    OLED Is King, and LG Sits on the Throne!
    5 out of 5 stars
    OLED Is King, and LG Sits on the Throne!
    I've been considering an OLED purchase for years - and now that 4k content is readily available, I finally decided it was time to upgrade. I went with the LG OLED because in every professional rating/test proves LG OLED panels perform above and beyond the competition. I upgraded from a 55" Panasonic Plasma to the 65" LG C8. Those of you who are true videophiles know that plasma was a fantastic technology that got a bad rap. Plasma had tremendous, deep blacks, with a great picture. My plasma was a 2012 model, however, and was not 4k capable. I said I'd wait until 4k content was widely available before upgrading. Well, Amazon Prime Video, Netflix, and my Xfinity Cable all offer 4k content - so it was time! Straight out of the box, you’ll want to disable the “soap opera” settings (TruMotion). For the life of me, I don’t know why TV manufactures are still using this technology. It looks terrible. However, once this feature is disabled, and the rest of the picture tuning is completed, you’ll want to cry because you never knew a TV picture could look so incredible. Seriously, I knew OLED to be awesome, but I did not know it could possibly be THIS awesome. The picture is simply stunning. Goosebumps-stunning. I keep the OLED panel light set around 25-30 most of the time. At first, it may seem dim, but after a day or two of watching TV, it becomes very natural. The super-bright OLED is not good for your eyes, and it is not good at accurately recreating a picture. In my setup, with dark navy walls behind the TV, when the lights are out, you can't differentiate the wall from the TV - the blacks are simply that "black". The content appears to come straight out of the wall. The crisp, natural look is impossible to describe here - just know that you can't find a better picture anywhere. I just can’t get over how amazing the picture looks. Other findings: - The Smart features are amazing. I can turn the TV on and off by voice with my Google Home setup. I believe it works the same with Alexa. The TV features a plethora of apps through WebOS (including several you can download for free). It is incredibly easy to cast content from phones, computers, etc. - The remote is also awesome - it works like a mouse - so even the built-in web browser is very, very easy to use. I can visit/use any website with ease through the TV. Navigating through menus is also very easy. The remote took a little getting used to, but after using it for a short period of time, it began to feel very natural. - I've only heard the built-in speakers a few times since I use a full 5.1 channel home theater setup. They are robust, to say the least, but they can never replicate a full home theater setup. Not “negatives” per se, but, considerations: - Mounting the TV on the wall was perhaps the most nerve-racking experience of my life. This is a $3,000 TV, yet, the upper 75% of the TV is nearly as thin as a paper, and just about as flexible. To attach the mounts, I had to lay the TV down on the ground flat. The mounts attached easily – but lifting the TV off the ground was the worst part, because all the weight and structure is in the base of the TV. You simply cannot lift the TV from the top corners, or you'll risk (literally) shattering the panel. They even include a warning about holding/lifting from the top corners. It took a lot of strength to lift it off the ground using the mount arms/bottom of the TV - but once it was upright, it felt very sturdy. - I was equally frustrated by the exceptionally short power cable. It is maybe 36"? Just enough to reach the ground after mounting it on the wall. I had to run an extension cord just to plug it in. For $3,000, it would've been nice to toss in an extra two or three feet of power cable, right? - One warning - if you run the pixel wiper (takes an hour or so), beware that the TV will turn itself ON after it is done. So, don't start the wipe and leave for work or go to bed - you may end up with burn in. (Burn in has not happened to me - I am as OCD as it gets when to making sure it is off when I'm not watching it, and not on the same channel w/ scrolling banners, etc.) OLED burn-in is a real thing, though, so just be careful when watching certain content. Gamers and those who only watch cable news channels should probably consider a different technology. I did elect to purchase the SquareTrade extended warranty. Considering the expense of this TV, I love having that piece of mind for the next four years, should something go wrong. All-in-all, I couldn’t be happier. This is the TV I’ve been dreaming of. If you move forward and purchase, you’ll agree! IMPORTANT NOTE: Take with a grain of salt those reviewers who rate this TV badly because of burn-in. The burn-in is almost always caused by lack of awareness and/or carelessness by the reviewer; if the TV is left on a static image/channel for way too long, it’s going to burn in (as any TV can do – plasma, LED, and OLED). That is not the fault of the manufacture; that is the fault of the user.

