Samsung S90F OLED TV vs Roku Plus Series 65" 4K QLED TV

The Samsung S90F is the better TV for picture quality and gaming. Its OLED panel gives per-pixel contrast, 144Hz refresh and four HDMI 2.1 ports, and reviewers consistently praise its color and low input lag. The Roku Plus Series is a solid QLED Mini-LED set with Dolby Vision and the simple Roku interface, but it tops out at 60Hz and lacks HDMI 2.1, so it suits casual viewing more than fast gaming. Owners of both rate them well; the Samsung costs more because it does more.

  • Choose the Samsung S90F if you watch movies in a dark room, play fast games, or want the best contrast and motion a 65-inch TV can give.
  • Choose the Roku Plus Series if you want a bright, easy-to-use 4K TV with Dolby Vision and the Roku interface, and you don't need 120Hz gaming.

What reviewers say

Samsung S90F OLED TV

  • 4.6 / 5Google Shopping · 2,700 ratings

Reviewers and owners consistently praise the S90F's picture: vivid color, deep contrast and brightness that impresses people coming from LED sets. Gamers like the fast motion and low input lag, and setup is called quick. Complaints center on the reflective panel coating and a Game mode that needed a USB update to restore.

What people mention
  • Picture qualityPraisedOwners and reviewers call the color vivid and the contrast deep, especially against older LED TVs.
  • GamingMixedLow input lag and fast motion are praised, but some units needed a USB update to restore Game mode.
  • Panel coatingCriticisedThe glossy finish reflects room light, and at least one owner called the coating awful.
  • BrightnessPraisedHDR highlights are bright enough that upgraders notice the jump from LED sets.
A reviewer's verdict
  • CNET

    The Samsung S90F boasts excellent image quality and fast motion for gamers, but it is expensive and lacks the step-up model's glare-free coating.

Roku Plus Series 65" 4K QLED TV

  • 4.6 / 5503 ratings

Rated 4.6 out of 5 from 503 ratings, the set is generally well liked for its picture quality at the price and for Roku's easy interface. Complaints tend to center on black levels and motion rather than on the software.

What people mention
  • Picture qualityPraisedOwners say colors are vivid and accurate for the money, especially with Dolby Vision content.
  • Black levelsCriticisedDark scenes look washed out because the panel has no local dimming.
  • MotionMixedThe 60 Hz refresh rate is fine for most shows but shows blur in sports and fast action.

Questions and answers

Which is better for gaming, the Samsung S90F or the Roku Plus Series?
The Samsung S90F. It has a 144Hz panel, four HDMI 2.1 ports and very low input lag. The Roku Plus Series is limited to 60Hz and has no HDMI 2.1 features.
Which has better picture quality in a dark room?
The Samsung S90F. OLED pixels switch off individually, so blacks are truly black and contrast is near-infinite. The Roku's Mini-LED backlight has no local dimming, so dark scenes look grayer.
Does the Roku Plus Series support Dolby Vision?
Yes. It supports Dolby Vision, HDR10+ and HLG. The Samsung S90F supports HDR10, HDR10+ and HLG but not Dolby Vision.
Which is brighter in a sunny room?
The Roku Plus Series is built around a bright Mini-LED backlight, which helps in well-lit rooms. The S90F reaches about 1,162 nits in HDR but has a glossy coating some owners dislike.
Is the Samsung S90F worth stepping up to over the Roku?
If you game, watch movies in the dark, or want better motion and sound, yes. If you mainly stream shows in a bright room and want a simple interface, the Roku covers it.
Which lasts longer?
Both should last many years. OLED pixels can dim over time with static content, while LED backlights avoid burn-in but can develop uneven lighting. Neither brand publishes a lifespan figure.
