HP announced three new M-Series monitors at CES 2021. The new monitors, the M24f, M27f, and M32f, all feature three-sided borderless designs and are built with eye safety in mind. All three new M-series monitors should be available in March 2021 with a starting price of $139.
All three monitors are FHD and feature many of the same specifications, including a 75Hz response rate and100 percent sRGB color accuracy. Sizing is the largest difference between the monitors, though there are some other variations, such as the M32f having a response time of 7ms compared to the 5ms response time of the M24f and M27f.

Each monitor has low-blue light technology that doesn't affect their color accuracy. They also all have an Eyesafe certification. HP highlights that these are the first Eyesafe certified monitors made with recycled ocean-bound plastics. Each monitor is made with 85 percent post-consumer recycled plastic and has 100 percent recycled packaging.

How could it possibly do this? If you remove the blue wavelengths you change the colour, that is basic physics no? Is it a smart and dynamic approach whereby it only removes the blue from certain colours and not uniformly from all colours?

It'd be very difficult for me to go with 1080p at 27", let alone bigger. The pixel density is just too low. I had to upgrade my monitor a while back because I could see individual pixels sitting a normal distance from my 27" 1080p monitor. I don't mind 1080p as a UI resolution, but the density of pixels needs to be higher... but then you'd might as well use the resolution of whatever that is.
