LG C5 Series OLED evo TV vs Samsung S90F 42" OLED TV

Both are 42-inch 4K OLEDs with 120Hz panels, four HDMI 2.1 ports and Dolby Atmos, so the split comes down to HDR format support and software. The LG C5 adds Dolby Vision, a 144Hz VRR mode for PC gaming and a 5-year webOS update pledge, but owners report cluttered menus, ad-heavy webOS, remote failures and weak built-in dialogue. The Samsung S90F counters with HDR10+ and the cleaner Tizen system, yet it lacks Dolby Vision, so Dolby Vision discs and streams fall back to HDR10. Buyers rate the LG well overall; the Samsung's spec sheet is strong but it has fewer owner reports to lean on.

• Choose the LG C5 if you watch Dolby Vision movies, game on a PC at up to 144Hz, or want a TV that keeps getting webOS updates for years.
• Choose the Samsung S90F if you prefer Tizen's simpler interface and want HDR10+ support for Samsung-heavy streaming libraries.
