Frequently Asked Questions
Can I use a KVM switch for 4 computers with a Mac?
Most modern KVM switches support macOS since they act as standard input devices. Just ensure the video output from your Mac matches the ports on the switch like HDMI.
Do I need to install drivers?
No drivers are typically required as these switches use standard protocols. They are plug-and-play devices that work with most operating systems instantly.
Why is my screen flickering when I switch?
Flickering often happens if the EDID signal is unstable. Try checking cable connections or look for a model with EDID emulation to fix this issue.
Can I connect more than four computers?
No this category is specifically designed for four computers. If you need more you would need to look at higher port counts or a daisy chain setup.
Do I need a power supply?
Yes most four port switches require an external power supply to function correctly. This ensures stable video output and USB data transfer speeds.
What is the difference between copy and extend mode?
Copy mode shows the same image on all monitors while extend mode spreads your desktop across screens. Not all switches support extend mode for multiple outputs.
Can I use this with gaming consoles?
Many HDMI switches work with gaming consoles as long as the resolution matches. Check the manual to confirm compatibility with your specific console.
How long is the USB cable included?
