LG C5 OLED evo 4K Smart TV vs Samsung S90H OLED 4K TV (65")

The LG C5 is the better all-round OLED for most people: four full HDMI 2.1 ports, Dolby Vision, and a 55-inch panel that owners rate highly for picture and setup. The Samsung S90H wins on size and motion, with a 65-inch screen and a 165Hz refresh rate, plus a glare-free coating that holds up in bright rooms. Neither is a weak TV; the choice comes down to whether you want Dolby Vision and four gaming-ready ports or a bigger, faster, brighter-room panel.

  • Choose the LG C5 if you want Dolby Vision, four HDMI 2.1 inputs for a console and PC, and the most consistent owner feedback in this pair.
  • Choose the Samsung S90H if you sit farther back, watch in a bright room, and want the larger 65-inch panel with a 165Hz refresh rate.

  • SoundMixedThe built-in speakers are called decent for a TV, not a substitute for a soundbar.

Questions and answers

Which is better for gaming, the LG C5 or the Samsung S90H?
The Samsung S90H has the higher refresh rate at 165Hz, which suits fast PC play. The LG C5 has four confirmed HDMI 2.1 ports and VRR up to 144Hz, so it handles a console, a PC and a soundbar without swapping cables. Pick the LG for port flexibility, the Samsung for the highest frame rates.
Does the Samsung S90H support Dolby Vision?
No. It supports HDR10, HDR10+ and HLG. The LG C5 adds Dolby Vision, which matters if you watch Dolby Vision movies and shows and want the format handled natively.
Is the 65-inch Samsung worth stepping up to over the 55-inch LG?
If your seating distance is around 8 feet or more, the extra 10 inches on the Samsung makes a real difference. If you sit closer or want Dolby Vision and four full 2.1 ports, the smaller LG is the better fit.
Which handles a bright room better?
The Samsung S90H. Its glare-free screen is built to cut reflections from windows and lamps, and it pairs that with a bright OLED panel. The LG C5 has an anti-glare coating but is the weaker of the two in a sunlit room.
Which TV is easier to set up?
Both are straightforward, but LG owners note the menus have many picture and sound options to work through. The Samsung's Tizen setup is simpler, and its assistants are built in. Either way, plan for two people when lifting or mounting.
Do both have four HDMI ports?
Yes, both list four HDMI inputs. The LG C5 specifies all four as HDMI 2.1 with 4K 120Hz, eARC, VRR and ALLM. The Samsung lists four ports but confirms fewer as full 2.1, so check which ones you need for a console or PC.
