Not for the past few years. Although DP 2.0 has been 'released', there are no products actually shipping with it, and in practice DP 1.4 is the latest standard. DP 1.4 can't transmit 3840×2160 at 4:4:4 144 Hz without Display Stream Compression (DSC). HDMI 2.0 can.

Here's a GPU with DisplayPort 2.1 https://www.mindfactory.de/product_info.php/16GB-Sapphire-Ra...

That monitor was released not three months ago; I was describing the 99.99999% case. DP 2.0 is rare enough that an article[1] was produced this year about its scarcity.

Is there a point for a monitor to use DP 2.0 when the only formats it can display are all supported by 1.4?
