The Samsung QN90D is the 2024 step above the Q80D — a mini-LED TV with a significantly upgraded local dimming system, 144Hz gaming, and peak brightness around 2,000 nits. It's built for bright living rooms and gamers who want a complete HDMI 2.1 setup. The two standing trade-offs are Samsung's ongoing exclusion of Dolby Vision and Tizen OS's home-screen advertising.

"Had a Sony A80K before this. The brightness difference is insane — HDR content on the QN90D in my sun-facing living room actually looks like HDR. The Sony looked washed out by comparison."

"Gaming at 4K 120Hz on PS5 is flawless. Zero noticeable input lag, colours are accurate, and it never tore once in 40 hours of play. Best gaming screen I've owned."

"No Dolby Vision is a real thing you'll notice. About 60% of what I watch on Netflix is DV. It's fine in HDR10+ but you do feel like you're leaving something on the table."

The absence of Dolby Vision is the most frustrating spec gap owners in r/4kTV consistently raise — with Netflix, Disney+, and Apple TV+ all prioritizing Dolby Vision delivery, Samsung's holdout position noticeably affects daily streaming quality.

Dirty screen effect and banding on grey-field test patterns is a recurring topic in the QN90D owners thread — some units show visible horizontal or vertical banding in low-contrast scenes like sports broadcasts with large uniform backgrounds.

Tizen OS home-screen ads are a nearly universal complaint among Samsung TV owners — promotional content appears between app icons even at this price point, and multiple firmware updates have reportedly re-enabled sponsored content after users disable it.
Source: Reddit r/TelevisionsOwner consensus on the QN90D places it as the best-value premium mini-LED TV Samsung has released — praise concentrates on exceptional brightness, complete gaming spec sheet, and the meaningful step up in local dimming quality over the Q80D. The complaints are the same ones Samsung buyers face across the lineup: no Dolby Vision, Tizen ads, and occasional panel uniformity issues on some units. For a bright living room paired with a PS5 or gaming PC, nearly every owner review rates the QN90D as worth it at this price.
