Windows 7: Second monitor black screen, worked earlier

Second monitor black screen, worked earlier

Hello,

My second monitor is a VGA monitor and worked for several months. Now i moved my computer setup to another room, and i can't get a picture on the VGA monitor. It's on and detected but it's just black.

Everything is connected exactly the same as previous.

When i boot my computer i can see the boot menu flash by for a split second, and when i change the resolution i can see the windows background for a split second. (literally 0.1 seconds).

I already bought a new dvi-vga adapter because some pins were damaged, but it didn't fix the problem.

I have the latest drivers. Already tried uninstalling and re-installing gpu driver.

I can move my mouse to the right (extended desktop) so it definitely detects it.

I'm on Windows 7
i5 2400
radeon hd6850


Thanks

It would seem that you have damaged the connection in some way. You mention bent pins in one of the connectors. It's possible that you have damaged the socket on the GPU. Have close look at it & see if there is any damage.

Have you tried changing the lead to the monitor.

What exactly is the 'lead' ?

I have plugged my main monitor in that same socket and it worked fine so i don't think its the socket.

It's so weird i see the screen give image for a split second when i change the resolution.

The lead in this case is the wire that goes from the GPU to the monitor.

I don't have a spare one right now. Would have to buy a new one first.

Take the old one with you so you are sure of getting a matching one.
