2. Stability

   1. Luminance

      1. Warm-up

      2. Screen surface luminance homogeneity
         
         Sample CRT Spot Luminance Measures

      3. CRT bandwidth limits or do horizontal objects have the same contrast and luminance as vertical objects
              
         
         
         
         Vertical grating luminance divided by horizontal grating luminance on several identical CRTs and one LCD.
         
         Effect of line width on bandwidth limitation.

      4. Lighting (contrast)
          

         Dark	Room Light	Direct Sun Illumination

   2. Chromatic

      1. Warm-up

      2. Monitor variation

      Neuro Lab CRT	Laptop LCD
      Desktop LCD from Side	Desktop LCD straight on
      Cog/Stat Lab LCD (same type as desktop)
