Bare bestill i hht specs på display port protokollen:


DisplayPort version 1.4 was published March 1, 2016.[21] No new transmission modes are defined, so HBR3 (32.4 Gbit/s) as introduced in version 1.3 still remains as the highest available mode. DisplayPort 1.4 adds support for Display Stream Compression 1.2 (DSC), Forward Error Correction, HDR10 extension defined in CTA-861.3, including static and dynamic metadata, the Rec. 2020 color space, and extends the maximum number of inline audio channels to 32.[22]
DSC is a "visually lossless" encoding technique with up to a 3:1 compression ratio.[21] Using DSC with HBR3 transmission rates, DisplayPort 1.4 can support 8K UHD (7680 × 4320) at 60 Hz with 30 bit/px RGB color and HDR, or 4K UHD (3840 × 2160) at 120 Hz with 30 bit/px RGB color and HDR. 4K at 60 Hz with 30 bit/px RGB color and HDR can be achieved without the need for DSC. On displays which do not support DSC, the maximum limits are unchanged from DisplayPort 1.3 (4K 120 Hz, 5K 60 Hz, 8K 30 Hz).[23]

Dessuten så kommer kabel an på flere faktorer som f.eks oppløsning, farger, ergo jo mer data du skal dytte gjennom kabelen desto større båndbredde behøver den, derfor fikk du v1.4 som eksempel.


Her kommer utdrag fra v1.3
This bandwidth is enough for a 4K UHD display (3840 × 2160) at 120 Hz with 24 bit/px RGB colo
