4K/144Hz Data Rate
Posted: 08 May 2018, 14:02
These new monitors (4K/144Hz) use two DP cables or compression (DSC) with single cable?
The DisplayPort 1.3 and 1.4 provide the extra bandwidth required for 240Hz at 1440p, 120Hz at 4K, 60Hz at 5K, and 30Hz at 8K. The main difference between the DP 1.3 and DP 1.4, is that the latter supports DSC (Display Stream Compression) which allows it to deliver 144Hz at 4K, 120Hz at 5K, and 60Hz at 8K – but with compression.
It is weird that that they didn't use HDMI 2.1 for these monitors though.HDMI 2.0 can be used for 240Hz at 1080p, 144Hz at 1440p, and 60Hz at 4K. The latest HDMI 2.1 adds native support for up to 144Hz at 4K and 30Hz at 8K.
