display resolution

[Tony Zuccolotto]

Dr. Klatsky,

You can set the display resolution by double-clicking on the Experiment
object (at the top of the Structure View) and then clicking on the
Devices tab, and then choosing the Display object properties.   You can
set runtime display resolution and color depth.

Some additional advice...
If you are loading bitmaps and need fast performance make sure your
bitmaps are only as large as you really need them, e.g. you can run the
experiment in 1024x768 to get a crisp resolution, but if the stimulus
image is only in the center 25% of the screen you should clip the
picture down to that size.   Likewise you can look into reducing the
Frame size of the ImageDisplay object and/or try changing BackStyle
property to "transparent" (to prevent an initial clear operation being
performed within the display), e.g. if one bitmap completely overwrites
the previous, then you can improve the throughput of the presentation
sequence by using "transparent" vs "opaque".

Hope that helps.

How do you set the display resolution for all trials of an experiment.
We
are displaying .bmp files and want to change the default resolution that
eprime uses

Thanks
