      1st 4K TV


      I had been debating between this or one of the Samsung's. I took a gamble with this since it is so new to Best Buy, that it didn't have a review yet (at the time). I love this TV. Of all the TVs that I have owned, this one so far is the best. Not just picture quality, but also the sound. I'm also a gamer, and I'm hearing more of the "bells and whistles" that I didn't have with the other ones. The picture quality is awesome, and I never owned a TV that offered Bluetooth. The smart side of the TV has a small but decent selection of apps. You can have Netflix, Hulu, IHeart, etc. with a few other apps, just bear in mind that if you are use to a Roku, you could be slightly disappointed. It does have a decent web browser, if you don't mind using the remote to type. I haven't tried to see if it accepts a Bluetooth keyboard yet. I know there are probably better 4K TVs out there than this one, but for $550, you cannot go wrong. Having said that, if I had to have one con, it's the plastic pedestals that come with it. They are nowhere as good of quality as the TV, but if you are going to mount it, that will no longer be an issue. All in all, for a great, inexpensive 4K TV, you cannot go wrong with this LG model.

      Great Experience!

      • Verified PurchaserVerified Purchase

      Our 9 year old 50” plasma TV needed to go because it was just time to update and get new features like Amazon Prime, Netflix, YouTube, etc. But, buying a new TV these days can be quite a challenge. Yes, we wanted 4K, HDR, UHD but we also wanted all that on a budget. So I went to Best Buy because I needed some input from pros, and I was pleasantly surprised with how they made a daunting task much easier. After deciding on this LG TV, I added delivery and setup to my purchase. Both the TV and the delivery/setup was money well spent. I feel like the sales associate did an excellent job showing all the options we had and the Geek Squad handled delivery and setup on time and with efficiency. The TV itself delivers a stunning picture and the sound is so good we don’t need a sound bar. Because the room this is in leads to fairly wide viewing angles we wanted a TV that could handle that - and this TV delivers, with specific technology that maximizes viewing angle without loss of picture quality. Bottom line ... Best Buy and LG made purchasing a new TV a very pleasant experience and we are very pleased with how well this was handled from start to finish. Thanks for a Great Job!

      Not overly impressed with this TV

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite Plus MemberElite Plus Member

      Not overly impressed with this TV despite the great reviews. This is my first LG TV as I have preferred both Sony & Samsung brands. Upon initially loading HULU, Netflix and Prime, I was asked to update all apps. This was fine but it is a bit concerning that every update will delete any saved data in these apps. Also, each app takes up space on the TV, which will wont take long to use all of the space up. The 2nd day of owning this TV, I was commanded to update the software in the TV. This update kicked out my network connection so I needed to reconfigure it. The 3rd day I was asked to update the Netflix and Hulu apps again! Further more, this TV is mounted about 20ft from my router. However, the connection is horrible. My shows continuously stop and sometimes won't go back on. I have a Samsung TV mounted about 70 ft from the router and it works just fine. I have purchased a Net Gear WiFi extender, hoping this will be the answer. Lastly, I do not think the 4K picture is all that great compared to my other TV brands. At this point, with the TV mounted and original packaging disposed of, it looks like I am stuck with this TV. But I am pretty sure this will be my 1st and last purchase of an LG TV Brand.

      Great TV and WiFi OS. Mounting Feet Stink

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      The TV itself has a great picture, and the sound is way better than our previous Samsung. It was very easy to hook up but the support feet it sits on are horrible. The TV is unstable and would rock back and forth with the slightest provocation. If you have kids or dogs then mounting it on a wall is a must. Our old Samsung had a stable glass base but this LG has little plastic click on feet that just don't do it. The best buy sales rep that helped us assured us that voice operation was built in to the remote... not so though. Turns out there is a fancier magic remote you must buy for this. The good news is that Alexa works fine with the TV. We had no problem getting Alexa and the LG TV on speaking terms. You can't turn it on with Alexa but they promise that is coming. We can do the following so far with Alexa... TV off; Volume up/down/value/mute; change input; rewind/fast forward/pause/stop; change input. Switching to Netflix / Amazon / cable is really easy. We like that a bunch.

      Worth the wait

      I've been waiting about a decade to upgrade from my former Samsung LCD TV. As ultra HD came out I resisted the urge to upgrade until the price dropped and finally, after a recent move, I made the upgrade. I have NOT been disappointed. The ultraHD on this TV is great. IT really shines when the HDR kicks in on games and movies. I've also been pleasantly surprised by the LG OS. Learning an OS can be a struggle, but this worked fine. My ONLY complaint was that the TV remote wasn't compatible with my Bose Soundbar and, after checking tons of LG blogs, there isn't a workaround. But, I traded it for a (nicer) LG soundbar on FB marketplace and have loved that since I got it.

      Better than review sites say, but poor value.

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      It does some things really well, and the IPS screen is useful for viewing angles and TV is great with glare. There's a lot to like about the picture and functionality . Should have included Magic Remote. Unfortunately there are better values in this price range, especially bc you'll want to buy a stand (I don't trust the legs) and the upgraded remote to use its full capabilities, but if you don't care about voice control or already own a stand or mount it helps. I wish it would have worked for me, but I just happen to use it most for the things it's weakest at, like blacks and dark scenes. If the IPS screen is better for you this is your best budget TV bet.

      I read a good amount of reviews in this and other models in the same range all over the web. I read many positive things about this particular TV, and some negative ones. However, in my experience this TV has proven to be a great budget alternative for a 4K TV. The image is great, Wi-Fi functions perfectly, everything just works as good as I need it to work for me to enjoy the TV. Also, the folks at Best Buy were very helpful when picking a model. I was between this one and the Roku 5-Series. In the end it came down to choosing an LG as my previous TVs have all been LGs and I've had a good experience with all of them.

      Solid TV at a great price

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      This TV looks pretty good and wile considering everything including the price I am very happy with my purchase. What I loved was the specs on the TV and most importantly HDR. The picture is clear and maybe a little dim but considering that this is being used in a bedroom to watch mainly non 4K content it doesn’t bother us. Speakers are surprising and provide good enough sound for the room that I have turned on the sound bar. One upside is that this TV is $14 a year to run which is nothing compared to the original Plasma that was replaced by it. So if your looking for a really nice higher middle of the line TV give this one a look.
