Unverified曲面屏（1800R/1500R）在32英寸以上超宽屏时能减少眼球转动幅度、降低疲劳，但27英寸及以下平面屏几乎无差异，小尺寸曲面无护眼意义反而影响文字直线显示85% similar Unverified49寸超宽屏应选1800R以内曲率（如1500R/1000R），49寸平面屏两端到眼距离差过大导致边缘变形与偏色，曲面几乎是刚需85% similar Unverified曲率数值越小弯曲越强：1000R曲率贴合人眼视场，适合49寸32:9这类超宽屏减少边缘颈部转动；34寸21:9选1800R或1500R即可，过强曲率在小尺寸上反而导致直线内容（表格、代码）视觉畸变84% similar Unverified27英寸显示器搭配2K（2560×1440）分辨率为护眼与清晰度平衡点，PPI约109，文字锐利无需缩放；27英寸配1080P则PPI仅81，颗粒感明显反而加重视疲劳78% similar Unverified观影舱内置屏幕距离眼睛通常仅40-60cm，屏幕分辨率必须≥2K（2560×1440），1080P在此距离下会明显看到像素颗粒，观感反而不如大尺寸投影76% similar
