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

The below chart assumes the device is running direct to the upscaler, and the recommendations may change based on switches or splitters inserted in between.

Check the hdmi switch reference guide for compatibility.
