MY Best Television Purchase EVER!!!
|Posted .Owned for 1 month when reviewed.Features
Quality5 out of 5Value5 out of 5Ease of Use5 out of 5I upgraded to this tv from my previous 2019 LG OLED tv which was in perfect working order, but I have the new Sonos Arc sound bar which isn't compatible in giving me the True ARC sound I wanted from the 2019 OLED. So I upgraded to this CX series which has the compatibility of the Sonos Arc and I wasn't disappointed! The TV is awesome as the previous but when I combined it with the soundbar....OMG!!!! I'll never go to another movie theater ever again.. why should I when I have one with surround sound right in my own living room. This is a great purchase!

Love this TV
|Posted .Owned for 1 month when reviewed.Features
Quality5 out of 5Value5 out of 5Ease of Use5 out of 5This tv is amazing. I returned my Sony A8H for this tv, not saying the Sony wasn’t a fantastic tv because it certainly is, but the LG has the additional gaming features and after having both, the difference in movies is borderline indistinguishable. Sony has the upper hand with its processing and up scaling of non 4K content into 4K but native 4K content, they’re virtually neck and neck. I love playing my Series X in 120fps for games that support it. I also use my Apple TV 4K to stream in Dolby Vision and that is just eye candy! I got the tv on sale for $1349 during the pre Black Friday special and I would get another one for my living room if it wasn’t almost $2k again. This is definitely a future proofed tv and don’t worry about burn in, LG takes plenty of steps to make sure your tv display will prevent burn in. (It’s not impossible but if you watch varied content without a ton of static images, you’re golden)

Amazing Desktop Screen
|Posted .Owned for 3 weeks when reviewed.Features
Quality5 out of 5Value5 out of 5Ease of Use5 out of 5Using this TV as a desktop monitor. It replaced a high end 55" Samsung and what a difference. Once you get it dialed in for the PC the performance is amazing. I have a high end video card but it doesn't have enough bandwidth to feed this TV's HDMI 2.1 capability so now I can't wait for the latest PC video cards to purchase one so I can unleash the real power of this already amazing screen performance. Highly Recommended!

Amazing picture, decent UI, short stand
|Posted .Owned for 2 weeks when reviewed.Features
Quality5 out of 5Value4 out of 5Ease of Use3 out of 5Picture: First off, the picture is amazing. I use the CX 55" with my Apple TV 4K and Sonos Arc to enjoy 4K Dolby Vision and Dolby Atmos content.** I have the Picture mode set to Cinema, which seems to provide the most accurate color. For those that prefer it a bit brighter, there is also a "Cinema Home" mode that still provides excellent color. No issues so far with banding or image retention. UI: Plenty of picture customization options, although I wish the descriptions in the documentation were more clear on the specifics of what's being changed for each setting. My biggest issue with the webOS UI is that the app order cannot be customized. The only two options are the default, and an option to do a "smart" reordering of apps based on your usage. This is made up for with the ability to setup Quick Access, in which you can assign a specific input/source or app to buttons 1-8. Cons: Probably the most annoying thing is how the TV (doesn't) automatically power off. It doesn't seem to communicate with the source devices as well as my Samsung 4K TV (2018). While it automatically powers off when I turn off the Apple TV 4K, I cannot say the same for the PS4 Pro, Nintendo Switch or Xbox Series X. Rather, with its perfect blacks, the TV looks like it's off, but then you can hear it click off several minutes later due to lack of activity. Remote: The LG Magic remote is a bit on the large size, and is certainly an adjustment coming from the simplicity of the Samsung Smart Remote. It's not a bad remote, but it's a little more traditional, and I could do without the dedicated Netflix and Prime Video buttons. **HDMI 2.1 (aka Ultra High Speed HDMI) cable may be required to use with Dolby Vision and Dolby Atmos over eARC. The TV displays a helpful popup notification in the corner when the image being displayed is HDR or Dolby Vision.

