Samsung S90H OLED 4K Smart TV vs Roku Pro Series OLED

The Samsung S90H is the better pick for picture quality: true OLED with per-pixel contrast, a glare-free coating, four HDMI ports and a 165Hz gaming mode with G-SYNC and FreeSync Premium Pro. The Roku Pro Series is a mini-LED QLED, so it goes brighter in a sunlit room and comes in 55, 65 and 75 inches, but it has only two HDMI ports and its blacks can't match OLED. Owners rate both highly; the Samsung's 4.8 from 1,400 ratings edges the Roku's 4.7 from 609.

  • Choose the Samsung S90H if you want the deepest blacks, the widest viewing angles and the most gaming connections in a smaller room.
  • Choose the Roku Pro Series if you need a big screen in a bright room and prefer Roku's simple home screen.

Prices

  • Samsung S90H OLED 4K Smart TV: $997.99 at Amazon (last seen Nov 13)
  • Roku Pro Series OLED: $999.99 at eBay (last seen Nov 12)
  • Difference: the Samsung S90H OLED 4K Smart TV is $2.00 cheaper than the Roku Pro Series OLED at the latest prices (Nov 12 and Nov 13)

What reviewers say

  • 4.8 / 51,400 ratings

Owners rate the S90H highly, at 4.8 out of 5 from 1,400 ratings. Praise centers on picture quality and the glare reduction, while complaints focus on brightness in very bright rooms and the price gap to cheaper OLEDs.

  • BrightnessMixedViewers say it is bright enough for most rooms but dimmer than top LCDs in direct sun.
  • GamingPraisedThe 120 Hz panel, VRR and low latency are called out as smooth for consoles.

Questions and answers

Which is better for a bright living room?
The Roku Pro Series. Its mini-LED backlight pushes higher brightness to fight daylight, while the Samsung's Glare Free coating cuts reflections but can't match that peak output.
Which has better picture quality for movies?
The Samsung S90H. OLED turns each pixel off for true black, so dark scenes keep detail without blooming, and off-angle seats look the same.
Which is better for gaming?
The Samsung S90H. It has four HDMI ports, a 165Hz motion mode, G-SYNC and FreeSync Premium Pro. The Roku covers 120Hz with FreeSync Premium Pro, ALLM and VRR but only two HDMI inputs.
Does the Roku Pro Series come in a 42-inch size?
No. It comes in 55, 65 and 75 inches. The Samsung S90H is a 42-inch set, so it fits smaller rooms and desks.
Which lasts longer?
Both should run for years. OLED pixels can lose brightness gradually with constant static logos, while mini-LED backlights avoid that risk but can develop uneven dimming zones over time.
Is the Samsung worth stepping up to over the Roku?
If you want OLED blacks, four HDMI ports and stronger gaming support in a compact size, yes. If you need a 65- or 75-inch screen or a very bright room, the Roku is the better fit.
