Configuring Video Walls with OmniStream decoders is possible with both single-channel and dual-channel decoders, however there are some important differences between them to consider:
- The AT-OMNI-122 is limited to HDCP 1.4 as opposed to the AT-OMNI-121 which supports HDCP 2.2.
- When used in Video Wall configurations, the AT-OMNI-122 is limited to 1080p30 output resolution as opposed to the AT-OMNI-121 which supports up to 1080p60.
- When used in Video Wall configurations greater than 2x2, the AT-OMNI-122 must be configured for Video system mode with Fast Switching disabled.
- When using dual-channel decoders, the Rotation feature can only be used when a single HDMI channel is active.
| 💡 Image rotation is not supported on dual-channel decoders when both HDMI channels are active. Single-channel decoders do not have this restriction. |
- Portrait Mode is only supported on single-channel decoders.
