Direct Video Info

Direct Video Modes

Passthru is as if the GEM had a 240p/480i output resolution option. It's a 240p/480i output mode that uses the scaler to buffer a few lines of video to stabilize the video timing *

DV1 is zero buffering and sends the native vertical resolution, usually 240p or 480i over HDMI. Horizontal resolution is multiplied to meet HDMI minimum clock frequency requirements.

FX-Direct packages the native resolution in a higher standard resolution (1280x720p) output frame that might be more compatible with switches and other equipment.

* Passthru mode requires 3.9.46.4 or greater
