DisplayPort Multi Stream Transport has the ability to allow multiple external
monitors to be connected to host devices such as laptop via a USB type-C connector
and display different graphical content. There is, however, a limitation in how
many pixels can be sent down the display pipe.
adding a second external monitor via a type-C MST hub, both monitors must drop
the resolution down to share the bandwidth.
said, it all depends on the PC’s native GPU performance and the DP version it
① DisplayPort 1.2
should allow connection of two 1080P monitors.
② DisplayPort 1.4
should allow connection of two 2K monitors.
③ DisplayPort 1.4,
which supports DSC 1.2, should allow you to connect two 4K monitors, one
running at 60 Hz and the other at 30 Hz.
Stream Compression (DSC) 1.2 supports visually lossless compression of
ultra-high definition (UHD) displays while also supporting high dynamic range
general, if the external monitor is not up to the required resolution, such as
4K@60Hz, it depends on how much bandwidth the computer's DisplayPort version
supports as well as the performance of the native GPU output.
