Product Snapshot


The HP U28 4K HDR monitor is a mid-tier display released in late 2020. It has got excellent features and is color accurate enough for content creators doing light design work. Users who love using multiple displays will appreciate how thin its bezels are, and those that have a tight workspace will love how easy its stand is to adjust in terms of height, swivel, tilt, and pivot angles. The display also boasts more connectivity options compared to the LG 27UN850-W, and weighing only 13.5 pounds, the display is relatively portable and easy to carry around. Read on for the rest of this HP U28 4K HDR monitor review to see whether or not it matches up with the best-rated computer monitors in the market.


our Verdict

The HP U28 4K HDR monitor is great for at-home design or professional work, with high color accuracy after calibration. However, its low contrast ratio and lack of local dimming mean its black levels are limited. It has wide viewing angles for comfortable group viewing, but its HDR capability might not be enough for those looking for a true HDR experience.
