(Edit: the tearing is not visible through the device, so quite a bit less damning than I thought.)

The tear and color lag on this picture of a moving chart is damning: https://i0.wp.com/kguttag.com/wp-content/uploads/2023/01/MQP...

As is this quote:

  > I also ran a small experiment where I sent a camera flash off in a dimly lit room and measured the delay with light sensors using one sensor to trigger an oscilloscope’s capture and the second light sensor to capture the display response. It typically took a little over four 90Hz frame times (~40 to 50ms) for the flash to show up on the image.
