Overview
This page provides a conceptual introduction to the “Environment” in LabMaestro (in the Project panel), where all connected displays and VPixx devices are listed.
After reading this guide, you will have an understanding of the differences between Displays and Devices in LabMaestro, how to add them to a LabMaestro project, and how to configure various hardware settings for use, either within or outside of LabMaestro projects.
VPixx Devices
In LabMaestro, “Devices” refers to any VPixx hardware connected to the computer via USB. This includes our VIEWPixx line of research-grade monitors, the PROPixx projector, or our DATAPixx3 video I/O hub and data acquisition system. One exception to this rule is our TRACKPixx3 eye tracker, which is not directly connected to the computer but is detected and accessed via its connection to the DATAPixx3. All VPixx devices have a “Device Settings” menu, which allows you to configure various features and settings. You can access the device settings by double-clicking a VPixx device, which opens the “Device Settings” menu for that device.
Single-clicking a VPixx device opens a Properties panel for that device on the right-hand side of the window. The Properties panel gives information about the device.
The following table summarizes the different pieces of information available for VPixx devices in the Properties panel:
|

By right-clicking on a VPixx device, you will see several options available:
The following table describes each of the options:
|
Option |
Description |
|---|---|
|

|
Digital I/O Tester |
Open the Digital I/O tester, which allows you to read the Digital Inputs and set the states of the Digital Outputs for testing purposes. |
Displays
In LabMaestro, “Displays” refers to the type of display (e.g., monitor or projector) connected to your computer/graphics card via a video cable; this includes third-party displays as well as VPixx displays.
You can add a display to your LabMaestro project by right-clicking on the display, listed under “Environment”, and selecting “Add to project”. Doing so will automatically open a window with display settings and options; this window can also be accessed by double-clicking the display listed under “Environment”. In this window, the user can enter the viewing distance (in cm) or the resolution (in Pixels Per Inch) of the monitor to automatically convert dimensions from pixels to cm or degrees in the LabMaestro project (if the user chooses to display dimensions in these units).
The user will also be able to gamma-correct the display for use in the LabMaestro project if they have a VPixx edition of the X-Rite i1Display Pro colorimeter or the X-Rite i1 Pro spectrophotometer.
Single-clicking a display opens a Properties panel for that display on the right-hand side of the window. The Properties panel gives information about the display.
