Thanks. I'm looking at 2 gigs of memory for each laptop. I'm loading
multiple images per slide, too. But I can load the background first,
pause, then load the actual stimulus. This should help me control
refresh time, but how do I measure it to be sure?<br>

<pre wrap="">for what it's worth, i verified stimulus/screen timing on some HP
Pavillion notebook computers with a photodiode and there were no
problems whatsover. it very pleasantly surprised me. i used
cumulative timing, disabled the sync to vertical onsets and offsets,
and then pushed the limits down to stimuli of ~50 msec (3 frame)
duration.
the only time timing was ever an issue was when i was reading in
multiple image files per slide object. i was able to remove this
problem by (a) reading the stimuli into a buffer before calling them
in the eprime procedure and (b) without pre-loading the images, using
a pavillion with more memory (1 GB) and a better video card.
cheers,

<pre wrap="">Dear Leisha,
If I remember correctly, there were some issues with refresh rates of laptops so
that timing may not be as accurate as you want. This may be neglibile for
decision research. You may want to have a regular CRT to plug into. I think
some of this is addressed in the list serve archive.
best,
Mike

<pre wrap="">I'm pricing out laptops to run a simple eprime task at various
locations. Do any of you have recommendations for laptops that work well
for this? So far the HP Pavilions and Dell Latitude or Inspiron are
looking good. I'm steering clear of Celeron processors and I don't think
I can use MacIntosh, right?
Any problems to report? Any praise for specific laptops?
