Orah 4i delivers video signal over the stitching unit HDMI 2.0 with supports HDMI 4096x2160 resolution at 30 fps and above.

The actual Orah 4i output resolution depends on capabilities of the sink HDMI device you plug to it. Please refer to your third party equipment to check on supported resolutions and framerates.

For optimal resolution on the HDMI port, we recommend configuring Orah's video mode to 4K DCI (4096x2048).






Nothing is showing up on the HDMI device

Please follow these steps :

  • Try to reboot Orah 4i with the HDMI cable plugged in and your device power on.
  • Try to unplug and plug again the HDMI cable on your device rather than on Orah 4i itself.
  • Try changing Orah 4i video mode to match the resolution your device is capable of.

If none of the above solves the problem, please read the instructions below.

Using Orah 4i HDMI output with Blackmagic Design Decklink and ATEM equipment

When plugging Orah 4i to a Blackmagic design ATEM switch, you need to plug the HDMI cable on the switch after it has been connected to Orah 4i HDMI output. You may need to reboot unplug and replug the HDMI cable on the ATEM switch for the video to display.

Please note that most Blackmagic design equipment will not display any video signal unless they are configured at the correct resolution and framerate.
