Color and Brightness Screen Uniformity
Panel color uniformity
The thesis behind screen uniformity is how the image is distributed across the screen. A uniform screen displays an image which remains consistent in terms of clarity, color, and brightness at all points across the display area. We test at 50% and 67% brightness levels.
The screen color uniformity (the same colors measured at nine different parts of the screen). This is a very good result.
Panel Luminance uniformity
A screen can be a non-uniform screen. On an all-white background, such a screen has a somewhat dirty appearance, with things like banding visible. However, as bad as this sounds it may not noticeably affect the image when looking at colored content like your desktop and/or gaming.
Panel luminance or brightness uniformity tells us how well the screen is lit up by the LEDs and where it is brighter compared to other spots. We measure at nine hotspots on the screen, with slightly varying results really. Things are very even, despite what you might think when you look at the percentage values. For any result in this chapter, a value of under 20% is noticeable to e untrained eye. The panel, however, shows a pretty large offset at the upper left quadrant resulting in an average score at best.
