Correct, and neither should you probably.
I would actually never even write the abbreviation for the Tetragrammaton (the first name you have there), as it is His actual name. It's not as bad writing it in English letters, but writing it in Hebrew would be problematic.
On a computer screen, it's not as big a deal because the issue is not with actually writing it, it's with using the names carelessly. Writing the names on paper or something where it could get destroyed or defaced by being taken into the bathroom or something is the problem. The same is with saying them--saying them carelessly outside of prayer or reading the Torah is disrespectful.
And even then, we don't even say the Tetragrammaton. It's too holy of a name for us to say it. You wouldn't call your professor by his first name, so why would you speak the name of G-d like its nothing?
I'm about to turn off the computer and head to the liquor store before Shabbos. Have a good weekend, all.
