I don't mean to offend anyone who is having issues with their set. I am, like many others, very frustrated with the lack of communication from Samsung and lack of clear explanations of what exactly micro-dimming does, when it does it, why we can't disable the auto-dimming in standard (and movie also to a lesser degree), and so on. That being said, I wonder if at least some of the concern over picture quality changes with recent updates is simply due to power of suggestion and fears and distrust of Samsung and their mystery updates.
I updated my 7500 tonight and to be honest I see no difference in image quality. I will spend more time surfing through channels, but my first impression is that nothing has changed regarding image-quality. With so much concern lately with how Samsung handles their customers' frustrations, I wonder if at least some of the negative changes people are seeing may just be like a placebo effect, or power of suggestion (a person is so convinced that there will be negative changes after the update that they believe there is after they update). I don't mean to suggest that people aren't noticing differences, because the way Samsung handles these updates, none of us really know what is happening behind the scenes so to speak. But if an update is issued that affects image quality, we're all going to be affected, not just some of us. Either an update will cause "x" or "y" to happen, or it won't - It won't just affect some sets but not others. It doesn't work like that.
Anthony, I'm sorry to hear you having such frustration with Samsung. I was at boiling point last year, and early this year, before getting the 7500. They seem like they want to help over the phone, but seemingly know little to nothing about their own products, even with tier 2 or higher. Their email support is lousy - I've sent 2 letters to the office of president over the course of a few weeks, and I never got a response back from either one. I was really hoping we would actually hear some useful info on this micro-dimming. Until I know for a fact what this is supposed to be doing and how and under what conditions, I"m going to call it like I see it - voodoo. Sure, it seems to make some sort of difference, but nobody knows quite what is happening or why if it's so great we can't use it in movie mode.
I'm still frustrated by the awful clouding, especially the V-shape in the lower-center, which is by far the most noticeable. I asked a few pages ago but maybe it was overlooked - if all it takes is to dis-assemble the back and loosen some screws, why can't I request a tech come down and see the clouding, and when he arrives, just ask him to try loosening the screws and see if that helps iron it out? I do not want to risk voiding my warranty - so why can't I ask a tech to?
Also, I'd love to get Best Buy down here to tweak the color at the very least, but since I just read yesterday how a glitch doesn't allow correct calibration in more than 1 mode, I don't want to use up my free calibration until it is resolved with an update (if ever - how would we know when it is fixed, since they never tell us anything in the notes?).
On another topic, I was playing around with Samsung's 3D streaming clips, and there's some good stuff to see. I highly recommend "Battle of Grunwald" - it's a short 3D fly-through of the famous painting, fully translated into 3D - it's really quite stunning to be inside a painting.
For anyone looking for some really good 3D blu-rays - check out Lichtmond and Lichtmond 2 - I've never seen them in the stores so you'll have to get them through the 3D blu-ray rental service if they have them, or buy them online. It's just some colorful cgi fly-throughs of various fantasy worlds and landscapes, but the 3D is absolutely top-notch. Some of the clips have a very high contrast ratio so you do see some mild crosstalk at times, but the 3D practically wraps around you at times. Some of the best I've seen. Nice music too.
