Great TV minus the halo
For me it’s a 5 star TV. I’ve had this TV for close to a month now (bought for Prime Day) and I’m happy as I haven’t had one problem. I was a little worried reading some of these reviews but the box came in perfect condition and the TV has not given me one problem. The picture is beautiful to a person who hasd a 2013 LG TV before. The colors are vibrant, it’s really great for my husbands gaming and the sound is good for TV sound. I did however do quite a bit of research before purchase and there’s quite a lot of emphasis right now on OLEDS and how black their blacks are. This TV does have a halo around something white on a black screen. This is not something I would have noticed if i hadn’t researched it and I don’t think the average person will be put off by it but someone used to the luxury of OLED or just really high end TVs might.

Great picture!
I bought this on Memorial Day half off special, so my review is biased by the $500 sale price tag. So, that being said...WOW. Awesome picture quality. It feels like a $900 tv to me and I was thrilled with my sale weekend deal. Having viewed less expensive LG Nanocell models in person at Best Buy, I knew it was a noticeably nicer series than the $400 - $450 range LGs in my budget. I liked LG a lot in general as a mid-tier option between really unimpressive TCLs and Sony (which always looks amazing to me). I think the picture is so crisp on this LG model I feel like I am getting something Sony quality. Really appreciate the 8 picture modes, too. Pretty intuitive remote and no complaints about sound without a soundbar (though that’s not my area of expertise). Also will note I did “to the door” Amazon delivery and was happy that delivery guy moved it inside a little for me. You should take the tv out with an extra person but I live alone and had an easy enough time doing it myself (not a super muscular, medium build woman).

Great picture and easy setup.
I purchased my LG 55SM8100aua from Vanns (through Amazon) a number of weeks ago and couldn't be happier. I ended up purchasing this tv for $489.00 which was the best price I could find anywhere including online and brick and mortar. The tv arrived as scheduled and packaging was excellent. I replaced an 8 year old LG tv so I was concerned about the potential difficulty of setting this up and I couldn't have been more wrong as set-up was very easy. The picture and quality of this tv is excellent and I really like how small the bezel/framing is around the picture because when the tv is on all you see is screen and not framing. Also, the sound quality is a big improvement from my older tv. Just a quick statement regarding set-up, I connected the HDMI to my cable box, turned on the tv and followed the easy instructions and I was watching my new tv in a matter of a few minutes.

good tv
Good tv for the price for sure, i would give it a 4.5 now but originally woulda gave it 3.5 cause the interface wasnt great out of the box. It took a few months and a few updates and the interface in now smooth as silk. same with pretty much any tv now a-days the sound is terrible, sound bar recommended

Super Picture, Some initial issues with Smart Apps, Magic Remote leaves me wanting
The picture is great. The sound (for a flat screen tv) is pretty good, but doesn't have the depth of a 5.1 sound system. Some issue with YouTube TV existed at first - latest software updates seems to have corrected problem. The Magic Remote works (sort of) but does come near what a Harmony Remote can do. The Magic Remote lacks controls for my Samsung BluRay DVD player. The ARC HDMI functions performs well with my soundbar 5.1 system.

Favorite tv
I was looking for a tv. I went to Sam's Club first. Saw a few options but I wanted to see if amazon had it available also. They did. For $49 less. So I saved it. I few weeks later I received an email from amazon showing the tv was on sale for a $200 difference. I instantly purchased it. Love this Tv. The auto adjusting is wonderful. Picture is better than the latest phone. Super smart tv. Im glad I purchased it.

Nice Picture but the remote, eh
The picture was great. I grabed this when I saw the price drop. It was between this and a Samsung a $100 more. I looked on Consumer Reports and this TV scored higher slightly so that sealed the deal for me. The remote is my only gripe and even it isn't bad, just slick (slipped out of my hands twice) and not well organized in functions. Lastly the mouse arrow on the TV for navigating the menus using the remote, All I can say is its an exercise in patience. It functions like a WII remote but not as good.

Damaged item
Side of the box has a few deep cuts , upon unpacking I've noticed a big dent on the TV screen , I am returning this item ASAP , ordered a replacement , will see what happens . Received a new unit today , seems OK , no damage this time , good quality picture and sound , changing rate to 5 .

Like the screen size and borders. Works as advertised. Have not played any 4K media but the other res works well enough for me. Only thing I’m disappointed about is the black screen quality. Used the smart features and set it up but don’t use it as it’s way slower than my Nvidia Shield.
