Is your screen too small or hard to see. Follow the steps below to change your resolution.
FYI: Changing your text size isn't ideal because it will cut off certain sections of portico. 

First, right-click on your desktop and click on "display settings"

Next, you are looking for a section titled "Resolution"

I would recommend you start by changing the resolution to 1360 x 768 as this has been shown to work for others. If 1360 x 768 isn't quite what you are looking for then go through the other options until you find a resolution that works for you.
Each time you choose a different resolution you will be prompted to either "Keep Changes" or "Revert." You can choose "Keep Changes" and see if that resolution works for your situation, if it doesn't simply go back and choose another.
