LG 48CX

Can anyone confirm that there is still no way - no secret menu setting or magic workaround - to configure an LG CX to power on and off with the presence of HDMI signal like a computer monitor.?

If you enable voice on the LG remote you can hold the mic button down and tell it to "turn off the screen". This turns off the emitters without dropping the screen/monitor functionality at all which is especially useful for multi monitor setups. Even with a single screen it will leave a full screen exclusive HDR game running "in the background" with the screen off. You can still hear the sound running if you don't mute it separately. Clicking any button on the remote, for example just hitting one side of the wheel button, will instantly turn the emitters back on. This is very useful for randomly leaving your desk/screen to go to the bathroom or go talk to someone or look something up, pick up a package or whatever that always has the potential to take longer than you expected due to the task taking longer or getting sidetracked and forgetting that you left the screen on. This doesn't put the monitor functions into standby though so it's still best to turn the screen off using the power button at least overnight or when going out an extended period of time. Once the screen is off for quite awhile, it will sometimes go into an OLED wear evening routine for maitenance so you don't want to leave it on 24/7 even if using the "turn off the screen" trick.


According to the nvidia viewing angle/distance calculator, the nearest you can sit to a 48" 4k screen and still be in the 20/20 vision threshold is 33.5", but I feel like 38" to 48" is best for this screen personally. Any closer than 33.5" and you will get much worse aliasing on graphics and subsampling/aliasing on text. Your viewing angle will also be bad.

For a 50" screen the nearest you can sit within the 20/20 vision threshold is 38.5" away (which has a 64 deg viewing angle, 60 PPD ). Any closer than that 20/20 vision threshold = much worse aliasing on graphics and subsampling/aliasing on text.

In my opinion you'd be better off viewing a little farther to get better PPD and in order to see more of the screen comfortably with a narrower viewing angle.
58deg viewing angle (43" viewing distance to a 55" screen, 66 PPD)
to
47 degree viewing angle(55" viewing distance to a 55" screen, 81.7 PPD)

--------------------------

I think a 55" would work for someone with the space to view it as described above.. especially if you had a desk on wheels or you were using a controller or driving wheel floor stand so that you could move your sitting distance depending on what you were watching/playing. I considered the 55" when it was on sale on black friday actually. The problem I'd have with a 55" is that it would push my side monitor(s) a little farther away to the sides which would probably require me to sit farther away and then I'd probably have to bump up the scaling a notch on the side monitor(s). For letterboxed HDR material or even playing 21:9 or 21:10 resolution uw gaming on the screens it might be better to go larger but again that depends on how near or far you are able to sit to the screens. It's all relative to viewing distance.

Wow. Thank you for that write up! I like the 55" lmfao

You can try if the latest version of ColorControl can do it with wake on LAN. I don't find having to push a button on the remote much of a chore.
 
Oof, so I got my brand new 48" LG CX and promptly tipped it over on my desk during setup. My GF's thumb and a power cable seem to have broken its fall. Pure negligence, but.. the panel appears to be undamaged. In fact, it's perfect. Zero dead pixels, no banding, etc. I've been using it for the past couple weeks and it's been issue-free. Do you all think I'm good to go? I'm just worried something broke internally that I'm just not seeing yet.

If you’re worried get the extended warranty. But, if you haven’t seen an issue yet you’re probably good to go. Take care of that girl, yo.:)

Yeah I feel like a complete idiot about it. I have the 5 year BB standard warranty to cover burn-in, but obviously I would like to avoid having to use it later on down the road. I'm also within my 45 day return window (pro elite plus account or whatever with BB), so I'm weighing the risk of playing the panel lottery and letting go of a basically perfect panel because of an incredibly dumb mistake on my part.

