== Interesting Technical Documentation on the Web ==

**Graphics card technology:**

[[http://pymolwiki.org/index.php/Stereo_3D_Display_Options PyMol-Wiki page on different options and setup tips for 3D display hardware - Also applies to Psychtoolbox]]

** Databases listing properties and support for different ""OpenGL"" extensions on different graphics hardware **

[[http://homepage.mac.com/arekkusu/bugs/GLInfo.html GLInfo - Support on Mac OS/X, sorted by OS release, PowerPC vs. IntelMac and model]]
[[http://www.wikipedia.org Wikipedia has nicely written overview articles about different graphics cards and how they differ]]

** Hardware tests (graphics and other) and technical articles about hardware **

[[http://www.ati.com/technology/avivo/pdf/Avivo_Display_Engine_Whitepaper_v2_final.pdf ATI-Whitepaper: The AVIVO display engine of ATI Radeon X1000, FireGL V7300 and later models]]
This whitepaper from ATI covers the video output capabilities of their current graphics cards. It explains their 10 bit framebuffers and DACs, gamma- and color-correction, video scalers and support for different display devices. This is not supported on Mac OS/X 10.4 Tiger. Tests on MS-Windows are pending.

**Display technology:**

Interesting articles about modern flat panel technology - and probably a good explanation why you should not use them for well controlled stimulus presentation, especially not for motion stimuli.
