Second, I measure a series of grey patches: The black level above is moderately high, the white level is very high and the white point is far from the daylight locus ( DE > 2). White Correlated Daylight Temperature = 7604 K, DE 2K to locus = 11 Native response (optional)įirst, I checked the basic display response: When new, uniformity measurements for the Aspire 5742 were very good. Moderate variation in white level and colour temperature measurements above could be due to age. However, it took 30 minutes for colour temperature to stabilise.Īspire 5742 Correlated Daylight Temperature (K) uniformity.

It complements a previous post about calibrating a NEC P221W display. This post describes calibration for an Acer Aspire 5742 laptop with WLED (White LED backlight) display. The native display response is generally awful and can be improved by calibration. Most laptop computers are designed to a price-point and have cheap LCD displays.
