The KONA Downstream Keyer does not support UltraHD/4K formats, but is

Control Panel 8K Operation (KONA 5 only)
This section describes the AJA Control Panel operations specific to KONA 5 in 8K
Mode. This mode supports the capture or playback of 8K material, using four or
two input or output 12G-SDI signals. Note that in 8K Mode, you can still capture
and playback single link SD, HD, and 2K formats.
When KONA 5 is operating in 8K mode, the following Control Panel screens and
capabilities are not available:
• Audio Mixer Screen
• DS Keyer Screen
• LUT Screen
• Color space conversion.- You must manually match the output color space
to incoming signal's colorspace. For example, if using 444 signals the RGB
colorspace is required.
NOTE: AJA recommends always using KONA 5 in 4K mode, unless you specifically need
8K functionality.
