Which VNC program is it?

There’s an option in TightVNC Viewer to scale the image in the client computer, which would solve the problem.

It’s VNCviewer. Tightvnc didn’t work well on windows 7 last time I checked.

TightVNC works, but it’s not as fast, and the interface is a bit less pleasing.

Yes – TightVNC 2 resolved every issue I’d had with it on Win7.

It might not be pretty, but it works, whereas your previous VNC viewer didn’t: I’ll take functioning properly over pretty-but-broken any day!
