Maximize Productivity with 4 Displays

The Nvidia RTX GPU easily drives up to four displays at once: the laptop 1080p LCD and three 4K panels using the mDP, USB-C, and HDMI ports all found on the rear panel.

Open Display Settings

Open Display Settings

System SettingsOpen system settings and then click Displays. The interface will appear as shown if no external displays are attached.

Attach Displays

Attach Displays

The connectors for the displays are all found in the back. Modern displays often support all 3 connector types. You will need a cable for each display you wish to connect. If the display you wish to connect have a matching input type, you can use a cable that converts the signal. We found, for example, that a USB-C-to-DP cable works just as well as a USB-C-to-USB-C cable.

Add Displays

As you add attached the monitor cables the displays will appear on-screen. You can also attach the displays without the settings window open. In this case you will be prompted to configure each display as added. We found that opening the settings window first is easier when adding multiple panels.

Positioning Displays

Once all displays are added you will want to move them to the desired location. We suggest placing the laptop and its panel to one side on a laptop stand (call us for recommendations) and aligning the displays to the bottom edge. Click on Identify to ensure you have them in the proper order. Make sure all the displays are Enabled and the Laptop Screen is selected as the Primary display.

Once you have the panels position you should be able to sweep your cursor across all displays. You may want to increase cursor speed to compensate for your vastly increased realestate. If the cursor does NOT switch smoothly between screens, return to the display settings to adjust as needed.

Scale Displays

Scale Displays

4K displays have a higher pixel density than traditional 1080p or 1440p displays. The solution is to set scaling or change the DPI. We have found that the latter works with the least amount of fuss.

System SettingsRevisit System Settings and then selects Fonts > Fonts. You may then set the DPI as shown - here we use 144 DPI. Then click Start > Leave > Log Out and then sign in again. This will reset all window geometry and result in a more reasonable presentation size for most people.

Change DPI
Detatch Displays

Detatch Displays

System SettingsIt is best to disable displays by visiting System Settings > Displays interface. However, unplugging a display cable will have the same results although not as immediate. In either case, application windows will be moved to remaining visible displays.

Troubleshooting

Q: I would like to run multiple displays with the iGPU. Is this possible?

A: Yes, but it does require additional hardware. We use a universal USB doc to drive two external 4K displays from a single USB-A port. The experience is not as buttery smooth as the Nvidia GPU due to both USB-A bandwidth and iGPU limitations. However, it is useful when you run compute on the Nvidia GPU and use the iGPU for display. See the GPU Select guide to see how to do this.
