Hi Jose,

Thank you for purchasing our products and asking!

"why can i make all 3 monitor as one it work as a second monitor while my other two is shows as one "

I am sorry but I’m not very sure what do you mean by “a second monitor”, but if you wanted to make the additional monitor as “extended desktop”, please setup the new monitor to be “extend” from the display settings of the Control Panel.
