LG 48CX

A little while back I bought a X-Rite i1 calibration tool for a previous monitor. Can this also be used for the LG CX48? Wasn’t sure after all the initial non calibration tool tweaks if it was still worth it.

Yes you can. Displaycal even has a calibration profile for LG OLEDs you can use. Calman can be used (but it's really expensive) to store a hardware calibration. Personally I'd just use displaycal to adjust RGB and be done with it. I also have an i1display pro but I've been too lazy to do it yet. Screen looks great already with some minor tweaks.
 
Bought a MSI 3080 Trio last night to upgrade my 2080ti, and I did not have a adapter for the 3rd 8 pin.

Now i wait for amazon to deliver it tomorrow, gah the wait!

Great, good to know! I may break it out just to see. And totally agree, screen is perfect with minor adjustments to OLED light, ck trady, brightness etc.
 
Has anyone gotten an RX 6000 series GPU for the LG CX? Curious if VRR and HDMI 2.1 features work well on it.
 
How well would an Alienware M15 laptop w/ a geforce rtx 2070 run this monitor? I know that card doesn't have HDMI 2.1 so I know 120hz refresh rate isn't possible, but I've been gaming at 60hz and don't mind doing so until I build a new system with a more current card. Mainly will be watching movies, gaming, and editing photos.

Thanks.

When using it as a PC monitor, anyone have experience with either a wall mount or desk mount solution? For the wall mounting, I'd prefer an articulating arm that can still fold just about flat as opposed to one of those less adjustable versions that seem to be aimed at TV use.
 
So I played COD BOCW on the RX6800XT with the CX48. Seems fine. What data would you guys want me to use?

Key ones would be that it works at 4K 120 Hz 10-bit color with HDR and that VRR works either using the Freesync option in the TV menu or without it. If you can, try running a game at settings (e.g high raytracing or render res) that put it around the framerate of the lower range of VRR, 40 fps and see if you can see any flicker if it transitions from under 40 to above 40 and back.

You can also use the diagnostics behind hitting the green button on the remote many times until a screen pops up in a corner to see what it sees as output and whether VRR works or not.

Would this stand be a good option for this TV?
https://www.displays2go.com/P-16610...DrT2-xf2RRZ56L8xp8YV78LFQVMV5L5hoCxyIQAvD_BwE

I work/game/watch movies at a height adjustable desk while walking on a treadmill (which I highly recommend for those of you working from home), so having a height adjustable stand is a must, as is having one that will rotate the screen because when photo editing I sometimes have the primary monitor in portrait orientation.

Also bumping my earlier question re: if an Alienware M15 laptop with a NVIDIA GeForce RTX 2070 card will adequately power non-cutting edge games (Stalker Call of Prpyat, Elite Dangerous, Subnautica are a few I'm playing/planning to play) at 4K 60hz - I am happy with a framerate at 30fps or above. (Once the latest cards become available, I will likely build a small form factor gaming PC w/ an HDMI 2.1 card to drive 4K 120hz content).

Thanks!

So how do i know a game has HDR on?

On my living room tv it says HDR when a console game switches into it.

I have my 3080 hooked up now to my LG CX 48, put i don't see HDR pop up as I load a game.

Thanks

I own both too and the CRG9 is now my gf's monitor while I use the CX. The way I use it is to put secondary windows up top - things I don't look at all the time like say email or time tracking apps etc. The apps.I use constantly live in the lower portion of the display which makes it more comfortable.

Your situation is a bit tough because to get enough viewing distance you do want to wall mount. For a sit/stand desk setup you would want a floor stand that is motorized so the display can be raised as you raise your desk. Those are pretty expensive. I just use a floor stand with mine and it is much better than the previous monitor arm setup I had. Less wobble, more distance.

I really liked the CRG9 a lot for work but as a gaming display it was a bit too wide. I liked running many games better at 3840x1440 custom resolution. 3840x1600 is great on the OLED.

Ya I also have mail spotify etc at the top, but I dont want that stuff wearing on the panel so if I am not actively using it I just minimize it. And so I end up not using the top 20-30% of the panel a lot of the time because I will neck pain. So solution is to lower it or get further away from it (or it getting further away from me).

I'm not gonna buy a variable floor stand. That does not make economical sense. But thanks for the suggestion.

I edit photo/videos so I dont find the C49RG90 very good for that. No Adobe Profile and the sRGB is not really good in my opinion. And after seening colors, blacks and generally images on my OLED I cannot go back to that monitor for work. For any non-image work its great tho. I too find it too wide for gaming.

Ideally I would get one of those LG 38" 3840x1600 Ultra wide curved panels. But again. after seeing OLED its hard to go back. The clouding, the inconsistent backlight etc is hard to go back to. I just wish LG makes a 40" 21:9 curved OLED 3840x1600 next year for computer usage. That would be ideal!

But ya. Still no great solution for mounting it on the desk. I think my only bet is the ergotron HX eventhou it wont get my that much more distance. Does anybody know if it can be rotated so that the lower arm is haning out back and the upper arm is over the desk. And would it be able to the the 48" CX weight wise? Because wouldnt that make it so that it is further away from the person. It would requires some room behind the desk, but I am okay with that.

You should see the HDR logo pop up in the top right when you switch to an HDR application. Also you can click the scroll wheel on the remote, point to the input (“PC HDMI 1” on mine) on the bottom left, click it, and a pop up will come up showing your resolution and it’ll say HDR if you’re in HDR.

