Product ID: SV231DPDDUA2
This dual DisplayPort KVM switch combines next-generation digital display standards with seamless KVM control. The 2-port KVM switch features audio and USB peripheral support along with dual-display capability, which makes it easy to create a multimedia workstation that can switch between two dual-head or twin DisplayPort systems.
With support for two DisplayPort video inputs and two different computers, this KVM switch helps maximize productivity.You can access multiple computers, giving you the freedom to multitask and increase your productivity. Each of the DP ports supports resolutions up to 4K for maximum screen viewing space.
You can also use low-cost adapters to achieve a dual-monitor setup using your computer's secondary HDMI or DVI port.
The dual DisplayPort KVM switch supports resolutions up to Ultra HD 4K at 60Hz, and can drive two large DP displays with ease. This makes it the ideal solution for creating workstations where high-quality imaging is critical, such as for graphic design.
The KVM switch features auxiliary 3.5 mm audio ports that let you share independent analog audio, from each of your connected computers, with your desktop speaker set.

Monitors may begin flickering when they receive a signal of insufficient quality. There are a few potential fixes available that will help to improve the signal quality in order to eliminate flickering:
There are some quick tests that you can perform to rule out potential issues. Start by turning off all of the connected computers and peripherals, unplugging everything from the KVM, including power, and leaving it for 10 seconds. Then connect everything to the KVM following the procedure in the following FAQ: https://www.startech.com/faq/kvm-switches-setup.
You can test to make sure that the following components are working correctly and are not the source of the issue:
Video source (such as a DVR or computer)
Video destination (such as a monitor or projector)
Note: When you are testing your setup components, it is recommended that you avoid using any video adapters. For example, if you are converting a VGA source to HDMI to be used with an HDMI extender, you should test with an HDMI source.
To test your setup components, try the following:
Use the video cable, KVM switch, video source, and video destination in another setup to see if the problem is with the components or the setup.
Use a different video cable, KVM switch, video source, and video destination in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.
When you test your cables, it is recommended that you do the following:
Test each cable individually.
Use short cables when you are testing.
When you test the video source and video destination, it is recommended that you do the following:
Remove the KVM switch from your setup and test to make sure that the video source and video destination work together without the KVM switch.
Test to make sure that the video source and video destination work together at the resolution that you want to use.
Note: In order for your setup to work properly, the video source, KVM switch, and video destination all need to support the resolution that you are using.
There are four troubleshooting actions that you can try if some but not all of the ports and your computer are working with the KVM switch.
If the keys on your keyboard are repeating, complete the following:
Note: When you move the keyboard out of the keyboard port, you will not be able to access the hotkeys.
In order for your mouse to move properly between your monitors you must rearrange your monitors in Windows to match the physical location of your monitors on your desk. To do so, complete the following based on your operating system:
Windows 10 and Windows 8
Windows 7 and Windows Vista
To mirror the image from your primary monitor instead of extending your desktop, refer to the following FAQ: http://www.startech.com/faq/Windows_Mirroring_Monitors
To output 4K to a DisplayPort display at 30Hz, your monitor must support the resolution and refresh rate. If your monitor also supports 4K at 60Hz (DP 1.2 or higher), you may also need to set the monitor to work at 30Hz.
To resolve this issue, use the buttons on your monitor to change the DisplayPort settings to DP1.1. For more information about how to change your monitor settings, refer to the website of the manufacturer of your monitor.

KVM stands for Keyboard Video Mouse and KVM switches allow you to switch the use of a keyboard, display and mouse between multiple computers. KVM switches also commonly let you switch audio and USB devices between computers.
There are different types of KVM switches as well.
Standard box and cable KVM switches are a simple way to switch the use of a keyboard, display, and mouse between multiple computers. Multi-monitor KVM switches allow you to switch multiple displays between computers, and IP KVM switches allow you to remotely control the KVM switch and connected computers over a network.
Here are some important things to consider before purchasing a KVM switch.
There are a couple of other important things you may want to take note of:
It can be difficult to tell which ones are right for the KVM switch you are interested in. How can you tell which KVM cables you require? How can you tell if a KVM switch requires proprietary cables? How do these cables work?
Standard KVM Switches and Cables
Note: You will need one bundle of KVM cables per computer you want to connect to the KVM switch.
Standard KVM switches have no special cable requirements. If you have spare video and PS/2 or USB cables, you can use them to hook up the KVM switch to your computers. StarTech.com still sells KVM cable packages, but they are just for the convenience of buying them in bundles and usually involve some savings. Keep in mind that even if you have some of the cables you need, it still might be advantageous to buy the bundle.
KVM Switches with Opposite Gender Video Connections
Some KVM switches use male video connections for the computers and female video connections for the console ports. In this case you simply need a video extension cable, or a KVM cable package appropriate to the KVM switch. This is so you cannot accidentally plug cables from your computer into the console ports.
KVM Switches Requiring Proprietary Cables
KVM switches can also use proprietary KVM cables to connect to the individual computers. This is often done with larger KVM switches and KVM switches intended for a server environment. These cables use a proprietary pinout which does not conform to the video standard in use, as the cable carries both the video and PS/2 or USB data along a single cable.
If you are unsure whether or not you need special cables, complete the following:
Note: If there are no PS/2 or USB ports on the back of the KVM switch other than for the console, you will require proprietary cables.
If at this point you require further assistance in deciding which cables to purchase with your StarTech.com KVM switch, contact our technical support team.
Whether a specific mouse or keyboard will work with StarTech.com KVM switches can depend on the type of mouse or keyboard you use. Any mice with additional functionality or keyboards that are not standard 104 key keyboards could cause issues. This includes wireless, gaming, combination (one USB receiver for both the mouse and keyboard), and Apple keyboards. We recommend that you use a standard wired mouse and keyboard with our KVM switches, especially when you troubleshoot issues.
If you cannot get a specific mouse or keyboard to work with your KVM switch, connect the mouse or keyboard into the USB hub ports, if available (they are marked on the back of the KVM switch). If the KVM switch has hotkey functionality, you will lose the functionality when using these hub ports.
The Display Data Channel (DDC) communication from each connected computer can be disrupted when the focus of a KVM switch is switched between computers. This causes the computer to revert to a basic display configuration. In which any windows open may resize and/or move to a single display. This behavior is common among high-resolution or multi-display DisplayPort KVM switches and is not exclusive to StarTech.com products.
To avoid this behavior:
The beeping sounds cannot be disabled. They help confirm that a successful or unsuccessful hotkey command has been entered. Many people position their KVM switch out of sight. As a result, this feature saves time by not having to check the LEDs or press the physical buttons on the KVM switch.
