I received my 5080 yesterday and it seems that the option to have the 4:3 side masks display a black and white soft-focused copy of the signal is gone.
D-Nice, could please confirm that that's the case? It's very unfortunate because I really loved that option when I saw it in the stores on the previous version. I wouldn't understand the reason to drop it.
I also noticed a problem with the 4:3 detection: apparently the detection doesn't work once coming out of the OSTG screen. Basically, if I set the option to apply the widezoom aspect ratio when side bars are detected, it works when browsing channels, but not when opening and then closing the OSTG.
Overall I'm very satisfied with the picture quality. I didn't have any doubt on the quality of the panel itself, after all the consistent positive feedback from professionals that had the chance to see it. I don't have a previous plasma set to compare it to, for the record.
Oh, and yes, there is some buzzing, but it doesn't seem too distracting. Changing the power settings to "mode 2" noticeably decreases it.
If I want to be picky, there are one thing that somewhat bugs me, but it's just because I'm very picky: why does the internal tuner shows so many digits for the channel (for example, instead of 2.1, it shows 00002.001)? I know it was the same with the past generation, and probably with other brands as well.
