What you need to know

  • HP adds two new displays to its widescreen panel lineup, the Z40c G3 and Z34c G3.
  • Both the Z40c G3 and Z34c G3 are curved widescreen displays with impressive specifications for work.
  • You can expect to buy the Z40c G3 and Z34c G3 in January for $1,499 and $949, respectively.

Getting work done through each day can be improved with a larger display to cram more apps and browser windows on the same panel without needing to fetch for a laptop or connect a second monitor. This is where widescreen (and the best ultrawide monitors) come into play and HP announced the Z40c G3 and Z34c G3 at CES 2022 to achieve just that.

Starting with the Z40c G3, it's a 39.7-inch IPS monitor with a curvature of 2500R. This allows the display to wrap around you, which is easy with the 21:9 aspect ratio and an impressive resolution of 5120x2160 (WUHD). It's also got a 10-bit color depth and gamut rating of 100& with sRGB and 98% for DCI-P3.

It's not all great news, however. These impressive numbers do mean you'll be stuck with a refresh rate of just 30Hz and a response time of 14ms. This makes the Z40c G3 perfect for work but you'll need a backup option for playing your favorite games (especially competitively).

Other handy features include VESA mounting support, a Windows Hello-supporting 13MP webcam, a built-in microphone, and plenty of ports for hooking up all your accessories (and PCs). This screen will retail for $1,499 and will be available in January.

HP Z34c G3

The HP Z34c is similar to the Z40c in many ways, but it's a little smaller than the 40-inch display. The resolution is also a slight downgrade at 3440x1440 (WQHD), but it's not all bad. HP does allow for a slightly higher refresh rate of 60Hz and there's the same 10-bit color depth and solid gamut ratings.

The response time is improved and HP managed to throw in a 5MP webcam that works with Windows Hello, as well as a microphone. Like the Z40c, this screen is also designed with work in mind, allowing you to provide power to a connected laptop with an output of up to 100W.

Speaking of ports, there are plenty here, including USB-C, HDMI, DisplayPort, and USB-A. The Z34c G3 is a little more affordable, coming in at $949 and will be available in January.
