Samsung QN55QN80F Neo QLED 4K TV vs Toshiba Z670R 55-Inch TV

Both are 55-inch mini-LED QLED sets with 144Hz panels, so the picture fundamentals are close. The Toshiba Z670R pulls ahead for movie and console gaming because it adds Dolby Vision IQ, HDR10+ Adaptable, HDMI 2.1 and FreeSync Premium, and it runs Fire TV. The Samsung QN80F counters with a brighter Neo QLED backlight, four HDMI ports, Wi-Fi 5, Bluetooth 5.3 and Samsung's Tizen platform, which owners and reviewers generally rate as smoother and better supported. Buy the Samsung for a bright room and polished smart TV; buy the Toshiba for Dolby Vision content and gaming features.

  • Choose the Samsung QN80F if you want the brighter Neo QLED picture, four HDMI inputs and Samsung's Tizen smart platform in a bright living room.
  • Choose the Toshiba Z670R if you watch Dolby Vision movies or play on a PS5 or Xbox and want HDMI 2.1, FreeSync Premium and Fire TV built in.

Questions and answers

Which is better for a bright living room?
The Samsung. Its Neo QLED backlight is built for higher brightness, so reflections and daylight wash out the picture less. The Toshiba is fine in a dim room but loses punch in strong light.
Which is better for PS5 or Xbox gaming?
The Toshiba. It has HDMI 2.1, ALLM and FreeSync Premium, which the Samsung does not list. The Samsung's 144Hz panel is smooth, but without HDMI 2.1 you give up 4K at high frame rates.
Does the Samsung support Dolby Vision?
No. It handles HDR10+ and HLG. Dolby Vision movies from discs or streaming will play in HDR10 instead, so the Toshiba is the pick if Dolby Vision matters to you.
Which smart TV system is better?
Tizen on the Samsung is faster and cleaner, and reviewers rate its app support highly. Fire TV on the Toshiba has a wider app store and Alexa, but its home screen carries more ads.
Is the Toshiba worth stepping up to over the Samsung?
Only if Dolby Vision or console gaming features matter. Otherwise the Samsung's brighter panel and four HDMI ports make it the more balanced set for general viewing.
Which lasts longer?
Both use similar mini-LED panels with long-rated backlights, so neither clearly outlasts the other. Samsung's software support has a longer track record; Fire TV updates depend on Toshiba.
