Before you go and purchase an external monitor for your laptop, desktop, or Chromebook, evaluate how you will be working. If you don’t want to be searching for a power plug and the device you are connecting to supports USB-C with Thunderbolt 3, the Lenovo ThinkVision M14/M14t should be on your shortlist!
If you MUST have the touch-screen version of the Lenovo ThinkVision M14 (look for the M14t), be prepared to pay almost double the price (thus why I marked the price rating slightly low). However, if you go with the M14 version, this is a fabulous and extremely easy to use external monitor, provided the device you are connecting has the proper USB-C port and can send a video signal. The display is crisp and responsive and makes a great portable monitor. It folds up and can easily travel in the same bag as a laptop. And, you don’t need to search for a power plug to power it, it gets its power from the USB-C port of the connected device.
