HI, I GOT RELISYS 17 INC TFT LCD FOR ABOUT 16 MONTHS NOW FROM LAST FEW DAYS WHEN ITURN IT ON IN THE MIDDLE OF SCREEN A WARNING SIGN COMES ON SAYING INPUT SIGNAL OUT OF RANGE ANY SOLUTION FOR THIS?
Some how your screen resolution has changed above or below what your monitor can display. you need to boot your computer using another monitor that can work with the resolution your computer has switched to(i used a spare crt monitor when it happened to me) change your resolution in display properties to a normal level like 1027x768, and while the computer is on swap the monitor cables to verify the lcd is working.
It is perfectly safe to unplug the video cable and plug it back in while the computer is turnned on.
