In case your laptop does not show surface plots or 3-D Plots in Mathcad, what is to be done?

One of the reasons for surface plots or 3-D Plots not displayed is “Quality of Colour Reproduction”. In order to see the required plot you can enter the Control Panel of the operating system Windows Seven. After that you choose Design, Display, Display Resolution. Now you are to find and click the reference link “Extra Parameters”. In thebox which comes out immediately you choose the “Monitor” tab. The default parameter at the end of the list “Quality of Colour Reproduction” isprobably True Color (32 bits). In order to debug the system you are to choose  High Color(16 bits) parameter and press the OK or Apply button.
