LG OLED C6 65-inch TV vs Samsung S84H 65" OLED 4K TV

Both are 65-inch 4K OLEDs with 120Hz panels and four HDMI inputs, so the core picture is close. The LG C6 pulls ahead on gaming and HDR: it adds Dolby Vision, VRR with G-Sync and FreeSync Premium, a faster refresh mode, and a brighter evo panel with the a11 Gen3 processor. The Samsung S84H counters with Tizen, Bixby and Alexa built in, and HDR10+ instead of Dolby Vision. Buyers who watch a lot of Dolby Vision movies or play on PC and console should take the C6; buyers deep in the Samsung and SmartThings ecosystem will be happy with the S84H.

  • Choose the LG C6 if you want Dolby Vision, the widest gaming feature set, and the brighter OLED evo panel.
  • Choose the Samsung S84H if you want Tizen with Bixby and Alexa and already run a Samsung smart home.

Questions and answers

Which is better for gaming, the LG C6 or the Samsung S84H?
The LG C6. It lists VRR, NVIDIA G-Sync, AMD FreeSync Premium, a 0.1ms response time and a refresh rate up to 165Hz. The S84H tops out at 120Hz with no listed VRR or sync certification.
Does the Samsung S84H support Dolby Vision?
No. It supports HDR10+ only. The LG C6 supports Dolby Vision, HDR10 and HLG, so Dolby Vision movies and shows will look their best on the LG.
Which has better sound out of the box?
The LG C6. It has a 2.2-channel system with Dolby Atmos and AI Sound Pro. Samsung does not list comparable speaker details for the S84H, so a soundbar is a safer bet there.
Is the LG C6 worth stepping up to over the S84H?
If you watch Dolby Vision content or game on PC or console, yes. The C6 adds Dolby Vision, VRR with G-Sync and FreeSync, a brighter evo panel and more sound channels. If you mainly use Samsung apps and SmartThings, the S84H covers the basics.
Which smart platform is easier to use?
Both are polished. Tizen on the S84H is simple and app-rich with Bixby and Alexa. webOS on the C6 adds Gemini and Copilot AI search and the Magic Remote pointer, which some people prefer.
Do both have four HDMI inputs?
Yes, both list four HDMI inputs. The LG C6 also lists two USB ports, Ethernet and optical audio, which helps if you connect a soundbar or wired network.
