You'l have to scroll across and down in order to see them fully....lol
the pics are as follows...
the first one is a pic of all 3 mons setting side by side (the last one never falls off suprisingly enough)
the second is the properties where its all adjusted
the thrid is a screenshot of XP with 2 (1280 X 960 & 1280 X 1024)(it does not like my 3rd vid card)
and the fourth is a screenshot from winme with all 3, but much smaller resolution (i think there 1152 X 864 X2 and 1024 X 768)
