Hola, yo lo tengo desde hace un par de meses, y muy contento la verdad.

Yo puse una config que vi en avsforums, es esta.

Brightness: 8
(This is because I use full Range 0-255 Signal from my devices and the Optoma forgets after each restart to hold the setting 16-235 and starts always in Automatic color space, which is 0-255 - this seems to be a software bug).
Contrast: 0
Dynamic Black: Off (Please dont use dynamic black, because it does some very bad gamma shifting which can look very unnatural and ugly in specific scenes).
Brilliant Color: 1
Noise Reduction: 0
Sharpness: 7
Gamma: 2.6
Color Temp: Standard
Color settings White:
Red: 0
Green: -7
Blue: -5
The other colors in the color management I left at default, because they track very good OOTB.

Un saludo
