AT-OME-MS42
25
Device Operation
• The HDMI
OUTPUT
port supports up to 4K @ 60 Hz, 12-bit, with HDR.
• 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
•
HDR / Dolby Vision / HLG formats cannot be down-scaled to 1080p.
•
The internal scaler will be bypassed if the connected display supports the resolution and timing information from
the source device.
•
The HDBaseT
OUTPUT
port supports up to 4K @ 60 Hz. However, HDR is only supported at lower resolutions.
•
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.
