Kitted out with a 5-megapixel HDR webcam, noise-cancelling mics, and a quad speaker system, the HP Series 7 Pro 34-inch WQHD Conferencing Monitor (734pm), at $1,229 list, will pump some vroom into your Zoom calls and heat to your Google Meets. It houses a magnificent ultrawide screen with excellent image quality and adds a wealth of connectivity and other features. At a price that targets it at high-level employees, the 734pm is a good choice for managers whose schedule is packed with online meetings and who have some involvement with creative visuals. Its relatively low pixel density makes it less than ideal as a dedicated creator-centric monitor, but as a panel for incessant online collaborators, it wins an Editors' Choice award.
Design: A Gentle Curve and a Stable Base
The silvery-framed HP 734pm measures 14.3 by 32 by 4.7 inches (HWD) and weighs 25 pounds. It has a 34.1-inch screen (measured diagonally) at 3,440-by-1,440-pixel resolution—aka, ultrawide quad HD (UWQHD). With a 21:9 aspect-ratio screen, this is considered an ultrawide display, as opposed to a super ultrawide, which would have a 32:9 aspect ratio. A screen of this size and resolution has a pixel density of about 110 pixels per inch (ppi), which should be fine for casual photo or video editing, though professional creators will want a still higher pixel density.

As a panel in the IPS family, the 734pm supports vertical and horizontal viewing angles of up to 178 degrees, meaning that you can look at the screen at an extreme side angle or from above without notable degradation in color quality or brightness.
The stand feels sturdy, and the base has a large footprint. The 734pm supports height, tilt, and swivel adjustment, but not pivot adjustment between landscape and portrait mode. (Generally, ultrawide monitors this large don't have it.) The panel comes equipped with a bracket for VESA arm or wall mounting—an extra that few monitors include, even if they have the holes for VESA mounting.

The HP 734pm has a full complement of ports. You get two Thunderbolt 4 ports. One's an input, which provides up to 100W of power delivery—more than enough to power and/or charge a laptop it's connected to—and the other is a Thunderbolt-out port that provides up to 15W to charge a peripheral. Also aboard are two DisplayPort 1.4 connectors, one in and one out; the output permits the daisy-chaining of one or more additional monitors.
(Credit: Joseph Maldonado)Beyond those, a USB-C input offers up to 65 watts of power delivery, and you'll find a hub with one downstream USB-C and five USB-A ports, one of which supports 15W of charging. (One USB-A and one USB-C port are on the bottom of the monitor for easy access.) An RJ-45 Ethernet jack lets you stay connected when Wi-Fi is spotty or nonexistent, assuming you've got a wired network connection nearby.
In addition, a virtual KVM feature lets you connect and display content from two computers, and HP Device Bridge lets you share files between the two machines. A disc-like control takes the place of a row of buttons or a joystick for manipulating the panel's on-screen menus.

Although nobody's likely to buy the 734pm purely as a gaming panel, it has a couple of features that should appeal to casual gamers as well as draw the attention of game designers. The screen has a 120Hz refresh rate, and HP has included AMD FreeSync Premium. This combination should create a smoother video-watching experience, with less potential for screen tearing or artifacts.

Conferencing: One Sharp 5MP AI Webcam
The 734pm gets its conferencing cred chiefly from its pop-up 5MP Poly Studio HDR webcam, a substantial upgrade from laptop webcams, which typically sport either 0.9MP (720p) or 2MP (1080p) models. The camera, which is best controlled from the downloadable HP Display Center, includes AI functions such as auto-framing (which keeps you centered in the frame), background blur, and noise reduction.
(Credit: Joseph Maldonado)To complete the audiovisual picture, you get a pair of noise-cancelling microphones and an array of four 3W speakers with ample volume. An audio-out jack supports headphone use.

I tested the 734pm's brightness, contrast ratio, and color coverage using our standard test gear: a Klein K-10A colorimeter, a Murideo 8K SixG signal generator, and Portrait Displays' Calman Ultimate for Business calibration software.
HP rates the 734pm's luminance at 400 nits (candelas per meter squared), and in our testing, it easily cleared that, at 492 nits. The panel has a VESA DisplayHDR 400 rating. I measured its HDR luminance at 514 nits and peak HDR brightness at 562 nits.
The 734pm turned in a healthy 1,974:1 contrast ratio. HP rates its color coverage at 100% of the sRGB space and 98% of Display P3; it effectively matched both of these with 98.7% coverage of both sRGB (see the chromaticity chart below) and DCI-P3. Display P3 is Apple's implementation of DCI-P3 and is very similar to that color space.
(Credit: Portrait Displays)I also tested the 734pm's Delta E (dE), a measure of color accuracy, namely the difference between the hue of a displayed color and the color input the monitor received. The lower the dE, the more accurate the color. An average dE of below 2 indicates color accurate enough that a casual observer may be unable to distinguish any variation between the color on the screen and the intended (source) color. I measured the dE at 1.08. That's an excellent figure, particularly because the 734pm is pitched as a productivity monitor rather than a dedicated creator-centric monitor, and the company makes no specific claim about the display's dE.
In the ad-hoc, experiential part of our testing, I viewed selected video clips as well as our photo suite on the 734pm. Images were bright, with realistic-looking colors and good retention of detail in both light and dark areas.
