A Barco imagePRO-4K would take a 120Hz input. But when converting to 60Hz , it will just skip frames, no interpolation done.

...high frame rate in general, 120Hz is recently used in the professional simulation world, since the image generators are capable of rendering 120 fps. It makes a big difference.
240Hz is possible with 3chip DLP, and might also be with direct view LED.
