What is DP video port?
DP (DisplayPort) is a digital display interface standard developed by the Video Electronics Standards Association (VESA) to connect computers and display devices such as monitors and projectors.
Features of DP video port:
. High bandwidth: supports data transmission rates up to 32.4 Gbps (DP 2.0 version) or higher (such as DP 2.1, but pay attention to market popularity).
. Multi-screen output: supports multi-stream transmission (MST), and multiple monitors can be connected through one port.
. Audio support: capable of transmitting high-quality audio signals.
. High resolution: supports up to 8K resolution (7680x4320) and higher resolution (depending on the specific version and standard).
. Lockable connection: The interface design can provide a physical lock to prevent accidental detachment.
What is DP++ video port?
DP++ (also known as DisplayPort++) is an extension or enhanced version of the DP interface, which means that the interface not only supports standard DP signal transmission, but also has the ability to convert and be compatible with other video output protocols.
Features of DP++ video port:
. Multi-mode support: In addition to supporting standard DP signals, the DP++ interface can also convert DP signals to DVI or HDMI signals through internal conversion circuits or with corresponding adapters.
. Compatibility enhancement: This design greatly increases the flexibility and compatibility of the interface, so that users are no longer restricted by the interface type when choosing display devices.
. Conversion method: If the video source supports dual-mode DisplayPort (DP++), a passive adapter can be used to send DP video to a single-link DVI or HDMI monitor. In this case, the DP++ video source performs the conversion, not the adapter.
Standard DisplayPort (DP) can only support DP signals and will require an active adapter to convert to HDMI or DVI signals. Dual-Mode DisplayPort (DP++) offers flexibility since it supports DP signals and will convert HDMI and DVI signals.
Whether you need an active video adapter or passive video cable to connect a monitor to your Windows laptop, MacBook Pro, or Purplelec docking station, your choices in accessories may impact the reliability of your signal. Professional accessories from brands you trust are recommended since they have been tested for compatibility and longevity.
Some laptop docking stations have both DP and HDMI ports to allow additional flexibility when connecting to different setups. The types of video ports available on your monitor may vary, therefore these options ensure that you can get connected in different scenarios.
The DP or DP++ icons next to the video ports on your laptop or docking station let you know what technology your device supports and what cable or adapters will be needed to connect your monitor or HDTV.
DP++ ports are more flexible than standard DP ports since they can transmit DVI, HDMI, and DP signals using a passive cable—which is helpful if you connect to both leg-acy and newer monitors. Standard DP ports can also support DVI and HDMI signals but will require an active adapter to do it.
