To its credit, though, LG has quickly tried to tackle the issue and a firmware update should roll out “in the next few weeks.”
“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,” the company said in a statement.
“When ready, additional information will be available on the LG website and in the software update section of owners’ LG TVs. We apologize 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.”
According to Forbes, there are two main problems being reported. First, owners of both the LG OLED 9 and X series have sometimes experienced complete loss of picture, or a black screen, when they tried to apply Nvidia’s G-Sync variable refresh rate technology at 120Hz frame rates.
There seems to be some evidence to suggest that complete loss of picture with G-Sync at 120Hz may not be limited to LG OLED panels with HDMI 2.1, so the problem could be related to the new cards from Nvidia.
The second issue seems to only target the X series models, and “finds the TVs reducing signals output in RGB/120Hz/4:4:4 to 4:2:2 chroma subsampling. This happens irrespective of whether you have G-Sync active or not, or which output resolution you have selected,” Forbes wrote. The end result is noticeable image degradation.
