Well, I stumbled across this thread today and just went and took a look at a 57731 at the local Fry's to see for myself. I'll also give a little insight for those thinking about Sony or Samsung as well.
- I had a 50" Sony SXRD for about 2 weeks. I returned it...green blob syndrome. Right in the center of the screen and in one corner it had a green blob that was most noticeable on light backgrounds. It was easy to see because hockey season was going. Granted, it got lighter as the lamp warmed up and I could've lived with it, but not for how much it sold for. I even got a great deal on it, being in the military. A lot of these TVs have the problem, so beware. The picture was great, but not that much better than any new DLP. I guess it would be the best option for those that see RBE.
- Prior to that I had a Mitsubishi 52627 for a little less than a month. The picture was good, comparable to the Sony even. I traded it in because I was offered such a great deal on the Sony (and went with the rave reviews...mistake). I also didn't like setting up the TV...it was a pain in the ass and actually reset on me for no reason once making me take an hour to set everything back up again. The fan was also loud and could be heard during quiet portions of programs or movies. It did give me a good impression of Mitsubishi though.
- I currently have a Samsung HLS-5688. Great TV but I agree with some of the comments on here. Don't expect a great picture right out of the box. I had to play with the settings quite a bit but it wasn't too difficult. Now it has a good picture, although source of content is always an issue, as it will be with any TV. I was originally going to get the 5679 (LED TV) but it got delayed too long and it was getting to be like computers. If you keep waiting for the next best thing to come out...you'll never get anything...haha. For now, I'm sticking with the Samsung.
Now to my experience at Fry's. Lined up were a 60" Sony SXRD, JVC DILA, Mitsubishi 52628, Mitsubishi 57731, and Samsung HL-S5686W. All were using the Mitsubishi HD feed (1080i) All screens exhibited a little of the sparkle effect. That is because they coat them for anti-glare on the outside and the inside receives a reflective coat to brighten the picture projected on the screen. It is the little dimple pattern you see if you look closely, and becomes visible especially on light backgrounds. Some Samsungs seemed to have received a little too much apparently. Mine doesn't exhibit any more than any other manufacturer's, so there isn't much I can do. Even the new Mitsubishi had it. Side by side the Samsung actually looked better than the Mitsubishi, and that is the low-end 86 model. The Sony looked the best, but then I immediately think about green blob and I'm turned off...haha. I actually like the cabinet on my 5688 better than the Mitsu in that I don't use the speakers and the Samsung has the nice hidden speaker design. The Mitsu also seemed to have more depth. I'll agree with the people on here waiting for the 732...if it comes in black it will look nicer. The gray to me just looked kind of cheap. If I hadn't walked up to it I would've thought it was some cheap brand. The overall design is nice though, and I like it better than last year's model, like the 52627 I used to own.
While all the pictures looked good I think the Sony looked best, followed by the Samsung. The JVC and two Mitsubishis were next. I don't think you can go wrong with the Mitsubishi but in the end it is what you are happy with. Don't rely solely on someone's opinion on here. Don't even rely on my observations, for that matter. Use them as reference but choose what looks best to you and is what will make you happy. As you'll see in just about any thread on here, however, feeds in stores aren't that great. Similarly, everyone's house is different, along with lighting conditions and what not. Only the TV sitting in your living room will show you if it's good or not.
