Samsung 77" OLED 4K TV vs LG OLED AI B5 4K Smart TV (2025)
Both are 77-inch OLEDs, but they are not equals. The Samsung S95H is the brighter, more gaming-focused QD-OLED set, and at $1,399.00 at Echo Audio as of November 3 it is also the cheaper of the two. The LG B5 is a solid entry-level OLED at $1,499.99 as of October 28, but it gives up brightness and refresh rate. Buy the Samsung unless you specifically want LG's webOS and its assistant support.
