Meridian 3 75
4. Visual Characteristics
4.1 Test conditions
Unless otherwise specified, this specification is defined under the following conditions.
1) Input signal: As defined in 3.3,
1920 x 1080 non-interlaced mode (1920 x 1080 @60Hz)
, signal sources
must have 75 ohm output impedance.
2) Luminance setting: controls to be set to
250
nits with full screen 100 % duty cycle white signal
3) Warm up: more than 30 minutes after power on with signal supplied.
4) Ambient light: 400 -- 600 lux.
5) Ambient temperature: 20 ± 5
°
C
4.2 Brightness/ Brightness Uniformity
Follow Panel specification.
4.3 Color Temperature Adjustment
There are three factory preset white color 9300K, 6500K, sRGB.
Apply full gray 64 pattern, with brightness in 100 % position and the contrast control at 50 % position.
The 1931 CIE Chromaticity (color triangle) diagram (x, y) coordinate for the screen center should be:
