EDIT: Pictures of problem located a few posts down. Hey, I'm concerned about this problem that has recently cropped up. I'm running a 40 inch SAMSUNG monitor and a 15 inch MBP. Now, recently I noticed that the color on my MBP just suddenly and randomly dimmed down... colors that were more vibrant and slightly less so, and seem more de-saturated. Anyways, I hooked up the MBP to my TV and I noticed that suddenly the color dimming leapt from my MBP and onto my Samsung. The weirdest thing is that if I slowly drag a window from my MBP (which is now, for whatever reason, displaying its normal and vibrant colors/brightness) onto my TV, I can see that the colors remain bright and vibrant until I drag it further in the screen and then there's this sudden dimness. So, when I peek a Safari window or a picture at the edge of the screen, it stays vibrant on the TV, but then when I drag it entirely into the middle, the monitor seems to readjust and dims down the color. What's going on here?
