monitor benq

Cant adjust teh vertical position of my BENQ monitor?
I am unable to adjust the vertical position of my BENQ monitor, the whole screen is shifted downwards so i cant see the start menu toolbar and when i try to adjust the vertical position, it remains stuck at 255 and wont budge. However when i change the horizontal position, it changes normally
Went on a web search and I think I found you on one site, persistence, good for you. Do you have your manual on the OSD for your monitor? Your might want to read it again.
If you don’t have it handy Here is a site: http://safemanuals.com/brand-user-guide-instructions-owner-manual/BENQ. Have you tried to change the resolution, then go in and change the vertical? Had that problem with a CRT that eventually went bad. (It was almost 15 years old, it did it’s job).
Good luck. You might try posting the question again.
