Our take on the 77-Inch Class OLED B4 Series TV with webOS 24

The LG B4 is LG's entry-level OLED, sold here in the 77-inch size. It uses a 4K OLED panel with per-pixel light control, so blacks are true black and contrast is effectively infinite, which is the main reason people choose OLED over LED. It runs webOS 24 with all the major streaming apps and LG's Magic Remote. Compared with LG's brighter C4 and G4, the B4 has lower peak brightness and a 120Hz panel instead of 144Hz, so it suits dark-room movie watchers more than sunlit living rooms.

Questions and answers

How does the B4 compare with the LG C4?
The C4 is brighter and has a 144Hz panel; the B4 is dimmer and tops out at 120Hz. Both are 4K OLEDs with four HDMI 2.1 ports, so the C4 mainly buys brightness and smoother motion.
Is the B4 good for gaming?
Yes. It has four HDMI 2.1 inputs, 4K at 120Hz, VRR and ALLM, which covers PS5 and Xbox Series X at high frame rates. It lacks the 144Hz mode of the C4.
Is a 77-inch OLED too big for an average room?
LG recommends sitting roughly 1.5 to 2 times the screen height away, which for a 77-inch set is about 8 to 10 feet. Closer than that, the picture can feel overwhelming.
Does it support Dolby Vision and Dolby Atmos?
Yes, it supports both Dolby Vision HDR and Dolby Atmos pass-through. Built-in speakers are modest, so a soundbar or receiver is worth adding.
What is in the box?
The TV, its stand, the Magic Remote and the power cable. A wall mount and HDMI cables are not included.
Will static logos burn in?
OLED can retain static images over long periods. The B4 includes pixel refresh and logo dimming to reduce the risk, but varied content is still safer than a single news channel all day.
Where is the 77-Inch Class OLED B4 Series TV with webOS 24 cheapest?
At korestorera, for $272.00, as of our latest check.
