The ROLINE DisplayPort Cable (product ID 11.04.5812) supports DisplayPort version 1.4, which includes the capability for Display Stream Compression (DSC). This version of DisplayPort can handle high bandwidth requirements, including the transmission of signals at resolutions and refresh rates that would require up to 32.4 Gbps per lane. Since your monitor requires 49.8 Gbps, which is within the capabilities of DisplayPort 1.4 when using multiple lanes and DSC, this cable should be compatible with your needs.
