Graph Resolution (dots per inch)
Specify the default graph resolution when you save a graph:
Automatic: Save graphs at the resolution specified by your monitor settings.
Custom: Save graphs at the resolution you specify. Enter a resolution between 50 and 1000.
Troubleshooting
Disable hardware
acceleration: This setting prevents some problems that can occur when you create 3D graphs or perform dynamic 3D graph manipulation, such as rotation. If your graphs are blank and do not display any content, checking this option and then restarting Minitab might resolve your issue.
If your problem is not resolved, go to File > Options > System and select Disable hardware
acceleration.
