LG is adding G-Sync variable refresh rate support to its 2019 C9 and E9 OLED TVs. Though the models don’t contain G-Sync hardware, LG has worked with Nvidia to get each set certified through Nvidia’s G-Sync Compatible testing. When hooked up to a PC with an Nvidia GPU, the TVs should be able to display smooth variable refresh rates of up to 120Hz.
LG’s 2019 TVs already supported variable refresh rates over HDMI 2.1 and could be used with the Xbox One X. PC GPUs don’t yet support HDMI 2.1, so this wasn’t previously an option on these TVs. Nvidia recently opened up its proprietary G-Sync standard, however, opening the door to compatibility with a much wider range of panels that previously only supported AMD hardware.tech, The Verge, The Verge - All Posts
