View Full Version : sony bravia lcd jtech85 04-17-2009, 09:50 AM Question: on the Sony Bravia KDL-46XBR8 the user menu white balance adjustments work fine but are you able to adjust gamma level in the service menu? What are the codes for RGB levels or is it best to stay out of there and only adjust gain and offset in the user menu.

You should be able to get a nice calibration using the user menu and calman/etc. scooper750 04-21-2009, 12:30 PM I found the RGB cuts/gains in the User Menu to be quite a bit coarse. Would be better off tweaking those in the SM. No need for gamma adjustments. I was able to achieve a flat gamma at 2.2 without gamma controls. |
