    Dual screen issue, 2nd screen turns black ...


    finaly at home again, sorry for the wait guys.

    yes it is a desktop pc. i did swap the cables around and the problem didnt move to the other monitor instead it more or less stayed at the "troublechild" monitor. The monitor didnt give me a picture at all anymore. When i switched back the cables, it instantly showed a picture and also stayed on. *sarc

    no i dont use hdmi on that monitor since i would have to buy a adapter for it and there is also no cable box, my tv is directly connected to my computer via hdmi.

    I will have a look into it but my solder skills are rusty and i dont have the tools for it.

    sorry for the dumb question, what kind of picture? the background picture? and how is the back light connected to my issue?

    again thanks for all the help and suggestions.

  2. LCD monitors need light shining from behind (backlight) to be visible. If the backlight quits, the screen goes dark. The image is still there, you just can't see it. Shinning a flashlight from in front may show you the image. If you see it, or part of it with the flashlight you know the display part is still working, it's just the backlight that quit. If it's completely dark with no discernable image, its likely more than just the backlight that's failed.

    Open a light picture with a lot of contrast. I don't see anywhere if you tried duplicate mode so both screens show same thing.

  9. Replace the monitor. I can't say for 100% sure, but it sounds like a failing monitor to me.
