So after 3 different a850's (and 2 different panels on the first one) I finally was able to just switch to a different model of TV in the Samsung line and wound up with the b750. My initial impressions are that this one is better than the a850 in picture quality, but probably not in the looks department. Not that it's an eyesore or anything... it actually looks quite nice, but it is thicker than the 850 by a couple of inches and I personally like the touch of red better than the gray. But that's just a personal opinion, and not one that's going to ruin it for me. It still looks like a really nice quality TV and people that have come to see it really love the way it looks. So here's my rundown for a couple of the items that most people seem to be worried about when looking for a set:
Picture Quality: When I first got this I selected "for home use" and let it set itself up. I turned on ESPN HD and then popped in the Wall-E blue ray. It's my opinion that the b750 has a better picture than the 850, and that's just using it's standard settings! I did a quick run through with some calibration test screens, but I think I like the standard default "home" settings best. I'll keep fooling around with it as the weeks pass. But if you're coming from an 850 and are hesitant to go with the b750, you have NOTHING to worry about. This TV is definitely at least equal (and in my opinion better) than the 850 in PQ.
Blacks: The blacks are deep and rich. I will say that it takes a little bit of adjusting so that you don't lose some of the details (as seen in some of the pictures in some previous posts), but it can be done. It's not washed out in the least and is on par with if not better than the 850.
AMP: The amp seems to work quite well. I don't see the soap opera effect that I noticed with the 850. I've tried it on most all of the settings, and they all seem to work well enough. I've kept it on clear most of the time though and it seems to do just fine.
Speakers: Not too bad. But if you care that much in the first place then you're probably going to have externals anyway, so it's kind of a moot point.
Clouding/Flashlighting: FINALLY NO CLOUDING OR FLASHLIGHTING!!!! The 850, as most are aware, had a horrible time with the clouding and flashlighting. I went through 3 of them before trying the b750. I was almost certain that I was going to see something on this TV too (just because I was giving up hope in technology), but I'll be darned if there wasn't a speck of anything! I made sure I looked hard too. I stared at a black screen from different signals in the middle of the night with all lights in the house off and couldn't come up with anything. FREEDOM!!!
Internet features: I haven't been able to figure out the networking to where I can stream video/music from my computer, but maybe one of these days I'll figure it out. The Yahoo widgets are okay. There is a delay between remote input and the action on the screen which can be cumbersome. And personalizing the widgets can be a bit of a mystery. But the widgets in general aren't really my thing anyway so there's not much more I can say about them. I won't be using them too much.
Gaming: I haven't had the chance to do any games, but I have a feeling that it performs well.
Screen reflections: Ours is set up with a northerly window to the right of it and no window directly across so there's not too much direct sunlight that hits it. So, naturally, there's not a whole lot of reflection, if any really.
Options: The options seem to be the same as the 850. There may be one or two things that are not included, but nothing that is going to hamper it in any way. Plus it has the added adjustment to the AMP that everyone's been talking about, so that's nice too. It has PLENTY of options to satisfy even the most hardcore video nerds.
Dimensions: This one is definitely thicker than the a850, but not a monster by any means. It's just over 3" thick. The bezel does seem to be thicker too making it seem bulkier than the a850. Hanging on the wall, it may not look as slick, but sitting on a stand it's just fine.
Off angle viewing: Like most all LDC's this one is no different with the off angle viewing. It does wash out some once you get far enough to the side by 60 degrees or so. I don't really care, but some people do.
Interference: This TV has no where NEAR the problem that the 850 had! I haven't noticed it at all really, but if there is any problem, it's minimal.
The only weird thing that I have noticed so far is that when you're on an HD channel (like ESPN HD) and they put the side bars on to a standard def. clip, the scrolling words at the bottom get choppy and stutter. This stops as soon as they take the bars away and go to a pure HD signal. Don't know what that's about, but I don't really care because it doesn't really bother me.
So far, I've gotta say, I'm 100 times happier with the b750 over the a850. The picture quality is every bit as good or even better than the 850, and the clouds that I was beginning to think was a part of my life for evermore are a thing of the past now. If you're on the fence about this one, I would just jump right off into the b750's corner.
If I've missed anything, or if anyone wants me to explore something else on the TV, let me know and I'll see what I can do!
