The Apple Thunderbolt Display 27 A1407 is a 27-inch LED-backlit LCD monitor with a 2560×1440 resolution, released in October 2011. It connects via a single Thunderbolt cable that powers the display and supports daisy-chaining up to five additional devices. The unit includes a built-in 720p FaceTime HD camera, dual stereo speakers, and a 3.5mm headphone jack.
Designed as a high-end desktop companion for Mac computers, the A1407 model was Apple's first all-in-one display with Thunderbolt connectivity. It uses a IPS panel with a 16:9 aspect ratio and a 300 cd/m² brightness rating. The display supports 1 billion colors and has a contrast ratio of 1000:1. It draws power through the Thunderbolt connection, eliminating the need for a separate power adapter.
Apple discontinued the Thunderbolt Display in 2016. It remains a sought-after device among users who value integrated design and legacy compatibility with older Mac models. The A1407 model is identifiable by its aluminum frame, recessed front bezel, and the Apple logo centered below the screen.
The Apple Thunderbolt Display 27 A1407 operates using a single Thunderbolt 1.0 cable. This port handles video signal transmission, audio output, and power delivery simultaneously. When connected to a compatible Mac, the display boots automatically and configures itself to match the system's resolution and color profile.
Data passes through the Thunderbolt interface at speeds up to 10 Gbps. This allows the monitor to support external peripherals such as hard drives, additional monitors, or USB devices when daisy-chained. For example, connecting a MacBook Pro via Thunderbolt enables the display to act as a central hub for peripherals, reducing desk clutter.
Internal components include a 720p FaceTime HD camera positioned above the screen, capable of capturing video at 30 fps. The dual stereo speakers deliver balanced audio output, though they lack subwoofer support. Audio is routed through the Thunderbolt connection and can be monitored via the built-in headphone jack.
The display's core hardware includes a 27-inch IPS panel with a native resolution of 2560×1440. It supports up to 1080p video input from external sources, though the optimal experience requires a Thunderbolt-compatible Mac. The panel has a 16:9 aspect ratio and a 300 nits brightness level, suitable for office and creative work environments.
Connectivity options consist of:
Power is delivered entirely through the Thunderbolt cable. The display consumes approximately 120 watts under peak load, with a standby power draw of less than 1 watt. The monitor's weight is 25.8 pounds (11.7 kg), supported by a stable aluminum base with a tilt mechanism.
Many users assume the Apple Thunderbolt Display 27 A1407 supports HDMI or DisplayPort natively. It does not. The only video input is via Thunderbolt. Attempting to connect it with an HDMI-to-Thunderbolt adapter results in no signal unless the adapter includes a Thunderbolt controller chip and driver software.
Another misconception is that the display's built-in camera supports 1080p recording. It captures video at 720p resolution, 30 frames per second. The camera cannot record video independently; it only streams live feed during video calls through FaceTime or third-party apps.
A lesser-known fact is that the display's Thunderbolt port supports daisy-chaining up to five devices. This feature allows users to connect multiple peripherals-such as a keyboard, mouse, external drive, and secondary monitor-through a single cable. This functionality was a key selling point for professionals managing complex workstations.
In a typical home office setup, the Apple Thunderbolt Display 27 A1407 connects to a 2011 MacBook Pro via Thunderbolt. The monitor powers on automatically, displaying the desktop at 2560×1440 resolution. Four USB 2.0 ports supply power and data to a wireless keyboard, trackpad, external SSD, and a USB microphone.
During a video call, the FaceTime HD camera activates automatically. The dual speakers provide clear audio for both incoming and outgoing sound. A user can plug headphones into the 3.5mm jack to switch to private listening without interrupting the call.
For content creators, the display's 1 billion color support ensures accurate color representation. A photo editor working in Adobe Photoshop can rely on the monitor's consistent color gamut for print-ready output. The 300 nits brightness provides sufficient visibility in well-lit rooms.

While modern monitors offer higher resolutions and faster refresh rates, the Thunderbolt Display remains valued for its unified design and integration with older Mac systems. Its ability to serve as a central hub for peripherals makes it ideal for users maintaining legacy setups.
I used the Apple Thunderbolt Display 27 A1407 for two years in a freelance design workflow. It handled Illustrator and After Effects projects without lag. The daisy-chaining feature reduced cable clutter. When upgrading to a newer Mac, I repurposed it as a secondary monitor for a Windows PC using a Thunderbolt-to-DisplayPort adapter, which worked reliably.
For users seeking a compact, high-quality display with integrated peripherals, the Apple Thunderbolt Display 27 A1407 delivers consistent performance. Its design philosophy-centralized connectivity and minimal footprint-remains relevant. If you're setting up a workspace around a 2011-2015 Mac, this display offers a smooth experience.
When evaluating the Apple Thunderbolt Display 27 A1407, verify compatibility with your Mac model. The display works with Macs that have Thunderbolt ports, including the MacBook Pro (2011-2015), iMac (2012-2014), and Mac mini (2012-2014). Check Apple's official documentation for exact specifications.
Apple Thunderbolt Display 27 A1407 remains a benchmark in integrated monitor design. Its combination of visual quality, audio integration, and peripheral support sets a standard for all-in-one displays.
