    I had been waiting for the new 2020 77” GX OLED since CES in January. Once Best Buy has it in stock I jumped on it. It was nice they included a 400.00 gift card. The tv is super super thin. It comes with a flush mount wall bracket so the tv can hang just like a picture in a art gallery. Hence the “G” in GX... it stands for gallery. I bought all new 8K Ultra High Speed cables to accommodate the 4K @120hz this tv is capable of. Once the Series X and PS5 come out I’ll be able to take full advantage of it. I played a few 4K blu-rays and it looks absolutely amazing. The black levels looks super super inky black. The colors are so vibrant and pop off the screen. It’s by far better than my 2017 E7 OLED I still have. Not that my E7 was bad, but this is a noticeable upgrade. If you want the absolute best of the best. Then this is the tv for you.

    Before my review, here is a quick summary of how I made the decision to buy this particular TV. After doing a bunch of research, I narrowed my search to 77" LG GX and the 65" Sony A90J (both selling for the same price at the time). I went back and forth for a few days but ended up choosing the GX based on how far away we sit from the TV (around 15") and a general consensus that no one ever regrets going bigger. I also took a hard look at the 2021 version of this TV (the G1) but could find only minor differences: slightly newer chipset, "brighter panel", and a new version of WebOS. Although I rarely use WebOS (we almost exclusively stream through an AppleTV), I do appreciate the minimal design of the older version of WebOS included with the GX and the fact that you can turn off the ads. Most importantly, the 2021 G1 was out of my price range and unavailable for purchase. I paid to have the unit wall mounted using the included mount and also had them add power behind the TV. It was well worth the $200 cost. It looks beautiful on the wall and frames the area very well. There is only a minor gap to the wall, maybe a finger-width. Unless you plan on hooking up no wires to the TV (including a power cord), you will most likely have a small gap as well. My previous TV was my 13-year-old Pioneer Elite Kuro 5010 plasma, a top-of-the-line TV at the time which still performed well but had no support for 4K. I can't underestimate what a difference it is going from 50" to 77" and from 1080P to 4K, especially with how far we sit from our TV. We actually sit even farther away when eating dinner in our dining area and the larger TV is a vast improvement. Because we are using the new 4K Apple TV almost 100% of time which defaults to DolbyVision, no calibration was needed. I have it hooked up to the LG SP8YA soundbar and overall, the setup is very simple and clean. In fact, we are able to use the sleek Apple TV remote almost exclusively (unless we want to watch live TV via our HD antenna, which is rare). The picture quality is amazing and I've never felt like the TV wasn't bright enough. In fact, sometimes I feel it is too bright and am tempted to turn the OLED Light settings down. So I'm definitely not regretting my decision to go with the GX instead of the "brighter" G1. I will say, we tend to watch TV in the evenings and have no windows directly facing the TV. As far as features, we don't really use WebOS (since we use our Apple TV for all streaming) so I can't speak to how well it performs. It has Airplay, but I've disabled it since we AirPlay directly to the soundbar (for audio only) or to the AppleTV (audio & video). It also has voice recognition but I found that it was too sensitive, even when adjusting the sensitivity in the settings. Speaking of that, it has a slider bar to adjust sensitivity, but the bar literally only has two positions - all the way to the right or to the left. So it's more like a giant on-off switch than a slider. Hopefully they address that with a firmware update. The only other feature I'm excited to try is the NextGen ATSC 3.0 over-the-air signals when some finally come out in my area, hopefully in late June. Some reviewers may feel differently, but I love the included Magic Remote. I would have no problem using it exclusively if we weren't using the minimal AppleTV remote instead. Overall, I'm very satisfied and would recommend purchasing this TV before they are all gone while the price is so low (and hopefully Best Buy is still including the free $350 gift card w/ purchase). I really don't think the 2021 version is different enough to justify the additional cost and if you plan to use WebOS, the 2020 version of the software would be better for those who prefer minimal design and no ads.

    Awesome TV - Complex Install

    I cannot recommend the LG G series any higher. The picture quality is amazing, 120Hz on the Xbox series x looks amazing, and the finished install is as good as it gets. The install is rather involved as you have to install a recessed box behind the TV, re-route electrical, and I also put some 3/4” plywood reinforcement where the wall mount would attach. It took a fair number of hours to do the install but it was totally worth it for a wall hugging TV. Just an incredible unit. I only wish that the 83” existed when I purchased.

