Fitting for a product dubbed an “Advanced Docking Monitor,” the HP E24d G4 has a host of connectivity choices, plus comfort and convenience features tailored for corporate use. With this panel on your desk, you don’t need a separate dock for your computer, as the E24d’s generously equipped in-built USB hub lets you connect accessories galore. You can daisy-chain another monitor over a DisplayPort connection, connect to your computer with a USB Type-C cable (while supplying your PC with up to 100 watts of power), or connect two computers to the E24d in a “virtual KVM switch” configuration. You can also hook up the monitor to a LAN. These are but a few of this unique monitor’s abundant features that earn it an Editors’ Choice for high-end office-productivity displays.
All the Inputs for Corporate Use
The E24d packs a 23.8-inch IPS panel with a full HD (1,920-by-1,080-pixel) native resolution, at a standard 16:9 widescreen aspect ratio. This resolution is moderate by today’s standards, but it’s sufficient for a 24-inch display. With a 92-pixel-per-inch (ppi) pixel density, it should be more than adequate for general business use. If you want a larger screen and higher resolution, HP also offers the E27d G4 QHD Advanced Docking Monitor ($479), a 27-inch version with 2,560 by 1,440 resolution and a maximum brightness of 300 nits.
Measuring 19.5 by 21.2 by 7.5 inches (HWD) and weighing 15.1 pounds, the E24d has a matte-black frame connected to a silver stand. The screen’s top and side bezels are minimal—making it a good candidate for a multi-monitor setup—while the bottom bezel extends about 0.6 inch below the screen. Behind the top bezel is a pull-up webcam with a built-in microphone, which can be used to log in through Windows Hello face recognition (provided you disable your computer’s webcam, if any, in Device Manager), or for teleconferencing.
The E24d supports all the standard ergonomic adjustments, including height, tilt, swivel, and pivot control. If you prefer, you can mount the monitor on an arm or a wall by using the E24d’s VESA-mount bracket, with holes spaced 100mm apart, located in back of the cabinet. (The mount itself is not included.)
The notably wide range of ports is a distinguishing feature of the E24d. It has one HDMI 1.4 port, one DisplayPort 1.2 input, and one DisplayPort 1.2 output. Through the DisplayPort-out port, you can daisy-chain a second monitor. This is a feature we have seen on the Editors’ Choice Dell P2720DC, the ViewSonic TD2455, and the Mac-friendly LG UltraFine 4K Display (24MD4KL-B). In addition, a USB Type-C upstream port on the monitor supports DisplayPort-over-USB for the exchange of data or video, plus power delivery up to 100 watts, while one downstream USB-C port can provide up to 15 watts of charging power for, say, a phone. A hub of four downstream USB 3.1 ports supports fast charging of small devices with 7.5-watt delivery. You could connect external hard drives and other peripherals to this USB cluster, which in effect acts as a docking station for your computer.
There is also an RJ-45 Ethernet jack, which supports Gigabit Ethernet. We have seen Ethernet ports on several models, including the NEC MultiSync PA311D-BK, but none in the E24d’s price range. Through it, you can connect the E24d to a LAN and—when an HP laptop is connected to the monitor over a USB-C connection—enable your IT department to remotely perform other setup, administrative, and security tasks.
Supported network manageability features include PXE Boot, LAN/WLAN switching, WoL, and MAC address pass-through. The first (Preboot eXecution Environment) allows a computer to boot directly from the network. LAN/WLAN switching disables the laptop’s Wi-Fi when the monitor is connected to a LAN. Wake-on-LAN (WoL) enables a computer to be woken up remotely from a low-power state. And the MAC address pass-through function lets the laptop bypass the monitor/dock’s MAC address so it can be uniquely identified on the network with its own MAC address.
Another nifty feature is a virtual KVM switch, letting you connect two computers—one via USB-C, one via HDMI or DisplayPort—and switch between their inputs. By default, the USB-C-connected computer has precedence, but you can easily switch to the other by changing a menu setting in the onscreen display (OSD). A few other monitors, including the Dell UltraSharp 34 Curved USB-C Monitor (U3419W), have virtual KVM switches like this.
With the exception of two of the USB 3 ports and an audio-out jack (there are no built-in speakers), all the ports are downward-facing in back. Fortunately, they are easy enough to access by pivoting the monitor into portrait mode, adding or removing a device or cable, and pivoting back to landscape.
When an HP computer is connected to the E24d via USB-C, the monitor supports Single Power On, which lets you turn on both your display and laptop (even when the lid is closed), with a single button on the display. This power button (as opposed to the on/off switch, which lies in back among the ports) is on the bottom of the monitor at its right-hand edge, next to four small buttons with which you can navigate the OSD. Although the menu system is pretty standard for an OSD, the buttons—which are all but invisible beneath the bottom bezel—are not very responsive, and sometimes I had to press them several times before anything would happen.
Brightness and Color Testing
The E24d is not built for fine color work, and the results of my brightness and color coverage testing reflect that.
Its rated brightness is 250 nits (candelas per meter squared); I tested it at 209.5 nits. I measured its contrast ratio at 905:1, a bit short of its 1,000:1 rating. It covered 93.1 percent of the sRGB color gamut, the standard color space for the web and many other applications.
HP claims 72 percent coverage of NTSC, a color space developed for analog TV; I tested it at 68 percent NTSC. That said, I did a considerable amount of casual photo editing with the E24d, and I was satisfied with the results. Likewise, it proved fine for casual video watching.
A Corporate Cornucopia
At a glance, the HP E24d G4 might not seem like much out of the ordinary, with its modest native screen resolution and undistinguished color coverage. What really sets the HP E24d G4 apart from other corporate monitors is its big array of ports and supported features.
Between the pop-up webcam, its support for daisy-chaining multiple monitors, the Ethernet port, and its virtual KVM switch, the E24d’s sheer wealth of ports and business-friendly features is staggering, and the stand is nicely adjustable, too. It earns our Editors’ choice as a corporate docking monitor.
