This is a plea for other vision scientists to start sharing their successes and failures with modern displays and video cards.
The days of CRTs are coming to a close (even quality used ones are hard to find). Modern display devices tend to do a lot more fancy processing under the hood, making it a real challenge to use them for vision science. Our lab recently purchased a high-end projector, only to find out that it has serious issues, which, at the very best, will be mitigated by a lot of extra programming, and at worst, will make it useless. No magazine or website intended for the general public is going to publish the kind of measurements that would allow us to select good equipment for vision science. Instead, we need to share our own findings. The PTB wiki seems like a good place for this, given the difficulty people have had searching the Yahoo form.
There are two relevant pages at the moment, and hopefully more to come:
http://psychtoolbox.org/wikka.php?wakka=DisplayDevices
http://psychtoolbox.org/wikka.php?wakka=FAQ10BitFrameBufferResolution
Even a single paragraph about a device can be helpful. I suggest tagging your entries with your name so that other folks with the same hardware can contact you if their experience differs, though this is certainly optional.
