I have a Dell laptop with a docking station and two external monitors hooked up. I'm running Windows 7 64 bit.

Originally, the two monitors were the same - Dell 1908FP. I have replaced one of them with an HP LA2405. I have set the HP 24" (1920 x 1200 connected via DVI port) as montior 1 and extended to use the Dell 19" (12080 x 1024 connected via VGA port) as monitor 2.

I have set my power plan so that when the laptop is plugged in, it will turn the monitors off after 10 minutes, but it will not put my laptop to sleep.

However, now that I have the HP monitor, when I unlock my laptop and the monitors come back on, all my windows are resized and shifted to the top left corner of the HP monitor as if they had been resized for display on the smaller Dell monitor.

A co-worker has the exact same laptop and monitor configuration but doesn't experience this issue, so I figure there's some configuration that's different but we can't find it.

I haven't been able to find any mention of a similar problem doing an internet search, but I'm not really sure what terms to use in my search.

Anybody have any suggestions as to what may be causing the issue? OS setting? Monitor setting?

EDIT:

My laptop is using the Intel Graphics and Media Control Panel/drivers.
