What Customers Say

People with 2024 B‑series OLEDs admire the perfect blacks, infinite contrast and smooth motion that the OLED panel provides【175037205819526†L257-L360】. They like the accurate colours and good upscaling, and gamers appreciate the HDMI 2.1 features for low lag. But, the screen doesn’t get bright enough to overcome glare and reflections from windows are noticeable【175037205819526†L257-L360】. Some report occasional stutter due to the fast response time and find the built‑in sound underwhelming. For the price it delivers excellent picture quality but needs a dark room and an external speaker system.
