Lenovo ThinkVision P40w-20 is another 40-inch ultrawide monitor with a Thunderbolt 4 connection. It is the first Thunderbolt 4 monitor to support Intel Active Management Technology (AMT), making it a perfect choice for IT administrators.

If you’re unfamiliar with AMT, it allows secure remote access to Intel vPro clients such as laptops and desktops. IT admins can use AMT to push updates to PCs, address OS problems, and other remediation remotely. It’s an important feature for commercial applications as it reduces downtimes and onsite visits.

The monitor also features handy multitasking tools such as a screen split software and a built-in KVM switch. You can split the screen for seamless multitasking, view content from two PC sources, and manage those PCs with a single keyboard and mouse.

Design

The ThinkVision P40w-20 is designed for business use. It has a clean, professional look with a black finish and thin 3-side bezels. The screen is 2500R curved to fill more of your field of view for more immersion and less distraction.

The stand provides outstanding workplace ergonomics with -5/ 22 degrees tilt, -45/ 45 degrees swivel and 130mm height adjustments. The large base is a great place to keep your keyboard and mouse when not using them to save desk space.

Image Quality

Like the LG 40WP95C, ThinkVision P40w-20 features a 39.7-inch 10-bit IPS panel with a 5120×2160 resolution and 140PPI. It produces super accurate colors with 99 percent sRGB and 98 percent coverage of the film industry standard DCI-P3.

While this monitor supports entry-level HDR, the 300nits brightness won’t give you the best HDR picture quality.

The display comes factory-calibrated with a Delta E of less than 2 for high color accuracy out of the box. Unbox and start editing right away. A calibration report is included.

The ThinkVision P40w-20 features Natural Low Blue Light technology to reduce eye fatigue when working on the monitor for long hours. The technology filters harmful blue rays while ensuring proper white balance and accurate colors.

Choosing the Best Thunderbolt 4 Monitors – The Ultimate Buying Guide

Choosing the best monitor with Thunderbolt 4 connectivity shouldn’t be hard. Here is what to look out for in a good Thunderbolt 4 monitor.

1. Number of Thunderbolt 4 Ports

You want a monitor with as many Thunderbolt 4 ports as possible as it allows you to connect many peripherals and devices to your laptop. If you have multiple Thunderbolt accessories such as external drives, eGPUs, or multiple monitors, ensure to select a monitor with more than one Thunderbolt 4 port or be ready to spend further on a Thunderbolt 4 docking station.

The LG 40WP95C comes with two Thunderbolt 4 ports, which is enough for most setups. One port to your laptop and the other for peripherals and daisy-chaining.

Having more than one Thunderbolt 4 port lets you take advantage of Thunderbolt daisy-chaining and hook multiple devices through a single Thunderbolt 4 port.

2. Thunderbolt Power Delivery

Like Thunderbolt 3, the new Thunderbolt 4 specification supports power delivery of up to 100W through the same cable. You can connect and charge your laptop at the same time, reducing cable clutter on your desk. That means you don’t need to carry your laptop’s power adapter to work.

The power delivery wattage differs across Thunderbolt 4 monitors, and so do the power requirements of laptops. You can check your laptop’s adapter rating in our complete list of Thunderbolt 4 laptops.

Most of the latest laptops come with 65W power adapters, meaning a Thunderbolt 4 monitor with 60W or more power delivery can charge most laptops in the market. Please note that a monitor with less power delivery than your laptop’s requirements will still be able to charge it, but slower than usual.

With 100W power delivery, the ThinkVision P40w-20 can charge every Thunderbolt laptop in the market while running full throttle.

3. Pixels Per Inch (PPI)

If your eyes are on a bigger monitor, you need to be careful of the monitor’s resolution. That’s because a monitor’s resolution and size determine an essential aspect of the display known as Pixels Per Inch (PPI).

High PPI is always better as it results in sharp picture quality and crisper text.

A Full HD (1920×1080) resolution on a 27-inch monitor has 82PPI, which may result in fuzzy images and blurry text. But if you upgrade to a 4K (3840×2160) resolution on the same monitor, the pixel density jumps to 163PPI, meaning sharp, detailed images with crisper text.

Pro Tip: Always aim for more than 90PPI.

Below is the recommended minimum resolution at each size for better picture quality.

Size Recommended Resolution (minimum) Pixel Density
24-inch FHD (1920×1080) 92 PPI
27-inch QHD (2560×1440) 109 PPI
32-inch QHD (2560×1440) 92 PPI
34-inch Ultrawide WQHD (3440×1440) 110 PPI
38-inch Ultrawide WQHD+ (3840×1600) 111 PPI
40-inch Ultrawide WUHD (5120×2160) 140 PPI
43-inch Ultrawide WQHD+ (3840×1200) 94 PPI
43-inch 4K UHD (3840×2160) 102 PPI
49-inch Ultrawide Dual QHD (5120×1440) 109 PPI

4. Brightness

Will you be using the monitor in bright rooms? Is HDR picture quality a priority?

