i bought this samsum 39in led tv to use as a monitor - standard HDMI resolution.

I am running an Nvidia graphics card.

It works great, i wouldnt go back to a smaller montior.

the contrast is good, better then what i had with my "pc" monitor.

I can see allot better with the larger screen too for large assemblies.

I changed the Samsungs standard settings to better fit my preferences.

Problem:   It will turn off for no apperent reason or it will get weird lines all over the display from time to time

I have to turn it off and then back on for it to work proper agian.

I have to tru to turn it on a couple of times as it wont come back on right away.

Has anyone encountered this?

Is this normal?

thanks
