SOURCE: OSD lock - I think
This is for Viewsonic LCD, but it's probly pretty similar for you...

Yes, a stuck key would be a likely culprit. Sometimes a key will get stuck out of just plain useage/wear, or, pop or other liquid spill or splatter will result in a sticky key. Press on the suspect key-compare to another key- different feel will tell you a problem exists.
Low cost keyboards don't generally have the life expectancy as older higher quality ones. Laptop keyboards are also more fragile, and subject to problems.

Please try to Turn the monitor off. Hold down the Menu button while the monitor is turned off, then press the Power button again to turn the monitor back on. This should unlock your OSD menu and remove that message from your screen. best regards
