Ruins you for DVDs.

MichaelAugust 2, 2020

My old HDTV was starting to have issues which went away after it was on for a while, but this means it would eventually fail. I wanted 4K. I wanted high quality. I needed it to be no more than 40” wide. Once you go under 43”, most units are 1080p and not 4K. I saw an older version of this one in a store. Shopping online I saw this newer (2020) version. Item arrived well packaged. I swear this thing is lighter than the smaller HDTV it replaced. I went with a tabletop stand as the feet for this unit (as is with most of them) are too far apart for the TV cabinet we have. First, you should know that the human eye can’t see in 4K resolution. How this applies is simple. With HDTV, you NEEDED Blu-ray with larger sets or you would easily see the “artifacts” from DVD video compression. On smaller sets, the quality difference was less obvious. Well, 4K makes it obvious...period. Watch a DVD mastered for HDTV and it’s like watching a DVD of a show recorded in the old TV format. HDTV was sharp enough to let you spot how much a show was filmed on a studio set and with studio lighting. Well, 4K will give you the same effect on shows recorded for HDTV...it’s that much of an enhancement in video quality. So, if your old HDTV shows on DVD look worse, this is why. Second, there is a learning curve to this TV. No buttons on the set, so you depend on the remote. There is an app for iPhone and iPad to interface over a network, and the TV can connect via Ethernet cable or WiFi...giving anyone with the app some control over the TV when it’s on. There is almost too many features, and the manual is pretty pathetic for showing you how to use the remote. Expect to spend some time tinkering to get used to the remote even though it is somewhat intuitive in its design. Third, the ability to have Internet channels is of dubious value to me. I wish all of them could be deleted from the home screen, but it seems some have proprietary placement and can’t be deleted. Watching these channels will consume bandwidth, so if you normally stream video, you may like it. The most value it offers at this point is adding a weather channel so we can get the weather situation on demand. Built in sound is adequate. If you want to try it as is before paying for external speakers, you might be happy as it sounds out of the box. Didn’t rate LG tech support as I’ve not needed them so far. Read more

Perfect upgrade to previous LG

J. A. LambertDecember 5, 2020

I bought this for my bedroom to replace a 43" LG model that did not have the SmartTV features. This TV is perfect. The picture is beautiful and the SmartTV features are exceptional and easy to use. I especially like the energy-saving feature for bedroom use. At night I turn it to maximum with a single click and the TV dims way down for watching in the dark as I drift off to sleep. Then in the morning I can turn off the energy saving feature and in a single click the picture is bright and vivid for daytime viewing. The LG WebOS SmartTV is great - we have this on our larger LG SmartTV in the living room. LG fans already know how nice this is, but if you are new to LG, its important to know that this interface makes it SO simple and seamless to switch back and forth between all the streaming apps right from the TV. Amazon Prime, Netflix, YouTube, Hulu, Cable Box, Google... its all right there on the menu and all can be controlled from a single remote. Just perfect. Read more

Happy with the replacement

Spencer KosiorFebruary 23, 2021

After several weeks/months with the replacement TV, I can say this is a splendid TV. Clear and crisp picture that could appear "realer" than life when properly calibrated. Blacks can be super black and whites as bright as the sun. I found myself futzing the most between brightness, contrast and backlight settings switching from gaming to streaming video. HDR is vivid but the backs can really get crushed. Dynamic Tone Mapping setting helps I found helps in those situations. Most of the other "additional display settings" like Super Resolution and Dynamic Contrast are trash... Unless you want everything looking like a low-light Instagram video. ### Original post: There was a bubble in the screen. Broken before I even took the plastic off. Will update once the replacement comes. Read more

A+ for picture and features and value for the money.

Kim O.October 16, 2020

Love this TV! Great ultra HD picture quality; I can see every hair out of place on someone’s head. The blacks are black and the colors are vivid. The remote with mouse capability is fantastic, and it has buttons that take you directly to Netflix and Prime Video - do they know the audience or what? The only thing I would improve is the user manual. It’s very light - come on LG, waste a little more paper already, and beef it up. I was able to get everything assembled and running in 30 minutes, but I’m handy, and an IT professional. If you’re not, it might not be as intuitive. Overall I give this TV an A+ for picture and features and value for the money. Read more
