What people are saying

Rated 5 out of 5 by from No burn in, No dead pixels,no issues, flawless! We've had this set over 4.5 years and works like day one. Colors still pop and everyone who sees it loves the picture and thinness.
Date published: 2020-10-16
Rated 5 out of 5 by from Realibility It's always disheartening to read the bad reviews from people who have gotten the proverbial "lemon" - my feeling is that this happens with all brands. I feel I've gotten an incredible TV. My sister's family in Oregon bought and used this TV for 2 years and opted to move up to the 65". About that time my house burned in Northern Calif and they gifted me with this TV. We carefully packaged it and I drove it to my house and set it up. Since then I've had it on in my house pretty much constantly--especially now with COVID keeping us all home. I've said all this to emphasize that, including the move, it's been well- and even heavily-used with absolutely zero problems - going strong with perfect picture. Lucky? Who really knows - but I'm extremely happy with this TV.

Can the LG 55EF9500 run Wireless Headphones? If so, do they need to be RF, Bluetooth or something else? Any recommended Brands and/or Models of wireless headphones that are proven to work with the LG 55EF9500?

Asked by: WirelessHeadphones
The 55EF9500 connects to bluetooth headsets that support Sound Sync. The HBS-W120's would make a great headset to add to your TV. You can find more information about the headset here: http://www.lg.com/us/bluetooth-headsets-headphones/lg-HBS-W120-tone-studio ^CP

I am looking for a wall tv mount that has a 180 degrees turn. What do you recommend?

Asked by: mp_batera
The LG OLED 4K Smart TV - 55" Class (54.6" Diag), Model # 55EF9500 has an unusual A x B x C VESA Wall Mount Pattern of 200 x 330 x 120 (mm) and the LG Wall Mount Bracket, Model # OTW150 was specifically designed to accommodate this particular Wall Mount Pattern. Regrettably, we are not aware of any VESA Compatible Wall Mounts that will accommodate that pattern other than the LG Wall Mount Bracket. Some Wall Mount manufacturers like Sanus, will have a field on their sites that you can enter the TV's model number to find a compatible wall mount for the TV...^IFV

My amazon app is no longer working after the latest update that I just downloaded. Any ideas on how to get this back up & working?

Asked by: Rayne K
Sign out first, then uninstall it. Turn the TV off and back on. Go to the content store and reinstall the app, sign back in.

How do I allow digital 5.1 out via ARC from the apps? For example, all of the netflix shows with 5.1 dolby digital only comes out as 2 channel stereo. Can I get the TV enabled for AC3?

Asked by: randomdude
I have the same issue. I don't think this TV outputs 5.1 which is really strange. Best bet is to get a 5.1 receiver.
