How is monitor bandwidth calculated?

Jumping up to 4K/30Hz, be on the lookout for a minimum bandwidth on your HDMI cables of 10.2Gbps. Top of the resolution range at 4K/60Hz you will need a HDMI cable with a bandwidth of 18Gbps (minimum) .

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.

In order to stream 1080p or 720p, you will need a bandwidth of at least 5 Mbps . But the best speed for seamless 4K streaming is set at least 25 Mbps.

4.95 Gbps – The minimum bandwidth required to transmit a 1080p signal at 60Hz with 8-bit per channel color depth is 1.65 Gbps per channel, or 4.95 Gbps total.
