Maybe your screen resolution is too small. If so you can try adjusting as follows:
- Right-mouse click on a blank / unused area of your Desktop
- Select 'Display Settings' option
- On the 'Customise your Display' screen that pops-up, scroll down and select 'Advanced display settings'
- Click the small 'Resolution' down arrow to select a 'Resolution' to match your preference which you can experiment with. Make a note of the original setting in case you need to reset to it.
- Click 'Apply' to activate selected resolution.
