I imagine you usually get questions asking for larger monitors, not smaller ones, but here goes!
Our product is small. Very small, only about 5" across and it does not vary, nor do we “gang” jobs. So a 23" monitor for soft-proofing is just silly.
I would love to find a 17 or 19 inch monitor (4:3 ratio would be preferable) for soft proofing purposes in a manufacturing environment.
