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.

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

  1. On your keyboard, press the Windows key + X and select Control Panel.
  2. Click Appearance and Personalization, then click Display.
  3. Click the Resolution or Adjust Resolution option from the left column, which will display your monitors as numbered icons.
  4. Click Identify to display the numbers on each connected monitor, showing how the operating system has assigned their positions.
  5. Click and drag the monitor icons to best match your physical setup.
  6. Click OK to apply the changes and close the window.

Windows 7 and Windows Vista

  1. Click the Start button and select Control Panel.
  2. Click Appearance and Personalization, then click Display.
  3. Click the Resolution or Adjust Resolution option from the left column, which will display your monitors as numbered icons.
  4. Click Identify to display the numbers on each connected monitor, showing how the operating system has assigned their positions.
  5. Click and drag the monitor icons to best match your physical setup.
  6. Click OK to apply the changes and close the window.

  1. Click the Start button and select Control Panel.
  2. Double-click Display.
  3. Click the Settings tab, which will display your monitors as numbered icons.
  4. Click Identify to display the numbers on each connected monitor, showing how the operating system has assigned their positions.
  5. Click and drag the monitor icons to best match your physical setup.
  6. Click OK to apply the changes and close the window.

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.

To output 4K to a DisplayPort display at 60Hz your monitor must support the resolution and refresh rate. If your monitor supports 4K at 60Hz (DP1.2 or higher) you may also need to set the monitor to work at 60Hz.

To resolve this issue, use the buttons on your monitor to change the DisplayPort settings to DP1.2. For more information about changing your monitor settings, refer to the website of the manufacturer of your monitor.

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.

Not really Mac Compatible

By: sefanzed - 05/25/2014
I bought this after speaking with Startech's support team, which while they didn't really know a lot about this product, were generally helpful. First the Good news. Supports DisplayPort to legacy adapters very well. I'm running a 30" Apple monitor (w/powered adapter) and 27" hdmi (passive adapter) between two macs. No video problems. Now the Bad news: The unit doesn't recognize a mac keyboard, (according to StarTech support "no KVM does")so in addition of not being able to use the HOT key switching, the unit won't even pass keystrokes from the dedicated keyboard usb in to either or both machines (I got inconsistent results from this- I tried 2 units). Fortunately, the hub works just fine, so if you place the unit where you can reach it, it will perform well (just don't use the dedicated keyboard or mouse inputs). The unit is well priced at amazon and rakuten, and compared to other solutions (which also have their own issues) it's at least workable. Would hope that their Asian development partners start supporting Macintosh products. There are more than just cheap PC's out there!

TO "sefanzed": Try the Microsoft Wireless Keyboard 3000 and Mouse 5000. I bought it as a set. It is one of the few that are compatible for BOTH PC and MAC. I have connected to both. Now I will buy the KVM and a Macbook Air Thunderbolt Dock.

Poor Device

By: PeteDarton - 01/18/2016
Been looking after lots of these devices for several weeks now and no end of problems. Problems: have to type each key twice at bios level, screens go blank when lost focus or go into powersave mode. Have to switch PC off/on to get video output again. remote desktop comes inactive at times when trying to connect to remote server, have to close down and reopen. These are just a few of the issues, very poor performance for what should be a simple product.

Frustrating to use, bad keyboard passthrough

By: fleebness - 08/07/2016
After installing this, I noticed serious problems typing at normal speeds. This KVM will either drop or transpose characters as you type them, for some peculiar reason. As a consequence, I find myself plugging my keyboard into the machine I wish to use manually, almost defeating the point of having this. Switching between machines will work, but perhaps because they do not feed any information between the machine from which you've switch and the now-missing displays, something seems to get reset, and you find yourself having to fiddle with settings when you return. It does maintain good video quality (otherwise), and not a problem with the mouse. The keyboard issue is serious enough to warrant a 2 star rating instead of the 4 stars I would otherwise give this.

Does exactly what I need it to. No muss, no fuss. Took 5 minutes to hook up, and it's worked perfectly ever since.

Product as described. Works good.

By: jbeck - 07/17/2017
I would recommend this to anyone with dual monitors and two pc’s. The only issue I had was that Windows 7 kept adjusting the displays when I switched between computers. It was a real annoyance to find all my windows, icons and screen resolutions messed up every time I switched. I finally after about a week of annoyances found a setting in my catalyst control center to disable display polling which fixed the problem for me.

Very mixed feelings with this...

By: BillRyan - 09/14/2017
First, let me note I received this item in exchange for an impartial review. That said, please pay attention and know what you want and need before buying this. DisplayPort is NOT HDMI. They look similar but aren't and unless you have DisplayPort, you'll need an adapter which will delay things. Past that, this is as easy to use as any other KVM StartTech offers. It's not a low end KVM. This is serious KVM for people that want and need a professional product. The scenario this solves is simple - Multiple computers, typically a Desktop and a laptop or two towers and one primary monitor, mouse, speakers and peripherals that you want to share with the two computers. Very simple solution to an annoying problem. The construction is really solid as I said above, it's durable and strong, allows some air flow so heat isn't a huge issue and everything fits pretty as well as it could. Unlike the other KVM switches I've got here, this one started out working great and then got really sketchy. I see a few others noted a few problems. I'll just say I've had the same ones almost identical. HOWEVER, it's easily fixed, very intermittent and is seldom a very big problem. To fix it you hit the button twice. Yet it still does seem weird and my only concern is that it seems to have gotten worse over time, the quick fix may not continue working. As long as you know what your components are, understand DisplayPort vs HDMI, have the adapters if you need them, you'll have this thing out of the box and working in a few minutes. I was hoping I had a bad unit until I saw a few other people post about it. Time will tell.

Good product, with good tech support

By: GuyC - 05/04/2018
I bought one of these and it was defective in an obscure way. Tech support were patient and diagnosed it, then sent a replacement. The new unit works brilliantly. It manages sound and a large stack of USB devices without a hitch.

Frustrating

By: IT Support Tech - 09/20/2018
Support about 40 of these and work most of the time but have a high level of failures from keyboard/mouse not working to screens not always detecting. Have to buy several replacements each year. Wish there was an alternative on the market

The only thing that works for me...regrettably.

By: BjR69 - 02/29/2020
I've had this for over a year and it behaves HORRIBLY when recovering from sleep and the supposedly USB2.0 hub is practically useless. For both of these situations, I believe that a firmware update would/could help, but...I don't see that happening. Still for my dual DP with two laptop setup, this is the only viable option. Did I mention it's WAY too expensive for what it provides? :-(
