Both the Bravia 9 and QN90F are premium mini-LED TVs that cost well over $2,000. Sony wins on processing and audio; Samsung wins on brightness and gaming. Neither is a bad choice — but they're built for different viewers.
Sony Bravia 9
The Bravia 9 is the better picture-processing TV; the QN90F edges ahead for gaming and extreme brightness.
Specs Comparison

Brightness and Local Dimming
RTINGS measured the Samsung QN90F at peak HDR brightness above 2,800 nits — among the brightest consumer TVs available. The Bravia 9 trails at around 2,500 nits, which is still class-leading for Sony.
Samsung uses a large number of local dimming zones with Neo Quantum Processor 8K upscaling. Sony's XR Backlight Master Drive is more conservative with zone count but more intelligent about when and how to engage dimming.
In practice, the Bravia 9 has fewer visible blooming artifacts despite lower zone count — Sony's processing is just smarter. The QN90F can bloom around bright objects in dark scenes more noticeably.
Upscaling and Picture Processing
Sony's Cognitive Processor XR uses scene detection and object recognition to apply different processing to different parts of the frame simultaneously. It's genuinely excellent — upscaled 1080p Blu-ray looks more film-like on the Bravia 9 than on competing TVs.
Samsung's Neo Quantum Processor is strong but more algorithmic. Sports content looks excellent on both sets, but movie content with dark scenes shows the Sony's superiority.
We'd lean toward the Bravia 9 for movie watching. The processing difference is visible in real content, not just lab tests.
Gaming
The QN90F is the better gaming TV. It supports 4K/144Hz across more inputs, has Samsung's Gaming Hub built in, and its HDMI 2.1 implementation is slightly more flexible.
The Bravia 9 does 4K/120Hz well, with two full-bandwidth HDMI 2.1 ports. For console gaming at 120fps it's fine; for PC gaming at 144Hz the QN90F is preferable.
Both support VRR and ALLM. Neither will bottleneck a modern console.
Audio
Sony's Acoustic Surface Audio+ on the Bravia 9 is one of the best built-in TV audio systems available. The actuators behind the panel create a genuinely immersive front soundstage — dialogue is uncannily well-placed.
Samsung's QN90F has conventional speakers with Dolby Atmos virtual processing. It's perfectly fine. But the Bravia 9's acoustic surface system is noticeably better without a soundbar.
If you're adding a soundbar anyway, audio becomes irrelevant. Both TVs pass Dolby Atmos faithfully.

FAQ
Which TV handles dark movie scenes better?
The Bravia 9, without question. Sony's processing knows when a scene is dark and manages the local dimming more carefully. Star fields, candlelit scenes, and night exteriors look cleaner on the Bravia 9.
Is 2,800 nits actually useful on the QN90F?
In a lit room with HDR content, yes. The extra brightness means highlights burn as intended — sun glinting off metal, stadium lights, explosions all look genuinely bright. In a dark room you'll have brightness limited by ABL anyway.
