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
Direct Video Modes Lag or Latency
DV1 = zero lag
Passthru = line doubler
FX-Direct = typical scaler line latency

Check the hdmi switch reference guide for compatibility.
