What I think you are talking about is resolution ( the size of the things on your screen) this can be done by right clicking anywhere on your desktop and selecting properties. Depending on which version of windows you have you need to look for either the setting tab or display settings and look for screen resolution. By adjusting the resolution higher it will make every thing smaller and by going lower it will make every thing bigger. Now if you actually want a bigger monitor you would have to purchase a new one.How do i change the size of my computer screen?
