Finally received a replacement projector from Techtronics (my original 11HT went back due to a bright green stuck open pixel) ... so that's a good result for the campaign against dead pixels!!! Would appear that Sony are more inclined to replace projectors even with only 1 dead pixel if this is of the bright green open type? Anway I'm a happy bunny!!! I've been experimenting with hooking up my PC and have found that the 11HT seems to 'click' a number of times before displaying the PC display. This clicking can be between 2 and 50 clicks while it appears to be searching for the correct resolution/frequency etc ... is this normal???? Also, can anyone help with how I get my Radeon 8500DV to output the magic 1366x768 native resolution of the 11HT? I've read on a few threads about increasing black levels by adding a CC Filter? I was looking at the www.enhancedht.com ones ... anyone had any experience of these? Thanks all!!
