All of them has the similar features so im really confuse and also can you pls guys suggest better ips than those on the list? because i have heard that non wide monitors are better but all square types are 17" and 19" only and i cant seem to find square type higher than 20" .. is it really true that square type is better on web designing?

Update the model numbers to list the manufacturers please. (because the IPS236V is made by LG not DELL, and the only Dell touch screen is the ST2220T)

That said, the LG IPS236V is probably the only one you'd really want to use for web design. It's S-IPS whereas the others are E-IPS.

E-IPS only shows 6-bits of color data per sub pixel (It uses dithering to simulate the other two.) S-IPS is a full 8-bit persub pixel (so 24bit) panel.

What you really want is an H-IPS monitor like the dell u2410 (or hp zr2475w), but those are a bit more expensive.
