Display Resolutions for Looking Glass Devices

In Desktop Mode your Looking Glass system will show up as an additional monitor. You'll need to open Display Settings in Windows, or System Preferences -> Displays in MacOS and ensure your Looking Glass is set to Extended Display Mode, and that display scaling is set to 100%. If this is not set then software designed for Looking Glass systems will not work properly. See the table below for your device's display resolution.

When the above button is pressed, the Looking Glass should show a 3D image like below. To close this image, move your mouse over and click anywhere on the image. The image should appear 3D. If it appears with diagonal lines (as on the right), there is an error. Please retry the setup steps above to ensure it is properly configured. If that doesn't fix it, try troubleshooting. Once the setup is complete, go back to the [User Guide welcome page to begin working with the Looking Glass.
