The Sony X900H, also sold as the X90CH at Costco, is a great 4k TV for nearly any type of content. It has a VA panel with an excellent contrast ratio and a full-array local dimming feature that makes blacks look even better in the dark. It’s well-suited for bright rooms, as it has decent reflection handling and gets bright enough to easily overcome glare. It displays fast-moving scenes with minimal blur thanks to its quick response time and optional Black Frame Insertion feature. Gamers should be happy with its low input lag, which remains low even when playing in 4k with 10-bit HDR. Unfortunately, the advertised variable refresh rate (VRR) support is not yet functional. Also, its viewing angles are quite narrow, so images look washed out when viewed from the side.
The Sony X900H is a great TV for mixed usage. Its picture quality is great thanks to its excellent contrast ratio, high peak brightness, and wide color gamut. HDR content also looks good, with rich colors and highlights that pop for the most part. Gamers should appreciate its fast response time and low input lag, although VRR support is currently missing. Unfortunately, it’s less suited to watching with larger groups because it has narrow viewing angles that make the image look washed out from the side.
