Although the option is available, we do not typically recommend using "Match Desktop Resolution" for the DisplayDevice. Setting a specific resolution in the DisplayDevice's Property Pages is encouraged to limit variability if testing on multiple machines. If "Match Desktop Resolution" is set to "Yes", an experiment can display differently on machines with varying resolutions.
By default, the value for this setting is "No" (which does not match the resolution). However, there is one scenario where matching the desktop resolution is the recommended option. This option is preferred when you have multiple DisplayDevices in your experiment. Setting this option to "Yes" when using multiple displays improves E-Prime's ability to accurately determine all display settings.
NOTE: As mentioned above, "Match Desktop Resolution" is recommended sparingly. Just because a machine can run at 1080p or 4K, doesn't mean it should be run at those resolutions. Accurate timing may be more difficult to achieve with higher resolutions.
I like "Match Desktop Resolution" a lot, but only during program development, and only when development does not itself depend on particular display settings. I just find it tedious to sit through display resets every single time I do a test run, and I do a *lot* of test runs during development (almost every time I make a change in a program). Happily, "Match Desktop Resolution" spares me that trouble. But before using it to run subjects, I advise my users to set desktop resolution to their desired setting so that E-Prime can enforce that on all their subject-running stations.
