Welp, it looks the same for bigger, wider monitors, but AFAIK Win8 automatically limits the no. of columns when going bigger. That's why there are Win8 tweaks about the max Start Screen columns.
Also I kinda hate going multimon with the Start Screen because of the retarded edges thingy of Win8, so I use EX7forW8 to restore the start menu when going multimon.
