   • No video
   • Monitor not working
   • Flashing/Blinking
   • Only one computer displays
   • Port # not working

3. Only One Display Is Working

   • Only one display is working
   • Display not working
   • One monitor working only

4. If you have at least 1 video connection from each computer, you can test the KVM’s output to the monitors using Mode 2 feature (each computer on each monitor). Both displays should work when Mode 2 is active, confirming the KVM output is functioning correctly.

5. If only one monitor is working, it is possible that you are missing the second video connection or the dock/adapter being used is incompatible with the KVM environment.

Product Usage Instructions

To use the TESmart KVM switch, follow these instructions:

HotKey Switching
To switch between connected computers using hotkeys:

1. Ensure that your keyboard is plugged into the dedicated Keyboard/Mouse port of the KVM switch.
2. Refer to the hotkey commands provided in the user manual for your specific product model (e.g., PKS0802A10).
3. If the hotkey commands don’t work, try using the Scroll Lock key on your keyboard as the hotkey trigger. If that doesn’t work, try the Right-Ctrl key.

Dual Monitor Setup
If you have a dual monitor setup with the TESmart KVM switch:

1. Refer to the hotkey setup instructions in the user manual to configure hotkeys for dual monitor switching.
2. If the hotkey commands for dual monitor switching don’t work, check if your keyboard has a Scroll Lock button. If it doesn’t, follow the Passthrough Mode instructions provided in the user manual.

Keyboard/Mouse Issues
If you encounter issues with your keyboard or mouse when connected to the KVM switch:

1. Ensure that the USB connection between the KVM switch and your computer is established properly.
2. If you experience erratic mouse behavior, dropouts, or repeating keys when connected to the dedicated mouse/keyboard ports, it may be due to conflicts with gaming peripherals or certain mouse/keyboard brands. Try uninstalling software from brands like Logitech, Corsair, Razer, etc., that may conflict with the hotkey software.
3. If you are using a wireless keyboard/mouse, consider using a USB extender to bring the USB dongle closer to the devices and reduce interference.
4. If the above solutions do not work, use the USB 2.0 port with a powered USB hub as a workaround. Note that this will disable keyboard hotkeys and mouse gesture switching.

Video Signal Issues
If you are experiencing video signal issues with the TESmart KVM switch:

1. Refer to the troubleshooting steps provided in the user manual for specific issues like blank screen, no video, flashing/blinking, etc.
2. If only one display is working, ensure that you have connected at least one video connection from each computer. Use the Mode 2 feature to test the KVM’s output to the monitors. Both displays should work when Mode 2 is active, confirming that the KVM output is functioning correctly.
3. If only one monitor is working, check if you are missing the second video connection or if the dock/adapter being used is incompatible with the KVM environment.

Troubleshooting/FAQ

My hotkey commands don’t work or stopped working

• Make sure keyboard is plugged into dedicated mouse/keyboard ports
• Try using Scroll Lock as hotkey trigger, if not, then Right-Ctrl.

My keyboard does not have a Scroll Lock button

There are two kinds of trigger hot keys in this product, the default is Scroll Lock key, and the alternative is the Right-ctrl key. If Scroll Lock Key has been used for other functions, you can switch the hot key to Right-ctrl by:

• Method 1: 10 seconds after powering on the KVM, press and keep holding the Set button on the front panel until you hear the buzzer is beeping, then restart KVM.
• Method 2: Press Scroll Lock→Scroll Lock→F1, and you will switch the control hot key to Right-ctrl.
  Vice verse, Press Right-Ctrl→Right-Ctrl→F1, and you will switch the control hot key to Scroll Lock.

Keyboard/Mouse Issues

Jumpy mouse | erratic behavior | repeating keys | multimedia keys not working | No mouse | No keyboard

We upgraded this KVM keyboard and mouse compatibility：

• The new generation pass through mode is builded-in and opened by default, which further expands the compatibility of keyboard and mouse and enhance user experience.
• At this time, you can use more keyboard and mouse functions and special functions that are no supported by traditional KVM.

Simplifies user operations：

1. There is no need to turn pass through mode on/off, so there will be no compatibility issues caused by accidentally turn pass through mode off.
2. No longer need to use the hot key to determine whether the mode is turned on.

My Mouse & Keyboard Are Not Working?

First of all make sure you have the USB connection established

If you’re having erratic mouse behavior, dropouts, or repeating keys when connected to the dedicated mouse/keyboard ports, this could be because the dedicated mouse and keyboard ports have EDID programming. This emulation is what allows the switch to receive hotkeys and mouse gestures but conflicts with gaming peripherals and select mouse/keyboard brands.

• Solution 1: We see issues occur sometimes when there is Logitech or keyboard/mouse software (corsair,razer or etc.) installed into the computer. You can search your “Apps & Features” and uninstall this software. This should stop the confliction between the hotkey software and keyboard/mouse software.
• Solution 2: Another possible cause could be IR interference if you’re using wireless keyboard/mouse, since the USB port is in the back of the KVM there could be interference due to distance and the cables. Using a USB extender to bring the USB dongle closer to the devices will strengthen the connection.

