Incredible picture

Submitted by Rusty17 - 8/2/2019

I purchased last years 65 inch OLED TV and it was great. But when the new 77 inch OLED TVs came out I had to make the upgrade. Best choice I have made in years. The whole family enjoys the large crisp vibrant picture

This TV is an example of what a masterpiece it is.

Submitted by Amrit - 7/22/2019

I bought this TV close to 2 weeks and since then I find every opportunity to watch some content on the TV. The picture quality is amazing deep blacks rich contrast and color tones. Just amazing. HDR is stunning in this TV. I love the Web OS among all other smart TV OS present in the market. Its implementation is really neat and minimalist. I love this TV watching 4K HDR content. Also it has HDMI 2.1 and supports eARC which makes it future proof. I would definitely recommend this TV to anyone who is in market for the OLED.

Big bold and beautiful

Submitted by Matt80525 - 7/17/2019

At 77 this screen is really big and REALLY amazing. My previous TV was a 60 Pioneer Kuro plasma and I could never find an LED TV that could replicate its deep blacks and rich contrast. Enter LG OLED. Im also happy with the Web OS operating system. The built-in speakers are not very good but I cant imagine anyone buying this model without a high-end surround system. Only a few other minor complaints like a universal remote that doesnt have fast-forward/rewind buttons. And the TV has some issues handling new eARC standard default HDMI Auto format setting doesnt work with eARC - hopefully LG will fix this in a firmware update. Also its virtually impossible to get to the input/output panels if you wall mount the TV. Overall you expect a truly amazing TV at this price and the 77 OLED C9 delivers.

Best picture available

Submitted by AlanOnMI - 7/12/2019

I have been using this set for about a month now and I cannot say enough great things about it Size is AWESOME however you pay a BIG price for the 77 screen. I do not have any 4k source material but the upscaling from Blue-Ray DVD and even old 1950s BW TV is fantastic. The user settings for the picture is somewhat convoluted and impossible to understand for the typical home user. Some details on what each of the settings means and how it affects both picture and set life would be greatly appreciated.

Insane lifelike graphics

Submitted by Dustin681 - 7/4/2019

Amazing tv and picture

Submitted by Menedobandido - 6/30/2019

Had my tv for 2 weeks now and love it. The 4K content on it is truly spectacular Its hard to watch regular channels or programming without 4K but even still the HD channels look great. Bought the 5.12 sound bar as well. I think the neighbors down the street know which explosive movie Im watching. Only negative is the remote. Im not a fan of the mouse like remote.

As good as it gets

Submitted by mrsweden - 6/24/2019

Ive only owned this TV for a few weeks but its ridiculously good for watching movies and TV shows. Everything from the setup to mounting it on the wall was easy. The only thing that frustrates me is that even though its running Android the apps available are very limited even many of the most common on demand channels apps like HBO are missing. I was hoping to not need fire sticks or additional boxes with this TV but it appears you still do.

Awesome Screen

Submitted by MEO73 - 6/5/2019

Ive only had this TV for a little over two weeks. My main complaint is that it is so awesome to watch I have a hard time pulling myself away from the TV The screen is phenomenal: colors are dynamic and pop off the screen. Blacks are just thatblack. I watch a fair number of bw films and they are rendered gorgeously on this screen. Its easily the next best thing to sitting in a movie theater. Although some have raised concerns about brightness levels on OLED screens that is simply not a problem. My tv sits about 11 from a large patio door and windows and even in the brightest daylight the screen still displays things perfectly. It is simply without equal in the home video world. The set up and connections were simple. I have a satellite box and 4K DVD player hooked up but spend more time watching Netflix Amazon and Hulu. Switching among them is a breeze. The Magic Remote is fine for what it is. Would be nice if it had dedicated buttons to change the screen aspect ratio with zoom full screen etc and a more fulsome compliment of dvr/dvd type pause ff etc buttons but thats a relatively minor quibble except when watching satellite when they would be handy. I cant speak to the integrated sound system as I have it hooked up to a receiver and speaker array which I suspect most people buying this sort of set would have. With HDMI 2.1 connections a brilliant screen and relative ease of set up and use I cant imagine considering another TV for home use unless you are going the projector route and are willing to live with those limitations. Thus far however I am more than pleased with my purchase.
