Our verdict
The B5 is an OLED TV: each pixel makes its own light and can switch fully off, so dark film scenes get deep blacks and bright details stand out when the room lights are low. The 65-inch model supports compatible 4K games at 120Hz, meaning up to 120 pictures a second, which looks smoother and feels more responsive with a PS5, Xbox Series X or gaming PC. LG lists four HDMI inputs, all supporting 4K 120Hz, so a console does not have to share a socket with every other box. The built-in speakers are 20W stereo. The recorded price is £1,199 for the 65-inch model, and it has not been refreshed since 1 August 2026.
Buy it if
- You enjoy films with the lights turned down
- You want compatible high-frame-rate console gaming
- You need to connect several devices and a soundbar
Skip it if
- You mainly need an inexpensive television for occasional use
- Direct sunlight falls on the screen throughout your viewing time
- You expect cinema-style bass without additional speakers
How it would fit your home
Let a dark scene keep its atmosphere
OLED can keep black areas dark beside bright objects, so a night scene need not become a grey wash. Your room still matters: check reflections from your usual seat, especially if a window or lamp faces the screen.
Give supported games a smoother feel
The 120Hz screen can show more motion updates in compatible games. It does not make every game run at 120 frames per second. Check the game's available modes; choosing faster motion may also change the picture detail it renders.
Leave your equipment connected
LG lists four HDMI inputs supporting 4K 120Hz. A soundbar using the eARC connection (the HDMI socket that sends sound back to the soundbar) occupies HDMI 3, leaving three other sockets. This is useful if you switch between two consoles and a TV box.
The details, in plain English
Picture in a dark room
On an OLED screen each pixel lights itself and can switch fully off, so black areas stay properly dark next to bright objects and a night scene does not turn into a grey wash. That makes the B5 best suited to evening viewing with the lights low. In a room where a window or lamp faces the screen, reflections can still spoil the effect, so check the view from your usual seat.
Gaming
The 120Hz screen means the picture can update up to 120 times a second in compatible games, which looks smoother and makes the controls feel more immediate. Support for 4K at 120Hz applies on all four HDMI inputs, according to LG. That said, it depends on the game: many do not offer a 120 frames-a-second mode, and choosing it can reduce picture detail.
Connections
LG lists four HDMI inputs that support 4K 120Hz. eARC on HDMI 3 sends sound from the TV to a compatible soundbar with a single cable. With a soundbar on HDMI 3, three sockets remain for a games console, a second console and a TV box, so you rarely need to swap cables.
Listen at your normal volume
The listed 20W stereo speakers give you sound straight out of the box. Before adding a soundbar, try speech at the volume you use in the evening. Buy extra audio for a problem you can hear, rather than because a sound-format badge suggests you must.
Strengths and drawbacks
What it does well
- OLED screen: deep blacks and strong contrast in dark film scenes

What to watch out for

Solves: 20W stereo speakers are not a separate surround-sound system
LG US80TR Reviewed by us
Adds actual rear speakers and a bass box when the named limit of stereo TV sound matters to you. This is for a wanted surround setup, not a speech-only purchase.
Check first: Needs room and power near the sofa for rear speakers. The review says to skip if speech alone matters or you want few boxes.
