According to AVS, Gsync and Chroma are fixed at all resolutions/bit depths available so the CX is golden now.

The real issue remains getting a hold of a 3080/3090.

If that's the case then they really delivered. I knew they said they would fast-track the update but I really didn't expect it to come so quickly, and sort of expected one issue to be fixed now and the other in a future update.

Yeah...not having a 3080 to fully unleash the beast is really hurting right now! I kind of want to wait on the 20 GB cards, but not sure if I'll be able to hold out.

Golden news! My PNY XLR8 3090 comes in Thursday 10/8! Can't wait to use this display to her full potential.
 
I'm not a hater I'm just a waiter. Early bird gets the worm but the second mouse gets the cheese. :D

Very good news. Everything should come together nicely in time with a 3090 + LG 48 CX for me now that the smoke is clearing. If I can, I'll get a 3090 (with dual hdmi) ahead of time and see what the LG OLED prices are in november. I should be in business over the holidays at the latest I hope depending on 3090 releases and stock (at retail prices).
 
Now if only they can get a fix out for raised blacks with Dolby Vision. Most of the HDR content I watch is in Dolby Vision so the raised blacks in that has been quite a bummer. Not as bad as having IPS blacks (which is grey actually LUL) but still not the true OLED blacks we all want.
 
I turned QuickStart+ back on also and will see over the next few days if the screen shift bug is fixed as well.

The raised blacks appear in any HDR preset or only in Dolby Vision?

I haven't tried much standard HDR10 content yet since 2080 Ti does not allow for HDR at 4k120Hz 4:2:0, wouldn't be surprised if it did happen though. Anyways:

 
I have an RTX 3080 with latest drivers.

-Full RGB 10bit @ 120hz is fantabulous
-Instant game response no longer causes insane screen blinking when activated

- Gsync feels real good!

My body is now ready for Cyberpunk 2077

Those of you getting RTX 30XX cards, be aware, there is an issue with 3rd party builders using inferior filter caps near the GPU on some of the cards. There is supposed to be at least one array of the smaller caps among the six on the back of the GPU, according to nVidia specs. It is speculated that it is causing CTDs on cards with high boost clocks and power limits. The larger/ cheaper caps cannot filter properly at higher current levels, either producing noise and/or they are not capable of charging/ discharging fast enough.

There is a new NVIDIA driver released today that "fixes" this issue. It's keeping core clocks down under 2.1ghz more around the 2.0 ghz max range. I have a Gigabyte Eagle 3080 and no issues or stability problems even when games hit 2040mhz core. Now, to test the new CX firmware!

It isn't inferior caps. The issue is far more complicated than that.
 
Latest test results with 3080 and CX 48 with updated firmware:

  • Full 4:4:4 chroma and 120hz 4K works like a champ - Gorgeous
  • GSYNC also working great tested at 60, 100, 120hz - Gorgeous
  • Still restricted on custom resolutions over 60hz in NVIDIA Control Panel. I can create 3840 x 1600 @ 60hz but anything over 60hz, I just get a blank screen on the CX. I've tried everything I can think of but no dice
  • My Club 3D adapter arrives tomorrow. I will be testing 2080 Ti and 3080 custom resolutions and over 60hz with the adapter
 
I can confirm the CAC-1085 adapter and 2080 Ti now renders 4K 120 Hz at 4:4:4 with the new CX firmware.

Awesome! Looking forward to getting a firmware that works on my TV. The Korean one did not work in my EU CX48, just does not pop up the update dialog.

If Club3D can get VRR working on the adapter, that would make buying a 3080 pretty pointless to me and might as well wait for price drops or "3080 Ti/Super" or whatever.

For me these exact settings work perfectly fine for adding 3840x1600 @ 120 Hz using the Club3D adapter. I would wait for firmware or driver fixes. Setting the desktop to that resolution tends to drop it out of HDR though but you can get 3840x1600 and HDR working together in games just fine.
Click to expand...

Wait. What? kasakka didn't you say in this thread that 3840x1600 @ 120hz works with the club3d adapter? This doesn't make sense. Why wouldn't 120hz work at this rez on an actual 3080 but work on the adapter with a 2080 ti?
 
