The AdderView Pro AV4PRO-DP is designed to enable four computers equipped with Display Port technology to be controlled from a single KVM console. This unit makes use of Adder's True Emulation Technology which enables USB HID, low and full speed, devices to be continuously emulated to each computer providing instantaneous and reliable hotkey switching. Furthermore, this AdderView Pro 4-port includes two independently switchable USB 2.0 channels and an audio channel, giving the user the flexibility to attach your keyboard and mouse peripherals to different computers. An 'Options' port enables this unit to be remotely switched using a 4 button switch unit (RC4).

Two AV4PRO-DP units can linked together to create a 4 Port Dual Monitor DisplayPort KVM switch by using a VSC41 synchronising cable.

Adder AV4PRO-DP Features

  • Adder AV4PRO-DP DisplayPort 1.1 Video Support

    High definition DisplayPort 1.1 video support

    The AV4PRO-DP is DisplayPort 1.1 compliant (4 lanes at 2.7Gb/s). DisplayPort's high performance is important for enabling new digital display experiences. For example, DisplayPort can easily support high end monitors featuring 2560x1600 resolution at 60Hz refresh rate and 10 bits per color, 1920x1200 resolution at 120Hz refresh rate, and Full HD monitors at 1920x1080 resolution and 60Hz refresh rate at 12 bits per color without latency, all over standard cables.
  • Adder AV4PRO-DP supports modern keyboards & mice, graphics tablets, jog shuttles, joysticks, and 3D explorers.

    True USB 2.0 emulation

    Unlike most KVM switches, which only support the most basic keyboard and mouse features, Adder's revolutionary 'True Emulation' allows you to use the extra function keys, wheels, buttons and controls that are commonly found on modern keyboards and mice. You can also use any other USB interface device including graphics tablets, jog shuttles, joysticks, 3D explorers, and wireless bluetooth keyboard & mouse*.

  • Adder AV4PRO-DP - Independent USB & Audio device switching

    Independent USB & Audio device switching

    The AdderView Pro AV4PRO-DP includes two independently switchable USB 2.0 channels and an audio channel, giving the user the flexibility to attach selected peripherals to different computers. For example, use the KVMA console to work on one computer whilst your USB peripherals are connected to other computers and your speakers are playing music from yet another.

  • Adder AV4PRO-DP - transparent USB 2.0 Hub with broad high speed device support

    Broad High Speed device support - Transparent USB 2.0 Hub

    An integrated transparent 2-port USB 2.0 hub allows a vast range of USB devices can be connected to the AV4PRO-DP from non standard keyboard / mouse devices to flash drives, printers and scanners.

  • Adder AV4PRO-DP

    Fast & Reliable Switching

    Country code reporting, and continuous keyboard and mouse emulation ensure faultless operation. The USB 2.0 switching action has also been carefully engineered to ensure maximum computer reliability when connecting and disconnecting USB devices.

  • Adder AV4PRO-DP channel selection via remote

    Channel selection options

    The AdderView Pro AV4PRO-DP can be switched using the front panel buttons, selectable keyboard hotkeys, 3 button mice, an On-Screen-Display (OSD), or using simple ASCII codes via serial RS232. Optionally, you can also use the RC4 remote switch to make your selection. These switching options allow you to rapidly reassign connected devices to any of the connected computers.

  • 2x Adder AV4PRO-DP linked as a 4-Port Dual Monitor DP KVM Switch

    Dual-Monitor configuration

    Two AV4PRO-DP units can linked together to create a 4-port dual monitor DisplayPort KVM switch by using a VSC41 synchronising cable.

Question: I would like to purchase a product that allows two PCs to be controled by one monitor, one keyboard, and one mouse. Is this the appropriate product? Also who is the KVM distributor in Spain?
Answer: You are describing what is called a KVM (Keyboard, Video, Mouse) switch, of which the AV4PRO-DP-US is one. Whether it is the appropriate solution for your situation depends on a number of factors including the type of display being connected and type of peripherals used.

This particular KVM is for switching 4 computers using a USB keyboard and mouse and a DisplayPort video connection. Depending on your need, there may be less expensive solutions available. If you are not sure of the exact product you require, give us a call at 1-877-586-6654.

Question: I would like to purchase a product that allows two PCs to be controled by Two monitor, one keyboard, and one mouse.Can you help me to choose appropriate product
Answer: Thank you for your inquiry. Your choice of KVM switch will depend largely on the peripheral connections that you require. You will be looking for a 2-port KVM that supports dual monitors. The next question is, what type of video connection do you need (DVI, VGA, HDMI, DisplayPort) and what type of keyboard and mouse connection you need (USB, PS/2).

A selection of dual monitor KVMs can be found here: If you would like additional help in selecting an appropriate solution, please give us a call at 1-877-586-6654.

Question: Does this work better at DisplayPort switching than the Aten CS1944?
Answer: Adder switches are high quality, and many consider them to be superior. Radiologists will often go with Adder over other brands for the high resolution and image quality available through the Adder switches.

Question: I would ask the same question someone asked about a different model: Are the connections to the computers persistent? In other words, if the kvm is switched to system 2 from system 1, will the OS on system 1 still see a Displayport monitor still connected?
Answer: Thank you for your inquiry. While this particular KVM provides USB keyboard and mouse emulation, it does not provide continuous EDID or emulation for the monitor. When focus is changed, it will appear as if the monitor has been unplugged from the non-active system. Unfortunatly, this is due to the complexity of the DisplayPort signal.

Question: I have 2 HP Computers that each have a dedicated monitor. I want to be able to switch back and forth from one PC to the other using a KVM switch. I only want one mouse/keyboard for both PC's. I suppose I can either use VGA or display port - if display port provides better quality, I want to use that one.
Answer: Thank you for your inquiry. DisplyPort generally provides higher resolutions than VGA. For instance, this switch can output 2560 x 1920 while the VGA version ( output 1920 x 1440. Outside of the resolution, performance for these two devices should be pretty similar.

If both PC's have there own monitor, another device that may be of interest is the CCS4USB-US Adder Command & Control Switch with free flow technology (a href=''> It allows the KVM focus to be changed by simply moving the mouse over to the next monitor.

Question: Is this a SECURE KVM? IT will be used for government highly sensitive data
Answer: Thank you for your inquiry. This unit is not a "secure KVM" that meets the requirements for NIAP Validation to either EAL4+ or EAL2+ certification levels.

Some certified secure 4-port KVMs are located here: If you would like assistance in selecting your secure KVM, please give us a call at 1-877-586-6654 or contact us through our chat feature. We would love to help.

Question: What refresh rate can this support at 2560x1920?
Answer: Thank you for your inquiry,

The Adder AV4PRO-DP-US supports 2560x1920 resolution up to a refresh rate of right around 50Hz.

Question: I'd like a KVM switch that allows four computers to be control by one keyboard one mouse and allows the four video outputs to go directly to four 4 k screens DisplayPort without going through the 4 port KVM switch?
Answer: Thank you for your inquiry,

It sounds like you may be looking for a 4 Port Keyboard & Mouse (KM) switch such as the Adder CCS-PRO4-US Command &Control Switch? A KM Switch is the same concept as a KVM switch, but without the video signal transmission / switching.
