I have been using a custom build with a HD 4650 graphics card for five years and recently updated to a R9 380 card. When I open games that I have played before, they now are full of lines and poor color. Its so bad that I cant even navigate most menus in the game. I have managed to stumble into a different (lower) resolution with the same ratio 16:9 and the picture is clear but does not fill the screen. I am using an acer monitor with HDMI cable (2nd monitor with a DVI cable). All settings for my display are set to 1080 resolution so i'm stuck. Help please.
Windows 10 64 bit, Penom II X2 3.2 GHz, AMD 770 Chipset
