XF 1.4 Responsive logo for larger screens?

Hi all,

How can I have a logo that's big enough, while not showing full size on more normal screens? I'm wondering if there's a way to have my logo NOT be pixelized when zooming in. I'd like for it to show well on larger screens, 32" to 39" at least.

Example: I have a logo that's 1200px wide, but it shows at 555px on default style settings. When I zoom in, I'd like for the quality to remain.
