Screen color

Any idea why the left and right TZT2 screens have different blue hues?

Is the viewing angle setting the same on both units? If not, that would cause the difference shown in your photo

Exactly the same configurations....

Did you try going into the setup and changing the viewing angle of the washed out display? That screen looks exactly like what I see when going through the viewing angle options.

Otherwise I think you may want to try a "hard" factory reset before concluding it is a hardware problem.

Looks like viewing angle adjustment to me also, but could be brill or other settings also. Like Quitsa, I don't think that is an issue with the unit.
