Hard to get 4K
Terrific picture. But at least for me, the 4K capability is useless for now. Netflix streaming in 4K via the ethernet cable connection results in frequent stoppage for buffering. (My download speed is 180M, but this TV only supports up to 100M. Don't know if that is the issue. It happens on multiple shows. Netflix itself may be the issue, but 4K just doesn't work). Amazon Prime video via ethernet doesn't work at all (it lets you get as far as choosing something to stream, but never plays it. This may be an Amazon issue.). So I watch everything via my cable box (Xfinity) which supports HD but not 4K. Netflix and Prime video work just fine there. I guess I'll have to wait for better cable TV equipment in order to get a 4K picture for more than 3 minutes at a time.

Needs a better UI access
This is an Isf and technicolor certified TV. However the user interface for adjustments has too many hoops to jump through to get to what you want to navigate on and adjust... I wish there were hot buttons for it. I also would like the ability to turn off color channels for calibrating and have ON BOARD test panels instead of having to put something on a flash drive.... It's actually pretty stupid that it's not already on there.
All of the proprietary names for functions that it has in the specs list for advertising it are printed as though the manufacturer assumes the customer knows what it is; but nowhere through the user guide that is on board is it ever mentioned again making you wonder if what you're looking at is actually the same TV that you wanted to buy. This is fine and dandy for a typical tech-savvy videophile that can figure it out for themselves but it's not a TV for the casual spectator with a lot of money. I'm done picking it apart for now as for the rest of it picture quality is what you can expect from LG; like I mentioned earlier it is ISF certified... Not really something that is necessary for Saturday morning cartoons and C-SPAN.

Get the 65"
I wish I had spent a few more dollars. The 55" isn't quite big enough. Perfect for standard blu-rays. DVDs look much more blurry.
Blacks are great. Noise in dark scenes but you can learn that if you use the right settings.
Speakers offer poor sound quality so you'll need speakers but most tv built in speakers are trash.
Smart features are flawless. Missing some less popular apps but more are being added every day.
Great tv. Had to refresh the screen about 5 times to get rid of some dead pixels when first gotit. Now it couldn't look better.
LG makes the best TV's. Other brands use their panels. Probably why they're so expensive. Look Kno further. This is the one.

Fantastic with a little room for improvement
I've had the tv for about a month and I love it so far. User interface is great, available settings for the user are abundant, and obviously picture quality is amazing. However, I have one request for the engineers working on the firmware updates. I have a retro console (Nintendo GameCube) and a upscaler device (mClassic) that will bring up the resolution up to 1440p. The problem I notice is that other LG models allow for forced resolution but the OLED series will not and just do the upscaling itself (only up to 1080p). My request for future update is to allow forced resolution to 1440p at 60hz refresh rate. Not sure if I worded everything right but still I appreciate your hard work. ??

Very impressive
I was impressed right away. Tested Xbox and Blu ray movies and confirm this response rate is very low meaning very very low motion blur. Great for FFS games. The only thing that isn't perfect is near black levels but for the price, I can live with that. Still a top shelf TV.

We bought this tv after researching many. We planned to drop season football tix and just watch at home. Then shelter in place appeared. Can't describe how clear the picture is. Wow is a good start for the difference between this and our poor tv.

Huge difference from my previous 4K HDR set.
This set was on sale and I was getting tired of the Dirty Screen Effect (grey scale uniformity issues with my prior side-lit 4K HDR set. On my old set, dark scenes would look awful, with very visible streaks showing. This set solved all my problems. The blacks are incredible, which makes all the colors pop in a really amazing way. Very happy with my purchase!
