I realize this is a long shot, but if anybody has any ideas or knows someone from Philips that could tell me something definitely on this question, I'd appreciate it. Here's the issue I have with this particular model(42PF7421D/37). I subscribe to AT&T U-Verse service. There is an issue on some model televisions where during the HDMI handshake between the STB and TV, the proper HDMI video settings are not negotiated. It seems as though the STB is defaulting to the 0-255 scale while the TV is defaulting to the 16-235 scale. This is causing issues with crushed blacks etc on this particular model. My question is this: is there anywhere in the service menu, etc. that I'm overlooking where this might be able to be set manually? Some other sets will offer a selection such as the following.
-Detect signal automatically
-Color-1: Set digital video signal format to component 4:2:2
-Color-2: Set digital video signal format to component 4:4:4
-Color-3: Set digital video signal format to RGB 16-235
-Color-4: Set digital video signal format to RGB 0-255
I'd like to be able to set the HDMI input to manually use option #4 that I listed above.
For the moment, I've resorted to component cables to get a proper calibaration. However, the component output from this STB is noticeably softer than HDMI for some reason. I may be forced to just live with one or the other if no fix for this is available, but I haven't decided which is more tolerable yet.
Thanks for any info you might have.
