dell lcd flickering, please help

[abs9986]

I recently purchased a used dell 2007wfp lcd from ebay. I've checked the amount of used time by holding the menu button while turning it off. It has 1540 hours of use; ac power is 50 and soft key on is set to 55. It seems to be in very good condition...I bought it from Tigerdirect ebay outlet store.

Anyways, anytime I turn on the monitor or it wakes up from sleep/powersave mode...it flickers for about 10seconds...especially noticable on the whites. It then goes away and is not a problem. I notice that if the monitor has been on for a while and just goes to sleep....I can awaken it with no problem, but if it has been off for a while....that is when I get the flickers as if the entire screen is shaking. I have a atix300se video card with the newest catelyst 8.4 drivers.

my previous lcd was a 17 inch dell which did not have this flicker problem. I think this would rule out the video card. Both lcds are using the dvi (white) input

What do you guys think seems to be the problem?

Thanks,

Sounds like the backlight is acting funny, maybe getting old. Do you have to turn up the brightness alot to get good color? That's a dead give away of a failing backlight.

I am currently at 50% brightness which seems to be fine. Hours of use are also low at 1540. I emailed the user from the Tiger direct store...he said to me that several work stations driving high resolution monitors had this issue and that it was normal.
What do you think?

Not normal.
