I bought a new LED Monitor Samsung LS22C350HS/XL few hours back. I came back home, removed old CRT monitor. Plugged in new LED and used HDMI cable with my graphics card Asus 6670 1GB DDR5.

Problem:-

Monitor going black and it comes back within 1 or 2 second. I noticed, Power light is on always. Its happening in 2 or 3 hours interval !! Please help me... Should I ask Samsung to replace or is it my own problem?

Resolution 1920x1080

Make sure your graphics card drivers are all the way updated. 90% of the time this is the problem.

That's kind of an odd problem. Maybe I would try a different socket for the wall?

ok... a technican from Samsung came. He told me to change HDMI cable. He says "if u r running ur monitor through HDMI cable and if u see...screen is going black and comes back again, then it must have to be HDMI cable's problem."

So, I bought a costly branded HDMI cable. Problem is gone now. I hope this information will help others if anyone face such problem.
