In a world where OLED monitors make all the headlines, it says something that this traditional LCD panel is one of the best new displays of 2026. The 34-inch ultrawide Philips 34B2U5900C combines a super-sharp 5K2K native resolution with excellent connectivity, including USB-C with 140W power delivery, and both 120 Hz refresh support at native resolution and a 240 Hz dual-mode at 1080p.

Allow me to introduce the new Philips 34B2U5900C. On paper, it's pretty much the ultimate non-OLED 34-inch 5K2K ultrawide productivity monitor for PCs and Macs.

If that sounds like a rather convoluted classification that amounts to faint praise, it's not meant to be. OLED monitors certainly have some clear advantages. But you simply can't get one that matches this Philips' core specification of 34-inch ultrawide with a 5K2K resolution.

That's important, because this display offers a level of pixel density and therefore text and image sharpness and clarity that no current 34-inch ultrawide OLED monitor can match.

What's more, even up against the traditional LCD competition, the Philips 34B2U5900C looks pretty special. The full 5,120 by 2,160 native resolution is supported at 120 Hz refresh and there's even a 2,560 by 1,080 alt-mode resolution at 240 Hz.

Intriguingly, this is a VA panel as opposed to the IPS type you might have expected from a 5K2K model, which is why the contrast is quoted at an impressive (for an LCD monitor) 3,000:1. Notably, the full 5K2K at 120 Hz is supported over all three video inputs: Display Port, HDMI and USB-C. While we're talking connectivity, it's positively comprehensive, with dual HDMI to accompany the aforementioned Display Port and USB-C and the latter providing an outstanding 140W thanks to supporting USB-C Power Delivery version 3.1.

A KVM switch likewise means this monitor is perfect for sharing across two machines, perhaps a PC and a Mac or a laptop and a desktop. There's plenty more in the huge feature set, including sensors for both light and user proximity, the former designed to adjust the screen's brightness to suit ambient conditions, the latter allowing this monitor to dim when you step away from your desk.

For the record, this is a Display HDR 400 certified panel, which means it's on the very lowest rung for HDR support and capability and doesn't offer local dimming, let alone the per-pixel lighting control of an OLED panel. But, again, this class of 5K2K panel simply isn't available with OLED technology. On paper, the Philips 34B2U5900C looks set to feature strongly among the best business monitors you can get.

Connectivity: HDMI 2.1 in x 2, Display Port 1.4 in x 1, USB-C with 140W PD in, USB hub with 3x USB-A and 3x USB-C, ethernet, 3.5mm headphone

Immediate impressions of the Philips 34B2U5900C are of a slightly clunky, dated old thing with a particularly thick lower bezel. An ultra-slim OLED it most clearly is not.

But it's well put together and exceptionally ergonomic. The latter attribute is thanks to the combination of a base that swivels through fully 360 degrees and clearly labelled and easily accessible ports on the rear. If you're fed up with battling with hard-to-access monitor ports, you'll love the Philips 34B2U5900C.

Speaking of connectivity, along with the dual HDMI ports, there's a Display Port socket and USB-C. The latter supports the latest PD 3.1 spec and so can deliver fully 140W of power delivery to an attached laptop. That's well up on the 96W of previous generations of USB-C single-cable connectivity and means that you use a single cable to drive this display and fully power many high-spec desktop replacement portables.

Along with a light sensor that enables the 34B2U5900C to adjust its brightness according to ambient conditions and a proximity sensor that dims the brightness when you step away from your desk, perhaps the most unusual feature in a productivity context is the dual resolution mode. By default, the 34-inch panel runs natively at 5,120 by 2,160 pixels at 120 Hz. That alone is pretty impressive for a productivity monitor with such a high resolution.

But Philips has also fitted this monitor out with a secondary dual-mode using pixel doubling to enable a resolution of 2,560 by 1,080 at 240 Hz. It's the sort of feature that you'd expect on a gaming monitor. Exactly what the use case is for productivity, content creation or day-to-day computing isn't clear. But it hardly counts as a demerit to find it included.

Finally, color coverage of 95% of the DCI-P3 gamut is reasonable, but not really the stuff of professional content creation. That said, the 34B2U5900C is at least Calman Ready for rapid automated calibration using a colorimeter.

