More important is that the graphic card can handle more graphic information.  As you increase your resolution & number of colors, the required memory increases.  Once you are beyond that, then the increase is used to run the graphics faster & smoother.

In the old days, the VGA RAM is used to store graphics (or text) displayed on monitor only.
But, in these days, the new VGA cards can also speed up 3D images drawing. (for many games)
So, today VGA cards need large RAM space for 3D acceleration also.

First, how much video ram do you have?
What is your resolution set to?  What is your monitor capable of?  
what is your graphics card?  Is it capable of taking extra memory?  What resolution do you want? Answer as many of these questions as you can and don't worry about the rest.  If you can answer some of these, we can probably answer your question.

Do you know how to change the resolution & color settings?  Are you running Windows 95 or 98?  This is an older computer, like early Pentium or a 486, right?
If you change the resolution to 1024x768, what happens?
