What this KVM switch does
The IOGEAR KeyMander Nexus GCS1337 is a 3-port gaming KVM switch that lets you share one monitor, keyboard, mouse and headset between a PC and multiple game consoles. It supports 3840 x 2160 resolution at 60 Hz via HDMI 2.1 and also handles 1440p at 144 Hz. The unit includes a built-in gaming DAC for enhanced audio and Bluetooth connectivity for on-the-fly adjustments via a smartphone app.
Check your current connections
Before ordering, verify that your monitor has an HDMI 2.1 input to use the 4K 60 Hz or 1440p 144 Hz video modes. You will need free USB-A ports on your PC for the keyboard, mouse and two additional USB-A connections, plus one USB 3.0/3.1/3.2 Gen 1 port. A 3.5 mm audio jack is required for headset passthrough. Ensure your consoles are among the supported Xbox Series X|S, Xbox One, PS4 or Nintendo Switch systems.
What it replaces and when to upgrade
This switch replaces separate monitor inputs, multiple keyboard and mouse sets and individual headset connections for each platform. The jump is worth it if you regularly move between a PC and supported consoles and want a single desk setup with keyboard-and-mouse control on console titles. It is not for setups that require more than three total video sources or for consoles outside the supported Xbox, PlayStation 4 and Nintendo Switch families.

Questions about this item
Does the KeyMander Nexus GCS1337 include the cables needed to connect my PC and consoles, or must I buy them separately?
The package provides the KVM unit; you supply the DisplayPort or HDMI 2.1 video cables and USB-A leads for keyboard, mouse and headset.
Should I choose this 3-port model over a smaller KVM if I want 1440p at 144 Hz on my gaming monitor?
This switch delivers 3840 x 2160 at 60 Hz and 1440p at 144 Hz across its three ports, so the extra ports do not limit the high-refresh mode.
When I plug my Xbox Series X and PS4 into the GCS1337, will keyboard and mouse input feel like native controller response?
The built-in gaming DAC and DynaSync keep latency low, letting you map keys and adjust sensitivity via the mobile app for near-native feel.
