    • Hard to believe this is entry level OLED!
Size: 65 Inch Style: TV Only
Review Image by michaelb1968 michaelb1968
This is my first OLED TV and I almost didn't buy it because of all the "entry level" chatter. I watched a few detailed reviews though and they all said the same things, which is that the TV is awesome, but there are others that are extra awesome and a lot of extra money. I am so glad I went with this. For starters, the picture is flat out sick. I cannot believe the difference between this and my other non-OLED 4k TVs. I am going to wind up going broke replacing them. The blacks and darker scenes are so crystal clear and perfect, no ghosting, no scaling, it is just perfect. What really knocked my socks off though were the 2 things that people were lukewarm on, and that is the sound and the remote. I included the pic to show the size of the room. I am standing 10 feet behind the sofa. This is an open floor plan with a bigger space than the picture shows and this TV fills not only the room, but the entire first floor and then some. The AI sound feature absolutely rocks! I swear it is equal to my Sonos Play 5. You can google cast to the TV too which is great. As for the remote, it is awesome. Sometimes the pointer is nice, but if you don't like it just don't activate it. The modes are seamless. Voice activation is great and you can search inside apps, not just outside. It has good weight and feels nice in hand. Total winner. LG Web OS is super fast and easy to customize. The LG Thin Q app is also nice and double as a remote. Setup was simple. I just don't know how anyone could not be happy with this TV. ... show more

    • Amazing TV at great price
Size: 77 Inch Style: TV Only
Amazing TV! Delivered on time and professionally (I paid a bit extra for the pro delivery service). TV looks great, sounds great and was a huge jump up from other LG tv that was not 4K or LED or any kind. LG makes great products - and at the price, this is a great deal!

    • Highly recommend this TV
Size: 65 Inch Style: TV Only
The TV is amazing. Great picture, even old tv shows look good. The audio is above average, but I would still use a soundbar or separate speakers for best results. If you’re 65+ (which I am) you’ll probably swear at the remote (which I did). It’s designed for someone with the dexterity of a 25 year old. But with practice, it’s manageable. This TV was a big step up from our previous HD set. ... show more

    • An Excellent Choice for OLED TV
Size: 77 Inch Style: TV Only
This is truly an exquisite television. The OLED system is one of the best on the market. The colors are incredible and the blacks are BLACK. We purchased a non-OLED tv for about half the price of this one, but the quality simply wasn't there. We returned it and ordered this one and are completely satisfied. Definitely worth the investment if you watch a lot of television. ... show more

    • Nice picture, weird mount, annoying remote.
Size: 55 Inch Style: TV Only
Great picture. Annoying remote. Bad VESA mount hole locations. We upgraded from a Samsung 1080p LED. Huge difference and really makes family movie night great. The route with it's wave around feature absolutely sucks. I stopped using it and only use the directional pad now. Much better. Wish you could disable the wand function. Since we replaced an older TV we already had a wall mount. The design of this TV has the VESA holes at the bottom and middle on the back. This causes the TV to ride high on the mount. It bumps up against your over TV cabinets. Finally the most important thing! Go in and disable LG's spy setting. By default everything you do on the TV is sent to LG for marketing and data mining. Disable this setting first. ... show more

    • Awesomeness
Size: 65 Inch Style: TV Only
Beats the socks off my Oder 10 year old LED top of line tv in the day. Only reason I upgraded is that my eyes needed upgraded too. Much more visible and larger picture, backlight viewing is incredible! The Dolby Vision/Atmos effect is awesome! Looking forward to watching sports in 4k. I haven’t even touched the surface on what this thing can do, but I will soon. Love the five year software updates it receives, one of the main reasons I bought it. Super easy to wall install using my 15 year old universal wall mounts but needs two people to carefully hang it. Lightweight and amazing to get this kind of picture with such a thin screen? Sound is pretty good, still would be better with a theater addition soundbar or theater surround system that I already have I just haven’t hooked it all up yet. ... show more

    • Very good quality and value.
Size: 77 Inch Style: TV Only
No problem with either the seller or the TV itself. Came packaged very nicely in several layers of protection. Delivered to my living room. And while this is not the top of the line TV, as they get fancier all the time, I would have a hard time telling the difference between the picture quality of this model and ones for twice the price. Any OLED looks great compared to my now 7 year old Samsung LCD. ... show more
