Frequently Asked Questions

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.

Troubleshooting

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.
  1. Ensure the video & USB cables are connected between each computer and the KVM switch
  2. Safely power off all computers.  Unplug everything from the KVM switch and connect one computer at a time, swapping the inputs previously used (e.g., the computer connected to PC2 now connects to PC1). Power on each computer and confirm functionality before connecting the next one to the KVM switch. 
    • If using a KVM switch that supports multiple displays, ensure all video connections from the computer are from either the video card or motherboard, both cannot be used simultaneously on most systems.

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.  

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.

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.

Common Issues

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.

Good KVM but no 4K @60Hz

By: Bob Rysome - 03/05/2016
Bought this item awhile ago as part of a general system swap to use DisplayPort. It has been working fine with a series of 1k and 2k panels without trouble at max res. and frequency. As per usual - StarTech make reliable kit that is well made. Anyway, just got a new 4K panel and thought I would connect it up. It seems that the unit is only DisplayPort 1.1 compliant. This means that it will not do 4k @60Hz. It will only do a max of 4k @ 30Hz. Therefore, looking for an alternative solution to it at the moment. Unfortunately the 4k market for KVMs is a little stale at the moment in regards to DisplayPort. Would wish that StarTech would come out with one that supports 4 ports and DisplayPort 1.2 (at the very least - the standard has been around since 2009).

Does what I need it to without issue.

By: Mike B - 05/31/2017
Two weeks in and it is working flawlessly. No software setup, just plug in the two laptops and use it. I'm not using audio and not worried about 4K. Just using the basic keyboard, video and mouse. One difference is that my keyboard has the old PS/2 connection. Using a PS/2 to USB converter does not cause any issues with the KVM as I've seen on others in the past. A number of KVMs have issues with certain versions of Windows O/S. I have one laptop at Win 7 and the other at Win 8. No issues whatsoever. Will eventually put a third laptop (Win 10) and a desktop (Ubuntu 16) on the KVM as well.

Fails to do 1080p

By: BrandonG777 - 08/14/2018
Failed to output 1080p switching back and forth between sources. I can switch the refresh rate and the KVM will work but as soon as I switch inputs and back again it stops working until I change the refresh rate agian. I've used StarTech KVMs without too many issues, from VGA to DVI flavors and this is the first to not work consistently.

Flashes on 3 different HP monitors

By: KenRogrsRoasted - 08/30/2018
I bought 2 to do multiple setups for Deployment. Both have issues: flashing the screen (mostly off) and not catching a signal on start up so never seeing a screen. Lastly one of the two only works with two or less of the ports connected. I cannot find a firmware update or support for these issues.

Brian, Customer Support on 03/09/2018 17:05:46
Thanks for leaving your feedback on our SV431DPUA KVM switch. We're sorry it didn't work well and would like to offer some help. Some 4K DisplayPort monitors can be problematic with extenders or KVM switches between them and the computer. We'd like to look into this further, please contact us by phone or live chat and mention this review.

Not working with Ubuntu

By: Julien - 11/08/2019
I have 2 computers on Ubuntu, when I start the computer I have my screen, but if I switch to the second one and I switch back to the first, I don't have the screen anymore because the X server crash because the KVM doesn't respond to the displayport during switch... The KVM does not respect the display port standards...

Matt, Customer Support on 11/11/2019 17:01:37
Thank you for your feedback Julien. We understand your disappointment in the performance of our SV431DPUA and we'd like to help troubleshoot this issue. We have a FAQ available regarding the disconnection of displays when using DisplayPort KVM switches here: http://www.startech.com/faq/Windows_Resize_KVM_Switch#SV431DPUA. This FAQ is referencing behavior in Windows but if the Ubuntu computer has difficulties when there isn't a display connected this could be what's causing the problem you're seeing. One fix, as recommended in the FAQ, is using a DisplayPort EDID emulator, of which both software and hardware versions are available. If you have any questions or require any assistance, please feel free to contact us at www.startech.com/support. Our Technical Advisors are available 24 hours a day, 5 days a week to provide support.