    Fantastic TV, fantastically bad mounting system

    On the display side of this product, it's absolutely fantastic. However, I purchased the GX version of LG's high end 2020 OLED lineup, versus the CX, for two reasons. 1) to get a TV that actually has a full frame and support around the entire display, 2) to get the flush wall mount. The CX has the bulk of the components, and mass, at the bottom as it's built mostly for stand mounting; so you end up with a very flimsy top portion that sits off the wall by several inches, leaving that huge cap, and just asking to be damaged due to the extremely thin upper portion. The GX is one big piece of consistent thickness with chassis/backing behind the entire screen, and then an inset mounting area. So, first things first, read any trusted review of the LG 2020 GX or CX and the display portion of the review is probably accurate, but also all anyone ever tends to cover these displays seems to never touch on the mounting portion of the GX. I don't know if that's because most reviewers would never mount it on the wall if it's temporary, or because they're receiving some benefit, but no one covered this aspect of the GX whatsoever. With that lead in, let's get on to the mounting bracket. It is absolutely horrible. Before I tell you why though, the GX does support a 300x300 VESA mount, but you of course lose the ability to flush mount it, which is why most people buy the GX to begin with. If you're comfortable with an extremely slim-line third party mount, you can still get this puppy pretty close to the wall, but nowhere near as close as with the flush mount. Now, the ridiculous LG flush mount. It could not possibly be designed any worse. It is specifically 16 inches wide, what is hopefully the same as the on-center distance between American building studs your home / apt is constructed with. First issue, the corners of the bracket are thin and not reinforced like other portions of the bracket, and the 77" version of this TV weighs almost 90 pounds. So now what you end up with is a bracket with flimsy corners where the only secure places to mount it (into the studs) are those four weak corners. The best you can do with the other eight holes are drywall anchors... I tried this; rock solid mount into the studs, and it yanked out the top drywall anchors while it deformed around the top two corners with the bracket bending outward while the TV was in the extended position so I could connect the cables. It left me with an extremely uncomfortable feeling when we're talking about $4k hanging on the wall. Issue two; what if you have on-wall/in-wall speakers or an already mounted soundbar related to the TV you're replacing. Well, given this stupid GX bracket is only as wide as two studs, if you didn't mount everything else in a manner that's compatible with the TV being on-center between two studs, now everything is off and you can't move the TV. I ended up having to rip my drywall open, I cut and installed two sections of 2x8 between the studs *extremely* securely. Then I was able to mount the LG recessed mount to the 2x8's with solid screws in every hole position. I could hang on the bracket at this point with zero deflection. Threw the TV up there, and finally was able to cable it and push it into the wall like it was intended. Not all is perfect though... Issue three; the TV seems to be heavier on the rear side. This means if you can't get the mounting bracket to pull the TV into the wall, which is of course impossible, you can't get it to sit truly flush. I pushed the TV flag against the wall, however, the bracket has a little play to it, so it pushes back out just a little bit, and then the bottom angles towards the wall. Not a huge deal, we're talking about 1/8", but still, the LG advertising and promo photos make it look like this thing is glued to the wall, and for $4k that's what I expected. I'll probably end up attaching some hook & loop (don't want to infringe on any trademarks) to the four corners to stick this puppy to the wall and make it look perfect. If you made it through that massive review, the end result is I'm very happy with the display portion of this thing, but not with the eight hours of labor I spent, and two trips to a big box orange home supply store, getting it onto my wall *securely*.

    Fantastic TV, gi-frickin’-normous! Nice bright pic in a very bright room. Lightweight for the size, did not use the included mount, sound quality from built-speakers is extremely good although I went with a Bose 700 sound bar, sub-woofer and wireless surround speakers (which are amazing by the way). I won’t use 90% of the functionality but I would buy this again in a heartbeat. Wishlist? 90” please! This was an upgrade for a Sharp 80” 1080P HD TV (which is still very much in use in the basement with it’s own 5.1 surround setup). Longer term plan is to upgrade that setup with 8K display and PS5 after xmas 21 so as to avoid the first year release issues (and constant software updates) associated with the leading edge. Only one software update so far for this TV fresh out of the box, which should be fully expected for any new connected widget these days. Very happy thus far, I’m not a fan boy of any one particular brand as I research the top products at the time and go. I do not need all the components to be the same brand either as I have a mix of Infinity and Bose speakers, Pioneer Eilte and Denon AV receivers, Amazon Fire, Apple TV, Dish Network and Playstation 2, 3 and 4. I use what works for what I need and am sufficiently technically savvy enough to integrate them together. In the end, do what works for you.

    The only thing I can think to say is wow. Upgraded from a 55 inch TCL 5 series to this beast. The only trouble I had with it is mounting it, it’s not flush just yet but I’m gonna have a professional mount it correctly for me, but other than that, the picture is obviously stunning, and for a TV the sound is superb. There are different sound settings such as AI Pro and Cinema and sometimes you have to play around with it so you can get the best experience for your personal preference. It doesn’t matter if it’s daytime or night, the Tv will perform and it’ll show. I got the 5 year warranty, I plan on having this baby for the long haul. I recommend getting some microfiber cloth to clean it. Finger prints pop up relatively easy. Its the best tv I’ve ever owned, and almost the best I’ve ever seen. The only other TVs that I’ve seen that are better than this are the 20k 8k Oleds and Samsung’s future Microled TVs. If you’re not looking to spending 20k but you’re willing to spend 5-6, and mounted TVs are your thing. This is your TV. If you don’t care for mounts then the 77 CX is also a great choice. Same panel, 1000 dollars cheaper. It was my first choice but my wife wanted liked the design of the GX.

