Does the monitor come with the microscope? Or do we need to purchase a monitor? If so do you have recommended specs for SID monitor?

The monitor is not included in the package. Any full-HD LED computer monitor with a HDMI input will be suitable. We usually recommend getting one by any well-known brand, ideally at least 24 inches large (since it’s a full-HD video you can get a monitor much larger than 24 inches if you like).
