Direct Sunlight on TV

[darkerice]

Hi,
I really need some advice on TV and Sunlight. Back in 2018 I bought an LG OLED B series (2017) model. A few years ago I noticed some image retention but it would eventually go away. However, this year I am now seeing legit burn in. On Yellow, Red, and Purple screens especially I can see color banding in the center of the screen, I see an old image of a video game scoreboard in the top, and I also see the NETFLIX logo engraved in the bottom right. When the screen is fully white, you can't see it its only when those colors are on screen. Yellow color looks greenish and Purple looks a bit blue in the middle.

I never used my TV that much and NETFLIX was occassional. I am in full belief that these images got stuck because the TV is in a room that gets too much sunlight. Am I right?

My upstairs family room has a WEST Facing Window, so in the summertime and most evenings it gets a lot of sunlight. Even with the TV on the south wall, I think enough rays hit it which caused the OLED pixels to degrade.

I used to have a LED TV up here for years and never had the issue. Would I get this issue with a Samsung QLED? We need a TV in this room and the south wall is the only one that can accept a TV.

The reason you don't see it when the screen is white is because LG's OLED is actually RGBW (meaning there is a white subpixel source as well). The burn-in is on the RGB subpixels. Your belief of the direct/sunlight is only partially true. Due to the sunlight in the room, the TV probably has it's brightness levels almost maxed out as OLED is not as bright as LED-LCD or even older plasma TVs. Due to running so bright, they will be damaged more quickly.

A QLED will not suffer the same problems as it is a LED-LCD with quantum dots. LCD's do not suffer burn-in (OLED does suffer burn-in as the organics in the LED degrade over time and degrade faster in higher temperatures, typically due to higher brightness).

Try running the pixel refresher overnight. Also, if the TV is switched off from the mains instead of letting it sleep, it won't be able to refresh the pixels while it's off. It makes a slight whirring sound while in sleep mode when it's doing the pixel refreshing/scrubbing.

I bought the exact same TV around the same time and have exactly the same issue. It's placed in a very bright room with large french doors and a very big roof lantern above. The late afternoon and evening sun shines through the doors and hits part of the screen for a period of time. Like you, I have the same Netflix logo bottom-right and other feint text top left. I think those might have been after a sleepover my son had with some friends and it may have been left on all night. Also, the overall colour is completely ruined with skin tones now taking on a green hue - we call it the Spock effect! It's now bad enough that I need to look for a replacement.

I'd be interested to know whether you went with QLED, and if so how it has performed.

Depending on your budget, I would look at the Sony Bravia 9. As it is MiniLED LCD with quantum dots, it will not suffer burn in (only image retention which can be fixed). Only reason I have not purchased one is because it only has 2 HDMI 2.1 ports and I need 3 right now, and possibly 4 in the very near future.

Thanks, I'll check it out. Not sure I'll need many HDMIs, one for Sonos and maybe one for a streamer. What's the benefit of 1.2?

The HDMI 2.1 ports are the ones that support full 4k 4:4:4 color with HDR and up to 120hz refresh (not all 2.1 ports will support things like variable refresh rate, auto-low latency mode, eARC, and a fixed rate link, as they made all these things "optional", but they are the only reason for having HDMI 2.1 in the first place and are anything but optional if you want to be able to use it properly, and are one of the items that the TV manufacturers screw up on disclosing the support and it takes until a compatent review site goes and tests a production model that we find out what is really supported). Most of the optional features are things that make the TV better for use with gaming consoles or computers, as well as for interconnecting with audio systems.

Most people can probably get by with just 2 HDMI 2.1 ports, but at this point, the flagship TV's (which the Bravia 9 is) should now have all ports be HDMI 2.1. Unfortunately most of the TV manufacturers have been reserving this only for their 8k TVs (as the HDMI 2.1 is required for 8k content). Very few source devices use HDMI 2.1, PS5, Xbox Series X, computers with a current generation or possibly 1 previous generation graphics card, and just a very select few cable boxes (I believe comcast has 3 models). I have a PS5, a home theater PC, and the cable box from comcast (so I have 3 devices right now, and people suspect the new Nintendo console will also have HDMI 2.1).
