If you happen to have an RTX 5090 or RX 7900 XTX graphics card to connect to your shiny new OLED monitor, Silkland asserts that its latest 6.6-foot cable is the one for you. It is VESA-certifIed to support the up-to-80 gigabits per second (Gb/s) bandwidth spec of the DisplayPort 2.1 standard, and, thus, to handle the transmission of 8K content that goes at up to 240Hz. https://www.notebookcheck.net/Silkland-releases-6-6-foot-cable-with-VESA-certified-DisplayPort-2-1-80Gb-s-support.952837.0.html
DP 2.1 is only for 8k 60Hz - 10bit or 8k 75Hz - 8bit video.
