III. Devices: B: Stability

  1. 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
