I've had my 735 for a few weeks now and thought I could give some prospective buyers (and users) another opinion to add to the pile.
First, I do care a bit about PQ as I'm sure anyone who visits this forum does. Let me state emphatically if you haven't already gleaned it from the earlier sixteen pages--the 735 is not by any stretch a perfect system. It is really a compromise between best possible at this size for this price. Having had it for a few weeks now I can say:
Definite minuses are:
--'dirty screen effect' DSE is noticeable. I've noticed it more over time--one of those things you can't unsee once you see it. An usually during pans with solid background.
--does have some clouds which are visible when the screen is solid dark. Practically unnoticeable if there is any activity going on on the screen even in dark shots.
--doesn't seem to handle gradients of darkness very well. Dark areas can be banded or show pixelation a bit. This varies per source.
--Dark corners. Smaller and less pronounced than I thought they would be after reading this forum before my purchase. Yes when you have a solid bright or white screen if you look you can see a bit of darkness in the corners. Honestly the screen is so huge and the darkness is so gradual in the corners that your eyes are stressed to comprehend the whole of the screen and tend to be focused on the center. Doesn't take away anything really. Has never been an issue during any movie, tv, or video game.
--General Picture Quality. When viewing TV shows, Movies etc. The picture just pops, the colors are bright, the details come through amazing and clear. There's definitely a 'wow' factor. The amount of different presets they give you: standard, movie, game, user, dynamic etc. are impressive and make it easy and quick to match to what you are watching. I've tried a couple of the detail settings posted on the forum here in 'movie' mode but didn't like them at all. The standard mode just looked better than the tweaked-out movie mode which looked too yellow-y and muted.
--3D. 3D just works! I've been able to watch 3D movies both animated 'Coraline, Tangled' and live 'Avatar, Imax sea' etc. and the 3D is outstanding. Ghosting varies depending on the source and in some cases the scene angle, etc. I've got the point where I can note the difference in quality when the 3D was formatted for 3D SBS fairly early in a program. The 2D to 3D conversion actually works pretty well too. Not anywhere near as good as real 3D, but I had fun playing 3D Skyrim etc. on Xbox. Active glasses will give you a headache after a bit tho. The 3D glasses' (An-3dg20) functionality to swtich to 2D while in 3D mode is very useful and has been used by everyone in the family at least once at one time or another. A nice feature this TV has is it pings you every hour you've been running continuous 3D.
Ironically I've never actually used a 3D Blueray yet on this TV. For those of you who are interested, I've worked out how to stream 3D MKV (SBS) files from my PC (on TVersity) wirelessly in the next room to my TV via xbox (connected via component video cables!) and MP4 (SBS) files through iTunes/Apple TV via HDMI. I just have to click 3D on the remote and tell the TV to go to SBS.
So in the end I was torn. Cool picture and 3D, but with some noticeable trade offs. I got the TV for a shade less than $3k but I had to do a bit of driving to do it. Now that I'm past the 'picking apart the defects' phase I'll probably settle in and keep the TV, accept its limitations, because I'm pretty happy on the whole.
