AMD system, upgrade from windows 7 pro, at end of install, screen appears at 1080P, in order to use my taskbar, I have to use the scaling and drop 8 points to fit monitor. If I try any other BASIC resolution, one of 2 things happen, I end up with a SQUISHED desktop with 4 inch boarders on each side of the monitor. It seems that only the 16:9 or 4:3 is being used. Have tried 6 different ways of installing AMD graphics drivers, NOTHING changes.
Monitor is a ViewSonic x2433, video card is an MSI HD7870 Frozen with 3GB DDR5, connection between card and monitor is HDMI. Have spoken to Microsoft and they really have no idea what in windows 10 can be doing. Windows 7 64 pro install using 15.7 drives works perfectly, all resolutions and screen ratios are available, default desktop is 1680x1050 @32 bits. Also noticed 8 bit is the only selection I have in the Catalyst center.
