Pixel Perfect x2 zoom?

Is it possible to have a project zoom x2 or x4 or x6 (etc.) on startup? For example, the layout is 320x320, but I want to keep it that size so I don't have to upscale all the tiny little sprite characters, and I want the full window to be 640x640 to give it that blocky retro look. Is there any sort of zoom feature or plugin I can use?

There are a few ways, but this has worked best for me.

Well, it worked, but that's not quite what I'm looking for, because it makes the sprites themselves blurrier on upscale. I'm hoping for some sort of zoom where there's no compression or loss on the graphics themselves.

You can scale down, but not up.... unless you create an oversized version scaled down... then up.

Eh, I think I read that has something to do with your graphics card..It's not blurry for me. If it's blurry for some and not others then I think I'm gonna need a new way of doing this as well. $#&%.

That example makes it blurrier for me, too. Some time ago, someone had the same question and I then talked about problems with scaling through the windows object. I prefer using the system's 'change display resolution'.

Here is a test cap. Please run it and see if it is blurry. (It shouldn't be)
