GTX 275 and samsung monitor not working corectly

[zedtek]

Hi, i recently just purchased a new system

i7
p6t se board
6gb ram
gtx 275

now the problem is some times the monitor would appear in sleep mode and nothing comes up, just a black screen. Ive relised that if i unplug the monitor from the dvi connecter and put it back in the picture appears.

Now do you think this is a monitor issue or video card problem? ive been running the old monitor with my old system flawlessly, if it is a video card problem i would like to return it.

If you installed a new OS then you probably have the "turn off monitor" screensaver selected.
