Pixel Format Overview

HDMI displays can use one of two different color formats, YCbCr and RGB.  These color formats are the digital equivalent found in Component Video (YPbPr) and D-Sub VGA (Video Graphics Array) analog signals.

The YCbCr format contains a subset of color coding data, also referred to as Chroma Subsampling and represented in the 4:n:n (Y:Cb:Cr) format.  The left digit denotes luminance, the middle digit represents the blue channel, and the right digit is the red channel. 

The RGB format contains Limited (16-235 bits) and Full (0-255 bits) options which represents the range of the white and black levels that can be displayed.

Depending on the source content and output resolution, each format may offer a slight difference in picture quality.  More advanced information about these formats can be found online. 

AMD Radeon Settings provides support for the following formats for HDMI displays:

  • YCbCr 4:4:4 Pixel Format
  • YCbCr 4:2:2 Pixel Format
  • RGB 4:4:4 Pixel Format Studio (Limited RGB)
  • RGB 4:4:4 Pixel Format PC Standard (Full RGB)