I've tried to update the PAL version. No success. The new version is 03.11.25 - which isn't available on the UK website yet. An older one is thought (03.11.05), one that isn't pushed yet through OTA (latest OTA for me was 03.10.4). I used that to test if the procedure is correct and it worked through an USB drive on the side of the television.

I've also tried to just rename the Korean Firmware to the filename of the older UK version that did work - but it doesn't trigger the 'Do you want to update' dialog on the screen unfortunately. So we have to wait for a PAL compile.

I have send LG Customer Service an email asking availability as well as why newer firmware is available on the website but not OTA.

I have absolutely no idea. All I did was just open the custom resolution box in NVCP running latest drivers, type in 3840x1600 120 Hz in its boxes and add it. No timing changes or anything. NVCP is also set to use display scaling, setting it to use GPU scaling might help as it would then create 3840x1600 on the GPU and output it scaled to 3840x2160 with black bars. Same end result pretty much.

I've got a response on this from LG. They're working on the firmware for PAL.

Right I've tried all settings I can think of trying to create any custom resolution above 60hz and it just blanks out. I've tried different scaling settings in the NVIDIA control panel including having the GPU scale and the display. It definitely isn't a bandwidth issue as it should have clearly been able to handle that before the firmware update. Personal opinion is that it is a strange HDMI 2.1 to HDMI 2.1 issue between the video card and the display. If custom resolutions work with the Club 3D adapter, it's got to be DP 1.4 related.

Either way, awesome display but I am know I am in the minority where the custom resolution is a deal breaker for me if I can't get it working correctly... Shouldn't be this hard. The only other thing I can think of is when you create a custom resolution in NVCP, I think it is trying to set it in the TV mode where all the 60+hz refresh rates are under the PC list of resolutions. Not sure if there is any other way to do this.

EDIT: Ok, been trying a ton of different custom resolutions and refresh rate. I've found that regardless of ANY resolution I try, it's the custom refresh rates that make it not function correctly. Definitely not a bandwidth issue or even a resolution/aspect ratio. Here are the list of settings I have tried, all result in a black screen

  • 2560 x 1440 @ 75hz
  • 2560 x 1440 @100hz
  • 3840 x 1600 @ 75hz
  • 3840 x 1600 @ 100hz
  • 3840 x 1600 @ 120hz
  • 3840 x 2160 @ 75hz
Yet if I choose any of the precreated resolutions/settings, they are work with the scaling settings in the NVIDIA control panel such as 2560x1440 @ 100 and 120hz, 2560x1600 @ 60hz etc etc.

As a final solution I would try reinstalling drivers with the clean install option in case there is something weird going on.

The other option to define custom resolutions is Custom Resolution Utility but it's also an easy way to end up with no image. If you have a FE card then having only one HDMI port is going to be a problem here as with two you can just toggle to the other one and run in extended mode to fix issues if one screen ends up blank. If you have another monitor you can connect then you could try CRU. I don't know which section you would use to define the custom resolutions, probably need to add a DisplayID block. In my experience CRU vs NVCP is no difference in behavior though.

Just tried this with the latest drivers, clean install and I even switched to the other HDMI port on my 3080 for kicks. No difference. ANY custom resolution, even 3840x2160 at a rate higher than 60hz, results in a black screen.

Did you try to reset the TV? I can't get custom resolutions working either (3840 x 1600 @ 120hz), but 120hz 4K works fine.
 
I can confirm the new firmware fixes the G-sync/Chroma issue on the CX models. So happy it was resolved right away :) Now back to gaming.

Excellent news indeed. Now I'm really excited to get a 3090. Come on Amazon, hurry up and ship that sucker!
 
Some people are reporting stutter/frame skipping above 96hz with Gsync. Anyone experiencing this?

Been playing a good solid hour of No Mans Sky, and I do not notice any stutter above 96hz? If anything since the firmware update it has been much smoother (at least for me).

G-SYNC was never limtied to SDR.

Windows does not support HDR at 8-bit 4:2:0. The minimum for HDR is 8-bit RGB / 4:4:4 with dithering or 10-bit 4:2:0.
