    I would rate the 65″ CX as a 5/5 TV, but the number of software issues/bugs I’ve experienced have made me very upset. I would actually pay more money to get most of the “smart” features removed. I will update this review if they update the software.My Setup: Apple TV 4K, PC with 2080ti, 7.1 surround sound receiver.Picture/Image Quality: [6/5] Superb. You can’t beat LG OLED, and this is no exception. Best color, black levels/contrast, and overall image quality I have ever seen. 4K HDR/Dolby vision is *spectacular*. Only warning: Display is very glossy, so make sure this is in a dark room or opposite a dark wall as any light source behind the viewer will be visible. Right now I am running 4k60 for movies and 1440p120 for most games. There are no HDMI2.1 sources as of this review so I can’t test 4k120 gaming on it yet but I am hyped to! TruMotion is useless, just turn it off. I actually prefer the smoothness, but the artifacts are unreal. Any scifi show with star fields is a great example, the interpolation makes tons of mistakes and glitches out constantly. LG Engineers: Load up The Expanse on Prime Video with TruMotion set to “smooth” to see exactly what I mean.Sound: [5/5] Not used at all (I have it running on an external 7.1 setup), but it’s fine for on-tv sound. That said, who on earth uses on-tv sound on a $3k TV?!Software/OS: [1/5]. BUGS FOR DAYS (more on this later) The gist of it is there are a million settings, often tucked away after menu UNDER menu UNDER YET ANOTHER menu. Options are in places that don’t make any dang sense. Like seriously just just give me a flat, unified “picture settings” and have all the options under there instead of 5 different settings panes down different nonsensical nested paths. Even better, some settings will silently wipe out your other settings. For example, if you find AI picture settings (which is not in video settings btw) and turn that on it will nuke your current profile’s settings without warning. And then there’s profiles. There are a lot of them, and you can customize them (Game, Standard, Cinema, etc). One thing that wasn’t obvious to me was profiles have different settings available. What I mean by that is you can change some things on “Cinema” that you can’t on “Standard” etc.Bugs on launch firmware:-Tons of flicker issues when using GSYNC with PC. Sometimes the flicker is the “long black” flicker that lands every 30 seconds or so and you get a black frame for ~0.5-1sec every 30 seconds. Then there is the gray static flicker that lands every 5-6 sec and lasts ~0.2-0.4s. The only way I was able to get both to go away was to use “game” mode with ALL filtering, TruMotion, etc set to off. Instant response and deep color on, and in Nvidia control panel make sure you’re using nvidia color settings, color type = RGB (the YC something something settings all caused flicker… and RGB is best anyways), full black level range (not limited!). GSYNC set to “GSYNC Compatible”, low latency mode set to ultra. This took a lot of trial and error on my part with a 2080ti/latest nvidia drivers. Of course I’m plugged direct into the TV and tried multiple HDMI cables. I think it’s finally working now with the above settings *knock on wood*. The system shouldn’t be this fragile!-Optical out audio will sometimes hitch every 15-20 seconds. Because of problems with Apple TV 4K -> receiver -> TV HDMI loop when using Dolby vision (looks like my receiver can’t handle it), I had to go source -> TV -> optical return to receiver. This worked great at first, but the TV will randomly begin hitching where audio will turn off/on for 1-2 sec every 15-20 seconds. Restarting the TV fixes this until it pops up again. NOTE: You must actually turn the TV off, sleep mode doesn’t fix it.-Not really a bug: The default shutdown behavior is “sleep”, and if you have to restart the TV to fix a flicker/sound hitch bug sleep will often not fix it. You need to go into energy settings and tell it to actually shut down when you hit the power button (lol). It’s fine, it boots up super fast anyways.-Instant Response bugs: The TV can get into a loop where the screen will flash, “The Instant Response is on” banner will appear, and then it will flash again and the banner will re-appear. This seemed to be a deal-breaker at first because with instant response off you get a TON of input lag (move mouse, cursor moves wayyy later. Controls feel rubbery). The good news is I was able to work around this by switching to the “game” profile, which leads to the next bug:-Auto power saver profile: The tv seems to want to randomly switch to the auto power saver video profile, and it causes lots of problems. Switch off this profile ASAP and if you have problems see if the TV randomly switched you back to it.[Misc Negatives]-Super invasive anti-privacy features are all on by default. This TV will report on everything you do/content you watch unless you opt out. Personally there’s so much tracking that I’m not giving this thing network access unless I want to update the software.-It’s SUPER thin. Like, half as thick as my iPhone. That’s technologically amazing, but handling this thing honestly spooks me. You really need to baby it setting it up and I was honestly paranoid it’ll crack just lifting the thing even with two people being careful. Imagine lifting a wobbly 90 lb glass mirror that’s half as thick as your phone. It’s kinda like that so make sure you’re spreading it’s own weight out (don’t grab by top corners for example!). I’d love something that I can lift and not worry it’ll crack. Once it’s on the wall who cares how thick the back plate is?-Smart Home features: Maybe this is cool if you want it, but personally I’d never use a TV to run my house. Given the privacy/invasive tracking that is on by default, you’d have to be crazy to hook your whole house up to this IMO. LG: Take a look at how Apple is treating privacy (on device learning, differtial privacy etc). When you start your relationship with the customer trying to track everything they do and making it hard to opt-out they’re not going to trust you when you want to have a hot mic in their living room and automate their toaster. Just my 2c.[Summary]-This is the best TV I have ever owned. The picture is breathtaking, the only thing holding this back is the abysmal software. I’m also super hyped to try 4k120 this fall when the next gen GPUs come out. I’d LOVE to give this a 5/5, and if they patch the software I will certainly return to do so.

