LG C1 55" 4K OLED TV vs Samsung S90C OLED 4K TV

The LG C1 is the better pick for most people deciding between these two. It has four full-bandwidth HDMI 2.1 ports, G-Sync and FreeSync support, Dolby Vision, and a 55-inch size that fits more rooms. The Samsung S90C is a strong rival with brighter QD-OLED color and a slimmer design, but it starts at 65 inches and its ratings trail the LG's. Owners of both praise the picture; LG owners more often mention the gaming feature set, Samsung owners the brightness.

  • Choose the LG C1 if you game on a console or PC and want four HDMI 2.1 ports, G-Sync, Dolby Vision, and a 55-inch size that fits a smaller room.
  • Choose the Samsung S90C if you want a larger 65-inch or 77-inch screen, brighter quantum-dot OLED color, and a thinner design.

  • BrightnessCriticisedViewers say it struggles in bright rooms and with HDR highlights.
  • SoundCriticisedThe 40W speakers are described as weak, so many add a soundbar.

Samsung S90C OLED 4K TV

Questions and answers

Which is better for gaming, the LG C1 or the Samsung S90C?
The LG C1. It has four HDMI 2.1 ports, G-Sync and FreeSync Premium, and Dolby Vision for supported games. The Samsung has 120Hz and FreeSync but no G-Sync certification and no Dolby Vision.
Which has the better picture?
The Samsung S90C is brighter and more colorful thanks to its quantum-dot layer, which helps in a bright room. The LG C1 still delivers perfect blacks and holds color at wide angles. In a dark room the gap is small.
Does the Samsung S90C support Dolby Vision?
No. It supports HDR10, HLG and HDR10+, so Dolby Vision titles play in HDR10 instead. The LG C1 supports Dolby Vision.
Which lasts longer, an OLED or a QD-OLED TV?
Both use organic light-emitting materials that can fade over years of heavy use. Neither maker publishes a lifespan figure. Avoiding a static logo or ticker at maximum brightness for hours a day is the main way to protect either panel.
Is the Samsung worth stepping up to for a bigger screen?
Yes, if you want 65 or 77 inches. The LG C1 here is 55 inches only. The Samsung adds brightness and Dolby Atmos, but you give up Dolby Vision and G-Sync.
Which is easier to set up with a soundbar and consoles?
The LG C1. Its four HDMI 2.1 ports let you connect a console, PC and soundbar without giving up 4K at 120Hz. The Samsung also has four ports, but only one is marked for eARC.
