Frequently Asked Questions

Troubleshooting

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.

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:

  • Replace Video Cables with high-quality Video Cables (e.g. upgrade DisplayPort 1.2 Cables to DisplayPort 1.4 Cables).
  • Use shorter Video Cables to reduce signal attenuation.
  • When possible, remove Video Adapters to use native Video Connection Types (e.g. go from VGA to VGA, or DisplayPort to DisplayPort)
  • For DisplayPort Monitors, try changing the DisplayPort Version on the Monitor. For information on how to change your Monitor Settings refer to the Manual from the Monitor Manufacturer.
  • Update the Drivers for the Computer’s GPU to the latest available from the Monitor Manufacturer.

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 cables

  • KVM switch

  • 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. 

  • To determine if a specific cable is the source of the problem, switch the cables that connect the KVM switch to the computers to one working port and computer, and one port and computer that is not working. Keep the computer plugged into the same ports and only switch the cables. If the issue persists when you switch cables, the issue may be with the cable itself.
  • To determine if the problem is between the computer and the KVM switch, using the same cables, connect the KVM switch to one computer that is working and one computer that is not working. If the issue persists when you switch computers, follows the issue may be with the computer and the KVM switch.
  • Try reinitializing the KVM.  This is done by following the setup instructions on the website.
  • To determine if the KVM switch is the source of the problem, if you have another KVM switch, disconnect the current KVM switch and connect the second KVM switch.

If the keys on your keyboard are repeating, complete the following:

  1. If the KVM you are using has USB ports, you can move your keyboard to the USB hub port on the back of the KVM (the USB hubs are marked).

Note: When you move the keyboard out of the keyboard port, you will not be able to access the hotkeys.

  1.  You can adjust the typematic rate in your operating system’s settings. Depending on the version of Windows you are running, you can adjust the typematic rate by doing one of the following:
    • Click Control Panel > Keyboard > Speed. Adjust the repeat delay and repeat rate until the keys no longer repeat.
    • Click Control Panel > Hardware and Sound > Devices and Printers. Right-click Keyboard Settings. Adjust the repeat delay and repeat rate until the keys no longer repeat.

Before You Buy

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 KVM switches. (e.g. SV231USB)
  • Cable KVM switches. (e.g. SV211USB)
  • Multi-Monitor KVM switches.  (e.g. SV231DDUSB)
  • IP KVM switches. (e.g. SV841HDIE)

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.

  • How many computers do you need to control?  Purchase a KVM switch that supports the number of computers in your setup.
  • Which video connections do your computers and display(s) support?  It is best practice to use the same video connections wherever possible.
  • Will you be using a PS/2 or USB mouse and keyboard?
  • Do you need multiple monitor support?  Ensure every computer can support the number of monitors you are looking to use in your setup.
  • Do you need audio support?
  • What resolution(s) do you want your display(s) running at?  The KVM switch must support the resolution(s) you want to use.
  • Would you like hotkey support?  Some KVM switches support the use of hotkey combinations to complete tasks such as switching between computers.

There are a couple of other important things you may want to take note of:

  • Some KVM switches require proprietary cables to function.  These KVM cables may vary by each KVM switch.  For StarTech.com KVM switches that require proprietary cables, the KVM switches will either come with these cables, or they will be listed in the Accessories tab on the individual product pages.  For more information, see our video dedicated to KVM switch cables.
  • Basic mice and keyboards are recommended for use with KVM switches.  Wireless, gaming or combo mice and keyboards (mice and keyboards that use a single USB connection / receiver for both units) can cause performance issues, and in general, are not supported for use with KVM switches.

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:

  1. Check the Technical Specifications tab on the individual product pages for What's in the Box.  This section lists everything that comes with your purchase, and your KVM switch might come with the cables.
  2. Check the Accessories tab.  This section lists potential accessories for the product you are looking at.  StarTech.com will list the appropriate KVM cables for the KVM switch here. 
  3. Check the Gallery and look at a picture of the back of the KVM switch.

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.  

Installation

  1. Turn off all of the computers and monitors that will be connected to the KVM switch.
  2. Connect the power adapter to the KVM switch.
  3. Connect the video cables from your monitors to the console video port on the KVM switch. 
  4. Turn on the monitors.
  5. Connect your keyboard and mouse to the console PS/2 or USB ports on the KVM switch.
  6. If you have not done so already, change the KVM switch to focus on port 1.
  7. Connect the video cables from PC1 to the KVM switch.
  8. Connect the PS/2 or USB cables from PC1 to the PC1 PS/2 or USB ports on the KVM switch.
  9. Turn on PC1. You should see the computer load the operating system that you are using on PC1.
  10. Make sure that the mouse and keyboard can control PC1.
  11. Repeat steps 4 to 8 for each additional computer that you want to connect to the KVM switch. Leave the computer in focus until you make sure that the mouse and keyboard can control the computer in step 8.

Common Issues

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:

  • A DisplayPort EDID emulator can be connected between the computer and the DisplayPort KVM Switch. The DisplayPort EDID Emulator maintains the DDC communication to the connected computer, which prevents the computer from reverting to a more basic display configuration.
  • In Windows this can be worked around by pressing “Windows Key + m” prior to switching and “Windows Key + Shift + m” when you have returned to that Computer.

really terrible

By: jacki - 10/18/2017
I have 2 computers and 2 monitors. I use this at work. whenever I switch between the two computers, i have to press several times to switch between the two. and it works intermittently. I came here to see if there is any firmware but none to be found. Also, when toggle between the computers, the keyboard doesn't recognize intermittently. we're i.t department. we have lots of keyboard to be tested. All of our staff has this and they all have exact same issues. I highly not recommend this.

Great value KVM - Perfect for Macs!

By: SteveI - 04/28/2018
GREAT PRODUCT - I was very pleased to find this KVM with Mini DisplayPort and USB for my two Macs. It works smoothly and transparently with a Mac Mini and MacBook Pro (2014) and Apple aluminum keyboard. Good value for around $100 street price. The KVM is solidly built with a metal case. Three USB device ports It does need to be reset every few months. Using it all day, every day that's not much to ask. GREAT SERVICE - After 22 months, one of the ports stopped working. StarTech technical support walked through troubleshooting with me via email. When we found the unit was defective, they sent a replacement under the two-year warranty with minimal hassle. I will definitely choose StarTech for my future needs.

Handy KVM

By: C Reyes - 04/30/2018
Bought this over two years ago. The body feels high-quality and sturdy. So far, I've had no issues and often forget it even exists! The one wonky behavior is switching between computers but can tell it's due to daisy chained DisplayPort 27inch monitors, Win10 has improvements for this. The KVM itself is solid and supports DP 1.2.

Well, one of the 2 works . . .

By: MarcoC - 11/13/2018
Despite my best efforts, computer #1 always detects as 1024 x 768 resolution (it's a super-high-end screen running the most recent NVIDIA powerhouse graphics card so, erm . . . yeah, I think this could do better).

works well, easy to set up

By: yet_another_john - 07/26/2019
just installed this, connecting two Dell Precision T3500 computers to a 30" Dell Monitor (2560x1600 resolution). Switching between the two computers is very easy and quick. The housing is nice, sturdy metal and doesn't slide on the desk when you press the selector switch. Keep in mind that your power saving settings may affect the one computer you are not accessing, it might go to sleep. The image on the monitor is clean and rock steady. Windows does make the funny sound it makes when a USB device is connected and disconnected, but that is not the fault of the KVM switch, just a Windows thing.
