Question about LG OLED77CX

Hello

According to a test, the TV is supposed to be one of the best in terms of input lag:

"Even without HDMI 2.1, LG 2020 OLED TVs are excellent performers in the region. We measured the input lag in gaming mode to be 13ms - 1080p SDR, 4K SDR and 4K HDR. Currently, we cannot measure input lag in VRR and 4K120, where the company says it is only 6 ms. 13 ms is the lowest input lag we have measured on a 4K TV to date, but is in line with the performance of 2019 models."
