LG adds G-Sync support for variable refresh rate to its 2019 C9 and E9 OLED TVs. Although the models do not include G-Sync hardware, LG has partnered with Nvidia to get each set certified through Nvidia & G-Sync compatible testing. When connected to a PC with an Nvidia GPU, the TV must be able to display smooth variable refresh rates up to 120Hz.
LG & # 39; s TV & # 39; s from 2019 already supported variable refresh rates via HDMI 2.1 and could be used with the Xbox One X. PC GPUs do not yet support HDMI 2.1, so this was previously not an option on this TV & # 39; s. Nvidia recently opened its own G-Sync standard, but opened up compatibility with a much wider range of panels that previously only supported AMD hardware.
However, it is unclear what exactly you need on the PC. "We are excited to offer G-Sync compatible support for LG & # 39; s 2019 OLED TVs and HDMI Variable Refresh Rate support for our GeForce RTX 20 Series GPU & # 39; s," says GeForce marketing manager Matt Wuebbling in the Announcement. This suggests that VRR via HDMI (unlike DisplayPort, which normally requires G-Sync) may be limited to Nvidia & # 39; s most recent RTX generation GPU & # 39; s.
Even if that's the case, the announcement is remarkable because it makes LG OLED TVs the most practical and attractive option for anyone who wants to build a large-screen gaming device. There are more expensive alternatives, such as Dell's FreeSync-supporting Alienware 55 OLED Gaming Monitor and Nvidia's proprietary BFGD screens, but it's hard to see who would go for it at this point. AMD GPU owners can simply buy an RTX 2080Ti with the money they would save and get a better TV to boot.
LG says the G-Sync compatibility will come via a firmware upgrade "in the coming weeks."
