Setting the start position of the output window.

Also, if I take words from your post here and search google for “monogame set window start position”, I get the answer in the first search result:

I’m not trying to discourage you from asking questions here, but just want to point out that quite a few answers are already out there for MonoGame. I find stuff all the time.
