I'm guessing he already has the C2 from what he's said though, but i do agree maybe an LCD would be a better fit considering that amount of static work
Assuming you already have the screen, then it probably depends on if you find the dimming from TPC annoying or not during use? Which is your preferred brightness level, the first brightness when it first comes on, or that brightness after it's dimmed? Is is the occasional changing that's the problem?
a few things you can try that will hopefully help:
a few things you can try that will hopefully help:
1. try a different preset mode, Cinema Home is probably a good bet
2. turn on dynamic tone mapping in the brightness menu, that will def help a bit
3. in general > AI menu turn on "AI brightness" as that can help sometimes although i'm not 100% sure if it's designed to work in HDR mode - on the CX I'm pretty sure that's only for DV mode, but then it should help in DV content at least
4. If you really want to, you could just increase the "black level" setting in the brightness menu a couple of notches, that should def help without causing much of an issue for anything
5. OLED near black can be a little tricky to get right, even during a professional hardware calibration it needs a manual shadow detail correction stage to get it right
6. Oh and definitely make sure that within the OLED care menu you have turned ECO mode off, that will only cap your peak brightness
Good write up!It really depends on your usage type and your reason for wanting to turn it off in the first place.
TPC is there to auto dim the screen when it detects there have been limited changes to the APL (Average Picture Level), i.e where there's been static content for a while. On the LG OLED TV's this is quite aggressive. For PC desktop use this can happen quite a lot, I'm currently using the 42C2 and after a couple of minutes it will dim the screen a fair bit. You need to remember though that it doesn't change the fact the image is still static with limited changes to the APL. All it's doing really is reducing the brightness of the OLED pixels in an effort to try and reduce the chance of burn in. The brighter the pixels are operating, the more likely burn in could occur. So the logic being is it will reduce the brightness a bit to try and help.
Really this TPC feature is there with TV usage in mind, after all this is a TV primarily. So it's there for occasions like if you were leaving the TV paused, or away from the screen or something. In that kind of usage, it might as well do that for you to try and help a bit, it's no real concern. The only issue with that for TV usage is that sometimes a scene that is meant to be fairly static, especially common on darker scenes, could trigger this TPC unnecessarily even though it's still a changing and dynamic scene. For tactual dynamic content with any moving image like a TV show, movie, game etc it is really unnecessary to do that and it's not really meant to do it either. It's kicking in when it probably really shouldn't. So for TV usage, that's when some people want to turn it off via the service menu to avoid that distraction.
That's a very good reason to do so, and the only "risk" in that is if you are in the habit of leaving the screen paused or static, it will no longer activate TPC and try and help you a bit. For the actual dynamic content it will have absolutely no risk, as it's just stopping something from activating that shouldn't be activating anyway. If you do disable it you might want to be a little extra careful to not leave it paused or on static screens, but as i said earlier it's still a static image either way - it's just a slightly darker static image with TPC enabled and therefore a bit more risky.
Although having said that you do have to go some to actually cause any real burn in issues on an OLED TV
For PC usage it's a little different and probably more annoying and likely to be experienced. TPC will activate when there's limited APL changes, dropping you from your normal brightness down to a lower level, again to try and help reduce the risk of burn in. But you could achieve the same thing in effect if you just operated the screen at a lower OLED light level (brightness) to start with. TPC will still kick in and dim you even further, but it's not really needed then.
For example (made up approx numbers) if you ran the screen at 100% OLED light level that was operating at 250 nits, when the screen detects static content and an unchanging APL, it might dim you to the equivalent of say 75% OLED light and 180 nits. You could have course instead just run the screen at 75% OLED light level all the time and disable TPC and that would be the equivalent of you always operating in the "safer" mode, if you see what i mean?
