Good camera monitor for accurate representation?

I get a lot of recommendations for Shinobi. Wanna use it on a shoulder rig as well as stationary - will be my first monitor. I'm wondering if 5" would be enough to "see" the light to light properly. I usually do photography tethered and use a large monitor.

What monitor would you recommend? I would use it on anything from DSLR to small cine rigs like komodo.
