Sketch Picture Resolution

I've tried to import a high resolution picture into a sketch but Solidworks seems to downgrade the resolution.

Tried many filetypes like png, wich i prefer, jpeg, bmp etc.

Also when i import the picture in a drawing its blurry...

I like to know where in Solidworks it's possible to adjust the maximum available resolution which should be used.

Anyone ?
