Long post, but these are my experiences after 3 hours on day 1 of having the tv.
TV Arrived yesterday (xbr65x850c)! Amazon's white glove delivery service actually did all of the unpacking and stand installation, and powered on to check the screen.
I seem to have lucked out (mostly) as far as picture quality. The only vertical bars I see are on solid black backgrounds (I ran color breakin slides for a bit to see what they would tell me). They're super thin, and probably follow the backlight array. It's not really noticable. The only visual issue I have found has been a tiny bit of flashlight effect in the lower right corner, and again it is only visible on solid black backgrounds. I'll try rubbing it out to see if it goes away. I just don't want to see it get worse.
The remotes feel incredibly crappy in construction, but they do seem to work pretty well. They were almost immediately replaced by my harmony elite. They'll be retired to my "drawer full o remotes" once I have everything working as I like.
Overall, my experience was excellent with the setup. I created a new gmail account for my wife and I to use (so our personal gmails weren't tied to the tv, because that just felt weird to me in a house with multiple people). Now I have to go through and favorite all of my favorite youtube channels there, and she can add hers.
During the initial setup, it prompted me if I wanted to run updates, so I did. Now I'm a bit concerned I shouldn't have done that, because I'm seeing reports that there are different types of update, and doing them in the wrong order can break things. I'll see what happens tonight.
Viewing angle is about what I expected, but sadly it does get a little washed out on the edges if you go more than 15 degrees (i'm guessing) away from directly in front of the TV. On our sectional couch, that's a little annoying because the side bench and chaise both fall at about that angle, so viewing just isn't as great there. It was enough that my wife commented that things looked washed out and blurry when she was sitting next to me on the side. Some of this did go away once we took away the brightness control. Actually, graphics quality seemed kind of dull and muddy off the bat, but turning off automatic backlite control seemed to help a lot with that. We're coming from a 1080p samsung plasma where the viewing angle was essentially anywhere in the room.
I find it interesting that every HDMI port defaults to "game". The colors on this setting are kind of dull and muted. At first I was worried, but if I hit the "football" button, everything looks beautiful and bright and vibrant, so I know the tv is capable of making things look awesome. I think I just need to find a set of configs that works well for our den instead of the defaults.
I was also surprised that there wasn't a "PC" mode for HDMI-DVI input. Luckily it seemed to realize that a PC was connected as I didn't have to do any scaling or overscan tweaks.
I played a SBS film, and after some fumbling I found the 3d field in the activity menu. Sadly, i tried pairing my samsung ssg-4100GB active 3d glasses
, but they will not pair. Holding them right in front of the tv and pressing the sync button, they flash green, and then red. No matter what, I can't seem to get them to sync. I'll keep trying because I don't wanna drop 40$ on another 2 pair if I don't have to.
The upscaling looks really great on most of the test videos I tried, EXCEPT
(I have a full res version I use for testing). Once you get about 3/4ths of the way into the video, the birds that were still clear on my 1080p plasma are now tiny little white blocks. This isn't a huge thing, just something I took notice of. I sit about 11 feet from my TV, so at that distance I can't really tell the difference between a bird and a white block anyway.
Things I'm going to do tonight:
1) Sideload es file explorer, xfinity tv go, and udemy
2) Start playing with display configs to try and brighten up colors a bit
3) Try pairing my bluetooth keyboard/trackpad (not a huge deal, but it will probably be required for udemy and xfinity)
4) Disable some of the extra UI elements that I won't use
5) Set up bravia sync for my ps3 and ps4. It will be really nice not to see a "please turn on your playstation" message on my harmony elite when I run a playstation activity if it works like I hope it will.
Overall, my impressions after a mere 3 hours are pretty good. I know there is a lot to learn still, so I don't wanna judge too harshly. I also think I will need to dive into that FAQ a bit more.