Most games require you to turn on HDR in the Windows display settings, and then the TV will always be receiving an HDR signal. It's up to your eyes to tell the difference toggling HDR on/off inside games after that.

Can confirm vrr works for me. I forgot to take a picture last night though.
 
This is what I think was the best articulating floor stand I found when looking but it's pricey:

https://www.amazon.com/gp/product/B00681HGB6/


I'd probably get this one below if I was going to switch from it from being on the included stand (on another desk). That is, unless I absolutely required a lot of articulation like tilt and spin. Otherwise you could just roll it on the wheels outside of those requirements.

There is also what looks like a good floor foot stand model at monoprice that someone linked earlier.

My CX55 is currently at 3363 hours, and no burn-in so far.

Of note:

I keep my display at around 0-50 OLED light (except for HDR movies, which I watch at 100).
Lots of static content from work laptop (no screensaver)
For my desktop, I have a 5 minute screensaver (Mystify) with 1 hour off-time.
I vary my content between mostly youtube videos, youtube tv, games, and online forums.
I turn off the display if I'm walking away for a long time.
I run the screen refresher every couple of weeks as long as I can remember.

I have a 2 year Best Buy warranty, so if any permanent burn-in (burn-out) shows up, the panel will be repaired ASAP.

Guys, thank you for your replies.

I ordered it :)
Should have it in around 2 weeks.
Preparing myself mentally for it to arrive, plus installing all games I want to play once on :)
 
Remember if you are running Nvidia 460.89 or 460.79 HDR is broken. When it activates black levels are massively elevated and black becomes grey.

If you use the a proper setting of say RGB / Full in the Nvidia CP and set the TV to Black Level High as it should be... you will see washed out greys for black and this will lead you to think your TV setting is incorrect and set it to Black Level Low instead. This will "look" proper on a black desktop... but you're actually massively crushing the blacks in HDR because it was never the correct setting in the first place.

I'm mentioning this because there is already a HUGE amount of confusion on setting these options to begin with and the broken drivers make it FAR MORE CONFUSING than it should be.

Earlier drivers are working correctly. So before you wonder why your CX settings aren't working the way people say they should, make sure you aren't using either of these drivers. I'm currently using 457.51 and HDR works. (as well as fixing several other issues such as power on flickering and corruption)

I've found that the HDR raised black seems to happen randomly, and disabling/enabling Gsync fixes it....till it happens again. It's listed as an issue in the release notes of the drivers that came out today at least, so even if Nvidia hasn't fixed it yet they're at least acknowledging it.

As to black level high/low....the TV knows what to do and does it right with the black level set to auto, people should just leave it there.

Anyone using a 1080Ti?

Do you play at 4k? or 1440p? How is performance?

Looking to build a new PC within the next 6 months once I can snag a 3090 or maybe a 3080Ti (if annoucned) but for now I'm stuck with a 1080Ti.

I am. At 4K. Performance is brutal out of the box. Think I started out with something like 10 FPS. Turned off Film Grain and Chromatic Aberration immediately and got to around 20 FPS. I'm reading some tweak guides on other settings that affect performance and can get to just shy of 30 FPS by lowering a bunch of them from Ultra or High to Medium. I'll continue to read up and maybe find some guides or videos from other people using a 1080Ti but I might have to shelf this game for now. I'm not going to play it at 26 FPS along with severely compromised visuals. I want to experience the game as it was intended and trying to run a visually stunning game like this at 4K on a two-gen old card isn't going to be that, I'm fairly sure of it.

Performance on a 3090....WITH ALL RAY TRACING OFF....is bad at 4K without DLSS, which a 1080Ti doesn't have the option of doing. So....trying to do something that is bad on a 3090 with a 1080Ti....big nope.

Lol oh trust me, it’s not by choice. I would LOVE to be playing this on a 3080. I just haven’t been able to snag one, and I’m not paying scalper prices out of principle. I’ll just have to keep waiting.

Oops, I thought that with all of the Cyberpunk talk, you were asking specifically about that game. 4K performance in other games can be quite good. Doom Eternal runs amazingly well, for example, but that engine is primo. I mainly play older games due to my backlog so I can’t speak to many other new games. RDR2 is definitely playable at 4K, but expect to lower some settings.

That's fixed, the new EDID is based directly from my own CX EDID export, the only change is to increase the FRR (lane) speed from 10Gbps to 12Gbps (to get a full 48Gbps sync) everything else is untouched. G-SYNC/VRR works fine.

Cyberpunk HDR is broken no matter what driver you use and has much worse black level issues than the new drivers. Doesn’t change the fact that 460.xx drivers are broken in HDR even on the desktop.

Yeah, black level is wrong. It’s more subtle than the disaster that currently is Cyberpunk HDR mode but it’s there. Set a black desktop background, enable Windows HDR mode, and you’ll notice that you can see the transition between grey screen and black bezel when normally both would be black and difficult to discern as they are in 457.xx

Might not even affect Cyberpunk considering the darkest shade it ever puts out in game is “IPS grey”

Damn, shame on me! There are indeed raised blacks on the desktop at least. Just did a back and forth test again. Haven't seen it because it use brightness to 48 as a standard for PC HDR gaming (and 46 for Cyberpunk). Does not seem to affect the game, at least for my eyes.
