Ok I have installed win 10 on 6 different computers. I have this same problem on my Dell Inspiron and Dell XPS laptops. Both have the ability to Display at a lot higher resolutions (they were set there before install) but I cant seem to get the resolution to go above 1366x768. I have removed and reinstalled the newest drivers for the graphics cards. I have even installed old ones, but to no avail. The highest resolution available is 1366x768.
