I am after a Triple monitor set up and I can't get my head around these model numbers and what the difference in them is. LG IPS236, LG IPS235, LG IPS234. It seems to me that the IPS234 is the newest of the bunch but I have no idea what the difference are in the screens themselves except for the cosmetic look. There is also an LG E2370 I was looking at as well as an Asus VS247H. What would you recommend I get?
