What reviewers say

PC Gamer and Tom's Guide praise the sharp 4K picture, smooth motion and automatic PS5 picture features, but criticise the weak speakers. TechSpot finds full-array local dimming improves HDR over edge-lit monitors, while noting blooming from its 96 zones and the absence of an sRGB mode. All three find stand adjustment limited. PC Gamer also reports that application-specific picture profiles did not always switch reliably in its review.
