Try bypassing the Onkyo and plugging straight into the tv with hdmi. Try these and see what happens.
Fellow AVS readers....IMO, proper picture settings significantly help with flash lighting and bleed issues. I noticed that when my blacks were adjusted too dark, and the brightness was too high, the uniformity issues were very apparent. Once I got things dialed in to where I wasn't crushing the blacks and brightness was set correctly, the uniformity got much better. I agree 100% that these issues are a flaw of the ultra thin tv design that manufacturers are pushing nowadays. I have tried 4 different LGs this year (2-6700s and 2-7600s). All had uniformity issues due to design. Out of the box, all were bad. Once they were adjusted properly, all but one was a keeper as far as picture quality. (Had other issues warranting return...some was my stupidity). My 2 cents. If anyone is having issues, try the WOW disc or free AVS calibration disc (free) and see what happens.
The line at the top isn't a real line, it is like a shade of light that is lighter than the rest of the TV, but it's not like clouding/flashlighting because it looks symmetrical going from left to right across the top of the screen, whereas I've never seen flashlighting look symmetrical. Really hard to explain. Changing the aspect ratio didn't get rid of it, it's not just on Uverse, it's on everything.
Do you use the same contrast & brightness for daytime and night viewing, or do you change that too when you change the backlight? (And if so, to what?)
Also, does anyone use Dynamic Contrast? I feel like it improves PQ, even details in shadows, but I see it off on everyone's calibrated settings.
Last time I posted I was thinking about trying plasma, since ppl praise their PQ, but after reading the Owners Threads for the VT50, GT50, and ST50, it sounds like more work than I can manage right now to prevent IR. I don't want to have to 'baby' my TV, so I think I'm going to exchange mine for another 7600 before I try something too crazy. Just hope the new one will not look like it is playing Hulu or Apple store shows in slow motion.
