Backlight leak on Dell U2311
I just got a new Dell U2311 and plugged it into my mac via DVI-D
When the screensaver was triggered, I noticed a backlight leak on the top left and right side of the screen. There is a small leak on left bottom of the screen as well. Image attached.
Is this normal? Please advice !
(Default monitor settings are in place - I have not changed any setting via the menu)

kbvenu,
Is this normal?
Yes. Dell monitors do not have backlight 100% uniformity specification. As long as the center meets our manufacturer specifications, it is acceptable. Also, we do not validate our monitors in dark rooms. We use office environment lighting.
If the Brightness and Contrast are maxed to 100 and you measure the brightness difference of any two points on the monitor, the brightness difference will never be greater than 25%. Which is our manufacturer specification. Unfortunately, the human eye can easily detect any 5% or 10% difference in brightness.
