After fruitlessly persuading my company to buy an Apple 20-inch monitor instead of a Dell monitor for image analysis, the Dell monitor finally came. We hooked it with the computer, it showed image; I set the background to none, adjusted color setting to black, and turned off all the lights; Aha, the monitor has a dirty face: The backlight is not even at all!!! The upper-right corner has a smear of whitish background, a bulb seems sitting right behind the screen. The lower-left corner has the same issue, much brighter than the surrounding area. It's definitely ugly. I know Apple's 20-inch has no such an issue. That's typical Dell: cheaper price (S399 vs Apple's $799), usable monitor but genetically deficiency somehow. Apple's 23-inch has similar problem. Has anybody checked Dell's monitor the way I did?
