螢幕均勻性測試
Pick a color 和 brightness，then 全屏. Good panels show perfectly even color edge-到-edge. Uneven brightness，tinted corners，或 cloudy patches reveal uniformity issues。
Inspect clouding 從 varied angles — IPS glow ramps near corners whereas OLED should stay planar until ABL trims. Prefer dim bias lighting 到 avoid glare washing subtle mura。
Tip：check at 20%，50%，和 80% brightness — uniformity issues often appear only in a specific brightness band. 步驟 2–3 feet back 用於 a less-biased look. Dim your room 用於 clouding tests. In fullscreen，use ↑ / ↓ 到 nudge brightness by 5%。
使用方法
- 從正面與斜角觀察畫面邊緣，IPS glow 會讓周邊亮度差異更明顯。

建議鎖定相機手動曝光，避免手機自動 HDR 誤判或誇大暗角程度。

它補足背光漏光測試：不只看最暗畫面中的角落光暈，也檢查整個畫面的亮度是否均勻。
