Lenovo has unveiled an interesting matching monitor alongside new models in its ThinkPad notebook series, as the ThinkVision P40w functions as both a KVM switch and a docking station for laptops via Thunderbolt 4.
With a curvature of 2500R, the ThinkVision P40w's slightly curved 37.7-inch 10-bit IPS panel in 21:9 format has a 5K Wide UHD (aka WUHD) resolution of 5,120 x 2,160 pixels. It comes factory color calibrated (Delta E <2) and covers the professional DCI-P3 color space ( 
here more on the DCI-P3 color space and its use for filmmakers) by 98%, and the sRGB color space by 99%. However, its brightness is only 300 nits and is thus below average.

ThinkVision P40w as docking station/USB hub.
If the ThinkVision P40w is connected to a notebook via Thunderbolt 4, then it also functions as a docking station/USB hub and offers a whole range of interfaces: four USB 3.2 Gen 1 Type-A ports, a Gigabit Ethernet port, an audio output, a USB 3.2 Gen 1 Type-C interface, and a Thunderbolt 4 port, which can also be used to operate another monitor via series connection.
Inputs and functionality
A Thunderbolt 4 port as well as an HDMI 2.0 and a DisplayPort 1.4 are available for the video input, and a USB 3.2 Type-B port is available for the USB hub functionality as an UpStream as an alternative to the TB4 port. In addition, the monitor can supply a connected laptop with a charging current of up to 100W via Thunderbolt 4.
Lenovo ThinkVision P40w Interfaces
With the help of its KVM switch functionality, two computers can also be used via just one mouse and keyboard on the ThinkVision P40w without having to switch cables - and via PiP or PbP (Picture-by-Picture) function, the images of both PCs can not only be displayed alternately, but also simultaneously.
For better workstation ergonomics, the ThinkVision tilts -5° to +22° as well as swivels -/+ 45° and is height-adjustable by up to 130mm - eye-saving blue light reduction is also supported. Lenovo says the ThinkVision P40w-20 is the world's first Thunderbolt 4 monitor to integrate Intel's Active Management Technology (AMT). Another new feature is the monitor's Audio Smart switch, which detects when audio devices are connected via the audio jack and then automatically activates that connection.
The Lenovo ThinkVision P40w is supposed to be launched in June 2021, the German price has not been communicated yet, but it is supposed to cost around 1,700 in the US anyway.