If it ain't broke... There isn't much inside you can break. You are really lucky you didn't shatter the screen though, it's a thin, large piece of glass. I would not worry about it if you don't see any damage. These screens are fragile, moreso than normal monitors. They scratch pretty easy too, as I discovered a while ago by accident. I accidentally tapped the screen with an HDMI connector while plugging things in, and it left a small permanent mark. I think they are intended to be many meters away from anyone waving stuff around.

Click to expand...
Sooner than that I think. I believe April is when it's been reported they'll be available. It's basically the same panel as CX, it seems like it won't even have higher HDR brightness. So all you're getting is the faster processor. Seems like a minimal upgrade. Given rumors of 20% price drop, that means the CX should be really cheap in the next month or two, probably 1-1.2k new. The 48 C1 may be produced in a new factory, hopefully that doesn't impact panel quality.

Oh wow wasn't expecting that. I'll wait a bit more to install it though (probably not even available in Europe yet).

Although I'm not sure yet how this will compare to manual calibration for a small framerate range like I am doing now.

Since we can only have one single "Game" profile, having a simple toggle would be most welcome so that I would leave it off most of the time and turn it on only for 60ish fps games.

First pixel issue with my CX55 after less than a year of ownership. My C9 65 is a year older and doesn't have any dead or stuck pixels that I've seen yet. Thankfully it's in the top of the screen and this is used as a monitor so I'll likely never notice it. Going to run pixel refresher to see if it can be fixed but assuming it's a dead pixel and probably not.
 
What do you guys think is the optimal size for a secondary display to the side of the 48 CX? Portrait or Landscape?

Depends what you mean by "secondary". If you mean "screens for discord, browser window, etc. while a game is on the OLED", yeah portrait. If you mean a screen you use for everything while not gaming because you're worried about static stuff on the OLED, a 32" landscape.
 
new fw 03.21.18 is up on OTA and LG website

1. Improvement
1) VRR Raised near black
=> The new 'Fine Tune Dark Areas' feature, which was added to 2021 and 2020 OLED TVs' menu, will help customers adjust dark areas, which can mitigate some of the raised near black effects customers have experienced.
The feature is available in Picture > Additional Settings > Fine Tune Dark Areas (2020 TVs) and General > Game Optimizer > Fine Tune Dark Areas (2021 TVs)
2) iTV App playback error (in the UK)
=> There were cases where videos looped to play automatically, when interrupted by ads, stopped the automatic play.
The bug has been fixed.

Ah bummer. I think this is not uncommon though. It's just a single pixel I assume? I think sometimes they come back too. So I wouldn't worry about it too much, I'm guessing it's barely noticeable.

Yeah barely, I swore last night it was gone. now I see it again this morning lol
 
I installed 3.21.18. No noticable new problem yet. Quickstart+/pixel shift still broken (lololololololol). I haven't played with the "fine tune darkness" thing yet because it's a slider that defaults at 0 and can go +/- up to 30, so I'm not sure what exactly it does or how to watch for it being tuned. I have a feeling you could use it to tune something like a game that is generally 50-70FPS in VRR fairly well, but then it would be wrong for a game that's generally 100-120FPS in VRR. I was hoping it would just be a simple toggle and do something based on the current (or one frame in the past) refresh rate automatically.
 
Hopefully HDTVTest or someone else can make a tutorial on how to use the Fine Tune Dark setting for target frame rates. This is reminding me of Freesync monitors where you needed to adjust Overdrive levels based on whatever frame rate you were getting in game since higher levels would cause too much overshoot at lower frame rates. Not really a big deal unless you are playing a game where the frame rate just fluctuates way too much all the time.
 
Unfortunately the 2021 LG OLEDs also have the hardware issue of VRR gamma fluctuations but include a new setting called Fine Tune Dark Areas to attempt to mitigate the issue but it isn't dynamic so must be adjusted depending on content.

Yeah seems very much like it. It's nice to have all that crap in one menu and toggling BFI seems faster.

