Hi Bryan
1
Right click your Desktop, choose Display Settings
Is Resolution and Scale set to the items marked (recommended)?
2
Right click your Desktop, do you see the control panel for your graphics card?
If so, open that and look for an Aspect Ratio setting, try each option there to see which one fits your screen better
3
On that monitor is a menu button, press that
Look for an Autofit or scaling setting to resize the image on your screen . . .