Best tv on the market
|Posted .Owned for 2 weeks when reviewed.Features
Quality5 out of 5Value5 out of 5Ease of Use5 out of 5Best Tv I have ever owned and at this price is unbeatable. Picture is A+ quality. If you aren’t considering this tv you will regret it. Oled is definitely the best. Tv also doesn’t lag at all when making selections and having the smart remote I can just point and click rather than using arrow keys. Sound is amazing too! Also don’t forget the Gallery mode turns your tv into a framed picture.

Amazing OLED TV or computer monitor
|Posted .Owned for 1 month when reviewed.Features
Quality5 out of 5Value5 out of 5Ease of Use4 out of 5This is my first OLED TV and was a little worried about a few things going into this tech. However after a lot of research I decided to go with this one. It has features built in to really help against burn in, which I have heard can be a problem with OLED but not ever having one I can't confirm. There is a very nice screen saver built in, as well as pixel shift. Pros: The color black is just amazing on OLED. It really makes even older shows just pop and also stuff in 4:3 you get a black bar on the sides you almost forget the TV isn't widescreen. Games look amazing on this thing. I have tried a few consoles and a PC on it. Even the Switch looks fantastic on this thing. The audio speakers built in are not that bad. Usually I expect on most TV's these days to have some weak audio. But this came out really nice. There is an optical output as well so I could hook into my sound bar. Bluetooth headphones will also connect to the device, so if you want private viewing or don't want to wake or keep everyone up it is a nice option to have. Pretty smooth smart TV with the programs launching quickly, however not my favorite interface, but I could get used to it. The quick launch features are also helpful, common apps pop up with quick hit of the home button on the controller. The OSD is really quick to respond and has a lot of quick access features for sound and picture. Also the ability to quickly apply settings to all inputs saves a lot of time on things like reducing brightness across the board. (see picture) Was also pleased how easy was to label each input when I was setting the thing up Cons Not sure this is applicable to everyone but the LG remote seems to use the same connection as a LG monitor I have in the same room, so I have been using my phone as a remote for my TV instead of the remote it came with to turn it on and off. WebOS has not been my favorite Smart TV software. The app selection is okay but at the time of writing this HBO Max is still missing. However the quick pop up of apps listed by pressing the home key is pretty nice. Update: I saw some people say GSYNC didn't work for their PC. I was able to get my RTX 2070 super to work fine with it. However you need to have a updated HDMI cable. I purchased a 2.1 version and had no problems and it looked amazing.

Best Gaming Tv Awesome Picture
|Posted .Features
Quality5 out of 5Value3 out of 5Ease of Use5 out of 5Pros mentioned:Gaming, PictureCons mentioned:Burn-in, SpeakersProbably the best gaming tv you can buy right now. It’s got an awesome picture only bested by the Sony oled and i would recommend that one if all you watch is tv and movies plus it got a big price cut. But if you game the lg cx has everything you would want. All the hdmi ports are 2.1, it has variable refresh rate, and its freesync premium and gsync compatible. The only con is burn in but if your scared buy a warranty. If you change your content often enough and don’t leave it on the same thing day in and day out you should be fine plus the tv has fail safes built in to protect it. Once you go oled it’s hard to go back to lcd or qled they can’t match the inky blacks of oled but qled’s can get very bright. If you looking for something other than oled the Samsung q90t is a great tv for gaming. And if you want something even cheaper the tcl 6 series is a great tv for the price I love the roku operating system it’s simple but effective. I love the cx and think its the best tv you can buy right now in the us and you get a free lg xboom bluetooth speaker with proof of purchase until November 11th.

Great TV for PS5/XBOX and all your movie needs!
|Posted .Owned for less than 1 week when reviewed.Features
Quality5 out of 5Value5 out of 5Ease of Use5 out of 5I had been eyeing this tv against the Sony 900h for awhile. I have a TCL P607 I bought for my pro in 2017 still in use. I received a PS5 on launch and needed an upgrade. Got this one for my bedroom! Believe me OLED is a different world! 4k,hdr yeah all great. But even at 1080p this tv looks fantastic! Highly recommend for consoles and movies. Also get the 5 year warranty. Take it from me! I worked at Geeksquad 6 years as a FT ARA. I’ve seen a lot of TVs, and worked on some. This is by far the best tv at this price and for gaming! You will never go back to a IPS or VA panel. Just be sure to get the warranty and put it in a man cave or safe are with pets and children. The screen is thinner than my pinky!

