In this video, we are measuring the input lag difference between a CRT connected over components (IO Board XL 6.1, VGA to Components) and LG OLED C7 connected via HDMI. All of this using a SNAC adapter via the serial connector on the IO board and a modified Nintendo controller with a LED.
I will be doing more test with a LG B9 that I got. It seems that the B9 and CX have half of the input lag according to LG.
