A DisplayPort KVM extender is a device that performs the functions of a traditional KVM extender via a DisplayPort connector. The device helps to transmit signals over longer distances. Using matrix-compatible extenders to transmit DisplayPort signals, multiple computers can be controlled over a longer distance. With the DisplayPort KVM extender, all end devices are controlled centrally.
Typically, a DisplayPort KVM extender consists of a transmitter (CPU) and a receiver (CON). The receiver is connected to the display devices, while the transmitter is connected to the computer sources. The signals are transmitted via DisplayPort over a connection interface such as a Cat-6 or fiber optic cable.
The DisplayPort KVM extender allows you to operate the connected computers with a single keyboard, mouse and monitor, even over long distances.
Newer versions like DisplayPort 1.2 and 1.4 offer very high bandwidth for data transfer. The connections support higher refresh rates and color depths. It is also possible to transmit high-resolution video signals, including 4K.
The DisplayPort standard supports a wide range of video and audio formats, including the transmission of high-quality multi-channel audio. In addition, it can be used to connect monitors, TVs, projectors, and other display devices.
The function of Daisy-Chaining is supported by DisplayPort. This standard allows multiple devices to be daisy-chained using a single DisplayPort connection. This makes it easier to install hardware and allows multiple monitors to be controlled from a single port.
DisplayPort has built-in security features such as Content Protection (HDCP) and DisplayPort Content Protection (DPCP). These features protect content from unauthorized recording or duplication. Even long-range connections via a DisplayPort KVM extender are thus shielded from external access.
Another advantage is that the DisplayPort standard is backward compatible. Newer connections can be used with older devices and cables with lower bandwidth without any problems.
All this makes DisplayPort a popular choice for professional applications.
A DisplayPort KVM extender is used where outsourcing and remote operation of computers is required. The DisplayPort connection provides the basis for transferring particularly large amounts of data within a very short time. The DisplayPort 1.4 transmits up to 32.4 Gbit per second.
To ensure transmission over long distances, a KVM extender is required. These are some examples of where the DisplayPort connector can be applied to a KVM solution.
Data centers and server rooms: The DisplayPort KVM extender enables the outsourcing and control of computers. Administrators can access data centers and server rooms without having to be physically on-site.
Media Production and Broadcast: To create and edit media content, powerful workstations and servers are often used in the media and broadcast industry. The DisplayPort KVM extender makes long distance editing possible despite high data volumes.
Industrial Control Rooms: The DisplayPort KVM extender establishes remote access to computer systems in industrial environments. Machines and production processes can be monitored and controlled from a control room. This makes production processes more efficient and flexible, as it is possible to intervene immediately in running processes.
It is possible to connect two displays with DisplayPort. Multi-Stream Transport (MST), a feature of DisplayPort that enables Daisy-Chaining. To connect and use multiple displays at the same time, you can create a chain of DisplayPort devices with extenders.
Is DisplayPort better than HDMI?
As a rule, DisplayPort has a higher bandwidth than HDMI. This allows it to transmit much higher resolutions and frame rates. Also, DisplayPort is able to support features like Daisy-Chaining and Adaptive Sync.
Why can't HDMI and DisplayPort be connected?
HDMI and DisplayPort signal standards have different protocols. Both standards are not natively compatible and use different electrical signals and data formats. Direct connections between HDMI and DisplayPort usually do not succeed without an active converter or adapter.
The best way to talk about complex topics is in person. Via chat, e-mail, phone or in a personal demo remote or on-site.
