Samsung S90H 83" OLED 4K TV vs LG OLED evo AI 4K Smart TV

Both are 4K OLEDs with 120Hz panels, so picture fundamentals are close. The Samsung S90H is the more feature-loaded set: four HDMI ports, Wi-Fi 6E, FreeSync Premium Pro and G-Sync, Dolby Atmos with object tracking, and a bundled multi-year protection plan. The LG OLED evo is the safer pick if you want a well-established OLED line with broad size choices and Siri support. Owners of both praise OLED contrast and viewing angles; the Samsung leans brighter and more gaming-focused, while LG's evo panel is known for strong processing and a clean webOS interface.

  • Choose the Samsung S90H if you want the most gaming features, four HDMI inputs, Dolby Atmos, and a long included protection plan on an 83-inch OLED.
  • Choose the LG OLED evo if you want a proven OLED with Siri support and a choice of sizes from 48 to 83 inches.

Questions and answers

Which is better for gaming, the Samsung S90H or the LG OLED evo?
The Samsung S90H states FreeSync Premium Pro, G-Sync, VRR, ALLM and a game bar, so it covers both console and PC sync standards. The LG OLED evo is also a 120Hz OLED and plays games well, but its listing does not spell out the same sync features.
Which has better sound without a soundbar?
The Samsung S90H lists a 2.1 channel system with Dolby Atmos, object tracking sound and Q-Symphony. The LG listing gives no audio details, so the Samsung is the clearer choice for built-in sound.
Do both come in 83 inches?
Yes. The Samsung S90H is an 83-inch set, and the LG OLED evo is offered in 83 inches along with 48, 55, 65 and 77 inches. If you want a smaller screen, only the LG gives you that option.
Which lasts longer?
OLED panels on both are rated similarly for lifespan, and neither listing gives a panel hour rating. The Samsung includes a five-year Amber protection plan plus the one-year manufacturer warranty, which extends coverage beyond what the LG listing states.
Is the Samsung worth stepping up to over the LG?
If you want four HDMI ports, Wi-Fi 6E, Dolby Atmos and a long protection plan on a large OLED, the Samsung offers more. If you want a smaller size or Siri, the LG is the better fit.
Which works better with smart home assistants?
The Samsung S90H has Google Assistant and Amazon Alexa built in. The LG OLED evo lists Siri support. Pick based on which assistant your home already uses.
