Graphics cards and port drivers do not usually indicate the version of DisplayPort they support but they will show maximum resolution and refresh rate (e.g. However, for the best image quality, it is best to avoid compression of any kind. Compared to video transmission without compression, DSC saves power and can allows for resolutions up to 16K (15360 x 8460). This 'light compression' allows video to be encoded and decoded in real time with very low latency, making it ideal for high performance applications like gaming. Display Stream Compression (DSC) is a new standard first introduced in DisplayPort 1.4 that enables visually lossless compression of 2:1 or 3:1. The only way to transmit more bits is to add more lanes to the cable or compress the signal.

High resolutions of 8K and beyond, greater color depths and increasing frame rates push the limits of video cables, even high bandwidth cables like DisplayPort. What is Display Stream Compression (DSC)? Depending on the resolution, active cables can easily reach 150-ft or more. They regenerate or increase the strength of the signal so it can be transmitted further. If you need greater distance, you have two choices: a signal booster or an active cable. Depending on the quality of the cable and other factors, you may be able to transmit video and audio over greater distances. The maximum length of a passive DisplayPort cable is at least 15 meters/33 feet.

The longer the cable or the more data (higher resolution) you try to push through it, the more likely the signal will weaken and suffer from errors and interference. To make it easier to find the cable you need, the VESA DisplayPort Task Group gives transmission speed a name.įor more detail, see DisplayPort Cables and DisplayPort 2.0 Monitor Configurations below. Updates to the DisplayPort standard typically include a boost in transmission speed (also referred to as bandwidth). Resolution, color depth, number of monitors, refresh rate are all dependent on how much data the cable can transmit. The primary difference between them is transmission speed.
