The base measures 245mm (width) x 205 mm (depth) that mean the distance from the base to the edge of the screen is 290mm (screen width - base with / 2). Now we can calculate the distance from the left edge of the first base all over to the right edge of the third base. 3 bases x 245 mm = 735 mm and twice from base to base 4 x 290 mm = 1160 mm, that means you will need a table that is at least 1895 mm or 1.85m wide.

Now knowing that number I have to say that I now want to come to your home to see that :D
