I used to have a Toshiba TN61x81. I've got to say that the default color scheme on it was far superior to this new Mitsu 60738. In fact, I've gotta say, that the default settings on this tv are piss-poor. That being said, if you adjust the settings, you can get it to look pretty darn nice.
Basically, my biggest complaint is the tint. I'm used to not having to adjust that setting. Here are my settings:
Picture Mode: Bright
Color Temperature: High
Video Noise: Medium (or Low)
Deepfield Imager: On
It's hard to get the color right, when the tint is so far off. Now, this picture is pretty darn nice.
Picture Mode: Brilliant - I like it, just to have to lower the color to compensate. By default, Brilliant and Bright are waaaayyy toooo green. I prefer them to natural and advanced.
Natural: Color Temperature is low by default. White is red. Luckily, you can adjust this.
Advanced: Color Temperature is low. You can't adjust it. This mode sucks. With even tint, I was trying to adjust the colors, to normalize this. 1000 blue, 800 red, 600 green. I think it would have looked nice, if it weren't for the low color temperature, where white is red. I would try again, now that I've got the tint right, but I see no point, as I can't fix the Color Temp.
Now that this tv is adjusted, I love it.
