So... How classic do you want it?

[brussel]

My desktop resolution is 2560 x 1440.

If I want 4:3 with the black area off to the right would my viewport command be:
/viewport 0 0 1920 1440

I am struggling to see the benefits of using 4:3, the bit that is chopped off doesn't seem like a big deal to me.

Thank you.
