  1. Hi all for a while now I been plugging external monitor into my laptop as I do karaoke some times always been fine but now all of a sudden when I plug it in the screen on monitor goes red & blue . tried 4 different monitors and all do the same so was thinking is it a simple driver issue or has something come loose inside on the vga port.. went to a shop and they wanted £90 no wayyyy . all help or suggestions will be greatly appreciated .. thanks

    Are you using the same cable when you tested w/ 4 monitors? Something similar happened to me a while back and it was due to a bent pin. I was able to straighten it and fixed the problem.

    Hmmm...maybe something, a connection, got loose over time as you connect/disconnect. Perhaps a solder joint needs to be repaired. This is a VGA connection on the mobo?

    I missed the part about laptop. Does it have a HDMI/DVI connection you can use? If not, there are USB to DVI or VGA adapters that will allow monitors to be connected to a laptop via USB. Not sure how well those work though. Hopefully, someone can offer some troubleshooting advices.
