Tech Support FAQ
Q: Do you have a list of recommended monitor for use with your KVM switches?
We currently do not have a full list of monitors that we can recommend for use with our KVM switches. Generally, we recommend using monitors with good quality cables and avoid having more than 1 connection to the monitor to ensure the reliability of the video. However, there's a third party website that tests different brands and models of monitors, and compiled a list of monitors that may potentially have video issues and talks about why. CLICK HERE for the website.
Q: Are there any docking station you can recommend for use with your KVM switches?
Yes, we've compiled a list of docking stations that we've tested and know can work with our KVM switches. Please reference this page for the list. Please note the list will get updated from time to time as we're continuing to test different brands and models of docking stations with our KVM switches.
Q: Why is the video not working and the monitors say "no signal" when I have everything connected to the DisplayPort KVM switch?
A: The following are the methods that can help you fix your DisplayPort no signal issue:
1) Check your DisplayPort cable connection. You may not be aware, but usually the DisplayPort no signal issue comes from improper cable connection. You have to ensure that the connector has been plugged into the port correctly and it cannot be pulled out too easily. You can unplug an re-plug the DisplayPort cable connection. Try pushing the connector further until you feel the pointy bits on the plug lock it in so that it is difficult for you to pull it out.
2) Restart and reconnect your devices. Restarting and reconnecting your devices is something that you should definitely give a try. It is a simple but sometimes effective way to fix the issue. To perform this method, please follow the steps below.
a) Completely turn off your computer and monitor and unplug their power cables.
b) Unplug their DisplayPort connection.
c) Leave them for a couple of minutes.
d) Connect the DisplayPort cable back to the computer and monitor.
e) Plug the power cables back and power the devices on.
3) Update graphics card driver. Sometimes the DisplayPort no signal issue may result from faulty and/or incompatible graphics driver. You should make sure the driver of your graphics card is up to date to fix problem of this kind.
One easy and credible method to deal with drivers is to use Driver Easy.
Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.
You can download and install your drivers by using either Free or Pro version of Driver Easy. But with the Pro version it takes only 2 clicks (and you get full support and a 30-day money back guarantee):
a) Download and Install Driver Easy.
b) Run Driver Easy and hit Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
4) Test with another cable or device. Your Display no signal problem may be a hardware issue. You can test your DisplayPort connection with another DisplayPort cable or even with another computer or monitor with DisplayPort. Check and see if the trouble comes from the cable or from the ports.
If it is your computer or your monitor that is causing trouble, and if they are under warranty, you can contact the manufacturers of your devices for further assistance. They can help you identify the cause of your problem, and have your devices repaired or replaced.

Q: Why is the video no longer working after I've changed out one of the connected computers to the KVM switch?
A: It's recommended that the user reset the KVM switch after change out a connected computer and/or monitor. The KVM switch will need to find the correct EDID information for the new device in order for the video to work.

Q: Why is my keyboard and/or mouse isn't working when connected to the KVM switch?
A: Please make sure the driver for the keyboard and/or mouse are up to date on all of the connected computers. The keyboard and/or mouse can encounter errors if the drivers are different versions between the computers. For wireless keyboard and/or mouse, make sure the battery is fully charged and there aren't any possible source of signal interference nearby.
Additionally, make sure the USB type A to type B cables are firmly connected between each of the computers and the KVM switch.

Q: Are the ConnnectPRO dual monitor KVM switches able to display different video sources at the same time?
A: Yes, our KVM switches are able to do that. The instructions for enabling/disabling that feature is included in the user manual for the KVM switch.
-----
Q: Are there any firmware updates available for the ConnectPRO KVM switches?
A: Yes. However, it's recommended to leave the firmware as is if the KVM switch is working correctly. If you run into an issue with the KVM switch, then please contact our support team. The support team will assist you with the troubleshooting, and help you determine if a firmware update is necessary for the KVM switch.
-----
Q: Why are all of the lights on the Hot Keys select section on the KVM switch flashing on and off repeatedly?
A: This is caused by either the power source being unstable, or the KVM switch is receiving insufficient power. Unplug the power cable for the KVM switch from the power socket, and plug the power cable to another available power socket.
-----
Q: Why is there a serial port on the KVM switch? What is that for?
A: The serial port on the KVM switch has two purposes. One is for checking/updating the firmware of the KVM switch. The other is for daisy chaining another ConnectPRO KVM switch to allow the setup to support more than 2 monitors.
-----
Q: Can I connect a gaming console such as xBox, PlayStation, etc. to the KVM switch?
A: No. KVM switches were not designed to work with gaming consoles, so it'll not work correctly with gaming consoles.
-----
Q: I've noticed the ConnectPRO KVM switch is powered on even though I did not have the power cable connected, is that normal?
A: Yes, that is normal. The KVM switch does receive some power from the USB cables that are connected between the KVM switch and each computers. However, we recommend connecting the power cable to the KVM switch to help the KVM switch to reliably power all of its functions/operations.
-----
Q: Can I connect a webcam to the KVM switch and share it between all of my connected computers?
A: Yes, you can. Please do make sure the driver for the webcam is up to date on all of the connected computers. Otherwise, the webcam can stop working correctly after switching between channels due to errors caused by differences between the driver versions in each computers.
-----
Q: My Mac stopped working when connected to the KVM switch after I've updated the mac OS, what do I do now?
A: If you currently own an Intel based Mac, then we do not recommend updating the macOS to the new Ventura macOS. The new command set in the Ventura macOS will cause any externally connected device, such as docking station and KVM switches, to not work correctly. There are many users online have complained that the new Ventura macOS caused their Macs to stop working with their external devices.
Links to a couple of online blogs that discuss the shortcomings of the Ventura OS update:

If you have already done the update, then we'd recommend to try to roll back the update to the previous version instead.
