HP Z27K G3 4K USB-C Display Review

HP Z27K G3 4K USB-C Display Review

The HP Z27k G3 4K USB-C Display is a powerful workstation display. It boasts a UHD resolution, a supremely ergonomic stand, realistic color for web-based graphics, and a multitude of ports. It’s similar to a couple of monitors we’ve recently examined, such as the Philips 279P1 and the Dell U2720Q.

Design and Features:

The HP Z27k G3 features a sleek and refined appearance that would be at home in a high-end studio or an executive setting. Even though the gadget only requires eight inches of depth, its cabinet is very thin and excellent for mounting. Even if you type quickly, the display manages to prevent wobbling, so you won’t be dizzy. Starting with a DisplayPort 1.4 and HDMI 2.0 slot, the HP Z27k G3 boasts some connectivity options. It also contains a USB-C connector that supports DP Alt Mode and can charge laptops with up to 100 watts of electricity. It’s loaded to the gills, but it’s missing a set of built-in speakers.

4K With All the Twist:

The Z27k G3 has a 27-inch 4K screen with a native resolution of 3,840 by 2,160 pixels, often known as Ultra High Definition or 4K. It measures 21.9 by 24.1 by 8.1 inches and features a thin, strong metal frame (HWD). The display has a wide viewing range of up to 178 degrees in both vertical and horizontal viewing directions. The monitor’s height may be adjusted up to 5.9 inches, and the top of the panel can be tilted up to 20 degrees toward or away from you. This list includes the ViewSonic VP2785-4K, HP E24d G4 FHD FHD Advanced Docking Monitor, and Dell UltraSharp 27 USB-C Hub Monitor.

The HP Z27k G3 sports a 27-inch IPS panel with a resolution of 3840 x 2160, a refresh rate of 60Hz, and a response time of 5ms. With minor enhancements, it covers 100 percent of the sRGB gamut and roughly 85 percent of DCI-P3. This model doesn’t have a wide color gamut, but it is marketed as being pre-calibrated for great accuracy right out of the box. The backlight of the HP Z27k G3 reached a maximum of 295cd/m2, well below its rated standard. The contrast ratio, on the other hand, is remarkable for an IPS panel, reaching 1283:1 at 60% brightness. In fast-paced and contrasted transitions, it’s still prone to blurring, so you’ll need to use it in overdrive to achieve the best effects.

Connection Galore:

There are a lot of ports on the Z27k G3, including an HDMI port and upstream USB-C. PXE Boot, LAN/WLAN switching, and Wake-on-LAN (WoL) are all supported network manageability capabilities. WoL allows a computer to be awakened remotely from a low-power state. Compatible HP laptops can receive up to 100 watts of electricity from the monitor. The Z27k G3 is a docking-station monitor, also known as a USB hub, USB-C hub, or docking-station monitor. There are four USB 3.2 downstream connections, two of which can charge a phone or other small item at up to 7.5 watts. A hub of downstream USB 3 ports, an Ethernet jack, and DisplayPort and HDMI connectors are also included on these displays.

Fantastic Color and Contrast, Stable Brightness: We put the Z27K G3 to the test.

The HP Z27k G3 4K USB-C monitor covers up to 99 percent of the sRGB color spectrum, which is used in web-based art and a variety of other applications. The panel is also certified to cover 85 percent of the DCI-P3 color space, which is utilized in digital video. The movie’s colors were vibrant, and the contrast in both bright and gloomy situations was excellent.


  • Full-gamut sRGB coverage and realistic colors in UHD (4K) resolution 
  • The USB-C port can offer up to 100 watts of power. 
  • The stand comes with a complete set of ergonomic features. 
  • For an IPS monitor, the contrast is above average.


  • Quite costly


The HP Z27k G3 4K USB-C Display is a feature-rich productivity monitor with a full sRGB color gamut, an ergonomically pleasant stand, and a variety of connections. It performs admirably in terms of accuracy and connectivity, but similar displays are available for less.
