Here is my brief review of the 65" F8000 - UN65F8000
[Don't know why we have two separate threads on the F8000, but thought I would post here as well for those interested...]
I had 4 different UN65ES8000 sets delivered by Amazon over the last 4-5 months. All had stuck or dead pixels (or both) and the banding on all 4 sets was unacceptable (note: EVERY panel above 55"-60" regardless of manufacturer is going to have some vertical banding). All of those sets were returned. (Note: Amazon also initially did a horrible job of delivery with those sets sending a 1-man crew to deliver a set that requires 2 people to carry properly.) I just could not swallow spending $3500 on a set where the picture had so many issues.
Ordered the UN65F8000 from Amazon. Was delivered this week with a new delivery company (seems Amazon finally got the message). 2-person crew, very careful and nice.
The build quality on the 65" F8000 is far above that of the old ES series. It irked me that the ES series frame had metal edges that were just "bent" into place and didn't even join entirely at the corners. The back panel was also an eyesore. The overall fit and finish is not what you would have expected of a $3500 set. The F8000 improves on all of these points. There are no seams at the corners, there is a continuous metal band that wraps around the entire set. The bezel is small and unobtrusive - very sleek, very minimalist. The camera is no longer fixed at the top of the set and the Samsung logo at the bottom of the bezel has been reduced significantly in size. Overall, the package is just about perfect. Without going to an edge-to-edge glass design, I really don't see how it could be improved upon. The old ES series you noticed the frame (as small as it was) - the new F8000 series you are challenged to even see the frame - it is that good.
I am not a huge user of the Samsung Apps, but the new layout is much better and mimics what you'd expect to see on a tablet or such. New quad-core processor does seem noticeably snappier in operation than the ES series.
In my humble opinion, big improvements here over the 65" ES series. Not perfect by any means, but significantly improved. First, I did a pixel test using R/G/B/White screens. Amazingly, I lucked out and had no stuck or dead pixels. I test by looking at the solid color screen from about 1 foot away (at normal viewing distances you'd be challenged to even see a single dead or stuck pixel). There is one pixel (not even sure it is an entire pixel) that at 1 foot away appears to have an issue, but only when viewed off-angle. If I look straight-on or back up slightly, you don't see it at all. Certainly can't see it from intermediate viewing distance or true viewing distance. Don't know what that is about or why it is only visible from off-angle (perhaps something to do with 3D?). Anyhow, from my very bad experience of going through 4 ES series sets, and each getting worse (or just a different type of bad), this looks like a definite keeper.
Did a vertical banding test using a solid 50% gray screen. You can definitely make out vertical banding on this test from a normal viewing distance, but it is significantly more subtle than the 65" ES series. The ES series banding was dark and stuck out like a sore thumb. Further, the ES banding that I encountered on all 4 of my sets was not even uniform making it stand out even more. The banding I see on the 65" F8000 is definitely there, but lighter and the bands are more uniform. I am seeing them down the center and about 1/3 the way out on each side of center. Since I have experience with 4 different ES8000 sets (all 65") I can definitely tell you that the vertical banding is still there, but has been improved. Note to the wise: If you test for it on a larger set 60" or above, you'll likely see it if you know what you are looking for. If you don't watch a lot of soccer (my favorite), hockey, or golf you likely won't have an issue with it. I would challenge most casual TV watchers of network and cable TV shows to even see it. Bottom line on the F8000 - vertical banding is still there, diminished and I think tolerable. I've watched some movies, TV, and a soccer match and it is better that the ES.
No real issues with flashlighting or any clouding that I can make out. Blacks look pretty darn good, though I have yet to watch anything like Batman on it yet.
The picture itself is very good. I think better than the ES series. Despite some other comments here, I think the picture "pops" just as much as the ES series did. Colors look really good, very vivid picture. I do have background in color sciences, though I never go as far as to professionally calibrate my TV (sure, I know I probably should). Bottom line: the picture looks great. You'll be thrilled watching any type of TV show or series, animated stuff looks unreal (The Lorax - thus why they play that at Best Buy - probably looks OK on any set), and sports look great with the exception of panning shots (esp. soccer, hockey, golf) where you will make out the banding. Note: On my old ES series sets that I returned, I watched a ton of soccer and eventually my perception of the banding went away over time. Not saying this will happen for everyone, but if you appreciate the overall picture quality and don't think about the banding, you'll see much less of it.
In my opinion, big improvement over last year's set and worth the pain I went through with my 4 returns to finally end up with the F8000. Most of us here are insane about our TVs. Reality is that there is no perfect TV. Edge lit LED-LCD sets like the 65" F8000 will all have some issues. I think the ones here are acceptable and overall this is a very good 65" set. To save yourself from going crazy, don't do a pixel test or banding test. Just watch it and see what you think. If you like what you see in your viewing conditions with your content, you have a keeper - and your sanity...
Another way to do this is to go buy a crappy LCD like I did as a stop-gap while I was TV-less waiting for the F8000. I picked up a Vizio 55". My wife who is as far from a videophile as one can be even commented how crappy the picture was on the Vizio. When the F8000 came this week and I returned the stop-gap Vizio, she said, "Oh boy, now I can really see the difference. Glad we have this TV."
Good luck all!
(PS - Any comments on what I may be seeing with that one weird pixel?)
