Just some suggestions...
Does changing the icons (rightclick desktop "View" large, medium or small icons) or changing the screen resolution resolves the problem?
Otherwise try "All Settings" "System" "Display" "Change the size of text,..." and move the slider to a different position and "Apply" and see what that gives you...
Also you could try "Calibrate display" in "Color Management" "Advanced".
Or try a combination of the above !
