Hi,
If a separate monitor (not a laptop) it will have Physical Geometry Controls on it so you can
move the entire screen and enlarge it if needed. Also Right Click a blank area of the Desktop -
Graphics Properties - look for Geometry settings (PC's and laptops).
If a Laptop Right Click a Blank are of Desktop - Graphics Properties - look to Horizontal - Vertical
and Geometry settings.
If needed contact your System maker's support and check their on-line documentation and any
forums. Do the same at the Monitor maker's if different from System maker.
Hope this helps.
Rob - Bicycle - Mark Twain said it right.