If your answers to the above questions are Yeses, you need a Thunderbolt 4 monitor with higher brightness. Most desktop monitors have 250 to 350nits brightness. That’s okay for everyday use in normal lit rooms. But if you’ll use this monitor in bright rooms, ensure it has at least 400nits typical brightness.

If you want the best HDR experience, brightness is a feature you shouldn’t skimp on, ever. While some cheap monitors with 300 to 400nits can still support HDR, you’ll get the best HDR picture quality in a brighter monitor, such as 1000nits.

Other factors such as dimming technology significantly improve the HDR picture quality, but brightness plays a bigger part. If you’re buying a Thunderbolt 4 monitor for HDR, always go for 1000nits or 600nits minimum.

5. Panel Type

Monitors use different panel technologies, notably IPS, VA, and TN. The IPS panel is the best out of the three; it produces high, consistent picture quality with accurate colors and wide viewing angles. Today’s IPS panels can achieve a 1ms response time, making them great for competitive gaming.

If you want a Thunderbolt 4 monitor for photo editing and video editing, make sure it has an IPS panel. However, some cheap IPS monitors suffer from screen bleeding, something you should know before buying a budget IPS monitor.

LG uses an improved IPS technology known as Nano IPS in its 40WP95C ultrawide monitor. According to LG, Nano IPS panels produce richer colors than standard IPS displays.

VA panel trumps IPS in contrast ratio. VA panels have a higher contrast ratio out of the three panels, meaning better HDR picture quality. IPS is still the best for color accuracy and viewing angles.

We usually don’t recommend monitors with TN panels unless you’re looking for a gaming monitor. TN panels are the best for gaming as they can achieve really fast response times. But they have the worst colors and viewing angles. If you buy a TN monitor for office use, make sure to sit directly in front of it for a better picture.

6. Screen Split Software & KVM Switch

Ultrawide monitors are becoming more popular than multiple-monitor setups. Ultrawide monitors offers more screen real estate for multitasking and office productivity.

A screen split software can help you benefit more from the massive screen space. It specifically allows you to partition the screen into different layouts of multiple windows so you can open more apps side-by-side like you would in dual monitors.

On the other hand, KVM Switch is a productivity tool that allows you to view content from two different PCs and control them using a single keyboard-mouse setup. It will enable you to share the display, keyboard, and mouse with two or more computers.

The ThinkVision P40w-20 comes with a screen split software called True Split and a built-in KVM switch for seamless multitasking.

If you’re buying a Thunderbolt 4 ultrawide monitor for productivity and office use, ensure it comes with a screen split software and built-in KVM switch. Sure, you can get a third-party KVM switch or split-screen software, but that will accrue extra costs.

7. VRR Support

Thunderbolt 4 monitors are mostly designed for office use and productivity, and they rarely feature higher refresh rates. The LG 40WP95C comes with a 72Hz refresh rate, which is not ideal for competitive gaming.

If you were to play games on this monitor, there is a high chance of screen tearing. Extreme screen tearing results in a terrible gaming experience and can even make games unplayable.

One way to counter this is to select a monitor with Variable Refresh Rate (VRR) technology such as FreeSync. VRR syncs the GPU’s frame rates to the refresh rate of a monitor, resulting in a smooth and fluid gaming experience.

The LG 40WP95C combines a 72Hz refresh rate with AMD FreeSync to deliver smooth gameplay. It’s the best yet for a Thunderbolt 4 monitor.

8. Ergonomics

A Thunderbolt 4 monitor with tilt, pivot, swivel, and height adjustments is the best for office use and productivity. Ergonomic monitors let you adjust the screen to your favorite viewing position for comfortable viewing and use.

If your monitor’s height is too low, that means you have to bend your head repeatedly when using the monitor. Do that for eight hours a day, seven days a week, and you’ll soon be visiting a chiropractor.

It’s essential to buy a Thunderbolt 4 monitor with a fully-adjustable stand if you’ll spend more hours working for safety and comfort. Note that ultrawide monitors don’t support pivot adjustments because they are too wide; you can rotate them into portrait mode.

9. Connectivity – Number of Ports

If you own one of the latest laptops, you’ll quickly realize you have fewer ports than expected. Actually, most Thunderbolt laptops like the MacBook and Dell XPS only come with Type-C ports.

Getting a monitor with more ports can save you the hassle of disconnecting and connecting devices or buying dongles and docking stations. The bets Thunderbolt 4 monitors should come with extra video ports (HDMI or DisplayPort), a couple of USB-A ports, and other connectivity options like headphone jack.

The ThinkVision P40w-20 is the best Thunderbolt 4 monitor in terms of connectivity. It has 12 ports of connectivity, including two Thunderbolt 4 ports, four USB-A ports, and an extra USB-C port.
