LG OLED BX 4K TV review: Anything but entry-level


The BX is the 2020 entry-level offering in LG’s OLED 4K TV line-up. With a tempting price tag, and a raft of advanced features, it hopes you won’t notice the step-down Alpha 7 picture processor behind the panel. 

Not that there’s anything particularly discounted about the BX. LG’s third-gen Alpha 7 processor is still very capable, and you get the AI goodies found on LG’s CX range. 


  • 4x HDMI, 2x USB
  • Wi-Fi and Bluetooth

Classic and classy, a razor thin bezel and panel make the BX a high-tech headturner.

LG isn’t afraid to push the boat out when it comes to industrial design – just consider its Gallery, Wallpaper and rollable models – but the BX is obviously more conservative. The panel is wafer thin, though, swelling only to house electronics and inputs. 

The central pedestal, with subtle brush finish, will look good with most AV furniture, and the build quality is fine.

Round the back are four HDMI ports, which are worth a closer look. Two of these are v2.1 and support 4K at 120Hz – specifically 40Gbps at 10-bit 4:4:4 – so they’re enabled to make the most of the PlayStation 5 and Xbox Series X when they’re in full flight. The remaining HDMI ports are regular 8-bit 4K/60p inputs. Naturally, there’s also eARC/ARC support.

They’re joined by a trio of USB ports, Ethernet, optical, and analogue digital audio outputs, plus a CI card slot should you live somewhere that needs one. 

The screen comes with LG’s standard cursor-based Magic Remote control. This Bluetooth pointer has a distinctive thumbwheel control plus dedicated buttons for Netflix, Prime Video, and Rakuten TV.

Smart OS

  • LG webOS smart platform
  • Google Assistant
  • Works with Alexa 
  • Freeview HD

Smart connectivity comes via LG’s webOS smart platform, complete with a full larder of OTT streaming services. All the key players are stocked, including Netflix, Prime Video, Disney+, Apple TV, Britbox, Twitch and YouTube.

But for everyday catch-up, the pickings are more sparse. The set offers both terrestrial and single satellite tuners, but disappointingly there’s no Freeview Play, so we get vanilla Freeview HD instead, which means no integrated catch-up. You’ll need to turn to an exterior box to keep up with your soaps. Unless you’re an Eastenders fan, as BBC iPlayer is provided.

ThinQ AI implementation offers digital assistant integration, for voice control of volume and channels, and it’s also compatible with Apple’s Homekit and AirPlay 2.

AI has been knitted into the operating system, to the point where it warrants its own AI Service menu. Here you can toggle Adaptive Audio and AI Picture Modes. Both use machine learning techniques to maximise performance. Squeezing the best from an LG OLED often seems like a daunting task, but leaving the screen on AI autopilot makes a lot of sense.
