To make the dartboard bigger, just right click on your desktop, go to personalization - click on Display Settings, the lower the resolution the bigger the things on screen...but just remember this will change the settings for your whole compter..you can just go back in and change them later..OR you could just click on the bottom right hand side where it says change zoom level, ( mine is at 100%) you can go as big or as small as you like..hope this has helped..

Take care
