The Samsung Odyssey OLED G81SF takes 10th place in this guide. It is the 27-inch 4K QD-OLED of the group: 3840 x 2160 native resolution, 240 Hz, 0.03 ms (G/G), FreeSync Premium Pro and G-Sync Compatible, listed at £529.00 — which is £70 below the £599.00 27-inch 4K OLED Gigabyte named in this guide.

Two things on the page are harder to reconcile. The listing shows 58 ratings and a 3.8 out of 5, but the star breakdown beside it adds up to 100 (15 one-star, 15 two-star, 3 three-star, 7 four-star, 60 five-star). And the reviews carried on the page describe a 32-inch screen and a £700 price, with 3 ms GTG and 'HDR Peek 1000', while the product data says 27 inches, £529.00, 0.03 ms and 250 Candela for image brightness. Everything on this page comes from the Amazon listing as it stands; we have not tested this monitor.
