Here what I’ve found:
2x stretches to 16:9
3x looks correct
4x is stretched and positioned strangely
5x is almost correct but cuts off just a bit of the left and right sides
I think 5x looks a bit better than 3x. Can I prevent 5x from cutting off the sides?
Also 5x only works when using an HDMI cable to the monitor. It doesn’t work at all if doing OSSC -> HD Fury VGA -> monitor. Can I make VGA work on 5x?
Or maybe I should be trying to fix the stretching and bad positioning on 4x since it’s closest to the monitor’s 1600×900 native res?
