Symbols not displaying correctly and matrix problem

[Alexmaster350]

Hello,

Certain symbols are not displaying correctly on the HP Prime. For example the ... symbol in large matrices instead shows a square. I have reset the calculator to factory settings and updated to the latest version yet the problem remains.

Another problem I am having is in trying to store a value for each pixel to a matrix. When I try to make a 240*320 matrix the calculator completely freezes. How then is it possible to make such a program without resorting to creating a vector for each row/column if the calculator cannot handle such large matrices?

Thanks for any help.
