Rated 1 out of 5 by no-more-HP from Monitor loses connection after 1 hour of use Monitor keeps losing USB-C connection. We only used this for an hour or two and all of a sudden it loses the connection. Just like a numb of reviewers ha stated I regret purchasing this monitor.

Rated 1 out of 5 by Anonymous from Very disappointed The web said it was capable of 2560 x 1440 but it does not offer that resolution, it has a 2560 x 1600 I have a HP EliteOne 800 G6 27 inch All-One PC that has a resolution of 2560 x 1440. Pairing two of these HP U28 HDR 28in 4K 60hz displays forced me to use the 2560 x 1600, the resolution is terrible at that setting. I am a HP fan, but this time this is a no win situation. I would welcome anyone that can tell me how to fix this problem or do I just donate these two monitors to charity. I purchased two of these, so I rated these two monitors one star because I like HP, just not these monitors. I would not recommend purchasing these unless you use their recommended 3840 x 2160 setting, it just does not work with my PC.

Rated 1 out of 5 by L. Dean Murphy from Never again. Horrid sales staff misrepresenting alleged "onsite tech" service and other false representations. This is the third HP computer I've purchased in 16 year. I won't make this mistake again.

Rated 5 out of 5 by Anonymous from Excellent Monitor Very high quality monitor. The resolution is the highest and colors and contrast perfect. Makes reading text for long periods of time less strenuous. It Is an eyes saver. The incorporated connection hub in the back makes connectivIty to external devices easy and saves you another device taking space in your desk. The fully adjustable support is well designed and I love the fact that lowering the monitor up and down is so easy. I just wished that for it will include speakers.

Rated 5 out of 5 by WeltonMedia from BIG difference from my previous monitor I'm a photographer and videographer and before I bought this I was using a generic monitor that I got on sale, no frills. I purchased this monitor because I was anticipating pairing it with an HP gaming computer but it arrived pretty quickly so I hooked it up to my laptop while I await the computer. Wow. BIG difference and very hi-def and true color. My editing quality and accuracy has improved and there are so many more menu options than a generic monitor. Definitely worth the price!

I have a motherboard which can power the screen through the USB-C upto 35w. Can I power this monitor through the UBB-C concurrently woth the display?

Asked by: Athanas
Thank you for your question! The HP U28 4K HDR Monitor draws the power for the display from the included AC adapter. The HP U28 4K HDR Monitor can then keep a laptop charged, if the laptop has the proper USB-C Power Delivery Port, via the built-in USB-C ports. The USB-C ports on the monitor deliver power to other devices.
