Notes on Scaling

The following section provides important information about how the AT-OME-ST31A processes 4K (UHD) video signals.

1. The HDMI OUTPUT port supports up to 4K @ 60 Hz, 12-bit, with HDR.
2. If the source is 4K, and the HDMI OUTPUT port is connected to a 1080p (not 4K-capable) display, then the output will be down-scaled as follows:

Input Output

4K @ 24 Hz 1080p @ 24 Hz

4K @ 30 Hz 1080p @ 30 Hz

4K @ 60 Hz, 4:2:0 1080p @ 60 Hz, YUV/RGB 4:4:4

1. HDR / Dolby Vision / HLG formats cannot be down-scaled to 1080p.
2. The internal scaler will be bypassed if the connected display supports the resolution and timing information from the source device.
3. The HDBaseT OUTPUT port supports up to 4K @ 60 Hz. However, HDR is only supported at lower resolutions.
4. The HDBaseT OUTPUT port will down-sample to 4:2:0, if the source is 4K @ 60 Hz, 4:4:4, 8-bit. However, the HDMI OUTPUT will remain at 4K @ 60 Hz, 4:4:4, 8-bit, if the output is connected to a 4K-capable display.
