| What screen resolutions are possible at BIAC3 and BIAC5 (monitors not goggles)? When I used BIAC3 in the past, the only resolution that reliably displayed images was 800 X 600. Is this still the case? |

I'm not aware of any specific resolution limitations when using the projector. On all of our other BIAC computers you can set the resolution in the typical manner (right click on the desktop, properties, settings). There might be issues with sizing if you go too small. But you can schedule a user test to verify those details.
Like you mention though, with the goggles, you can only use 800x600. |

The projectors will work at pretty much any screen resolution.
The monitors themselves, the ones you sit at, do not support all video modes, however. You should use the test option when you try changing screen settings, where it reverts back within 15 secs if you don't like it. If you accidentally select a resolution that is too high or too wide for the monitor you will lose the image and it is a pain to get it back. (You have to use a different monitor to get access to the image again). We will probably upgrade those monitors soon to avoid this problem.

| Thanks for these great answers. It seems the problem I was having was due to the monitors themselves (described by Jim Voyvodic below). I'll plan to set up a user test and use the test option as suggested when changing resolutions. In the meantime, is it known what the limits are (ie what is too high or too wide)? How soon do you think the monitors will be upgraded? Thanks again. |

Betsy,
Those monitors should work just fine with 1024 x 768 resolution. Make sure you leave the refresh rate at 60 Hz. What resolution are you trying to display?

Thanks Francis. 1024 x 768 should be fine, actually. I tried it at a higher resolution once for no good reason and had the problem Jim described with losing the image. I'll stick to 1024 x 768 in the future.
All the best,
Betsy |

Hi Betsy,
Did you change the screen resolution at BIAC5? We run experiments with e-prime, and recently noticed that our task time is slightly off (as of March 22nd). I also noticed today that the screen resolution was much higher (I'm guessing that before it was 800 X 600 and now it appears to be 1024 X 768. As a result of this, e-prime's screen refresh rate has changed from 59/60 to 75, which we believe is responsible for the errored task. I've checked all of the output .edat files, and it is the case that the rate changed from 59/60 up to 75 between the 22nd and the 25th of March. Would you mind if we changed the resolution back to the original one? I know at least one other lab uses e-prime... they should probably be alerted about this.
Thanks,
Vanessa |

Hi Vanessa,
It wasn't me. I haven't been running any experiments at the scanner since Dec. when I was using 800 X 600. I was just planning for future experiments in this post.
Sorry you were having trouble though!
Just one extra piece of info -- the screen resolution is periodically changed by various users. It'd probably be best to check each time you scan (Susan suggested this to me last year).
All the best,
Betsy

Thanks Betsy! That's a good standard to have, and it's a pretty quick fix. I'll do some tweaking at our next scan and get the message out to my lab!
Best,

Hi,
I would definitely advocate checking the display settings before each session. We have had instances when a user's settings (i.e., extended desktop) remain for the next user. There is no one display setting that all folks use, so likely this will come up at some point for everyone.
Thanks!
