Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

No DTS support so I get no audio for some movies

Xavy 5/9/2022

This TV does not have DTS or DTS passthrough so even if you buy a receiver with DTS there will be no audio. The rest of the TV is fine I suppose. I dont know why they are tracking things like what I am watching. All devices are getting too intrusive. The picture quality is very good but the screen is glossy so I get to watch my kitchen during the dark scenes. Put matt finish and give us DTS.

Very disappointed

Lenor mcnaughton 2/14/2022

Not even a year old and mother board went. Costco passed my problem on to LG and my initial contact with the tech has not been favorable. He didnt even know what a pixel was? The last message was the order is in and he will install this week. I still dont even know his name? My initial contact was a response that..why did I call him on his personal cell phone which is a number he gave me..those were the first words to me. I have always had lg and now I am concerned if the tv had this problem..perhaps more are down the line. I much prefer a replacement. I will never purchase a tv from Costco again. I usually do business with Best Buytheir guarantees have always been prompt and equitable. Sorry..I am really a fan of LG..always have been. One more requestif you continue to use Costcothe delivery guys just set the box in my family room..no setup..no taking at least the boxand sure would have appreciated an owners Manuel which was not included.

Mediocre user interface for settings

ACN53 2/10/2022

Setting names and functions of HDMI inputs is confusing and cumbersome. It appears that the HDMI 2port cannot be named. The whole Settings feature needs to be rethought.

Wonderful picture

ManyPlaces 1/29/2022

I have had this TV for several months and enjoy it a lot. The picture quality is excellent. The remote sells the TV with its unique pointer and click select. It has many features that take a while to learn how to drive it. The only issue is that occasionally you have to unplug it to get it to reset and reload. We found this out only by talking to an LG customer service support person by phone.

Beautiful picture

Stingos 1/6/2022

This is the nicest looking TV I have ever purchased. The picture quality is incredible. Im a picture quality purist so being able to set my own settings have the TV keep them is very important to me. Ive had models from other companies in the past that always revert or change my settings on me. Ive never had that problem with this TV. This television is also amazing for gaming. HDMI 2.1 support allows 4K 120 hz or 4K 60 HDR at full RGB. The input response time is lightning quick. Everything about this TV so far has either met or exceeded my expectations. Best television Ive ever purchased.

Great Picture Quality Just ok Software

JohnLGRev 1/1/2022

Right out of the box this is a beautiful TV. It is paper thin and the stand looks clean and low profile. That is before even turning it on. This TV has fantastic picture quality as expected with an OLED display. 4K content with Dolby Vision looks amazing on this thing and its worth the price just for that. I am a little disappointed with the Smart TV software that comes with it. It has a wide range of streaming services and websites like Twitch and YouTube included which is great but occasionally the programs crash. I have to delete my recently used apps for them to work properly again. I continue to receive software updates hoping that each one of them fixes it but the problem still remains after every one. The only other issue is the remote. I like the mouse mechanic that the remote has but after only about 3 months of use the arrow pad in the middle became sticky to click on. I have contacted LG about getting a new one which they promised they would send to me. It has been about 2 months since they said they sent one and I havent gotten it yet. Overall I am happy with my purchase and would buy another LG I just wish the software was fixed so my shows wont crash.

LG 55 Inch OLED TV

Bubstarr 12/26/2021

This TV is by far the best TV that I ever purchased. The colors are rich and full and the display is always realistic and accurate regardless of the broadcast. The controls are friendly and is very easy to negotiate. The apps that are included in the TV are outstanding. LG really out did themselves with this OLED55CXPUA

Zawmer 12/13/2021

I love how the 4K formats look on this TV. My only frustrations are with the quality of the apps software. If I have a PC on the same network that this TV is connected to I should be able to mirror the PCs screen to the TV easily but there doesnt seem to be a way to do that.

Bad Panel

Lg 55 living room 12/7/2021

After last update TV would shut off after a few minutes. Repairman indicated it is a bad panel and will take 3 to 4 weeks to get a replacement panel. I know LG are excellent TVs but the turn around time for this repair is unacceptable.
