How to connect pi-top[4] to a monitor using an off-the-shelf microHDMI to HDMI cable
In general we recommend using pi-top 4 from a separate laptop or computer, rather than using a monitor, for which we have a variety of Connection Methods. It's even possible to access the pi-top's desktop remotely via these methods. However sometimes you may still want a direct monitor connection. This guide covers connecting with your own microHDMI to HDMI cable, rather than the pi-top Display Cable.
