For VJing I dont need a very good refreshrate or color accuracy i just need to see anything
just a normal monitor wihtout anything special works for me...
Resolution is the only think i care about... and maybe brightness if i know i need to use it at a bright place.
I had some moments were everything on my screen look awsome but the projection wasnt as good and it looks crap
so allways look at the result and not at your source
