DirectX 11 in only part of screen?

Question

I'm trying to set up a window where Direct X only participates in half of the screen.

My swap chain desc width is half screen, and my viewport width is half screen, but when I clear the render target to blue, the entire screen is blue rather than the half that I have designated for use.

Answer 1

I know that it is old question, but anyway, if someone will come here from search:

MSDN says:

Differences between Direct3D 9 and Direct3D 11/10:

Unlike Direct3D 9, the full extent of the resource view is always cleared. Viewport and scissor settings are not applied.
