Affordable OLED that Delivers
||Posted .Owned for 1 week when reviewed.We had an older M-series Vizio before purchasing this LG that began to have backlight problems after only 3 years. We decided to spend a little more on our next TV to avoid that issue again. I've always known how amazing OLED panels look, but they were never in a realistic price range for me (and most consumers, I think). We were on the fence between this OLED and a Sony LED tv. Both were the same price, but the Sony came with some additional goodies (i.e. high-refresh rate, brighter, etc.). Since we don't do much gaming on our TV, we went for the OLED. The LG A1 has seriously impressed. After a few weeks, we are still blown away by the contrast of the OLED. Pros: - TV is very thin and built well - LG webOS is very good, and their remote is amazing. I didn't know what I was missing until I got their pointer remote. It's like a mouse for your TV (reminds me of a wii remote). - The insane contrast makes even mundane scenes look amazing. The color also really pops. - 1080p content upscaling looks excellent. - For an OLED, the price is good value (assuming it holds up). - Viewing angles are perfect. You can sit anywhere in the room and see the content perfectly (benefit of OLED) Cons: - I wish the TV came in a slightly smaller size. 55in is nearly too big for our space, but we're in a unique scenario where we have to put it in a corner. - The TV doesn't get quite bright enough for really good HDR. This can also be an issue if you have lots of sunlight coming into your living room. It's never dark.... but it also doesn't get THAT bright. - Burn-in risk.... but this applies to all OLEDs. We don't watch any static content or content with static banners...so no issue for us. Overall, we're very satisfied with the TV. It's hard to see just how good OLED looks in a picture, but hopefully the photo helps. Crossing our fingers that it works much longer than our Vizio did.

LG life-Samsung switch.
||Posted .Owned for less than 1 week when reviewed.Only had my tv less than a month and still figuring out some interesting operating system things like the frequent upgrades. Will call geek squad to trouble shoot. With streaming the picture is as beautiful as in the store- especially with 4K shows/ movies. The sound is amazing without a sound bar but my living room is a modest size and it isn't needed. LG has its own streaming app and the picture quality is poor but it would be my wifi- still need to figure that out but overall for $1K price worth more $850 in my opinion. It took alot for me to switch from Samsung.

They showed me what it could do, and I am not computer savoy. Thank goodness my daughter was here and totally understood what they were talking about. I couldn’t be happier with the product, the installation or Best Buy service. I will always buy there 1st from now on.

Great TV with a few flaws
||Posted .Owned for 3 weeks when reviewed.I will preface this by saying I got a Geek Squad certified open box TV. I do love this TV, however, it does have significant lags - which I never experienced on my previous $250 TV. For >$1k, I expected better performance, less lagging between apps & the LG home interface is not the best designed UX. However, the picture quality is phenomenal & the build quality of the TV is great. I also like the “pointer” function on the remote. It is often more convenient than clicking through menus and I find it to be very accurate.

OLED is in a league of its own
||Posted .Owned for less than 1 week when reviewed.I'll start with the cons. These are all pretty immaterial to me, but may be important for some folks. -The remote is not backlit. The feel of the remote and buttons doesn't lend to easy operation in the dark. -Menus were not designed for casual, non-tech folks. -The TV feels very delicate. It's 100% bottom-heavy, and the thin top half of the panel should be avoided. -Burn-in risk. This is more of a FYI for readers. The TV has mechanisms to mitigate this when it's left turned on and idle. Read up on burn-in, and take what you learn into consideration. The last thing you want is to have a TV of this quality experience burn-in. I realize there are better OLED sets out there, but for the price, it's just not fair that we have a set as good as the A1 available to us. This TV is the best we've ever owned. It's not even in the same realm of quality as any other TV we've owned. This TV is on a whole other level. The picture quality in 1080P is stunning. The picture quality in 4K is mind-blowing. The picture quality in 4K HDR is breathtaking. Colors are crisp, rich, and accurate. Sharpness and contrast were perfect out of the box; no adjustment was necessary. If you see this TV in demo mode in store, know that what you see is what you get. The quality you see in demo mode mirrors the quality you'll see during actual use. I've seen several reviews mention that the TV is lacking in brightness. Brightness is sufficient enough to continually trigger my indoor camera's motion sensor...even during the day. We have this TV in our generally well-lit living room, and there is no indication of reduced brightness. Sound quality is top-notch, considering that the speakers are 20W. So far the built-in AI sound has worked well for us. Some movies have been a bit too loud, but that's not the fault of the TV. Lows are adequate, and highs are crisp. If you're placing this in a larger room, a sound bar may be a nice addition. Sound will be automatically adjusted based on TV placement (wall-mounted or on the included legs), which is kinda nice. Available connections are adequate. A 4th HDMI port would've been nice, but 3 ports is probably sufficient for most people. Component and Composite connections would've also been a nice "just in case" addition, but it is 2022 and I can understand why they're omitted. The 2 USB ports are great. In testing them, they were able to play files in mkv and avi format. The coax input is great for folks like me who watch OTA channels from time to time. The TV picked up 96 OTA channels in out area; about 20 more than our previous TV. We have the TV wall-mounted. The 300x200 spacing was unusual to me, but given how the TV is built, I understand it. The swivel mount we used had spacers that were able to accommodate. The TV's mounting holes accommodate for longer screws, so there's a bit more peace of mind when placing it on your wall. The TV's extremely low-profile makes for a very clean and sleek wall-mounted look.

Q: QuestionWhat is the difference between "A1PUA" and "C1PUB" LG TVs?
Asked by Anonymous.
- A:Answer OLED C1 series is a more advanced OLED than the A1. The differences between the A1 and C1 are greater output power, additional USB port, the latest HDMI, version 2.1 (4K@120Hz) and a faster processor. You can see the link for a side by side comparison of the two models, https://www.lg.com/us/compare?bizType=B2C. ^Daphane

Q: QuestionIs it recommended to buy an Apple TV to go along with a smart TVs
Asked by Rabbit.
- A:Answer Ive found Apple TV to be a wonderful addition. It affixes to the back of the TV, plugs into one of the spare USB ports, and with a 4K HDMI you get Dolby picture from Apple. Besides the additional TV options, including Apple TV exclusive content including their movies and shows, my favorite feature is how all of the music videos purchased through iTunes is now loaded on Apple TV. So I can run my 80's videos for hours.

Q: QuestionDoes this TV have a 2.1 hook up for next gen gaming? Also does it have the same contrast levels as the C1 OLED
Asked by RainbowHeart.
- A:Answer This TV does not have any version 2.1 HDMI inputs and will not support 4K@120Hz. I cannot compare because LG does not measure contrast ratio anymore because there is no measurement standard that all companies follow. ^Daphane
