Product Information
Full details
The ATEN CS784H is a 4-port desktop KVMP switch designed for professionals and power users who need to control multiple computers using a single keyboard, mouse, and 4K display. It provides a significant boost to desktop efficiency by eliminating peripheral clutter and enabling instant switching between four systems. A key caveat to consider is that while it supports USB 2.0 peripheral sharing, users requiring high-speed data transfer (USB 3.0 or higher) may find the peripheral ports limited by the 2.0 interface speed.

FAQs
Does this switch support audio?

Can I use a wireless keyboard and mouse?

What is the maximum resolution supported?
The switch supports up to 4096 x 2160 pixels (4K DCI) at 60Hz.
Does the switch require software installation?
No, it is a hardware-based solution and works plug-and-play across all major operating systems.
Can I use the USB ports for high-speed external hard drives?
The USB ports are USB 2.0, so while they support external drives, data transfer speeds will be limited to 480 Mbps.
Are all cables included in the box?
Yes, the package includes 4 HDMI cables, 2 USB 2.0 cables, a remote port selector, and the power adapter.
Troubleshooting
Monitor does not display an image after switching
Check all HDMI connections and ensure the target computer is powered on. Try toggling the switch again or power-cycling the KVM unit.
Keyboard or mouse is not responding
Verify the USB A-to-B cable connection to the host computer. Ensure that your peripheral is not a specialized device requiring proprietary drivers that may conflict with KVM emulation.
Screen resolution is incorrect
The switch uses Video DynaSync to maintain display settings. If the resolution is wrong, ensure the monitor is powered on before the KVM switch, then re-select the port to allow the unit to re-detect the display.

Setup, Compatibility & Care
To set up the CS784H, connect your monitor, keyboard, and mouse to the console ports on the back of the switch. Use the provided HDMI and USB 2.0 A-to-B cables to link each of the four computer ports to your machines. Once connected, plug in the provided DC power adapter. The switch supports hot-plugging, meaning you can connect or disconnect computers while the devices are powered on. For care, ensure the unit is kept in a well-ventilated area within the recommended 0-40 °C temperature range. Keep the ports free of dust and debris, and avoid using excessively long cables, as these can degrade signal quality at 4K resolutions.
