if you put up a red green or blue 24bit color gradient on the screen it has banding issues, notably one large band before black that would turn almost black and then get lighter till it smoothed into black like it should.
I was able to tune the bands out of each of the primary colors by using this pattern and the colormaster function in the TV menus to adjust each of the colors independently, interestingly enough the area below that color band would never change when i adjusted the color settings for each color all changes stopped at the bad black band in the middle of the gradient.
the good news is its fixable i suppose but without having a color meter to do a real calibration i have no idea how close or far it was from being calibrated at those single settings that removed the problem.
The TV's motion enhancer works ok but produces a lot of artifacting compared to other better brands like sony and samsung
the last issue i had with it that really bothered me at night was the extremely purple tinged blacks at pretty much any viewing angle except dead on straight in the middle, it was very annoying. the black uniformity was also pretty poor out of the box but i was able to reduce the flashlights by loosening the cabinet screws in the corners of the TV
overall it was a decent TV for the money but for our use of a TV in the living room sitting 10' away we returned it and bought a Panny 50" X1 720p plasma and its many times better than the Toshiba was and cost the same amount of money. don't even miss 1080p at our viewing distance either because the 40" was too small to see the extra detail at 10' and the 50" 720p easily shows more detail due to its size at 10' away even though its only a 720p display
