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.
