The video upscaling and processing are equally impressive; the AI-enhanced Hi View Pro picture processing engine upscaled lower-resolution content in a highly effective manner. The U8N also displays native 4K content with plenty of crisp detail, while the processing minimises unwanted artefacts in heavily compressed streaming material or low-quality digital TV channels.
The overall motion handling is also excellent, with the panel’s ability to handle frame rates up to 144Hz undoubtedly playing an important role. There’s no motion blurring in fast-paced sports action and the U8N handles 24p content without introducing additional judder.

Hisense U8N review: HDR performance
The Hisense U8N’s Mini LED Pro backlight doesn’t just offer thousands of dimmable zones for improved local dimming, it also delivers a significant increase in peak luminance. Hisense is conservative in its marketing, claiming 3,000 nits on a 10% window and 700 nits on a full field pattern. I measured the 65in U8N at an incredibly bright 3,500cd/m2 and 900cd/m2.
Of course, having all this brightness is pointless if the HDR image accuracy is poor, and here the U8N impresses with a greyscale composed of equal amounts of red, green and blue. The tone mapping matches the PQ curve closely across the range, which means the HDR image looks good with content graded at 1,000 nits, ensuring no crushed blacks or clipped highlights.
However, this tone mapping accuracy isn’t the case with 4,000 and 10,000 nits graded material, and running through my various tests revealed differences in performance. While Dolby Vision looks excellent, as did HDR10 content graded at 1,000 nits, the same footage in HDR10+ content does show some signs of clipping in highlights, as does content graded at 4,000 and 10,000 nits.
The use of quantum dots allows the U8N to cover 97% of the DCI-P3 colour gamut, and while generally good, some colours could be more accurate, with magenta skewing towards blue, and red being undersaturated. These minor errors aren’t apparent with actual viewing material, and in general, this TV delivers vibrant and saturated colours that retain plenty of visual impact.
