Hi everyone,
I'm probally not computer savy enough or know a lot about the workings of computers to be on this website, but I cannot find anything online that seems to be able to help me, We have Windows 7 and have been using 2 monitors for quite a while. I bought a new monitor today to suit our computer with the HDMI cable and set it up in the middle of the other 2. It is working fine and the monitor with the blue adaptor is also working fine. But the monitor with the white adaptor has a floating sign across it saying to 'check signal cable' I have pull the cable off and re fitted it, turn the monitor off and restarted it, but nothing has still happened. I am hoping that someone out there can give me some ideas on how to fix this in terms that I can understand.

Kind Regards



Can you post you computer specs?
your graphics card may not support another monitor.

HP p6340a
INtel Core(TM)2 Duo CPU E7500 @ 2.93GHz 2.94GHz
Memory 4.00GB

Do you have more detail on the graphics card you are using?
