Just received my 60GT50 yesterday. Am very pleased so far. I watched some ESPN, and I can say uniformity is not perfect, and there are slight issues with what I'm going to define as crosstalk when you get too much motion. Still, it's only noticeable when you're watching the areas of the screen where compression shows up; things like black booths or chairs as they're in motion. It's fine. The set is very, very good. I did have IR, which surprised me because I ordered a used tv from amazon... Checked the hours (thanks to everyone who posted little helpful guides on that and other things), seems amazon sent me a brand new one. I ran slides for 2 hours, IR went away. I've now been running slides all night, and will be running them with some breaks inbetween till I'm around 150 hours. I imagine that should give the phosphors a chance to age well.
Color depth and accuracy is very good from what I can tel so far. The set never has to try too hard to get them up to par. I wish it could be brighter, but the thx bright room setting is very good out of the box. I don't think you'd even want a calibrated setting if you're going to be having lots of light and glare; it's great as is. Obviously once I get the set burnt in a bit, I'll be trying various settings like hdmaster's and we'll see how well it can perform at night.
About the buzzing? I haven't listened for it, but I haven't noticed it at all even walking right past it running slides. I guess I got one of the good ones, and I wouldn't be surprised to hear that there are alot of good ones. It may buzz, but if I can't hear it walking past it, even with a pure white slide on, it will not be hearable from any sort of viewing range. By the way, 60 inches is fing huge. It's really, just completely, too big for the room I've got it in. But who cares. I am the man in this house dammit, and my TV stays!
The one disappointment is the usb compatability. Still, that's the kind of thing that could one day be fixed with updates. I'm really interested to find some larger forum like an official panasonic forum, and seeing if some enterprising person has hacked the firmware enough to be able to add in new codecs. My problem is that it will play most of the video codecs, but very few of the audio ones. Still, a few files did work, and that makes me hopeful. The last thing I want to do is run some sort of dlna with transcoding. I've tried tversity, and it's just terrible. A perfect source looks horrible on your tv, especially a tv this big, no matter the transcoding settings. Will try serviio as someone mentioned above, thanks for that.
Other than that, great tv. If you're still wanting a tv, get this one. Or wait till the 13 tvs release, and these should become very affordable. Make sure you get decent speakers too, by the way. These speakers could be worse, yes, but they're slightly better than bad. Grab a cheap receiver, some cheap wire from home depot/lowes, and spend some money on a pair of good floorstanders. It kills me to hear of people watching movies on these great big 65" tvs, and listening to the included speakers. You're missing out on half the experience! The experience is the movie, not the tv!
Anyways, thanks guys! I always drop in here to figure out what to buy when it comes to tvs and speaker. Now I just want the money to get speakers that can get close to replicating the sound from my Grados, and I'll be just fine.... Again, thanks for all the help.
