HDMI 2.2
Calculate HDMI bandwidth by multiplying the number of vertical pixels (plus Vblank), horizontal pixels (plus Hblank), bit depth per channel, and frame rate. HDMI bandwidth is more complicated when accounting for chroma subsampling and video compression. This calculator uses Video Identification Codes (VIC) for TV signals, which include predefined signal data. For PC signals, it uses VESA Coordinated Video Timings (CVT), which rely on different equations to account for variable blanking and may yield estimated results.
Remember that a calculator makes bandwidth calculation easy, but as the HDMI specification changes, this calculator is continuously being developed and may not display accurate results.​

Nerd Notes*
4:2:0 chroma sampling requires a minimum signal of UHD, 4K, or 5K @ 50 Hz.
4:2:2 chroma sampling below 12-bit depths are encoded at 12-bit for chroma sampling alignment reasons.
4:4:4 chroma sampling is equal to RGB encoding.
DSC or Display Stream Compression, can be used in HDMI 2.1 and beyond to reduce bandwidth by up to 3.75:1.

All CVT calculations provided use RB Version 1, which maintains a constant HBlank. Versions 2 and 3 include variable HBlank lengths.
4:2:0 chroma sampling requires a minimum clock rate of 590MHz; around UHD, 4K, or 5K @ 50 Hz.
4:2:2 chroma sampling below 12-bit depths are encoded at 12-bit for chroma sampling alignment reasons.
4:4:4 chroma sampling is equal to RGB encoding.
