mtt multitabling

[icecoldriva]

hey guys, I'm new to posting on 2p2 but I've read a lot of stuff here and figured it was a great place to find some educated answers to my questions.

I'm multitabling 16 tables (2-5 table tourneys mostly) right now on a 17" laptop by tileing 12 of the tables and then cascading 1 more in each corner. I can keep up with all the tables and am interested in adding more. I also recently tried to hook up a monitor I purchased 3 years ago that was high quality at the time. The tables were huge on this monitor and could not be minimized so it is pretty much worthless right now. I have several questions.

1) why can't I use my extra monitor? I have talked to people at best buy and circuit city and one guy said my monitor was old and another guy said my laptop needed a better graphics card which I would not be able to upgrade in my laptop withouth purchasing a new one. (its an HP nx9720 with an ATI mobility radeon x1600 graphics card)

2) what is the most tables someone has successfully multitabled?

3) what kind of set up should I consider to do more multitabling that is pretty cost effective?
