LG OLED evo C4 42-Inch 4K Smart TV vs Samsung S90F OLED 4K Smart TV

Both are 42-inch 4K OLEDs with four HDMI 2.1 ports, and both are strong for gaming and film. The LG C4 is the safer pick for movie watchers and mixed use: Dolby Vision support, four G-Sync and FreeSync certified ports, and a long track record of owner praise for picture accuracy. The Samsung S90F edges ahead for competitive gamers with a 144Hz panel and Motion Xcelerator, and its anti-glare coating handles bright rooms better. Build and panel quality are close; the LG's stand and finish feel slightly more solid, while the Samsung ships with a solar-powered remote.

  • Choose the LG C4 if you watch Dolby Vision movies, want proven G-Sync and FreeSync gaming support, or value a long record of owner satisfaction.
  • Choose the Samsung S90F if you play fast competitive games at up to 144Hz or watch in a bright room where glare matters.

Questions and answers

Which is better for console gaming?
The Samsung S90F has the edge for competitive play with its 144Hz panel and Motion Xcelerator. The LG C4 is still excellent at 120Hz and adds G-Sync certification, which helps if you also game on a PC.
Does the Samsung S90F support Dolby Vision?
No. It supports HDR10+ and HDR10 but not Dolby Vision. The LG C4 supports Dolby Vision, so it is the better choice if you watch Dolby Vision films and shows.
Which handles a bright room better?
The Samsung S90F. Its anti-glare treatment cuts reflections, while the LG C4 has a glossy panel with no anti-glare coating. In a dark room the difference is small.
Is the LG C4 worth stepping up to over the Samsung?
They sit in the same class, so it is not a step up either way. Pick the LG for Dolby Vision and proven G-Sync support, and the Samsung for 144Hz and glare handling.
Which lasts longer?
Both use OLED panels with similar lifespans, and neither brand publishes a clear advantage. Owners of both report years of trouble-free use; burn-in risk is low with varied content and the built-in screen care features.
Do either have ATSC 3.0 tuners?
The Samsung S90F does not list ATSC 3.0 support. The LG C4's listing does not confirm it either, so check the tuner if you rely on over-the-air next-gen broadcasts.
