The Samsung QE42S90F is a 42-inch 4K OLED listed at £759.00 with a 4.5 out of 5 rating, sitting fifth in this guide. It is the smallest screen on the page and the cheapest 42-inch set named in it — £340 below the £1,099 LG 42-inch C6 the guide also lists. The five selling points cover the usual OLED ground: self-bright OLED for blacks and contrast, 4K upscaling from the Neural Quantum Gen3 processor, Object Tracking Sound with Dolby Atmos, gaming up to 144 Hz with Motion Xcelerator and FreeSync Premium Pro, and four HDMI 2.1 inputs.

The numbers on the page do not all agree with each other. The listing says 56 ratings, but the star bars it prints add up to 100 (74 five-star, 16 four-star, 3 three-star, 2 two-star, 5 one-star) — and a 4.5 average fits that 100-bar spread, not 56. The spec table gives "Full Array Local Dimming" as the backlight configuration on a panel the same table calls self-luminous, which is difficult for an OLED that emits its own light. The smart platform is Tizen in the selling points and Google TV in the internet applications line. Everything on this page is taken from the Amazon listing — we have not tested this television.
