My Computer wont display the color red at all. Instead, it displays black. Then the rest of the colors are tinted mostly Yellow (Just take red out of all the colors and that what you get). It was fine one day, the i came home from school and bam, it was messed. Thing was too, I had jsut bought this monitor recently (like a month before). The odd this is, when the monitor is unplugged, it shows a NO SIGNAL screen, with 'No Signal' in a box, and the box has three small color bars in it, and one of them is RED! So.. it shows the color red and the rest of the colors fine in the No signal box, but when tis plugged into my PC, it doesn't work, it displays like the red in my monitor is shot. I plugged another monitor into my PC and it shows all the right colors, so it has to be the monitor. Also, I got the monitor with the same PC I am using now. Im using my old monitor from my old pc, and the colors are dislaying right. It jsut seems to be my new monitor thats not working. My monitor is a Samsung SyncMaster 955df 19'' Flat screen. Please help :)

Your monitor cable is no good. Happened to me 4 years ago with a nice Dell monitor...

Yup! It most likely is a broken (pin #1) wire in the connector on the video card. Wiggle it a little and you might see it work intermittently. Moving the monitor around a lot causes this problem. It flexes the cable and eventually the wire breaks.
