What 4K video profiles can XTx43/XDx33/4Kx42 players output over HDMI?

Last Updated: July 16, 2015

The following table illustrates what 4K color spaces and bit depths are supported over HDMI output. Note that these video profiles are separate from the color-space and bit-depth values you specify when encoding the video. The video quality is determined by the lesser of these two video profiles.

 Resolution

 8 Bit

 10 Bit

 12 Bit

 4Kp24
 4Kp25
 4Kp30

 4:4:4 (RGB)*

 4:4:4 (RGB)

 4:4:4 (RGB)

 4Kp50
 4Kp60

 4:4:4 (RGB)
 4:2:0

 4:2:0

 4:2:2
 4:2:0

*This is the only 4K video profile supported over HDMI 1.4; all other profiles require a display with HDMI 2.0 support.


You can set 4K video output to 10-bit 4:2:0 when creating a new BrightAuthor presentation (in the New Project window). The bit depth and color space is also fully customizable using the roVideoMode.SetMode() method in BrightScript