    For $1800, you would expect a TV to have a great picture. This one does. It’s worth the price. I am very pleased with the television overall, but have found what I believe is a bug in the software. LG customer service is working on it. However, they have referred the problem to the technical people and haven’t found an answer in the last 10 days. I’m hoping they will soon.The problem is that the television is advertised as being able to connect two bluetooth-capable speakers for true surround sound without any wires. I purchased the two LG-recommended speakers for $200 and discovered when I went to install them that I could only install one on the left (No.1 position). There was no way to select the right (No. 2 position). Furthermore, the one that did hook up had virtually no volume at max setting. When I attempted to increase the volume by using the balance slider between internal and surround sound speakers, it appeared to be inoperative.Getting true surround sound wasn’t the primary reason I purchased an OLED television. It was, however, the thing that made me decide to bite the bullet and upgrade to the best tv on the market. I hope they have this problem fixed quickly.7/2/2020 Revised ReviewLG sent out a new software update today. My problem with the surround sound has been resolved. The functions that weren’t working have been fixed and the sound is beautiful. The screen where you pair the speakers now has icons that show which speaker is right and which left. I did not see anything that showed that when I was struggling with it.I can enthusiastically say that this is the best TV on the market today.

    Updated review (10/13/2020)Mounting was a breeze. Took about 10 minutes to screw the mount into the back of the TV. Most of that time was ensuring that I attached to the desired holes on the mount, as the mount supported attaching the TV at multiple locations. It does take 2 people to mount. I don’t care how strong you think you are. It’s not a weight issue so much as it’s a wingspan issue. The required placement of your hands, so you don’t damage the EXTREMELY thin screen, doesn’t allow for only holding the entire TV with 2 hands. I solicited the help of my visiting in-law. We picked it up, hooked the mount to the wall and presto we were done. Plugged in the power and cables and ready to watch.Recommendation: Pay the extra money and get an AC outlet directly behind the TV. They sell power cable in-wall kits that don’t require an electrician and I’m sure those work just as well. Basically those are just cable routing outlets that allow you to use an electrical extender to bring power from the outlet behind your ground-level furniture thru the wall up to the extension “outlet”. It’s cool because it’s really just a fancy extension cord so you aren’t faced with the cost of an electrician to install a new outlet. Point is…get an extender or a new outlet. Either way you’re not going to want to see cables dangling down the wall after mounting your beautiful, expensive TV. I had to get a real outlet installed because the wall I mounted on was an outdoor perimeter wall, so the thickness between the dry wall and the concrete block left about 1.25 inches of space. My electrician had to feed the cables thru the wall until his hands were bleeding (better him than me) as the space was so small. The wall mount had to be drilled thru the drywall directly into the concrete also. Upside, that TV is never falling off the wall. I could hang 10 TVs off that mount. I jest.Also I bought an LED strip that is stuck to the back of the TV. It plugs directly into the USB input on the back of the TV so it turns on/off with the TV. You can change the colors but I just go with a soft white and it really compliments the TV and provides an outer glow which can be seen in my attached photos.Original review…Everyone talks about the amazing picture quality so I won’t bother with that. Let’s just say it’s incredible.Something that really impressed me is the thickness of the actual screen. It’s thinner than my iPhone X. The “downside” to the screen being this thin is when we lifted it I was concerned about applying too much pressure and potentially causing damage as it flexed. The instructions discuss how to hold the TV when lifting it whereas most of the pressure is actually to the bottom half of the TV so it isn’t really a problem but something to be cognizant of.It’s easy to access all the inputs/outputs on the back. 4 of the HMDI ports are actually on the left side (facing the TV). The power cord is on the right side, although rear facing. That’s not a complaint, I just want to provide that information.Setup couldn’t be easier. I had my cable box connected thru HDMI and my PS4 connected thru HDMI as well. Then I turned on the TV for the first time. Over the course of a few minutes the TV detected everything that was plugged in and asked a question “are these the correct components plugged in?” Aside from providing the wifi password I didn’t have to get involved in the setup at all. After everything was setup I plugged in my Bose Soundbar. I tried using the HDMI eArc plug which failed as it always has (same lack of success on my previous TV). I’ve come to the conclusion that the only way to get the Bose Soundbar to work is thru the optical cable, and I don’t put the blame on LG. That is certainly a Bose shortcoming. Regardless, I plugged it in thru the optical port. You have to navigate to the “All Settings” menu thru the TV to the sound settings. There is a selection to use Optical, TV, Both, etc. When I made the correct choice it worked as expected.The TV also comes with an over the air LG TV service. That was completely unexpected. I confused that with the cable provided by my Spectrum cable box. Once I realized what was happening I was pleasantly excited. I don’t know if I will use it, but considering the cost of cable it is something I will investigate further.We had the Amazon Fire TV on our older TV and don’t need it anymore on this new TV. All those same services that we use, Netflix, Amazon Prime, Apple TV, Disney Plus and Hulu are built in. As expected an enormous number of other services are also available. That is very convenient.In conclusion I recommend this TV purchase with zero hesitation.
