I've had this issue off an on for a little while. The monitor is absolutely perfect, except when it comes to displaying dark black areas on screen. Then I periodically get vertical thin blue lines only in the black areas. No other graphix on screen get corrupted at all.. just the dark black areas. Sometimes these thin blue lines are long, sometimes very short, sometimes completely absent. I notice it mostly in gaming, running through dark cooridors. I also see it at its worst when I'm first turning on the computer, the boot up screen is all black with text.. and there are always thin blue lines running top to bottom, about a half inch apart, all the way across the display. This is on a XP Pro box.. with an ATI Radeon x850 card..
I have a LCD flat monitor and it has a black vertical band on the right side of the screen about 2 inches wide, which hides some of the texts of the web sites. Unable to fix it with the monitor screen control, the problem is obviously nmore complex. Please help.

the inverter or the lcd bulb may be out. inverters are cheap, bulbs are not. is the screen dark like its off or glowing black? if its dark like the bulb is off, next, look closely and see if you can make out a faint image on the dark screen, if so, it is likely the inverter.
elainenemeth, Hi, Tell me more! How old is this LCD monitor? Is it out of warranty? Did the "SHUT-DOWN-IMMEDIATE" problem occur without warning? Did the BenQ display a "perfect" image the day before? Did you actually count----1001, 1002----1010 and then it shut down, after pushing the monitor on button. Did you do the "flashlight" test? With monitor connected to a "known-good", fully booted pc with Win Desktop displayed, TURN ON the monitor! Did it display the desktop for 1-2-10 seconds ? What did you see or not see when you pointed the flashlight at different angles about 1-2" inches from the now dark (black) screen? Get back to me with your results. I will offer the best advice possible to you as a consumer/user of LCD/FPD monitor. I'm louie12fix on fixya or lmistyrel @ aol.com Bye for now.
I have the same problem. It seems like a virus to me, but my anti-virus doesn't find anything. I went to the main menu on the moniter and changed the display time to five seconds and locked the OSD display. Now all the appears is a smaller box showing a lock which goes out in five seconds. It is still annoying, but less intrusive then before. Hopefully, some one will determine a permanent fix for this problem.
