Frequently Asked Questions
Do I need a special cable for 4K monitors?
Yes, to get the most out of your 4K display, especially if you want high refresh rates (120Hz or 144Hz) or HDR, you should use an HDMI 2.1 or DisplayPort 1.4 cable. Older HDMI 2.0 cables may struggle with high-bandwidth 4K signals.

It depends on the specific KVM switch. Some are designed specifically for dual-monitor setups, while others, like the OnBuy.com 3-monitor model, are built to handle even more complex arrays. Always check the maximum resolution and monitor count supported by the switch before purchasing.
