Can I use an HP monitor with a MacBook Pro with a damaged screen?

generally yes. But you need to make the leap from computer output port to display input port in at most ONE adapter, you can not "stack" adapters.

When the connection is made, you can toggle [_} Mirror displays

... by using the appropriate shortcut for your touch-bar/keyboard:

Command- BrightnessDown

Command-F1

Command fn-F1

If you want some help, please post the make&model display or a link to its specs AND

model-year and screen size of your MacBook Pro.

I use:

[_] or

[√] ... to indicate a checkbox unchecked or checked

The parameter to be toggled is "Mirror Displays", and the way you toggle it (without having to read the built-in display) is by using the appropriate keyboard shortcut -- you do not need to read the built-in display to do this.

If your MacBook Pro has the Touch Bar, you use Command-BrightnessDown on the touchpad to toggle that setting, and the external display should then light up at an appropriate resolution, with the desktop and menubar showing, mirroring the data that would normally be visible on the built-in display.

MacBook Pro 13-in 2019, two ThunderBolt-3 ports 1.4GHz 16GB with Intel Iris plus graphics 645.

Your only display-capable port is one of your two Thunderbolt-3 ports with USB-C connectors.

Depending on what inputs are on your HP display, you obtain an adapter/cable from USB-C to the display input such as DisplayPort or HDMI.

I can not find a MacBook Pro 2018 model with only two thunderbolt ports.

Are you sure that is correct?
