The messy DisplayPort 2.1 specs mean you could be limited to a monitor cable too short to be of any use if you want to hit 4K at 240 Hz

DisplayPort is generally seen as the superior technology for transmitting images from a graphics card to a monitor, but the latest 2.1 version is causing all kinds of headaches. Poor quality or very short cables limit how useful the tech actually is, but the confusing specs don't help either.

The DisplayPort 2.1 specification was released in October 2022 and mostly consisted of the cable certifications required to fully support the UHBR10, UHBR13, and UHBR20 signalling modes—10, 13, and 20 Gbps respectively. The last one is the most significant as a four-link DisplayPort 2.1 setup, using UHBR20 signalling, can transmit a 4K frame at 240 Hz, without needing to use DSC (Display Stream Compression).
