Everything we've told you so far applies if your screen is set to high resolution and the Excel window is maximized. If not, things look different. How? Like this:
Low resolution If your screen is set to a low resolution, for example to 800 by 600 pixels, a few groups on the Ribbon will display the group name only, not the commands in the group. You will need to click the arrow on the group button to display the commands.
For example, on the View tab, the Show/Hide group has several commands to show or hide various items. With a higher resolution, you will see all the commands in the Show/Hide group. In 800 by 600 resolution, you will see the Show/Hide button, not the commands in the group.
In that case, you click the arrow on the Show/Hide group button to display the commands in the group.
The groups that display only the group name in a smaller resolution are those with less frequently used commands.
Minimized At any resolution, if you make the Excel window smaller, there is a size at which some groups will display only the group names, and you will need to click the arrow on the group button to display the commands.
Tablet PCs If you're working on a Tablet PC with a smaller screen, you'll notice that the Ribbon adjusts to show you smaller versions of tabs and groups. If you have a larger monitor, the Ribbon adjusts to show you larger versions of the tabs and groups.
