Click on the address bar and then press F11.
If you look at the top of your keyboard the should be F1-F12 if you click F11 then it will make the screen large :)
It's very easy, Right click on your monitor/desktop screen, click properties, click on Settings tab. Now select whatever screen resolution you need and click on apply. If you like it click on ok. Or select other screen resolution
There are several ways but one of the easiest and most used is to simply press and hold the f11 button for 3 seconds.And if that doesn't work you can always call someone that has to do with fixing/working on computers.I hope this helped.
