The Sony X90J offers nearly everything we’d want from a mid-range 4K LED-LCD TV. For the money, there are few LED-LCD TVs that can match it in terms of picture quality and feature set, making it top of its class for mid-range models. We don’t love that the TV only has two HDMI ports with 4K/120Hz support, and it has some issues with screen glare, but largely this is a fantastic TV that most folks will absolutely love.
Best-in-class image quality; Excellent upscaling; Cognitive Processor XR; Easy setup and Google TV;
Lingering HDMI issues; Slight screen glare; Mediocre off-axis viewing; Outclassed by X95J
