LG OLED B4 Series 4K Smart TV vs LG OLED42C5PUA 42" OLED TV

The C5 is the better TV of the two. It uses LG's brighter OLED evo panel with the Alpha 9 Gen8 processor, adds anti-glare coating, and reaches 144Hz for PC gaming, while the B4 tops out at 120Hz on the older α8 chip. The B4 still delivers true OLED blacks, four HDMI 2.1 ports and full gaming support, and it comes in larger sizes up to 83 inches, which the 42-inch C5 does not. Owners and reviewers consistently rate the C-series above the B-series on brightness and processing, and the C5's 4.4-out-of-5 owner rating reflects that. Buy the C5 for a bright room, a desktop or a serious gaming setup; buy the B4 if you want a big-screen OLED and can accept slightly lower brightness.

• Choose the LG B4 if you want a larger OLED screen size, up to 83 inches, and 120Hz gaming is enough for you.
• Choose the LG C5 if you watch in a bright room, game on a PC at up to 144Hz, or want the sharper processor and anti-glare screen.
