Gaming across two monitors is a dream for many PC enthusiasts. You get to keep your game on one screen while watching a walkthrough, streaming your session, or chatting with teammates on the other. But managing two separate keyboards and mice for each system — or constantly unplugging and replugging peripherals — turns that dream into a cable management nightmare. In this step-by-step guide, we’ll show you how to set up a dual-monitor gaming rig with just one keyboard and mouse, so you can stay in the action without the clutter.

Why You Need a Unified Input Setup for Dual Monitors

Dual-monitor gaming setups are increasingly popular among competitive players and content creators. A single keyboard and mouse setup not only saves desk space but also reduces input lag and clutter. Whether you’re running two gaming PCs, a PC and a console, or a laptop alongside your main rig, sharing one keyboard and mouse between screens lets you switch instantly without breaking your flow. For example, you might be fragging on your primary monitor while keeping a browser or chat app open on the secondary screen — all controlled from your main gaming peripherals.

Hardware Options for Peripheral Sharing

There are two primary ways to achieve a one-keyboard-mouse dual-monitor setup: using a KVM switch or using software-based solutions. Each has its pros and cons, depending on your gear and gaming needs.

1. KVM Switches: The Hardware Route

A KVM (Keyboard, Video, Mouse) switch lets you connect multiple computers to a single set of peripherals. For gaming, look for a KVM that supports high refresh rates (144Hz or above) and low latency. Many modern KVMs also pass through USB 3.0 ports, so you can connect your headset and controller too. This is ideal if you have two separate gaming PCs — for instance, one for competitive shooters and another for strategy games. A KVM switch eliminates the need to swap cables manually and keeps your desk tidy.

2. Software Solutions: The Flexible Option

If you’re running one PC with two monitors, software like Microsoft PowerToys (Mouse Without Borders) or Synergy can let you share a keyboard and mouse across multiple computers on the same network. For a single PC, Windows’ built-in multi-display settings already allow seamless cursor movement between screens. However, for gaming, you’ll want to ensure your input devices are connected directly to the gaming system to avoid added latency. Pairing a high-performance Rival 5 gaming mouse with a responsive mechanical keyboard ensures you never miss a click during intense matches.

Step-by-Step Setup Guide

Step 1: Choose Your Primary Gaming Peripherals

Start with peripherals that are built for speed and endurance. A wired or low-latency wireless mouse with a great sensor is essential. The Rival 5, for instance, offers a lightweight design and customizable RGB zones, making it perfect for switching between gaming and productivity. Pair it with a durable keyboard that has programmable keys — like the Apex Pro series — so you can assign shortcuts for monitor switching or volume control.

Step 2: Connect Your Displays

Connect both monitors to your graphics card using DisplayPort or HDMI cables. Ensure your GPU supports multiple outputs. Once connected, right-click your desktop and go to Display Settings in Windows. Arrange the monitors to match your physical setup. Set your primary monitor (where your game will run) as the main display. For a KVM-based setup, connect each monitor to the KVM’s video inputs, then run a single cable to your GPU.

Step 3: Configure Input Sharing

• Single PC dual monitors: No extra hardware needed. Your keyboard and mouse will automatically move across both screens. Just open Settings > System > Display and drag the monitors to their physical positions.
• Two PCs with a KVM: Connect your keyboard and mouse to the KVM’s USB ports, then connect each PC to the KVM’s USB and video inputs. Press the KVM’s switch button (or use a hotkey) to toggle between computers. Some KVMs even support audio switching, so you can use your gaming headset on either system.
• Two PCs with software: Install a sharing tool like Mouse Without Borders on both computers. Make sure they are on the same network. The software will create a virtual KVM, allowing you to drag your mouse from one screen to the other. Note: This may introduce slight input lag, so it’s best for non-competitive tasks like browsing or streaming overlays.

Step 4: Optimize Cable Management

With two monitors and peripherals, cables can quickly become a mess. Use velcro ties or cable sleeves to bundle monitor cables together. Route them behind your desk or use a cable tray. For a cleaner look, consider a wireless keyboard and mouse — but ensure they have a low-latency connection mode (like 2.4GHz or Bluetooth 5.0). The Arctis Nova 4P Wireless headset, for example, uses a USB-C dongle for lag-free audio, so you can keep your desk free of extra wires while enjoying immersive sound on either monitor.

Software Tweaks for a Seamless Experience

Once your hardware is connected, fine-tune a few settings:

• Cursor lock: In many games, you can set the cursor to stay on the primary monitor to avoid accidentally clicking on the secondary screen. Look for “fullscreen” or “borderless windowed” mode in game settings.
• DPI scaling: If your secondary monitor has a different resolution, adjust DPI scaling in Windows so your mouse feels consistent across both screens.
• Hotkeys for quick switching: Assign a keyboard shortcut to toggle between displays or mute your secondary monitor’s audio. A programmable keyboard like the Apex Pro series lets you create macros for these tasks.

Common Issues and How to Fix Them

Issue	Solution
Mouse cursor moves slowly between monitors	Check DPI settings; ensure both monitors are running at the same refresh rate if possible.
Keyboard input lags on the secondary PC	Use a wired connection or a KVM with low-latency USB pass-through.
Game minimizes when clicking on the second screen	Switch to “borderless windowed” mode in the game’s video settings.
Audio comes from the wrong monitor	Set your headset as the default playback device in Windows Sound settings.

Choosing the Right Peripherals for Your Dual-Monitor Setup

Not all keyboards and mice are created equal for multi-monitor gaming. Look for:

• Low latency wireless: A wireless mouse with a dedicated dongle (like the Rival 5’s 2.4GHz mode) ensures zero lag.
• Programmable keys: Map functions like “switch monitor” or “mute second screen” to dedicated buttons.
• Comfortable design: Long gaming sessions demand ergonomics — choose peripherals that fit your hand size and grip style.
• Wide compatibility: Some KVMs work best with certain brands. Check compatibility with your mouse and keyboard before purchasing.

Conclusion: Streamline Your Dual-Monitor Gaming Rig

Setting up dual-monitor gaming with one keyboard and mouse is easier than ever. Whether you opt for a hardware KVM or a software solution, the key is choosing peripherals that are responsive, comfortable, and versatile. By following the steps above, you can enjoy the best of both worlds — immersive gaming on your primary display and seamless multitasking on the secondary — without the clutter of extra cables or input devices.
