So stunning. So simple. Picture-on-Wall design allows the television to lie virtually flush with the wall so it seems to disappear, a feat only possible with uniquely sophisticated LG OLED TV technology. Beautiful on or off, it is the purest form a television can take and the ultimate in minimalism.

I bought this TV a few weeks ago and really like the quality of the picture. The only thing I have a problem with is the sound. It's inconsistent. I have to adjust the sound with different channels. I have the sound set on auto adjust but it doesn't seem to help. I like most everything else about the TV.

The picture is great. 4k from Netflix, Amazon Prime, and an LG 4K UHD/Blu-ray player comes through beautifully. The only knock on this TV is that there are only 3 HDMI ports: 2 regular and one ARC. I've got a cable box, 4K player, Nintendo Switch, and a sound bar, but have to purchase a separate HDMI switch in order to connect all of those devices. The bezel is nice and thin, which makes the screen really pop.I have yet to mount it to the wall, but it seems fairly straightforward (takes VESA 300x300 mounts), so it shouldn't pose an issue. I'm not particularly a fan of the stands (one on each side of the unit) - I prefer a center stand - but as I plan to mount it, this won't be an issue for long.The sound is pretty good for TV speakers, clear and loud enough. I have a vaulted ceiling (16ft), so sound can get pretty lost. This also has some built-in sound adjustments. Once I get a multi-port HDMI switch I will be able to use the sound bar through ARC with all of the devices, which will sound better than the TV speakers anyway. That being said, the sound is suitable for regular viewing; it just won't give you the full theater immersion feel all on its own.The setup was a little frustrating, but only until I realized that I need to get an HDMI switch so that I can use ARC for multiple devices. Part of that issue, though, is also with the sound bar that I have (not an LG device), as it only has one HDMI input and one ARC output. Had I realized this (for both devices) from the beginning, setup would have been nice and easy. I like how the TV will scan for your connected devices, plus you can change the icons and names for the devices to make it easy to remember what's connected where.Overall, it's a great picture, good sound, (relatively) easy setup, and needs at least one more HDMI input for today's devices. I would recommend this one, but would consider upgrading for more inputs as well.
