Top Deals On Great Products Picked by Techconnect’s Editors See it correspond with your PC’s output ports. While you could use conversion cables, such as DVI-to-HDMI or DisplayPort-to-DVI, they can be a hassle. If you have a VGA port on your PC or your monitor, I suggest staying away from it: VGA is an analog connector, which means your picture will be noticeably less sharp and colors will be less vivid. Step 3: Set up your PC Set up your monitors, plug them in, and turn on your PC. Voila! A perfectly-formed multi-monitor setup! Well, not so fast. Setup is easy, but there are still a couple more steps. The first thing you’ll want to do is configure Windows to play nicely with your multiple monitors. If you’re running Windows 7 or Windows 8, right-click on the desktop and click Screen resolution; in Windows 10, click Display settings. This will take you to a screen where you can configure the options you have for multiple monitors in Windows. Here, you can confirm that all your monitors are detected. Click Identify, which will cause a large number to appear on each of your displays, so you can determine which screen is which. Select the monitor you’d like to serve as your main display (which will also determine where your taskbar and Start button appears). A drop-down menu lets you choose whether to duplicate your desktop or extend your desktop across all the screens. In most multi-monitor setups, you’ll want to extend your desktop across all three (or four, or whatever) of your displays. Alternately, you can set up your multi-monitor configuration in your GPU’s control panel. Right-click your desktop and choose either the Nvidia or AMD control panel (depending on your graphics card), and find the Display section, which will offer similar options as Windows. Gaming It’s one thing to use multiple monitors to do work and watch Netflix. It’s another thing entirely to use multiple monitors to play video games. If you want to use your snazzy new multi-monitor setup to do some three- or four-panel gaming, there are a few extra things you’ll have to take into consideration. Gaming on several displays at once requires far more graphical firepower than gaming on a single screen alone, because the GPU has so many more pixels to push—so if you’re not running a sufficiently robust graphics card or cards, you’ll almost certainly see lag and artifacting in your multi-monitor games. Check out PCWorld’s guide for choosing the best graphics card for gaming. Before you can start playing your games across multiple panels, you’ll need to set up your graphics card and your game. Nvidia users will need to set up Nvidia Surround, while AMD users will need to create an Eyefinity group for their monitors. You’ll also need to go into your game—not all games are multi-monitor compatible—and configure the video or display settings to the correct resolution so that the game spans across all of your monitors instead of staying squished on just one. You’ll also want to play around with other settings as the game allows, including field of view (too low, and there will be too much going on around you; too high and everything on your left and right screens will be hugely distorted). For gaming, it’s easier if you have multiple identical displays, because otherwise you’ll run into issues with resolution, distortion (if your displays aren’t at the same height), and color calibration, all of which can be difficult to work with if you’re trying to play in a “seamless” environment.
