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.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.
Such short lengths aren't down to VESA being picky, as the DisplayPort specification doesn't actually state length requirements, other than all DP cables under 2 metres in length must be able to support HBR2 signalling as a minimum. However, VESA'sIn other words, vendors don't seem to be willing or capable of making long DP80 cables and then getting them certified at the moment. The industry is arguably benefitting from the fact that any cable can be sold as being 'DP 2.
Not that there's much DisplayPort 2.1 capable hardware on the market, anyway. AMD's Radeon RX 7000-series and Intel's Alchemist Arc cards are, but only to UHBR13 and UHBR10 respectively. Nvidia's current RTX 40-series still uses DP1.4a which has been around since dinosaurs were playing Pong.is a 4K 240 Hz OLED gaming monitor that has a DP2.1 socket with UHBR20 signalling but you won't be able to use that mode, as no graphics card currently offers that transmission rate.
