Q: Are current LG OLED TVs less susceptible to screen burn-in than earlier models? I am replacing a 2016 model that developed burn-in of the CNN logo. I’d love to get a new OLED, but I’m afraid burn-in will reoccur. Would I be better off with a QLED set?

A: OLEDS are still susceptible to burn in. It’s just the nature of the rechnology. However, the new models have features that make it less likely. LG models now have screen shift which constantly moves the screen a few pixels and logo luminance adjustment which dims static images like logos. You can also avoid burnin by varying what you watch. Especially news programs with static logos. Particularly red logos. According to a popular tv rating website the CNN logo is the number one cause of OLED burn in. If burn in happens under warranty LG will cover parts to repair it but not labor. You can also purchase Geek Squad coversge which covers parts and labor but in some cases just offers a replacement. That’s how I got my C7 replaced after burn in of the CNN logo. The CX is my fourth Lg OLED. Only had burn in on the one and since then I watch cable news on my computer or the kitchen tv just to be safe. As for QLED vs OLED....burn in does not happen with QLED. If you watch a lot of CNN or just tend to leave it on all the time I would by the QLED. They both produce excellent pictures but have different qualities. I watch a lot of movies and play video games so I stick with OLED for color accuracy, viewing in a dark room and response time. Qled is very good in those areas but in my opinion the OLED is better. Hope my answer helps.....

Q: Reflection, Glare and Brightness, Burn in. How concerned should I be about this? Samsung for 13 years zero issues with the TV. I am debating LG CX 55 or Samsung Q90t. I assume people watch their OLED during the day or morning right? I want to switch but..

A: Hi James, I went with the cx...spent 2 weeks with it trying to love it. I have an average bright room and it’s dim during the day. It’s really dim with HDR content as well. The blacks I kept hearing about are nice but when the whole screen is black was hard to see anything. Otherwise aside from way too many setting it was okay but it just doesn’t get bright enough like 750 nits max. Exchanged for a Q90T....wow the bright vibrant picture, 4K upscale was better, sports during the day were way better. HRD better as it can do way more brightness which is the whole point of HDR. I wanted to like OLED and maybe if I watched tv in a cave I would have but I like to have my blinds open and even at night have lamps on. And I don’t to baby sit my tv either burn is rare but until it’s covered by LG it’s probably something to be aware of. OLED people will bash QLED and vice versa I’ve had both and they both have their pros and cons. In terms of usable tv in all environments and different people in a room with varied light a QLED is just a more pleasing TV.

Q: Is it normal for the screen to have a bluish tint when the tv is off?

A: The slight purplish tint that you see on the LG CX 55 inch Class 4K Smart OLED TV w/ AI ThinQ® (54.6'' Diag), Model # OLED55CXPUA is normal. That is the anti-reflective coating that is common in among high-end TVs...^IFV

Q: Does this tv support ARC or eARC?

A: it supports both!

Q: Does this have a ATSC 3.0 receiver ( next gen) My market ( Baltimore) will have 3.0 available in July and I use an indoor antenna for OTA channels. I am starting to shop for a tv which can use that technology. Thanks..

A: The LG CX 55 inch Class 4K Smart OLED TV w/ AI ThinQ® (54.6'' Diag), Model # OLED55CXPUA does not have a NEXTGEN TV (ATSC 3.0) tuner. The six 2020 LG OLED models that have built-in hardware to support the NEXTGEN TV (ATSC 3.0) tuner are: the 55-, 65- and 77-inch class GX Gallery Series 4K Ultra HD models, the 65-inch class WX Wallpaper 4K model and 77- and 88-inch class ZX Real 8K models. These models will receive a firmware update that is required to activate the tuner which will automatically be pushed out later this year. This will be a staged rollout and as you have mentioned, it will be rolled out when your market begins NEXTGEN services...^IFV

Q: What is the actual difference between the c9 and the XX and do it justify the price difference?

A: Whether the difference is justified is in the eye of the beholder - value judgements are that, value judgements. Extras the CX has: Dolby Vision IQ New upscaler and picture AI (i have no idea how much better, it is i only have the CX) FreeSync ALLM (Auto Low Latency Mode) α9 Gen 3 AI Processor 4K AI Sound Pro