If you want to consider turning TPC off, the trick would be to find an OLED light level that is comfortable and appropriate for your static desktop use, and that has a lower chance of burn in. I expect for most people a setting around 50% OLED light giving you a 120 nits approx luminance would be appropriate and comfortable, but you would probably find that's considered a low OLED light level and therefore a safer, less likely to cause burn in, brightness level. Remember that TPC is a safety measure, it has no real link to the actual brightness setting, it just dims the screen when it thinks the content is static for things. If you're operating the screen at a lower OLED light level like that, it's of minimal risk to disable TPC. With TPC enabled i expect what most people end up doing for PC use is setting the screen brighter than they would normally want it, putting up with that for a few minutes, then letting TPC lower you to your comfortable level. That is of course pointless and "worse" from an image retention point of view than just leaving it at the lower level all the time
I don't see there being any real risk in turning TPC off for PC use as long as you're not going to be running at a really bright OLED light level all the time and then leaving the screen really static. There is far more benefit from a burn-in mitigation point of view in being careful with your content, moving things around, hiding task bars, setting screensavers etc than there is in letting a feature like TPC dim you a bit sometimes when it feels like it! And if you're using the screen primarily for its intended usage like gaming, movies, HDR and only a bit for office /static work, it's a really small concern anyway. If you're mainly using it for static/office work, you've probably brought the wrong screen/panel tech to start with!
But..
Thank you sir, and thats awesome to hear!Cheers Mike I’m glad it helped. I’m going to write a guide or make a short video at TFTCentral on this topic, what you need, what to do etc I think as I’m sure it will help others. I’ll include the positioning stuff above too
You’re getting the technologies and terms confused, not helped by the fact they are often interchangeable when people talk about them.Good write up!
You have proving my point what I said.. The C9/CX/C1/C2 users haven't had it long enough to know it doesn't cause long term damage to the OLED TV by turn off ASBL/TPC in the service menu, to backup your theories. The first issue though is ABL kicking in, not ASBL. The power supply on these TVs can't handle every pixel at full brightness at the same time so when a certain amount of the screen gets to be a certain overall brightness level, ABL kicks in and it can't because you disabled ASBL. Both ABL and ASBL are for panel protection for obvious reasons if the image retention protections (such as TPC) in a specific game have constantly dimmed the picture, then this is a clear sign that this game poses a high risk of burn-in. You're playing with fire, don't complain if you get burnt in a few years.
LG informed me that turning off ASBL/TPC in the service menu voids your 5 year warranty if you disabled it for me losing the warranty is the only reason to keep it on. Burn in can happen on modern oleds too if you can't replace the panel just because you disabled an option using the cheap technical remote compare to an Oled price!. You do it at your own risk! If LG discovers this change during panel swap you have a real problem. According to RTINGs you can sort of disable ABL by limiting the brightness settings but that is not compatible with HDR so yeah not applicable, I like how ASBL works and don't find it annoying at all.. I use my OLED for gaming 8hrs and watching Netflix/Disney+ within that time. my gaming light is 25 in a darkroom.
If you was going to write a guide or video on this topic for new users you could at lease wait 5 years or longer and prove it doesn't damage the Oled TV with gaming & streaming at 75% brightness levels to back-up your clam there is no real risk as you said? I am sure RTINGs & HDTVTest wouldn't recommended using a technical remote turning off features that prevent burn-in or damage to the TV do you think Overclockers would put this new thread of yours to a sticky on there forums if there is risk to Oleds without explaining the risks and owners warranty without Pros and Cons of disabling ASBL/TPC.
Yeah they’re never going to say it’s ok of course. But i really doubt any engineer would ever check, and if they ever did they’d never know if you turned something like that back on or did a factory menu reset (which you can do too).
Talk of Vincent, here is his new video. Both great screens, but glad I went with the AlienwareOh and ps, what do you think the first thing is that Vincent at HDTV test does when he gets the new OLED screens?
i understand the video is exaggerating things but holy hell the white uniformity is awwwwwful on his sample....
I don't think I could recommend an OLED for your type of uses to be honest, there's just too much office/static use and for a number of reasons it's not ideal for that (screen size, TPC dimming, text clarity).
Yep. Just get a TN panel and be done with it.
