LCD help

I got one of these LCD dispalys duinotech 128x64 display.

How can I find out what number the rows and columns are? I know the top is column 0, line 0. Its a 128 x 64, does that mean 128 columns and 64 rows?

That is a graphic display. It really doesn't have columns and rows. It is pixel based, 128x64 pixels. Depending on the library you use, the coordinate system used for the pixels can vary. i.e. differently libraries orient the pixels differently and some allow you to rotate the coordinate system.
