DisplayPort is a digital standard for transmission between a computer and a monitor, developed by VESA (Video Electronics Standards Association. Link opens in a new window), it is a successor to VGA and DVI.
DisplayPort supports high-resolution monitors and high refresh rates with the ability to transmit digital audio. DisplayPort is often used between graphics cards laptops, and monitors. DisplayPort comes in several different versions (See table).
DSC - Display Stream Compression
DSC - Display Stream Compression is a video compression algorithm considered visually lossless, and it acts as a standard between graphics cards and monitors and cannot be switched off.
DisplayPort cables
The DisplayPort standard has a proprietary connector with 20 or more pins. DisplayPort can be connected to a chain of multiple monitors (Daisy Chain) connected to the same graphics card socket.
DisplayPort standards
The DisplayPort standard has been updated several times since the first standard 1.0 in 2006. The DisplayPort standard is fully backwards compatible, allowing you to choose a cable, better than you have in mind.
DisplayPort with dual 4K displays
To drive two 4K 60Hz displays, you need a DisplayPort cable that supports DP 1.3 (HBR3) or better.
