The HP Z24m G3 is a sophisticated productivity monitor geared for work from home or remote professionals. It offers an uncommon 24-inch QHD panel along with valuable accessories like its IR webcam and a 100-Watt USB-C port. It’s pricey for an office monitor, but let’s take a closer look to see if it is justified.

Design and Features
The HP Z24m G3 looks sophisticated compared to your typical business monitor thanks to its sleeker lines. The monitor has a matte black finish with a silver base, so it should aesthetically match the most popular workstations out there. The display has a bezel-free design, although it still has inner borders like most monitors.
This monitor belongs to a sub-niche, but what makes users attracted to it is its higher resolution and compact size. The monitor only needs 7.7 inches of depth, so one or two units should fit on a standard-sized desk easily. The monitor only weighs 12.6 pounds, so it’s portable and very easy to move around.
Its build quality is great even if it is lightweight, so it looks and feels like a premium display. The plastics used are thick and sturdy, and there were no cosmetic defects on any of its parts. The included stand is firm and stable so the screen won’t wobble unless the surface you put it on isn’t steady.
The HP Z24m G3 has a d-pad for its OSD instead of a joystick which is usually more convenient. However, it’s tactile and not mushy like what Samsung uses on some of its models. HP also has a Display Center app that lets you adjust some settings directly in your OS.
The stand included offers tilt, swivel, pivot, and height adjustments for your comfort and convenience. It doesn’t have VESA mounting holes, but HP included an adapter so you can mount it to a monitor arm if needed. However, the monitor is already compact, so the arm will only become necessary if you want to save space or have more than one display on deck.
One of the HP Z24m G3’s special features is its connectivity layout which lends it more flexibility compared to your average office display. It has DisplayPort 1.4, an HDMI 2.0 port, and a 100-Watt USB-C slot with DP Alt Mode. It also has a DP 1.4 Out for daisy-chaining, four USB 3.0 ports, and an RJ45 LAN port for networking.
It also has an integrated webcam with a 5MP IR sensor and built-in microphones. It’s not capable of streaming-quality clarity, but it’s good enough for video conferencing or remote work. One downside is that you have to connect the monitor via USB-C for it to work since it doesn’t have a type-B slot for data upstream.
You also get 5-watt speakers with the package to complete its conferencing suite. The pair is capable of decent sound quality and volume levels, although it doesn’t provide entertainment-grade depth or bass response. However, its equipment eliminates the need for additional equipment and messy cables if you have a USB-C laptop or computer.
Display and Performance
The HP Z24m G3 offers a 24-inch IPS panel with a 2560 x 1440 resolution, a 90Hz refresh rate, and a 5ms response time. The backlight has a 400 cd/m2 output, while the contrast is listed at 1000:1, like most IPS panels. It’s also HDR 400-certified, but we all know how limited that is in extending contrast and depth.
24-inch 1440p monitors are compact, but they are sharper than your regular displays at work or in schools. It’s great for a myriad of uses while needing less space, so it is perfect for small areas like dorms or office corners. Some might need scaling since it’s basically close to a 27-inch 4K monitor in sharpness and clarity.
The HP Z24m G3 covers 99% of the sRGB gamut and 79% of the DCI-P3 color space. Its default accuracy, which uses its sRGB mode, had an excellent deltaE average of 1.08, so it is already accurate out of the box. It falls a bit short in vibrancy compared to other premium products, but at least it is factory-calibrated and ready to go right away.
Using a colorimeter on the HP Z24m G3 reduced the average to 0.71 which is what you can expect from a prosumer variant. The downside is that you will need a colorimeter to achieve this score, and those aren’t particularly affordable. It’s also a minor improvement for most, so we can only recommend the purchase for users who are into color-critical work.
The HP Z24m G3’s brightness reached 349 cd/m2 in SDR, but it peaked at 401 cd/m2 when its HDR mode was active. The monitor’s contrast reached 981:1 at 30% brightness, so its incapable of deep blacks like OLED or VA panel types. It’s a natural limitation of the usual IPS panels, and we wish HP used IPS Black instead.
The HP Z24m G3’s panel uniformity did not have any major issues, but there were some backlight leaks on the top edge of the screen. It’s not a big issue for white or colored backgrounds, but dark scenes or if the screen is blank will reveal them. Note that this can change with every monitor made due to manufacturing tolerances, so there are better units out there.
It’s also capable of better motion clarity than other business models since it can be overclocked to 90Hz. Setting the overdrive to its 3rd level helped in giving it gaming-grade performance. However, there is still some leftover persistence, and setting the OD higher won’t help since it will add overshoot.
The HP Z24m G3 is missing FreeSync or G-Sync compatibility, which would have completed its suitability for gaming. However, its forgivable since it was not meant for gaming use since it is a business model. Input lag sits at 6ms at 90Hz, so it is great for gaming use as well.
Thoughts on the HP Z24m G3
We love the unique skillset the HP Z24m G3 offers since it basically makes the monitor a Swiss knife in this product category. It’s equipped for remote work, capable of editing-grade accuracy, and usable for gaming purposes. It is packed with features that you will not likely find on a 24-inch QHD model out there.
The one thing we dislike about it is its high price which breaches half a grand on most retailers. However, we think it’s worth the price, considering the HP Z24m G3 is capable of great performance in most user scenarios.
Pros:
- Great Color Quality
- 90Hz Maximum Refresh Rate for Better Gaming Performance
- 100-Watt USB-C and Integrated Webcam
Cons:
- Poor HDR Capabilities and Contrast
- Expensive
