Samsung S90H 77" OLED 4K TV vs LG OLED evo G5 4K Smart TV

Both are 77-inch-class OLEDs with glare-free panels and 165Hz gaming, so the choice comes down to ecosystem and brightness. The LG G5 uses a brighter evo panel with a gallery-style wall mount and a longer track record; owners and reviewers consistently praise its punch in bright rooms. The Samsung S90H runs Tizen, adds HDR10+ and a 2.1-channel 40W speaker system, and its 4.9 rating from 866 buyers is strong but from a smaller sample than LG's 9,200. Buy the LG if you want the brightest picture and the most-proven OLED; buy the Samsung if you live in Tizen and want HDR10+ and better built-in sound.

• Choose the Samsung S90H if you want Tizen, HDR10+ support and stronger built-in 2.1-channel sound in a slim OLED.
• Choose the LG G5 if you want the brightest evo OLED panel, a gallery-style wall mount and the model with the longest owner track record.
