Depending on your iPad model charging port and on the external HDMI monitor/TV specs:

If you iPad has a lightning connector:--> https://www.apple.com/shop/product/MD826AM/A/lightning-digital-av-adapter?fnode=b362dbc987ff5251d36dee725a733116f26a1a5da16079da9cae0dbb771888d0b432715c6da02a8c7aa5e1362f58847c70b7f0e24277f300d36695acd9337ad895d9bed3a0cf6bbe60110dd7c69d5e5a3d45d29d94bbeb97b6a41bec050f8389d264c35a47c2f2723a675ec8f2e74109

If your iPad has an USB-C connector:--> https://www.apple.com/shop/product/MUF82AM/A/usb-c-digital-av-multiport-adapter?fnode=b362dbc987ff5251d36dee725a733116f26a1a5da16079da9cae0dbb771888d0b432715c6da02a8c7aa5e1362f58847c70b7f0e24277f300d36695acd9337ad895d9bed3a0cf6bbe60110dd7c69d5e5a3d45d29d94bbeb97b6a41bec050f8389d264c35a47c2f2723a675ec8f2e74109

If you still have a Windows PC, look at an App called Duet Display in the iOS App Store.

This may work for you, but not sure.

https://apps.apple.com/us/app/duet-display/id935754064

This app has the ability to turn your iPad into a graphics tablet-like experience.

It is a yearly or monthly subscription plan fee to get this graphics tablet feature though.

There are also, simple mirror-ing apps for Mac and PC, search online, that will simply mirror the iPad to your PC.

You would still need to draw on your iPad with Procreate, but you get s bigger image on a your Windows PC monitor

There are a few third party Mac/PC mirroring apps available online They install to your Mac or PC and use the AirPlay feature of your iPad.

These are pay apps, also.

The one I use on my older Mac ( because it does NOT support Airplay ) is called Air Server

This is a Mac/PC mobile device mirroring app

https://www.airserver.com/

Simply mirrors your iPad to your computer's screen.

You would still need to work directly from the iPad, but gets you a larger image to view, while working from your iPad.

Best of Luck to You!
