920 60h. The pc uses a AMD A6 5400k APU. Any idea how to get the HDTV to display correctly without going back to windows 8.0? I tried to update the graphics driver but it said the driver was up to date. Any help you could give would be great. Thanks.