Q: QuestionAre current LG OLED TVs less susceptible to screen burn-in than earlier models? I am replacing a 2016 model that developed burn-in of the CNN logo. I’d love to get a new OLED, but I’m afraid burn-in will reoccur. Would I be better off with a QLED set?
Asked by KYJim.
- A:Answer Hi KYJim. I have a 2015 LG OLED that my kids play games on and I watch a lot of CNN, MSNBC and Jim Cramer on and I don't have any hint of Image Retention or Burn-in on it. Burn-in and image retention are possible on virtually any display. It is rare for an average TV consumer to create an environment that could result in burn-in. Most cases of burn-in in televisions is a result of static images or on-screen elements displaying on the screen uninterrupted for many hours or days at a time – with brightness typically at peak levels. So, it is possible to create image retention in almost any display if one really tries hard enough. And even if image retention does occur from extreme usage, it can usually be mitigated within a short period of time by turning the display off for a while, and watching a few hours of varying content (such as your standard TV watching and channel-surfing). Additionally, the LG CX 55 inch Class 4K Smart OLED TV w/ AI ThinQ® (54.6'' Diag), Model # OLED55CXPUA comes with special features and settings to preserve image quality and prevent burn in and image retention. First, under OLED Screen Saver there is the Pixel Refresher that calibrates any issues that may arise on the screen when your TV has been turned on for a long time. Calibration takes more than an hour. The second feature that can be employed is the Screen Shift feature which, moves the screen slightly at regular intervals to preserve image quality. A third option is the Logo Luminance Adjustment, which can detect static logos on the screen and reduce brightness to help decrease permanent image retention...^IFV

Q: QuestionReflection, Glare and Brightness, Burn in. How concerned should I be about this? Samsung for 13 years zero issues with the TV. I am debating LG CX 55 or Samsung Q90t. I assume people watch their OLED during the day or morning right? I want to switch but..
Asked by jeff.
- A:Answer The LG CX 55 inch Class 4K Smart OLED TV w/ AI ThinQ® (54.6'' Diag), Model # OLED55CXPUAuses emissive technology and doesn't have a backlight, which means that the pixels can turn off completely to produce perfect blacks. And since it doesn't rely on local dimming, there aren't any issues with blooming around bright objects or subtitles. It gets decently bright, enough for a moderately-lit room, and it handles reflections exceptionally well. Viewing angles are great, so the image doesn't degrade if you're seated off to the side. Burn-in and image retention are possible on virtually any display. However, with an LG OLED TV, any risk of burn-in or image retention have been addressed through the use of technology that not only helps protect against damage to the screen, but features self-healing properties so that any short-term image retention that may occur is quickly rectified. It is rare for an average TV consumer to create an environment that could result in burn-in. Most cases of burn-in in televisions is a result of static images or on-screen elements displaying on the screen uninterrupted for many hours or days at a time – with brightness typically at peak levels.

Asked by Antennaboy.
- A:Answer The LG CX 55 inch Class 4K Smart OLED TV w/ AI ThinQ® (54.6'' Diag), Model # OLED55CXPUA does not have a NEXTGEN TV (ATSC 3.0) tuner. The six 2020 LG OLED models that have built-in hardware to support the NEXTGEN TV (ATSC 3.0) tuner are: the 55-, 65- and 77-inch class GX Gallery Series 4K Ultra HD models, the 65-inch class WX Wallpaper 4K model and 77- and 88-inch class ZX Real 8K models. These models will receive a firmware update that is required to activate the tuner which will automatically be pushed out later this year. This will be a staged rollout and as you have mentioned, it will be rolled out when your market begins NEXTGEN services...^IFV
