T40 owners - LCD takes time to warm up?

[stateofbeasley]

i got a 2373-19U T40, and it works great. i notice though that the screen is kinda dim in the bottom corners when I turn it on, but that it seems to "warm up" after a bit. Is this normal? T40 owners help me out here

i have T40, but i dont think i ever see dim on a certain section, you might want to get it check out, it's a bit odd.
