The Sony X90L is a great TV overall. Thanks to its high peak brightness, it's great for watching shows or sports in a bright room. It looks fantastic in a dark room for gaming or watching movies in HDR thanks to its high contrast ratio and full array local dimming feature, and it gets bright enough to bring out bright specular highlights in HDR. Thanks to its low input lag and quick response time, it's great for gaming, and it supports advanced gaming features like VRR. It has a narrow viewing angle, so it's not a good choice for a wide seating arrangement.

It remains to add that the Sony X90L offers very good picture quality in both HDR and SDR modes for mid-range 4K QLED TVs. Picture brightness isn’t as bright as mini LED LCD TVs, which usually offer a lot more for LED backlighting and zones.

Sony X90L is fundamentally the same TV as the ones that came before it; same SoC, same video processor, same Android version (10) with Google TV, and still only HDMI 2.1 ports without QMS. The biggest change is that it will later come in a massive 98-inch variant complete with carrying handles!
