Instead of raising brightness for day viewing, raise gamma one click. Will make a big difference. Then lower it back for night viewing. CNET backlight is way too high. I have my 735 set at -4 for both day and night, and raise gamma instead for day viewing. At night gamma is set at 0 and during day +1. If a really bright room raise it to 2. Raising backlighting too much will expose clouding issues.
RIP Robin Williams. Thanks for the laughter.
