LG OLED evo C4 42-Inch 4K Smart TV vs Samsung 42” S90H OLED 4K Smart TV

The LG C4 is the better all-round pick for most people, especially gamers on PC or console, thanks to four full-bandwidth HDMI 2.1 ports, G-Sync and FreeSync certification, and Dolby Vision. The Samsung S90H counters with a much higher 165Hz refresh rate, HDR10+ support and a glare-free coating that the LG lacks. Both are 42-inch OLEDs with 4K panels and 20W speakers, so the choice comes down to whether you want Dolby Vision and proven gaming certification or the faster panel and anti-glare screen.

  • Choose the LG C4 if you watch Dolby Vision movies, game on a PC with an Nvidia card, or want the model with the longer track record and more owner reviews.
  • Choose the Samsung S90H if you game at high frame rates, watch in a bright room where reflections bother you, or want HDR10+ for Samsung and Amazon content.

Questions and answers

Which is better for console gaming?
Both handle PS5 and Xbox Series X at 4K 120Hz. The LG adds G-Sync certification and Dolby Vision gaming, while the Samsung's 165Hz panel mainly benefits PC players who can push past 120fps.
Which handles a bright room better?
The Samsung S90H. Its Glare Free coating cuts reflections, while the LG C4 has a glossy screen with no anti-glare treatment.
Do I lose much without Dolby Vision on the Samsung?
Yes, if you watch Dolby Vision discs or stream from services that use it. The Samsung falls back to HDR10 or HDR10+, which still looks good but is not the same master.
Is the Samsung worth stepping up to over the LG?
Only if the higher refresh rate or anti-glare screen matters to you. Otherwise the LG's Dolby Vision, G-Sync and larger review base make it the safer pick.
Which lasts longer?
Both use OLED panels with similar lifespans. The LG has a longer track record of owner reports, while the Samsung is a newer 2026 model with less long-term data.
Which is better for movies?
The LG C4, because it supports Dolby Vision and Dolby Atmos, which most streaming films and discs use.
