The 2015 iMac remains a beloved piece of technology for many users, thanks to its stunning Retina display and robust performance. But as newer devices take center stage, many people are looking to repurpose their iMac as an external monitor. One common question arises: What is the best video cable for a 2015 iMac monitor?
In this blog, we’ll explore the options available, troubleshoot common issues, and introduce Duet Display as a versatile alternative that can take your productivity to the next level.
Understanding the 2015 iMac’s Display Capabilities
Before diving into cable options, it’s essential to understand the Target Display Mode (TDM) feature, which allows certain iMac models to be used as external monitors. Unfortunately, this feature was limited to iMac models produced before 2014. The 2015 iMac’s stunning Retina display, while ideal for creative work, cannot be used as a monitor through traditional TDM.
This limitation leaves users looking for creative solutions—from video cables to software-based tools like Duet Display.
Best Video Cables for a 2015 iMac Monitor
If you’re set on using a video cable, here are your best options:
1. Thunderbolt 2 to HDMI Cable
- Connects the iMac’s Thunderbolt 2 port to an HDMI-supported device.
- Supports video and audio transmission.
- Best for users who want to mirror their screen on an external monitor rather than use the iMac as a monitor.
2. Mini DisplayPort to HDMI Adapter
- Allows you to connect via the Mini DisplayPort on the 2015 iMac.
- Limited to 1080p resolution when outputting video.
- Often used for presentations or extending displays.
3. USB-C to DisplayPort Cable (for connecting newer Macs)
- If connecting a modern MacBook, this cable bridges the gap between USB-C and the iMac’s DisplayPort.
- Supports high-resolution video output.
4. HDMI-to-HDMI Cables with Converters
- Useful for specific configurations involving HDMI ports.
- Requires additional adapters in some setups, which may reduce video quality.
Limitations of Video Cables:
While these options work for mirroring or extending displays, they fall short in terms of flexibility and usability for turning the 2015 iMac into a proper second monitor. That’s where Duet Display comes in.
