The Lenovo ThinkVision P40w monitor features an inbuilt KVM and peripheral hub

The 39.7-inch 21:9 display outputs at 5120 x 2160 (in essence, a wider version of a 16:9 4k monitor) and is impressively colour accurate. It comes factory calibrated at 99% sRGB, 98% DCI-P3, and an average delta-E <2. The panel can display a 10-bit colour depth, is HDR10 compliant (300 cd/m2 brightness), and the 2500R curve helps keep the corners pointing towards the user. Lenovo says that this panel can maintain colour accuracy even when using the ‘Natural Low Blue Light’ mode but didn’t describe how this was achieved.

Video input options are Thunderbolt 4, HDMI 2.0, and DisplayPort 1.4. An identical downstream connection joins the Thunderbolt 4 input for efficient monitor daisy-chaining. The 40 Gbps bandwidth allows for a 75 Hz refresh rate (4 – 6 ms response time), along with multiple output connections such as 3.5 mm audio, 1 Gbps RJ45 Ethernet, 4 x USB3.2 Type-A, 1 USB3.2 Type-C, and thunderbolt power delivery of up to 100W.

Finally, the P40w has an eKVM which allows you to switch between two connected PCs or show their output side-by-side without the need for additional drivers. The classic examples, such as developers being able to code and test with physical hardware simultaneously, are still valid. However, a more topical example would be to screen share from a presentation PC over video conferencing while knowing there is no way to accidentally select the wrong window and show a private document from the other PC. The eKVM also supports Wake-on-LAN via S3 (sleep), S4 (hibernate), and S5 (PC off, monitor standby) modes.

The Lenovo ThinkVision P40w US release is in June 2021 at US$1,699
