Our take on the LG Class B4 Series 65" 4K Ultra HDR Smart OLED WebOS TV

The LG B4 is LG's entry-level 2024 OLED, a 65-inch 4K panel with the webOS smart platform and HDR10 support. OLED gives it per-pixel contrast, deep blacks and wide viewing angles that LED rivals in the same class cannot match. It runs at up to 120Hz with HDMI 2.1 ports, so it suits movie watchers and console gamers. Against the C4 it gives up some brightness and processing, but it keeps the core OLED picture and gaming features.

Questions and answers

Is the LG B4 worth it over the C4?
The B4 keeps OLED contrast and 120Hz gaming at a lower tier. The C4 is brighter and has better processing, so pick it if the room is bright or you want the best picture.
Does the B4 support 4K at 120Hz for consoles?
Yes. It has HDMI 2.1 ports that carry 4K at up to 120Hz, which suits PS5 and Xbox Series X.
Is OLED burn-in a real risk on this TV?
It can happen with static logos, tickers or game HUDs left on for long stretches. Vary content and use the screen-shift and logo-dimming settings.
What is in the box?
The TV, its stand, a remote and the power cable. A wall mount and HDMI cables are not included.
Does it run the major streaming apps?
Yes. webOS includes Netflix, Disney+, Prime Video, YouTube and the other main services.
How many HDMI ports does it have?
Four HDMI inputs, and the set supports HDR10 and Dolby Vision content.
