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. There are also issues with G-SYNC – apparently, GeForce RTX 3080 users who enable the option on CX and C9 models are getting flickering and/or black screens.

LG hasn’t given an exact date as to when the firmware fix will be available, but it should be released sometime next month. Here’s the complete statement.

“LG has been made aware that some LG OLED TVs are experiencing certain compatibility issues with the recently launched Nvidia RTX 30 Series graphics card. An updated firmware has been in development with plans for a roll out within the next few weeks to LG’s 2020 and 2019 HDMI 2.1 capable TVs, which should address these incompatibility issues. When ready, additional information will be available on the LG website and in the software update section of owners’ LG TVs. We apologise for the inconvenience to our loyal customers and thank them for their support as we continue to push the boundaries of gaming technology and innovation.”
