HP Series 7 Pro 734pm widescreen monitor review

The importance of connectivity is such a given these days, it’s normally hard for a monitor to stand out by that metric. But the new 34-inch ultrawide HP Series 7 Pro 734pm meets that challenge handily thanks to one of the most comprehensive features sets around, putting it immediately in the running among the best business monitors we’ve tested.

Highlights include Thunderbolt 4 in and out, an additional USB-C input, a multi-port USB hub, ethernet and more. Along with the explicit connectivity of physical ports, this monitor’s 5MP pop-up webcam further adds to its connected functionality by enabling a great video conferencing experience.

The 34-inch widescreen form factor also makes for a great basic productivity proposition and the use of LG’s IPS Black panel technology puts it at the cutting edge of LCD technology when it comes to inherent contrast and colour performance.

All that said, this is a very expensive display, especially for a 34-inch ultrawide model. That makes the relatively low 3,440 by 1,440 resolution and mediocre pixel density that comes with that a little hard to stomach. Likewise, the limited HDR support included is that much more conspicuous at this price point.

HP Series 7 Pro 734pm: Design & features

• Nicely engineered
• Fantastic connectivity
• Strong productivity package

HP’s latest ultrawide productivity monitor, the HP Series 7 Pro 734pm, is very nicely put together. The stand base and vertical support are both made from robust alloy and the rest of the chassis is plastic but fairly high quality. Of course, that’s the least you’d expect at this elevated price point.

With slim bezels on three sides and a mix of black and silver surface finishes, it’s a tidy, reasonably slick device even if you probably wouldn’t pick it purely on looks. More likely to swing it in your favour is the outstanding array of connectivity. For starters, you get both Thunderbolt 4 in and out, the former with fully 100W of power delivery for keeping a laptop charged.

There’s also a further USB-C input with 65W of power delivery, plus a KVM switch, multiport USB hub and ethernet. That means you could actually share this monitor across two different laptops, keeping both charged and connecting them to a range of peripherals like keyboard, mouse and external storage, all hooked up to the display.

Oh, and you can also use those inputs to run two PCs fully in parallel thanks to split-screen capability, which includes HP’s Device Bridge 2.0 for secure file sharing. For the record, HP Device Bridge 2.0 supports both PC and Mac.

Notably, all the ports including the power connector are located within easy reach on the rear of the chassis. You don’t have to reach or peer under the lower bezel to connect any cables and the manner in which they all exit perpendicular to the rear of the chassis helps with cable management, too.

To that you can add a 5MP AI webcam. It pops out of the top bezel, which ensures full physical security and offers built-in AI functionality including face tracking and lighting adaptation.

As for the 34-inch LCD panel itself, it’s the latest IPS Black technology from LG with enhanced contrast. However, it offers a pedestrian if conventional 3,440 by 1,440 native resolution, which makes for unimpressive pixel density.

It also only meets VESA’s DisplayHDR 400 standard, which means that it’s not a true HDR display and doesn’t support local dimming. Still, there’s decent colour coverage at 98% of DCI-P3 gamut.

HP Series 7 Pro 734pm: Performance

• Punchy IPS panel
• Great webcam
• Low pixel density

The HP Series 7 Pro 734pm sports LG’s cutting-edge IPS Black panel tech. On paper it offers much higher inherent contrast than competing IPS screens at 2,000:1. Anything from 1,000:1 up to 1,300:1 is more typical for IPS.

In practice, however, it’s hard to see the difference in subjective terms. If you want really good inherent LCD contrast, VA panel tech offers up to 4,000:1 and a more noticeable upgrade in terms of black levels. Of course, OLED and its per-pixel lighting is the ultimate in contrast performance, but that’s a whole different type of display.

Either way, IPS Black does make for very accurate colours, something which HP has capitalised on with a very nice factory calibration setup in sRGB mode. You can also choose from DCI-P3 and a range of other gamut presets or go with a user-defined solution.

Strictly speaking, this isn’t a professional grade content creation monitor. But it is Pantone Validated and well enough set up for mainstream image and video editing workflows. The HDR 400 certification means there’s no local dimming and indeed limited actual HDR support. But it does ensure 400 nits peak brightness and a very punchy over experience. This is a vibrant, pleasant display to use day-to-day.

The exception to that is the mediocre pixel density. The 3,440 by 1,440 native resolution stretched over the gently curved, 21:9 aspect, 34-inch LCD panel makes for a pixel density of just 109DPI. For context, a 32-inch 4K monitor comes in at about 140DPI, a 27-inch 4K screen at 165DPI.

The result of that lower pixel density includes slightly rough looking fonts and a very slightly pixelated look and feel compared to higher density displays. This is far from unique to the HP Series 7 Pro 734pm, it’s the norm for most 34-inch ultrawide panels. But given the four-figure price tag in both the US and UK, that’s a little hard to swallow.

Still, the 120Hz refresh and reasonably zippy pixel response, the latter adjustable via four levels of pixel overdrive, certainly make for a versatile display. This isn’t a gaming monitor, for instance, but it will turn its hand to that task very well, indeed.

Another highlight is the 5MP AI-powered webcam. It’s certainly a cut above the norm for integrated webcams. It offers sharp, clear image quality and good colours. The AI face tracking also works reasonably well, even if it’s a little laggy.

Less impressive are the integrated speakers. They put out plenty of volume, but it’s a pretty thin, unpleasant din and not even a decent substitute to good laptop speakers, let alone a full desktop audio solution.

HP Series 7 Pro 734pm: Final verdict

HP is asking a lot of money for this 34-inch ultrawide display. In return you get fantastic connectivity and productivity features. There’s Thunderbolt 4 in and out, support for two laptops attached and charging at the same time, KVM functionality, split screen, file sharing, ethernet, the works.

The 34-inch widescreen form factor is also great for multi-tasking and generally getting things done, while the IPS Black panel technology makes for a great viewing experience in terms of colours and vibrancy, even if the heightened contrast compared with “conventional” IPS technology isn’t exactly obvious.

The 5MP AI webcam also performs better than most integrated webcams and adds to the overall utility and connectedness of this monitor. The one really obvious shortcoming is the 3,440 by 1,440 resolution and resulting low pixel density.

That’s very much the most common resolution for a 34-inch ultrawide panel. But at this price point, the low pixel density is pretty conspicuous, something an upgrade to the 5K2K resolution of 5,120 by 2,160 pixels would fix.

Normally, 5K2K wouldn’t be in the mix, it’s a fairly rare and premium option. But with a price tag into four figures in both the US and UK, you’d be justified to expect a premium experience. As it is, if you’re OK with the pixel density, this is otherwise a really excellent productivity display and an exceptional feature set.
