BenQ LCD intermitent signal loss at boot up.
Posted on 2004-10-21
I'll try and explain this as best as I can.
I have a BenQ LCD FP 2091 monitor. I use the DVI output. It is connected to a Radeon Saphire 9600 Atlantis. I've gone through numerous vid card updates and it never changed, so I ruled out the video card doing this and my last crt monitor was fine.
1- If I open the monitor before I boot the PC , the light on the benq will go green and then it will say no signal found, my screen then stay black but the light is still green. Sometimes it does come up fine but it is a rare occurence.
2- If I boot the PC and wait until I hear the cmos beep and turn on the monitor right after, I'll usually get the green light, it says no signal found but then quickly finds it and I'm ok. Very rarely this will not work and I have to try again until it does.
3- If I boot up and open the monitor later, say 10 minutes, the light will go green and it will say no signal and stay green, while my screen is black.
Lastly, when the light stays green and the screen black, none of the buttons ON the monitor will function, I can't even turn it off!
I just connect at standard 15 pin connector and this does the same thing.
Does anyone have a clue what could be wrong here?
