    Questions and answers

    Which is better for a bright living room?
    The LG G4 OLED. Its OLED evo panel with Micro Lens Array is rated 150% brighter than the B4 series, so it holds up better against window light. The B5 is a standard OLED panel and will look dimmer in a bright room.
    Is the G4 worth $519 more than the B5?
    For picture quality, yes. The G4 adds a brighter evo panel, the Alpha 11 processor and a slimmer flush-mount design. If you mainly want screen size, the 77-inch B5 at $899.99 gives you more inches for less money.
    Which is better for gaming?
    The LG B5. Both run at 120 Hz, but the B5 lists NVIDIA G-Sync and AMD FreeSync support, and the G4 listing does not name either variable refresh format.
    Which has the bigger screen?
    The LG B5 in this listing, at 77 inches versus 55 inches for the G4. Check the exact model number before buying, since both series come in several sizes.
    Which lasts longer?
    Neither maker publishes a lifespan figure, so there is no clear winner. OLED panels can dim over years of heavy use, and the G4's brighter panel runs harder, but both carry the same LG warranty terms.
    Do both support Dolby Vision?
    Yes. Both list Dolby Vision HDR. The B5 also lists Dolby Atmos, and the G4 lists Wide Color Gamut.
