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. This is an issue with all KVM switches that have hotkey and mouse gesture switching. We recommend using the USB 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.

We are working on solutions but do not have a timeline at this time. We recommend trying an application called 3RVX for Windows-based machines. This software allows the user to program hotkeys such as play/pause, volume, etc... and will remain active while using applications and playing games on your PC.

Please email us at service@tesmart.com and describe your computer environment. If we are unable to resolve the issue, we can provide a new device to confirm the problems are specific to that unit or initiate a hassle-free return.

Due to robust demand, we typically ship the products airfreight. This has caused issues with hazardous goods regulations. The remote requires a CR2025 battery, which can be found at most convenience and grocery stores.

Using the hotkey command: Scroll Lock, Scroll Lock, F11.

Most models have the ability to reassign Scroll Lock to Right-CTRL. Please refer to the manuals for the hotkey instructions or email us at service@tesmart.com for assistance.

Absolutely. Each port is equipped with EDID. The switch will adjust the resolution for each port based on the capabilities of the input device and monitor. If Port 1 has a computer that can only provide 1920x1080, you can also have a computer in Port 2 at 3840x2160. The switch will send the appropriate resolution to the monitor. Likewise, if one computer requires an adapter such as VGA to HDMI, you can continue to use a normal HDMI cable on the other ports. Please note that your monitor will need to accept 3840x2160 to achieve that resolution.

We have tested several Mac computers (2018 Macbook Pro, 2012 Mac Mini, 2008 MacPro) and have not had issues. That said, recent versions of MacOS (since High Sierra and Mojave) limit the refresh rate of external monitors to 30 hz. The resolution limitation is not an issue with the KVM but a software limitation of Apple's operating system. There are several workarounds posted on the internet.

A cable that is 30 ft or less can transmit High Def quality at 60Hz.
A cable that is 15 ft or less can transmit Ultra HD quality at 30Hz.
A cable that is 10 ft or less can transmit Ultra HD quality at 60Hz.

Occasionally the mouse movement for Mac operating systems may jump. Please try using the USB2.0 port for your mouse input. If problems continue, please confirm the mouse works correctly when plugged directly into the PC that exhibits the issue.

Unfortunately, not all multimedia functions are passed through the KVM to the input PC. We recommend trying the USB2.0 port but we cannot guarantee all multimedia functions.
List of Hotkey Functionality:
  Scroll Lock, Scroll Lock, Page Up = switch to previous port
  Scroll Lock, Scroll Lock, Page Down = switch to next port
  Scroll Lock, Scroll Lock, 1 - X = switch to desired port (X is the number of ports for your unit)
  Scroll Lock, Scroll Lock, Space Bar = switch to next port turn on autoscanning
  Scroll Lock, Scroll Lock, + / - = increase/decrease autoscanning time interval
  Scroll Lock, Scroll Lock, F11 = enable/disable unit's beep sound
  Scroll Lock, Scroll Lock, F12 = enable/disable mouse gestures

On occasion TV's will exhibit "overscaling" issues. This is due to the input device, typically a PC, having a slightly different resolution than a television. There are a number of ways to correct the issue by making adjustments to Windows and Mac operating systems.

A KVM (keyboard, video, mouse) switch is a hardware device that allows a user to control multiple computers from a single keyboard, video monitor, and mouse. Previously KVM's were mostly seen in data centers but in recent years have expanded to the consumer market due to the number of video devices that many homeowners use (computers, streaming devices, game consoles, security systems, etc.)

A KVM is different from an HDMI switch by adding the keyboard and mouse functionality. HDMI switches are very inexpensive because they are very limited in functionality. If a computer is one of the many inputs that need to be managed, a KVM will be the preferred device.

Anyone that needs to manage more HDMI inputs than what their TV or computer monitor allows will benefit from a KVM. Also, users of multiple PC's have a need for a KVM switch as it eliminates the need to have multiple peripherals and monitors.

Yes. A wireless mouse/keyboard with 2.4G receiver is allowed. If you have issues with functionality, please try the USB2.0 port. Please note that using the USB hub will disallow keyboard hotkeys for switching.
