42" OLED MASTER THREAD

Does anyone know if dimming/ABSL issues were fixed in C3/C4? I hear mixed reports that a firmware update mostly fixed it. There is a "workaround" that was posted on youtube, but it doesn't look practical (puts your screen in factory mode permanently, seems like a giant PITA).
 
I just picked up a 42” LG C4 yesterday. First time using an OLED as a PC monitor and so far I’m very impressed. If anyone wants to do check anything let me know.

Or by using the software solution (which might only bring back the original service menu)?

As long as there is a solution then I'm fine with it. I'm keeping my options open because there are more reports of the MSI QD-OLEDs randomly turning themselves off mid game and while it has only happened to me once so far, I cannot rule out that it won't happen again sometime in the future. And unless MSI acknowledges the issue and promises to fix it, I may just have to look elsewhere for a replacement display and I'm not going to bother getting another QD-OLED because only HDR TB400 mode is useable to me and it has crappy peak brightness of just 460 nits, while the WOLED monitors are matte. That leaves me with the 42 C4 as the only potential replacement display, I'm fine with dropping down from 240Hz to 144Hz if it means getting better HDR, a glossy finish, and having a screen that doesn't decide to randomly turn off on me mid game and cost me a win.

Damn man you'd really take the 240 to 144hz hit that easy. I think it's the QD-OLED's biggest selling point.

I wonder what the state of the PG42UQ is now. It will still be brighter than the C4 (basically 2x as bright in content on 10% window vs QD-OLED) and only down 6hz while avoiding all the TV crap. Matte though.

No game I'm playing atm actually runs close to 240fps though (currently playing a lot of Helldivers 2 and that only gets 110fps with a 7800X3D and 4090 at 4K), and looking into the future I don't think that's going to change, I'm expecting to get no more than 144fps in pretty much all titles that are going to come out this year so there's not much point to 240Hz if I can't get the fps to make use of it. I did enjoy the hell out of my QD-OLED when I was briefly into The Finals and I got around 180-200fps in that game, but I've gotten kinda bored of it now. Anyways, there were people who were willing to go from a 240Hz OLED all the way down to a 120Hz VA with the Samsung G9 so by comparison, this isn't that bad of a drop lol. I'm also not going to bother switching as long as my QD-OLED behaves itself.

Yeah I have the same thinking. Most I ever see in the games I play is 160FPS. Having 240hz really only benefits me on the desktop and some random indie title that can run on a potato.
 
I'm also already going back and fourth between a 240Hz OLED and a piss slow 144Hz IPS (InnoCN 32M2V) so I guess going to a 144Hz OLED isn't as jarring.
 
Same experience for me in the few days I had my 240Hz Alienware. Every game I played was around ~120 FPS (with ultra settings/ray tracing where possible) so I was wondering what the point of downsizing from 120Hz 48" to 240Hz 32" was. I'm guessing this will change though with the 5090.
 
It should be noted that a 240 hz display set to 240 hz would always be 240 hz regardless of the FPS. Might be marginal gains though.
 
So The Display Guy in his latest video says he disabled dimming on the C4. And that that was necessary to do. He doesn't go into details on that procedure though...

Part of why the advanced BFI on the CX/C1 is so great.

To me it's just headroom. I'm currently playing Like A Dragon Infinite Wealth and on my 4090 that runs at 4K 120 fps with Nvidia DLAA. I could probably push it quite a bit further with DLSS and FG but what's the point if your display can't show those frames?

To be fair for anything but the most fast paced games, 120 fps is more than good enough and it's increasingly diminishing returns from there IMO. I just like having the headroom in the happy case that is possible without severe compromises.
 
Funny enough I just ran the FF14 Dawntrail benchmark. With 4K maximum settings I got 130fps, but after switching DLSS to "Always ON", my fps jumped to 210. I do plan to sink in a ton of hours into Dawntrail when it comes out so I guess the full 240Hz will finally be used again lol.
 
@thedisplayguy responded.

Q: "Some people are saying that dimming cannot be defeated on the C3 nor the C4 with the service menu. Or that it doesn't stick going right back to dimming when you cycle the power on these screens. Can you please confirm one way or the other?"

A: "I disabled it with a Windows program."

Nice, so using ColorControl.

Just for some confirmation on this issue, were you ever able to use ControlControl and to off ASBL on 42C4? Or found any actual proof?

I tried a bunch of the new 32" 4K oled monitors and they all have some kind of various annoying issue I'd rather not deal with and still overall still prefer my old 42C2 (much to even my disbelief, starting to call this thing "old trusty"). So I've decided to try use my geeksquad plan to upgrade my 42C2 to a 42C4 this fall when the price drops for an equal exchange. But I'd be on the fence if ABSL can't be turned off on the C4 like how I easily turned it off on the C2.

I never disabled the ASBL on the 42c2 nor on the 55c7. It only happens during desktop use such as browsing, and never in games or movies playback. Actually, it did dim in movie playback at first, and I really didn't like that and thought this C2 was kind of broken unless I play games on it, thankfully I don't watch much movies on the desktop and use it solely for gaming and browsing probably 99% of the time, but after certain firmware update the dimming in movies stopped completely. So now it dims only in desktop use, which I find not bothering, I even find it rather a comfort feature, it eases off on the eyes when it reduces the luminance and I know it prolongs lifespan of the display and also reduces electricity consumption. So much good stuff the ASBL provides, when you come to think of it. Really, a neat feature.
 
Okay according to someone on reddit it is indeed possible. Awesome.
Yes, it can. But one needs to unlock service menu to full list.

If you want it in full range, use LGTV Companion commands in cmd.exe terminal.
cd /d c:\Program Files\LGTV Companion lgtvcli.exe -settings_other "{"svcMenuFlag": false}"
and then enter the full service menu with 0413 code:
cd /d c:\Program Files\LGTV Companion "LGTV Companion.exe" -button IN_START

From recent reports, it seems there is almost no reason to upgrade to C4. All the big improvements happen in 55" and larger models. The brightness increase is not that noticeable, neither is 24hz. Personally I decided to just keep my 48CX, everything is a compromise and there's no clear upgrade yet for me.

I think a 38" or 42" 240Hz+ oled with 1000+ nits hdr, glossy coating, would be enough to sway me.

True, but this is only if GeekSquad lets me swap. I do have a tiny bit burn in.

Yeah I run my IPS at '20' for brightness, when I'm web browsing or typing in GMAIL, etc. I don't need 400 nits of white screen.

More brightness can be nice on a laptop----while outside.

Or a south facing window office, I suppose.

My work office faces North.

It would have been a decent upgrade if LG didn't decide to nerf the brightness when running in game mode.

This is the 65" version but compared to the 65" C1 it is significantly brighter. I would expect a 42" C4 to be brighter than the C2 by a good margin as well, but once you turn on game mode all of the brightness upgrades go down the drain and the C4 will be no brighter than a CX/C1.
