It is critical that you measure your monitor screen correctly to ensure proper fit of your computer filter.
Be sure to measure only the viewable screen area.

For frameless filters, the size must be exactly what you measure. For framed filters, choose the size that is nearest to your actual screen measurement or slightly larger.
Find out which 3M™ Computer Filter will work best for your work environment and screen size with the Selection Guide (PDF, 63 KB).
