The LG BX line is the Korean model’s OLED honeypot flatscreen, priced to shift with a specification that’s solely barely denuded in comparison with its CX stablemates.

It sports activities a third-gen Alpha 7 processor (sibling LG screens use Alpha 9 picture-processing silicon), albeit with AI smarts to reinforce readability and enhance the consumer expertise.

LG’s much-lauded webOS good platform enjoys an AI improve and comes with a full fist of streaming companies, however there’s no Freeview Play. Consequently, the BX lacks key UK catch-up TV apps, though iPlayer is on board.

The BX ships with the newest iteration of LG’s cursor-based Magic Distant management; a Bluetooth pointer with thumbwheel management and devoted buttons for Netflix, Prime Video and Rakuten (accessed through a Films button).


Whereas the shortage of Freeview Play – and the following absence of all the standard catch-up TV apps – somewhat dents the BX’s mainstream attraction, it’s straightforward to treatment the omission with a media streamer or TV field.

  • Delivers excellent HDR highlights

The BX could ostensibly be an “entry-level” LG OLED set, however it’s nonetheless higher specified – at the least with regards to next-gen gaming – than OLED rivals costing considerably extra.

Whereas 4K@120fps has but to show itself as a show possibility, having it accessible will definitely be welcomed by consumers desperate to tick containers.

The Alpha 7 processor doesn’t evaluate with what the Alpha 9 is ready to ship when it comes to refinement and finesse.
