LG C5 OLED evo 4K Smart TV vs LG B4 Series OLED TV

Both are 48-inch LG OLEDs with the same near-infinite contrast and wide viewing angles, so the picture fundamentals are close. The C5 is the step up: a brighter evo panel, the newer α9 Gen8 processor, four full 48Gbps HDMI 2.1 ports, 144Hz gaming with G-Sync and FreeSync Premium, and webOS 25 with LG's multi-year update pledge. The B4 is the older 2024 set with a 120Hz panel and a more basic processor, and it is the sensible pick if you mainly watch movies and stream and do not need the extra gaming headroom. Owners of both praise the OLED picture; C5 buyers single out the smoother 144Hz gaming and Dolby Vision movie performance.

• Choose the LG C5 if you game on a console or PC at high frame rates, want the brightest OLED picture LG makes at this size, or plan to keep the TV for many years and want the longer update support.
• Choose the LG B4 if you mostly watch films and streaming shows, game only casually, and would rather put the difference toward a soundbar or a larger screen size.
