Why Uniformity Matters
For Photographers
Uniformity is critical for editing. If your screen has <strong>vignetting</strong> (dark corners), you might over-brighten the edges of your photos, ruining the print. Use this test to verify that your monitor displays brightness evenly across the entire frame.
For Gamers
The <strong>"Dirty Screen Effect" (DSE)</strong> is visible when the camera pans across a uniform color (like a sky or football field). It looks like faint vertical bands or clouds. This test helps you check for DSE and clouding on new gaming monitors within the return window.
Common Uniformity Defects
1. Backlight Bleed
光线从屏幕边缘漏出，破坏了黑暗环境下的黑色表现。
2. Clouding (Mura)
由于组装不当或压力导致的亮度不均匀斑块。
3. Color Tinting
面板各处出现偏暖或偏冷的色彩偏移，使得色彩校准无法进行。