    I purchased a few big screen tv’s over the past year and returned them all. I was worried ablit spening $3500 on this tv and having “buyers remorse”. I have absolutely, unequivocally 0 buyers remorse. The color is amazing , the motion is fluid, the blacks are like a black hole, and elements (fire and water) make you feel them. The operating system is the new OS and is far superior to the operating system of the CX. If like I was, your debating between the CX and GX (and can afford a little extra money) go with the GX. The pictures below are of my actual mounted TV, not stock pictures. And I don’t even have the protective plastic film taken of yet.

    The best picture quality of any TV and the sound is amazing for TV speakers. The only TV that is possibly better is the Sony A90J, but its several thousands more. The only issue are the wall mounting anchors and they are terrible. They don't work. The wall mount is smaller then standard width to mount on studs. I had to mount into one stud and buy special dry wall anchors to support the tv. I uploaded a photo of the drywall anchors i used. At first, i used the anchors that were given and they pretty much came out of the wall. The TV would have fell off if I didn't mount onside into a stud.

    Fantastic for watching movies and playing video games. OLED colors pop, and the blacks are truly black. Tv was wall mounted and looks beautiful both on and off. Works best when in a low lighting area. Of all the TVs I have owned, I prefer this remote and Web OS. The apps run smoothly and load quickly and interface is by far, one of the easiest to use and navigate. Almost all of the apps and streaming services are available when I set up the TV, except for the Tennis Channel.

    Amazing TV…Ungodly Mount

    Beautiful TV, no bones about it. The picture quality is on a level I’ve never seen before. Deep blacks, vibrant colors and holy cow…the 77” model is HUGE! The GX model is amazing for the ability to flush mount of the wall… HOWEVER the horrible part of this TV…getting it flush mounted. The mount is 16” wide for studs but it doesn’t give you any leeway to adjust the mount to center it on a wall and unless your studs are perfectly centered on the wall where you want the TV, then get ready to open your wall up. After a week I finally had the TV on the wall. I had to open the wall, place/secure 2x8’s to support, insert drywall, mud/tape/sand/paint and then finally got the bracket installed to properly mount it. A word to the wise, make sure to mark the top/bottom of the 2x8’s and then draw the marking line long enough so you’ll know where they’re at. I forgot to do this and had to redo my drywall. Once you got the mount in place, it will take 3 people to get the TV onto the mount. 2 people to lift the TV and one person to spot it until it’s set. It truly is a thing of beauty once it’s flush mounted…can’t even get a finger between the TV & wall. The last photo shows you that the TV is tight to the wall. This is a daunting, time consuming process but the picture quality makes it all worth it!!

    I recently purchased my 77 GX after purchasing a Sony A9G. While the A9G was great, it suffered from audio dropouts via eARC and some bad near black processing. Exchanged for the GX and I’ve been blown away so far. Their new Gen 3 processor is working wonders. The picture quality is out of this world. NO AUDIO DROPOUTS! The near black and dark scenes are being handled superbly. The motion processing is MUCH improved. LG finally got it right with OLED on this set. If you’ve been on the fence, it’s time to hop in because the 2020 GX is the KING

    Amazing picture quality, AI features, LG channels. This TV can do many things with all the features it offers. It even has full selection of wall hangings w/ digital frames that look like real paintings, or you can ad your own images. Geek squad came out, delivered, set-up all components, and did an in-wall installation. Very clean install, asked my opinion about placement, walked through all TV settings, and did a full cleanup. WELL worth it to have them do the installation! You can't go wrong with this TV & Geek Squad!

    Mounted on the wall, it looks like a piece of art. I used different tapcon concrete screws to install the included frame, and installation wasn't too difficult however it would have been nice to have a paper guide that was the exact size of the TV. When mounted to the wall, it is flush and I used a cable management system to hide the cables for a clean look. The speakers are "ok" but don't use them since I run this thru a Sonos Arc with sub and rears which complement this tv beautifully

    I bought this TV about 2 months ago for my bedroom and so far, I’m impressed. I have a very large master bedroom and I had a 65 inch and it was not large enough. The picture color is good and I haven’t had any issues. I don’t use the tv sound because I use Sonos speakers and have a Sonos play bar on the TV. I do recommend you use a play bar because the sound is mediocre. I would recommend this television.

The template provided for the installation was a waste of time, don't bother - use painter's tape as you measure the wall to figure out the dimensions. I don't use the interface as we use Roku.
