Are there major limitations of using a computer monitor as a TV if I plug another device into it (eg Apple TV) apart from the screen size?

I feel this would be a good way to go for small cheap TVs at least.

Now this looks promising. Thanks very much. I’ll give it a go.

The only advantage of Evernote over everything else is it’s scanning of the contents of PDFs. I scan all my paper documents and stored them in Evernote for easy searching. Since I moved away from Evernote (to Joplin) that’s the only thing I missed. If anyone has a suggestion for replacing this I’d be very happy.
