Rated 5 out of 5 by from Just upgraded from a smaller LG, very happy, 2nd LG tv

Rated 4 out of 5 by from Crisp picture Had this product for one year now and it is crisp and clean with great sound

Rated 4 out of 5 by from Awesome picture I purchased this TV last year. The picture is very realistic, even on some of the older movies I watch. The 3D is amazing! The set up was easy and I'm not tech savvy by any means. The remote is nice sized. The buttons are easy to operate without hitting two at the same time. It's extremely easy to use. I still haven't mastered all there is to know about the TV but over all I'm extremely happy I bought it.

Rated 2 out of 5 by from Backlight bleed or ghosting is horrible do not buy I bought this tv as soon as I got home I noticed the bright lights in all 4 corners. Contacted the store I bought it from said they saw what I meant and would ask a rep. After about 2 weeks the rep said this is normal. I asked about a return the store said they had a 2 week return policy. I later contacted lg they remoted in through an app said they are the problem of the bright lights in the corners. He told me to turn on local dimming which I knew helped some but was still real bad and caused more of the ghosting issue and he still saw the 4 corner lights flashing. He put me on hold came back and said this is the way this model tv is. I was amazed that lg has a tv that they know the backlight bleed is this bad and basicly their answer is we know and you are out of luck. I wish I would have bought a lower end tv. You shouldn't habe this with a 1600 dollar tv. Only reason I give the t.v. 2 stars is the user interface is awesome. I would love the tv but can't get past the 4 corners being like someone is shining flashlights down my tv. Real bad on widescreen format movies. Like I said local dimming helps some but there is nothing you can do to the settings to fix it trust me I have tried several several several times. I have another lg t.v. that has been awesome for about 6 years and that's why I went with lg this time but this maybe my last.

Rated 3 out of 5 by from Sound problems Some times when I turn the TV on there is no sound. You must change to another channel and back for the sound to come on. The TV needs better sound controll.

Rated 5 out of 5 by from Solid 4k/HDR performance with good built-in apps I've had this TV for over 6 months now, and I've used it with many external devices. the color quality is excellent, it starts up quickly, and the remote control is versatile. Experiencing streaming videos in 4K is impressive, and the built in apps are above-average, compared to other built-in apps on Smart TVs. The voice recognition for searches on the remote is convenient, and it is as accurate as you would expect (which is to say, far from perfect, but usable). The default list of apps running down the bottom of the screen is a bit inconvenient, but I consider these two minor details not as important as the quality of both audio, video, built-in OS apps, channel listings, and other strong capabilities of this TV.
