What is the recommended color temp. setting for X1(Cool, Warm or Warmest?). I just upgraded to 4.3 firmware last night. I know the X1 previously had the 3 color temps labeled wrong in menu(according to Projectorcentral.com)but I don't know if the 4.3 firmware fixed the problem. I'm trying to calibrate it with the Sound and Vision disc, but it won't let me set the red, green and blue levels. Thanks.
