Hi5-4K-Plus Mini-Converter v1.12 16 www.aja.com
HDMI/DVI
Choose Auto, HDMI, or DVI. When DVI is selected, any audio signals present are
not passed. Choosing “Auto” automatically selects the output mode based on the
attached device’s capabilities.
HDMI 1.4/2.0
Choose Auto, HDMI 1.4, or HDMI 2.0.
Your selection for this control will depend on whether you are connected to a
sink device that supports HDMI 2.0 (maximum bandwidth of 18 Gbps) or HDMI 1.4
(maximum bandwidth of 10.2 Gbps).
Hi5-4K-Plus supports HDMI 2.0 and can pass through 4K/UltraHD high frame rate
(HFR) signals such as 50, 59.94 or 60.
• Auto (default setting). If connected to an HDMI 2.0 sink device, the 4K UHD
HFR source will pass straight through with no loss of data. If connected to an
HDMI 1.4 sink device, the unit will reduce its output data rate by dropping
every other video frame, reducing bit depth, or both.
• HDMI 1.4. When the video source is 4K or UltraHD with a high frame rate (HFR)
including 50, 59.94 or 60, the Hi5-4K-Plus will automatically drop every other
video frame, reduce bit depth, or both. This setting can be used to support
connection to an HDMI 1.4 sink device such as a monitor.
• HDMI 2.0. When the video source is 4K or UltraHD with a high frame rate (HFR)
including 50, 59.94 or 60, the HDMI 2.0 setting supports the unit in passing
through 4K/UltraHD high frame rate (HFR) signals such as 50, 59.94 or 60.
HDR Metadata Screen
Click on the HDR Metadata tab to view and, if necessary, make changes to the
Hi5-4K-Plus High Dynamic Range metadata. For SDI this metadata defines the
signal's Transfer Characteristic and Colorimetry. For HDMI it defines the signal's
EOTF and Colorimetry and sets parameters for the Dynamic Range and Mastering
infoframe. The HDR metadata also provides a mechanism to inform an HDMI sink
device (such as a TV or monitor) that the video content is HDR encoded.