If that still doesn’t work we recommend using the USB 2.0 port with a powered USB hub as a workaround. Because the USB port does not have EDID emulation, keyboard hotkeys and mouse gesture switching are not available to devices that use the USB input.

Video Signal Issues

Blank Screen | No video | Monitor not working | Flashing/Blinking | Only one computer displays | Port # not working |

Only One Display Is Working
Only One display is working | Display not working | One monitor working only

1. If you have at least 1 video connection from each computer then using the Mode 2 feature (each computer on each monitor) you can test the KVMs output to the monitors. Both displays should work when Mode 2 is active. This confirms the KVM output is working fine.
2. If you have only one monitor working, it is likely either you’re missing the second video connection or the dock/adapter you’re using is incompatible. Even if the adapter works when not connecting it to the KVM, it is possible that the adapter does not work well in the KVM environment.

Some Suggestions for Troubleshooting：
All input devices need to plug 2 video cables into KVM. All “Display 1” and “Display 2” means the screen printing of KVM.

• STEP 1 — Keep the cables and KVM connection ports unchanged, and then exchange the monitor connect to Display 1 with that to Display 2, and check the working status of them after the exchange.

1. The monitor that work properly before ——> still works properly  

The monitor that cannot work before ——> still cannot work.
That means this monitor is malfunctioning.

2. The monitor that works properly before ——> cannot work anymore.  

Go to STEP 2.

• STEP 2 — Maintain the connection state completed in STEP 1 and do not change the position of the monitors and the ports. Exchange the connection cables(which connect the monitors and KVM), and observe the working status of the monitors now.

1. The monitor that cannot work before ——> work properly  

The monitor that works properly before ——> cannot work anymore That means the cable of this monitor is malfunctioning.

2. The monitor that works properly before ——> still works properly The monitor that cannot work before ——> still cannot work  

That means the KVM is malfunctioning.

Any other questions, please feel free to contact us.

Flashing Monitors/No Display
Flashing Monitor | Snow screen | Blank Monitor|

The following are some common reasons that cause this situation

• Bad Cable- Its pretty rare but sometimes the video connection could fail. Try testing this connection directly to a monitor to confirm the connection works outside of the KVM.
• Bad Port- Either on the KVM or computer side. On the computer side, swap it with another computer if available. On the KVM test the failing port with another computer that is known to be working with the KVM. It the issue is USB(keyboard/mouse) failure, make sure you have the Online Light on, this indicates that the USB connection is active.
• Generic Adapter/Converters- If you are using adapters/converters is the connection stream this is often a point of failure.
• Non-standard Resolution than the Other Working Monitor- Try to change resolution for the problematic monitor to the same as the other working monitor. Its possible that the selected resolution is not supported by the KVM therefore this will result in a blank screen or flickering.
• Docking Station Issues- Its pretty rare to have incompatible docks but it does happen with some older docking stations for example the HP Ultraslim Dock 2013
• Monitor- Make sure the monitor is set to the right input source.

Dual Monitor Display Troubleshooting
Only One display is working | Display not working | One monitor working only

1. If you have at least 1 video connection from each computer then using the Mode 2 feature (each computer on each monitor) you can test the KVMs output to the monitors. Both displays should work when Mode 2 is active. This confirms the KVM output is working fine.

2. If you have only one monitor working, its likely either you’re missing the second video connection or the dock/adapter you’re using is incompatible.
   Even if the adapter works when not connecting it on the KVM, it is possible that the adapter does not work well in KVM environment.

3. If PC 1 works good with both monitors but PC 2 does not then you can swap PC 1 over PC 2 Inputs. If PC 1 works fine on both inputs this confirms the KVM is working fine and the issue is related to PC 2. Could be the port, adapter or dock being used.

Audio Issues

My audio isn’t working | speakers are not working | no audio

How Do I Get the Audio to Work?
Your computer will transmit audio via the video connections, such as HDMI cables.

1. Please confirm what output interface is the computer equipped with? (DVI? HDMI?) If your computer is equipped with DVI output, normally that the DVI output does not carry audio signals, so the audio signal cannot be output to the speaker.
2. If you have an external device plugged into the audio mini-jack, the switch duplicates the audio signal from the HDMI input to the monitor and mini-jack out. After you connect the headset, you need to switch to the computer with the audio device turned on. Only the computer that controls the audio playback will output audio. Generally we just try all of the outputs one of them is correct.
3. If audio is not working, please go to your sound settings and choose the correct output device. This is typically listed as the monitor that is connected to the KVM because the audio is transmitting via the video connections. (Right-click the speaker, open the sound settings, select the correct HDMI output device, and set it as default.)

Refresh Rates/Resolution Issues

Refresh Rate issues | Resolution is incorrect | Bad resolution

• We see refresh rate/resolution issues all the time when using adapters to connect to the KVM. Its important to remember the connection flows FROM the computer TO the KVM. For example if you need to convert a USB C connection, it would be USB C to HDMI Adapter. we are aware that not all adapters work well in a KVM environment.
• A common issue we hear about is monitors not displaying the correct high refresh rate. This can be checked on the manual of your monitor it will demonstrate what refresh rates are supported via HDMI or Display port.
