What people are saying

Rated 1 out of 5 by from Worst TV ever Zero stars really I bought this TV 30 days ago and all of a sudden the audio worked but no video. We returned the television to the store and purchased the same television again. Took it home, plugged it in and the new television has large white vertical stripes down the left side. I will be returning this TV tomorrow. Fool me once... twice but not a third time. I’m done with this.

Date published: 2021-01-11
Rated 5 out of 5 by from Perfect for Next Gen consoles and 4K movies My primary reason for upgrading my TV was for my Xbox Series X to be able to take advantage of the HDMI 2.1 features that it has (two out of four HDMI ports on this TV are HDMI 2.1 with a 40GB bandwidth. One of those ports is the eARC). I opted for the 86" Nanocell 90, upgrading from a 2018 70" LG 4K TV. That step-up in size was at first overwhelming to me, but I have gotten used to it and am very happy with this TV. I have owned projectors in the past and this is on par with that "big screen cinema experience" I enjoyed about those devices, but noticeably higher in quality and performance. The magic remote is a great feature for quickly moving around options and altering settings as needed. I have my set wall-mounted which I think is where it is at it's best but it will work on an entertainment center as long as you ensure you have one that is wide enough. This TV is very heavy, though, so do be aware of that. It's not easy to lift, and you certainly don't want to be moving it solo. Your mounting choice will need to be very secure. I have altered the color settings to get this TV to look exactly how I want it, and it hasn't left me wanting anything different. With my settings the blacks are black and the whites are white and I have a full color spectrum that I am very pleased with. If you feel something is a little off when you first start using it, don't dismiss it - make sure you play with those settings whilst using an onscreen reference (you can find them online or get a professional calibration if you'd prefer). It can make a world of difference to any TV. I have also installed a white LED light strip around my TV which I feel gives a nice ambient effect and further enhances the blacks on the screen, but this isn't really a necessity. If you're interested in doing the same, though, you'll need a light strip that is 20ft in length - that's how long the measurement around this TV is. I have mine set with the AMD FreeSync which I find works great. Do be aware that this will result in Dolby Vision not working, though - you will have to choose one or the other. I personally found FreeSync to be more beneficial for my needs as a gamer, but if you're only interested in streaming media then you'll likely want to leave that feature switched off so that you can take advantage of Dolby Vision instead. I had to run a firmware update (it's a very easy process on these TVs) to get the FreeSync option to appear, so if you find that it is missing then you likely need to do the same. I'm sure any of these TVs purchased in 2021 will already have that update applied, though. I use a surround-sound system so I can't really comment on the quality of the sound but the options look good and from my understanding this TV has adequate sound if you aren't able to have an external setup. It has eARC and can pass-thru Dolby Atmos, which is a nice touch, although I found this option to be too laggy in sound for my current setup and needs. I hope to be able to use that feature better in the near future. For the price I paid for this TV it is of outstanding value to me. If big screen, next gen entertainment is what you're looking to enjoy most out of this TV, I don't believe that anybody would ultimately be disappointed. As a nice bonus, it's power usage is also noticeably lower than my previous, smaller TV. I would happily recommend this TV.