      I did a lot of research before buying a TV, and picked this one to replace my aging 1080p set. (I should note that my old TV cost something like $6,000, so it was extremely nice, but it was also 1080p and more than 10 years old.)

      This LG model has worked beautifully. With some minor picture adjustments (look it up—basically turn off the motion smoothing and the rest of it is great right out of the box), it looked fantastic and has performed well from day 1. I also appreciated its ability to pass audio back to my receiver over HDMI, which works reliably even when changing inputs. This means I don't have to touch the receiver when I change inputs, which I used to have to do. Fewer remotes? Total win.

      The HDR features work great attached to an Apple TV 4K, and I have been blown away by the picture quality. Especially when playing back older content (I still watch a lot of standard definition video, on DVDs and stuff), the set looks terrific and the viewing angle for all content is kind of amazing—you can sit off the side and not see any color/brightness shift. This makes it the ideal set for a viewing party.

      If you're ever worried about OLED burn-in, check out the built-in pixel refresher. Basically it does a one-hour-ish cleaning cycle after you activate it (which turns the TV off, and the TV must remain off until it's done—or you have to do it over again). I use subtitles on almost all programming (so hard black/white in the same bottom region of the screen) and have not seen any burn-in in months of heavy use. I ran the refresher once just to see what it would do. I couldn't tell the difference, but it...felt nice to have that option I guess?

      I don't use the smart features at all, so I can't comment on them. I can say the WebOS interface seems fine for getting at the settings and stuff.

      The one negative I can say about this is the red pointer that shows up when you use the remote. My cat thinks it's a laser toy and runs straight for the TV, trying to catch the red dot. So...yeah, just be careful about that one. We try to turn the set on and off using a different remote, and only use the actual TV's remote when we absolutely have to, because that cat is a monster.

      Perfect blacks
      No edge bleeding

      HDR Netflix looks insanely good
      UI is snappy and fast
      Long base stand blocks unsightful cables from being seen.
      Very bright whites; kind of hurt my eyes.

      I setup and installed this by myself. With some careful planning, it can be done. I was skeptical at first after reading other people’s stories about burn-in issues. I put the LG logo dimming seting on high; it doesn’t effect the quality.

      I still use bias lighting to ease eye strain. I have the led string plugged into the TV USB port. Powering off the TV will not automatically shutoff power to the USB port if pixel refresh is scheduled.

      Slight banding when looking at dark gray. Don’t see it during normal viewing. Better than flashlighting or edge bleed though by far.

      I do have to babysit this TV. Have to be cautious of watching the news or falling asleep with my Xbox menu sitting there.

      Update (2019): After six months of use. No issues with burn in. Very happy with this TV.

      Update (2021): After 2.5 years the TV has a large green blob in the middle of the screen. Apparently its due to the processor and motherboard on the backside overheating and damaging the panel. I did everything I could to keep this TV from getting "burned-in" but this type of damage is unavoidable! Cannot watch anything without getting annoyed and distracted. Was hoping this would last at least 7 years, but no matter how much you care for the product, it's inevitable IT WILL get a green blob.

      Avoid LG customer service! They give you the run around and blame you for issues when it’s clearly a flaw in the way the TVs are designed. Not to mention it’s near impossible to understand anything they are saying! Great TVs (under warranty period) but go bad immediately thereafter. Expect more for a 2k price tag!

      Reviewed in Canada on January 30, 2020
      The "TV" part of the LG C8 Smart TV is very decent. I personally experienced some vertical banding but it's only noticeable when viewing dark grey non-HDR content, so in my experience it only really shows on apps splash screens. Otherwise I'm very happy with the picture quality.

      The "Smart" part, however, is such an annoying mess that I can't help but rate this garbage one star. This thing has the WORST wi-fi antenna I have ever seen. It makes the PS4 wi-fi seem reliable. I have 11 other devices in the house, many of them further from the router than the TV, and none of them have any trouble connecting to the wi-fi, yet the TV constantly drops connection, fails to connect to the internet, slows down to a crawl or forgets the network or my password. The apps themselves are pretty good, but they don't work 90% of the time because the wi-fi is such garbage. "Make sure you have a working internet connection", well screw you, C8, my PS4, my switch, my laptop, my desktop, my tablet, me phone, my roommate's Alexa, personal phone, work phone and laptop can all connect just fine.

      Garbage.
