Below you find that each combination of resolution timing, bit depth, and color space has a specific bandwidth requirement, which can be expressed as an uncompressed bandwidth, a compressed bandwidth, or both. With the newer HDMI specifications, some HDMI sources with the ability to send FRL signals may choose to transmit a signal as compressed or uncompressed, depending on whether the display’s EDID supports Display Stream Compression (DSC). When a source uses DSC, it allows most resolutions up to 4K to be transmitted with a bandwidth under 24 Gbps, and resolutions up to 8K under 48 Gbps.
