Assuming that they don’t own one already, GeForce RTX 3080 owners may want to put LG’s OLED TVs back onto their holiday wish lists. The Korean display giant has released a statement confirming that a firmware fix is on the way for its 2020 and 2019 HDMI 2.1 models, which haven’t been playing nicely with NVIDIA’s newest flagship GPU.



Echoing our original report from Sunday (which we’ve updated), users have been complaining about LG’s CX Class OLED displays downsampling chroma signals from 4:4:4 to 4:2:2 in 4K/120 Hz. The biggest problem with this is blurry text, which is a definite no-no for PC usage.

Will it need another update when Big Navi ships?

I really want this to be my next monitor, but it will have to wait until after Ryzen 3 and my next video card. Could be a while.

I doubt it. I think it was a simple oversight, or maybe intentional, that the televisions were shipped without HDMI 2.1 features enabled since other televisions with HDMI 2.1 that people tested worked fine.
 
LG pushed out a firmware update that addresses this issue for the Korean region. Should be pushed to other regions soon.
 
I can't bring myself to use my LG 55CX to be my full time monitor yet. May decide to if I can get a 3000 series card.
 
Was lucky enough to score a Strix 3090 this week on Amazon. Some good news for LG owners wondering about it. If your t.v. has self updated to the latest firmware 5.00.03 it's pretty much a Plug'n'Play experience. Just make sure you've got a good HDMI 2.1 cable or you can have screen blank outs(atm all I have are some 2.0s supposedly rated at 48 GHz). Was rocking 4K/120 Hz/HDR/12-bit/G-sync all day yesterday.

Yeah, I'll be limping along probably until around February when it's paid off but I'm glad to have it and now I won't have to upgrade this rig for years now. Everything's pretty much matched up. The only thing left on my wish list is a 2TB PCIe 4.0 NVMe but I can wait another year or so.
