LCD woes: NewEgg said they would take it right back. Yay!
I called Princeton Graphics and they claim that the monitor I got was defective. They claim that the brightness issues are a defect and that one dead pixel is also defective.
The rainbow ghosting however I’ve learned is not a defect, it’s an artifact of 16ms LCDs. According to Tom’s Hardware 16ms LCDs don’t actually display 16 million colors, they only display about 220,000 and use dithering to flicker back and forth to give the illusion of 16 million colors. My guess is that when you drag a checkboard image around the screen the rainbow ghosting appears because the colors in the checkerboard are not native colors of the display and the monitor is slow to switch to the dithered colors.
