I have viewsonic pf790 and this monitor behaves strangely lately. If i turn a monitor first, i normally receive "no syn" error message. Lately, i don't receive this error message any when i turn my monitor FIRST more and when i turn my computer on, nothing shows up on the screen.
it only happens randomly and i don't know what goes wrong.??? I mean sometimes i see "no syn" and everything is FINE and another time is NOT ok.
if you have any suggestion, please let me know. Thank you.
