LG OLED evo C4 65-Inch TV vs Samsung S90H OLED TV

The LG C4 is the safer all-round pick for movie and mixed viewing, with four full-bandwidth HDMI 2.1 ports, Dolby Vision, and a five-year webOS update pledge. The Samsung S90H wins on bright-room viewing thanks to its Glare Free coating and pushes higher refresh for gaming, but it lacks Dolby Vision and gives up some port flexibility. Both are 65-inch 4K OLEDs with 120 Hz panels and strong owner ratings; the C4 has the larger review base, the S90H the higher average score.

  • Choose the LG C4 if you watch movies in a dim room, want Dolby Vision and Dolby Atmos, and need four HDMI 2.1 ports for a console plus a soundbar and PC.
  • Choose the Samsung S90H if your room is bright, reflections bother you, and you want the smoother high-refresh gaming panel with Samsung's glare-free coating.

Questions and answers

Which is better for a bright living room?
The Samsung S90H. Its Glare Free coating suppresses reflections that the glossy LG C4 shows. The C4 is the better pick in a dim or dark room.
Does the Samsung S90H support Dolby Vision?
No. It handles HDR10, HDR10+ and HLG. The LG C4 supports Dolby Vision, which matters for Dolby Vision movies and shows on major streaming services.
Which is better for gaming?
The S90H has the higher refresh panel, but the C4's four HDMI 2.1 ports and G-Sync certification make it easier to connect a console, PC and soundbar together. Pick the C4 for multi-device setups, the S90H for the smoothest panel.
Which lasts longer?
LG commits to five years of webOS updates through its Re:New program. Samsung's Tizen update window is shorter. OLED panel life is similar on both, and burn-in risk is low with normal mixed viewing.
Is the S90H worth stepping up to over the C4?
Only if bright-room viewing or the higher refresh rate matters most to you. If you want Dolby Vision, more full-bandwidth HDMI ports and longer software support, the C4 is the better fit.
Do either have anti-glare screens?
The S90H does, through Samsung's Glare Free coating. The LG C4 does not; its screen is glossy and reflects light sources behind the viewer.
