How to Setup and Use Dual Monitors for Gaming PC

Using two monitors for your gaming PC can greatly improve your experience. A dual monitor setup allows you to multitask more efficiently, gives you more on-screen real estate for your games, and lets you keep an eye on chat windows, streams, tutorials, and more while you play.

Setting up a dual monitor system is easy if you follow these steps:

Choose Your Monitors

When selecting monitors for a dual setup, there are a few things to consider:

  • Size – 24-27 inches is ideal for most dual monitor gaming setups. Ensure your desk has enough space for two monitors of the size you choose.
  • Resolution – 1080p or 1440p. Higher resolutions like 4K are not necessary for secondary monitors.
  • Refresh Rate – Aim for at least 75Hz refresh rate on the primary gaming monitor. Refresh rate on the secondary monitor is less important.
  • Features – G-Sync and FreeSync are useful for eliminating screen tearing on your main display. IPS panels offer better viewing angles.

Ideally, your primary gaming monitor should have higher resolution, refresh rate and features than the secondary display.

Set Up Your Hardware

  • Graphics Card – You’ll need a GPU that supports dual monitors like an NVIDIA GTX 900 series or AMD RX 400 series card or better. Many integrated graphics chips also work.
  • Video Ports – Use DisplayPort and/or HDMI ports to connect both monitors. Avoid using VGA.
  • Stands/Mounts – Set up both monitors side-by-side. Monitor arms/wall mounts can save desk space.
  • Cables – Use high quality DisplayPort or HDMI cables to connect each monitor.

Configure Display Settings

Once your hardware is connected:

  • In Windows Settings, click System > Display. Ensure your monitors are detected.
  • Arrange your monitors logically – place your main display on the right or left in Display settings.
  • Set the refresh rate to the highest possible on your main display. 60Hz is fine for the secondary display.
  • Enable G-Sync/FreeSync if supported on the main gaming monitor.
  • Set scaling for text/apps to 100% to avoid blurriness.

Optimize Windows 10 for Dual Monitors

To make the most of your dual monitor gaming setup in Windows 10:

  • Set different solid background colors on each display under Personalization settings so you can quickly distinguish them.
  • In Taskbar settings, enable “Show taskbar on all displays” to access the taskbar from both monitors.
  • Use the Windows Key + P keyboard shortcut to quickly change display configuration without going into settings.
  • Set system sounds like notifications to only play on your main display under Sound Settings > App volume and device preferences.

Get the Best Dual Monitor Gaming Experience

With your dual monitors set up, a few tweaks will enhance your gaming experience:

  • Run games in full screen mode on your main display for maximum performance.
  • Use your secondary display for Discord, chat windows, streams, music players and hardware monitoring software like MSI Afterburner.
  • Refer to maps, tutorials or guides on the second monitor if playing complex games.
  • Stream or record your gameplay on one monitor while playing the game on the other.
  • Temporarily disable the second monitor for competitive/high action games where maximum FPS is desired.

Troubleshooting Tips

If you encounter issues like flickering, no signal, or cursor boundary problems with your dual monitors:

  • Check that monitor cables are properly inserted and secured
  • Update your graphics card drivers
  • Disable G-Sync/FreeSync if flickering occurs
  • Adjust refresh rate to slightly lower values
  • Set primary monitor as default in Windows Settings > System > Display
