DisplayPort 2.1 Explained
How-To Geek, Friday, December 27th, 2024
DisplayPort 2.1 is crucial for supporting higher resolutions and refresh rates on PC monitors, such as 4K@360Hz HDR monitors.
High resolutions such as 4K coupled with increasingly higher refresh rates and HDR, which requires 10-bit color, demand higher and higher bandwidth. While the currently dominant video interface in PC space, DisplayPort 1.4, is enough right now, it won't be in the future. Enter DisplayPort 2.1.
Why DisplayPort 2.1 Matters
At the moment, the maximum refresh rate found on even the best 4K monitors is 240Hz. Add 10-bit color needed for HDR, and the total bandwidth for an uncompressed 4K@240Hz video signal with 10-bit color is almost 80Gbps!
