Contrast Ratio & Uniformity:
With the display now showing “perfect” color and brightness, we continue on to take our contrast readings. We used our luminance meter for our traditional contrast readings as indicated below.
Black Spot |
White Spot |
Contrast Ratio |
0.25 | 221.6 | 886.4 |
I realize that the maximum luminance could have been a bit higher, but when we test LCDs we make sure that they are calibrated properly and then give you the results that you will see when using them - not the maximum "theoretical" numbers. After we finished with our luminance meter, we also used the Datacolor Spyder with the latest software update to perform contrast readings as various brightness levels.
We used the updated Spyder software to get a lighting uniformity reading at different brightness levels. The software and hardware combination takes readings at different brightness levels at different places on the screen to blend together results. It's interesting to see how different brightness levels on the monitor yield much different uniformity results. Please note the uniformity and brightness levels below.
