Hi, I recently bought this TV after seeing it was recommended for gaming since it has low input lag. I noticed some lag when using the TV as a PC display. After testing it’s consistently about 2 frames @60hz which is more than the 15ms in the review. I am using game mode on HDMI port 5 and also using the recommended color settings on the site. I am also using a sound bar with bluetooth subwoofer (Vizio SB3621n-E8) but it doesn’t seem to be causing the issue as I tested without it as well. Is there something I am missing, or maybe my test is flawed?

I made a simple program that counts up 1 number every frame and runs at 60fps. I made sure to take the picture in portrait mode to account for the rolling shutter. https://i.imgur.com/x15VJC4.png
