Monitor flashes several times after coming out of sleep mode

[KG2002]

Every time I wake up my Mac Pro, the monitor flashes 2-3 times before it is fully on. Quite annoying. Any idea what it might be?

I have the latest Mac Pro 2.66 Quad (got a referub about a month ago) and LaCie 526 (same as NEC 2690). Basic video card, DVI connection.

Would greatly appreciate your help.

My HP LP2475s (both connected over DVI to my stock Radeon 2600XT) flash a couple of times when waking up from standby, too. I passed it off as normal.

My Mac Pro and Dell 3007WFP-HC does the same. At first, I thought the monitor was going and got it replaced under warranty, but the replacement does the same so I figured it's normal...
