Is SLI enabled?, try disabling it and tell us if it is still there.

new630i,

Does this happen also when you restart your computer or does it happen only when the system/monitor have been off for a while?  Have you tried the monitor in a different system? Have you tried a different monitor on the system?

SLI was enabled. I disabled it and restarted immediately with normal appearance of the screen but then turned off and waited 30-45 mins and when I restarted, the green pixels were back but only briefly (much quicker than before and did not seem as badbefore normal screen appearance obtained. I reenabled SLI and immediately restarted and got a normal screen appearance. I again turned the computer and screen off for 30-45 mins and when restarting the abnormal appearnce on the right half of the screen returned but again after a short wait, screen normalized.

 Once the screen looks normal and I do an immediate restart, screen remains normal. After extended period of time with computer and monitor off, the abnormal appearance returns and takes longer to correct. I am going to try and leave the monitor only off overnight but leave the computer on and see what happens.

I do have a second identical monitor and second DVI cable and will give that a try also tomorrow evening when I get home from work.

Thanks for your responses.

Dave

It sounds like either your GPUs or your Monitor has what we in spanish call a "cold welding"... an issue where something is badly welded, a component gone wrong or some other issue, that heating up will solve after a few minutes of use.

The problem with this type of situations is that they can get worst over time and the issue become permanent (or fixed all together! :(), so I think its urgent that you determine which of the components is having an issue and if you have warranty on it, use it.

Let us know,

Rafa.
