Amazon isn’t messing about when it comes to affordable entertainment, no matter the screen size. The firm’s Fire TV 4K TV line-up just got a major shot in the arm at its annual product launch event, promising faster processing and higher brightness at a still-sensible price point. Revealed alongside new colour screen Kindles, the refreshed Fire TV Omni QLED series has double the number of local dimming zones as the outgoing model, for a significant 60% hike to screen brightness. A new picture processor is apparently 40% faster than before, which is enough oomph to get the most out of Alexa+. The Fire TV Omni QLED series will be available in 50, 55, 65 and 75in screen sizes, with US prices starting from $480.