I really dislike the LG menu structure because of how deeply nested it is. It makes sense for some options but it could really use some favorites feature where you can put your most changed settings. Or just allow me to make any preset act the same as Game mode. At least on my LG CX and C9 Game mode still offers lower input lag than running any of the other modes with Instant Game Response. So even in desktop use I run my display in Game mode.

New adapter out guys

Click to expand...
I mentioned this in some earlier post and investigated it a bit but it does not seem to be any better than the Club3D, just a bit more convenient since you don't need a separate USB-C cable. On the flipside it means it does not work on newer GPUs that don't have a USB-C output.

I wanted one because the Club3D adapter cannot do 4K 120 Hz from my Macbook Pro but it seems like this might not do that either. Likewise VRR is not possible on this one either.

Afaik it's exactly the same Realtek DP to HDMI 2.1 converter chip on both but CableMatters is USB-C and the Club3D is DP + USB-C only for power and firmware updates. Club3D was supposed to release a USB-C version of their adapter too but I don't know what happened to that.

Yes but it might be a bit more stable, due to being newer. Also might not flicker as much and might not have to switch to 60hz then back to 120hz to fix colour depth.
And it could work with the newer drivers since it's not using the dp 1.4 to hdmi 600mhz clock limit bug.

It's worth a test anyway.

Also where did you see realtek mentioned? I can't find it mentioned anywhere on amazon or cablematters website.

All i see is :
"Synaptics' Cayenne chipset enables companies like Cable Matters to provide reliable, high-bandwidth video solutions that push the performance envelope," says Synaptics Senior Marketing Director for Video Interface Products, Jeff Lukanc. "We are proud to work with Cable Matters to bring the industry's first converter chipset supporting 8K as specified in HDMI 2.1 to market with a leading brand in the consumer electronics industry."

I'm probably wrong in this case. I thought I had seen Realtek mentioned somewhere.

Does it allow for 4K 120 Hz 4:4:4 on the Macbook? Just to be clear, you have the CableMatters adapter? Which Macbook model do you own? Which MacOS version are you using (Catalina, Big Sur etc)?

No, macOS doesn't support the 4K 120 Hz timings on this adapter, though you can see it in the EDID on macOS. Others have reported that it works fine in Boot Camp with the Radeon drivers.
I have the exact adapter you linked.
I have a 2019 MBP 16" running Big Sur.

Thanks! Same experience as when I tried the Club3D adapter with my 2019 MBP.

Basically it just seems that MacOS is again completely shit at display handling and we probably need to wait for something like a "M2" Mac Mini that hopefully comes with HDMI 2.1 if we want 120 Hz on Mac.

I believe the GPU under macOS cannot handle tightened non-standard timings like 1440p 144 Hz and 8-bit RGB 4K 120 Hz over DisplayPort 1.4. 1440p monitors like the PG278Q are limited to 120 Hz.

I filed a bug report and one of the engineers responded that it's not supported by the "hardware". Presumably he meant the driver.

Since it works over Bootcamp it's clearly not a hardware limitation but driver like you said. Now that you mention it, my PG278Q does indeed only go up to 120 Hz with the Cablematters USB-C to DP 1.4 adapter.

I really like MacOS but they really never get around to fixing this kind of bullshit. It's ridiculous that their latest and greatest cannot handle high refresh rate displays.

Do we not have a thread for 2021 OLED?

The C1 popped up on one site. Is a newer retailer, but is supposed to be legit.

Might as well just combined the CX and C1 into a single thread given how they are basically the exact same TV, just with the C1 having a newer processor for some AI thingies. Heck the C1 still suffers from the same VRR problems as the CX too and both have the same band aid fix applied to them.
 
Any news on the 42" C1 or was that just a cock tease? Slutty LG and their daisy dukes & big fat tits!

I think MSRP is going to be $1399.99. They haven't officially released the prices but that is what the leaks showed. I trust that more than some random retailer trying to make more money selling early using last years MSRP.
