When your iMac's display develops issues like screen flickering, vertical lines, or overheating, you're faced with limited options. By default, iMacs don't allow you to turn off the built-in display, forcing you to either live with the visual problems or replace the entire machine.
Let's explore the challenges of a damaged iMac display and how you can effectively repurpose your machine using an external monitor.
The Challenge With Damaged iMac Displays
iMacs with display issues present several problems:
- The built-in display cannot be turned off by default
- Screen issues like flickering and vertical lines make work difficult
- Continuing to power a damaged display can worsen the problem
- Heat generation from the damaged display may cause additional stress
Common Display Issues
Many iMac users face these display problems:
- Screen flickering that worsens over time
- Vertical lines appearing across the display
- Display overheating during normal use
- Dead pixels or screen artifacts
- Uneven backlight or brightness issues
Traditional Workarounds and Their Limitations
Without proper tools, users often try reducing screen brightness to minimum when using an external monitor. However, this approach has serious drawbacks:
- The damaged display remains powered on
- Screen issues like flickering continue
- Display keeps generating heat
- Problem may worsen over time

Purpose-built tools like Mac Display Off address this limitation by allowing you to:
- Actually turn off power to the built-in display
