As I mentioned in my response to Ian if you want to scale while retaining
aspect ratio you just alter the glViewport.
Monitors rarely offer this option. I know my old CRT and 6-month-old LCD don't.
I can ask the nvidia drivers to perform scaling up to the monitor resolution
for me in software while retaining aspect ratio...

You are thinking of GL_LINEAR (commonly known as bilinear) scaling, not
GL_NEAREST.
