blurred graphics

Can you give more details on what you are doing?

I mean that resized display element is smoothed by some kind of antialiasing filter (linear interpolation).
This makes very low resolution graphics (not a photo, but retro pixel known as pixel art) blurred.
The solution would be to keep it Nearest Neighbor (known also as Crisp Edges).
Let me show difference on example image: http://asawicki.info/files/nearest_neighbor.png

You may use -VICIIfilter option to select different filter modes:

-VICIIfilter
