Have you taken a look at the link I posted above, Dmitry? There you'll see that the point of the scalers (and that's why DosBOX and ScummVM have integrated them) is that it looks great on large monitors.
Both of them are emulators, and are able to scale the final picture unlike Wine. You'll get better results with VNC or a dedicated X11 server.