The central appeal of the Philips 34B2U5900C is its 5K2K resolution. On this 34-inch ultrawide panel, that native resolution of 5,120 b 2,160 pixels works out to a pixel density of 163DPI.

That's exactly the same as a 27-inch 4K monitor and, indeed, this ultrawide 5K2K format is essentially a 16:9 4K 27 incher taken out to the 21:9 aspect. Add in a gentle 1500R curve, and you have a fantastic combination of widescreen ergonomics for multitasking and media immersion, plus super-sharp image quality and excellent text quality.

That applies to both Windows and Mac OS operating. What's more, among the comprehensive selection of color spaces in the 34B2U5900C's OSD menu are both s RGB and Display-P3. So, you have immediate presets to suit the native color spaces of both operating systems.

This panel looks particularly good with Mac OS. The pixel density isn't quite Retina class. But the font quality is still excellent and the ultrawide proportions allow for running as many as three application or browser windows side-by-side, a use case that obviously applies to Windows, too.

It's something of a surprise to find Philips using VA panel technology for this new 5K2K display. IPS is more typical. But this is one of the best VA screens we've seen for a long time. First, you get excellent inherent contrast for an LCD panel at 3,000:1. So, there's noticeably less light bleed than a similar IPS panel.

Even better, despite VA's reputation for poor pixel response, Philips has included three levels of configurable overdrive, the middle setting of which delivers very, very good response for this type of monitor. Motion clarity is very much in line with the 2ms quoted response performance and, in subjective terms, you're giving nothing away to the IPS competition, albeit OLED panel tech is nearly a full order of magnitude faster.

Speaking of speed, the 120 Hz refresh rate is a very welcome feature. This isn't a gaming monitor and triple-digit refresh rates are not really a particular requirement for most productivity or content creation workflows. But 120 Hz still makes for slicker and more responsive day-to-day computing.

The 240 Hz 1080p dual-mode of more questionable utility outside of gaming. Enabling it makes for clearly compromised clarity, that's for sure. But it's there for the occasional fast-paced gaming session, if that's your thing on the side.

If you're looking for limitations, there are two obvious if hardly debilitating weaknesses. First, HDR support is capped at the entry-level Display HDR 400 tier. That means a peak brightness of 400 nits and no local dimming. So, this isn't a true HDR display. But then even LCD monitors with mini-LED dimming struggle to deliver a consistent HDR performance. You need OLED and perfect per-pixel lighting for that.

The other marginal shortcoming is color coverage. You'll do better than 95% of the DCI-P3 gamut this monitor offers with an IPS panel. So, if maximising color accuracy for pro content creation workflows is critical, you may find the 34B2U5900C slightly wanting.

If you're looking for a fantastic all-rounder that combines crisp image quality with ultrawide multitasking ergonomics, great connectivity and even some surprising speed, look no further than the new Philips 34B2U5900C. It ticks so many boxes.

The 5K2K resolution on the 34-inch ultrawide panel is the main attraction. And certainly makes for both super sharp visuals and lots of desktop elbow room. In this application, the VA panel tech works really nicely too, delivering excellent contrast for an LCD monitor. Add the 120 Hz refresh at 5K2K native and surprisingly nippy pixel speed and you have a very quick and slick productivity monitor, to boot.

Then there's the excellent connectivity. The highlight is the USB-C interface with 140W capability thanks to Power Delivery 3.1 support. It means you can keep a very powerful desktop replacement laptop fully juiced, which isn't something the previous USB-C PD standards could achieve.

All told, this is comfortably one of the best monitors of 2026. It absolutely nails its high-DPI productivity brief and adds a surprising turn of speed that makes it a versatile display, even if gaming isn't exactly central to its all-business remit.

Technology and cars. Increasingly the twain shall meet. Which is handy, because Jeremy (Twitter) is addicted to both. Long-time tech journalist, former editor of i Car magazine and incumbent car guru for T3 magazine, Jeremy reckons in-car technology is about to go thermonuclear. No, not exploding cars. That would be silly. And dangerous. But rather an explosive period of unprecedented innovation. Enjoy the ride.
