LG reveals the world’s first G-Sync Compatible OLED TVs

LG has partnered with Nvidia to create the world’s first G-Sync Compatible TVs; updating their 2019 lineup of OLED screens to support Variable Refresh Rates over HDMI 2.1. 

Let’s be clear here; these screens are merely G-Sync Compatible. There’s no G-Sync modules or anything fancy here. These screens support HDMI 2.1’s VRR (Variable Refresh Rate) standard and pass Nvidia’s G-Sync Compatible test suite. Any graphics card that supports HDMI 2.1 VRR can enjoy variable refresh rates on these screens.  

LG’s 2019 OLED TVs (model 65/55E9, model 77/65/55C9) will support Variable Refresh Rates of up to 120Hz at 1440p and 1080p while also boasting support for 4K 60Hz. No Nvidia graphics card offers full support for HDMI 2.1, so 4K 120Hz is not an option. LG specifications for their TVs also make it unclear if 4K 120Hz is even possible on their OLED screens. 

Other HDMI 2.1 features like auto low latency mode (ALLM) and enhanced audio return channel (eARC) are also available on LG’s latest OLED screens. G-Sync Compatability will arrive through a future firmware update. 

LG’s G-Sync Compatability feature is basically an Nvidia stamp of approval over the screen’s HDMI 2.1 VRR implementation. While some will say that Nvidia is stamping its G-Sync brand over something that isn’t really G-Sync; it remains a useful way for Nvidia users to know if both their screen and graphics card support VRR. 

Nvidia has also confirmed that HDMI VRR support will be supported on Nvidia RTX 20 series graphics cards on a future driver release. This will enable HDMI 2.1 VRR support over a broader range of TV screens and monitor.
