Verdict
The Lenovo ThinkVision P34WD-40 is a great monitor for work purposes, with a rich port selection, decently detailed and deep output, smooth motion, and an understated look. The speakers here are just fine, though, and it is quite expensive against OLED rivals.

Introduction
Lenovo is best known for its business-class ThinkPad laptops, though I bet you didn’t know it also makes business-class monitors.
Enter the ThinkVision P34WD-40, a more humble 34-inch 21:9 ultrawide IPS panel with a 3440×1440 resolution and a lesser-spotted 120Hz refresh rate. It also comes with a modicum of ports, modern looks and quite a usable OSD.
For the £640/$949 asking price, it seems like a decent deal, especially given the traditionally higher cost of enterprise-grade hardware. For similar money, you can get OLED ultrawides such as the Philips Evnia 34M2C8600.
To see if this ThinkVision P34WD-40 is one of the best monitors we’ve tested, I’ve been putting it through its paces for the last couple of weeks. Let’s take a closer look.
Design
- Understated looks
- Reasonable stand adjustment
- Immense port selection
As with the brand’s ThinkPad laptops, this ThinkVision P34WD-40 monitor is quite understated in its looks, with a simple black plastic frame that’s pleasantly offset by a grey base and red accents in typical ThinkPad style. It’s a sure fit in most offices, while the flat base means it takes up less depth than V-shaped legs would, and means I can stand my Sonos Beam soundbar beneath without issue.
This is also an easy panel to assemble with a toolless construction as the stand screws in from the bottom, as a lot of other monitors do.
In addition, the ThinkVision P34WD-40 also has quite an adjustable stand with good degrees of tilt, height adjustment, and swivel, so you can get comfortable. There isn’t any portrait orientation, although for a monitor of this size and width, it may have been a bit of a challenge.
If you don’t want to use the stand, then this Lenovo monitor is VESA compatible with 100x100mm mounting. With a weight of 7.2kg, you’ll just need to make sure the arm you have can take a hefty screen like this one.
Where the ThinkVision P34WD-40 pulls ahead of a lot of its rivals is with one of the richest port selections I’ve ever seen on a monitor. The underside features an HDMI 2.1 port, plus a pair of DP ports (one of these is DP out, rather than in), a USB-C, a USB-B for powering the three-port USB-A hub and an Ethernet port. To supplement this even further, Lenovo has included a pop-out USB hub on the front with a further USB-A and two USB-Cs.
The USB-C port on the rear can provide up to 140W of power and display capabilities, making this an ideal panel to pair with modern laptops for charging and display in one cable. The other two provide 15W of power, meaning they could be used to charge a phone, for instance.
The ThinkVision P34WD-40 has a built-in KVM switch, meaning you can have multiple PCs or laptops connected to it and need one set of peripherals for controlling them all. Plus, there are picture-in-picture and picture-by-picture modes for using two devices at the same time.
Image Quality
- Decent detail and light curve for productivity tasks
- Solid brightness and contrast
- Great colour accuracy
Lenovo hasn’t opted for an OLED screen for the ThinkVision P34WD-40, but instead for an IPS Black panel that’s designed to provide much deeper blacks than a ‘standard’ IPS screen that’s fitted to lots of other monitors up and down the price ladder.
The 34-inch screen provides a lot of real estate for side-by-side multitasking, and the light 3800R curve offers more immersion for work and play without being too jarring to get used to.
This screen also benefits from a 120Hz refresh rate, which is quite rare on a work-first productivity monitor that gives it a smoother and more responsive feel than a standard 60Hz screen. There is also VRR here, although Lenovo doesn’t provide any adherence to either AMD FreeSync or Nvidia G-Sync.
Lenovo quotes this panel to get as bright as 350 nits for SDR content, with my colorimeter measuring 342.6 nits peak brightness, which is right where it should be. Granted, it means content isn’t as vibrant as on a Mini LED or an OLED screen, but it’s fine for general work.
As an IPS Black panel, I think it largely lives up to the claim of providing better depth than a standard IPS screen, with a 0.11 black level out of the box that rises to 0.18 at peak brightness. It’s customary for black levels to turn greyer as the screen gets brighter for IPS panels, and it’s nice to see the ThinkVision P34WD-40 maintain its level.
The 1890:1 contrast ratio is also close to the quoted 2000:1, and provides reasonable dynamic range, while the 6500K colour temperature is perfect.
The ThinkVision P34WD-40 is also reasonably colour-accurate, with a measured 99% of sRGB, meaning the mainstream colours required for gaming and productivity workloads are displayed virtually perfectly. As for more specialist gamuts, the 97% DCI-P3 and 87% Adobe RGB results that this Lenovo option provided are solid, and technically mean you could use this panel for more colour-sensitive workloads.
The only issue you will have to deal with in content that isn’t 21:9 by default is the blackboarding effect, where black bars appear on the sides of the screen where the output doesn’t fill the entire panel. This isn’t Lenovo’s fault, but more just a warning if you’re not used to it.
Software and Features
- Feature-rich OSD
- There are speakers!
The ThinkVision P34WD-40’s OSD is controlled via the joystick on the rear-right of the screen as you look at it, and provides a decent UI for accessing a range of settings. You can control things such as brightness, contrast and input selection, and even select the functions of USB ports, deal in things such as HDR modes, the picture-in-picture and picture-by-picture configuration and even the position of the OSD.
With this screen, you also get a pair of 3W speakers inside, which are a pleasant addition in the face of a lot of screens choosing to ditch on-board audio. That being said, they’re quite tinny, lacking bass and depth, but are here if you want them, I suppose.
Should you buy it?
You want a vast port selection
The ThinkVision P34WD-40 impresses with a large port set, with lots of USB and display inputs, plus handy extras such as a KVM switch.
You want the best definition
There isn’t anything wrong with the image quality of this Lenovo screen, although you can get an OLED ultrawide for a similar price that’ll provide much stronger blacks, contrast and general detail.
Final Thoughts
The Lenovo ThinkVision P34WD-40 is a great monitor for work purposes, with a rich port selection, decently detailed and deep output, smooth motion, and an understated look. The speakers here are just fine, though, and it is quite expensive against OLED rivals.
For instance, the Philips Evnia 34M2C8600 can be had for a similar price, and provides an OLED screen with deeper blacks, a sharper image and better dynamic range. It isn’t lacking in ports either, and has a higher refresh rate to boot. For the productivity use this screen is designed for, it fits the bill, but you can get stronger image quality.

How We Test
We use every monitor we test for at least a week. During that time, we’ll check it for ease of use and put it through its paces by using it for both everyday tasks and extended gaming sessions
We check its colours and image quality with a colorimeter to test its coverage and the display’s quality.
- Tested for a week
- Used a colorimeter to get benchmark results
