When you have a setup that includes a projector, you will have the projector and the input that tells the projector what to project onto the screen. There are several different ways that your projector can lag, including the following:

  • Input lag
  • Video lag
  • Component lag

Video lag occurs when you get a sudden drop in frames per second, which shows up as stuttering. It is usually a problem that comes from streaming or from your video source.

How Do You Measure Input Lag on a Projector?
