Connect a 9.7″ Retina Display (iPAD 3/4) to Your Computer via a DisplayPort Adapter

One way to connect an extra Retina (2048×1536) display to your computer is to purchase Adafruit Qualia 9.7″ DisplayPort Monitor for $224.95. But in case your budget is limited, you could combine an old iPAD 3/4 display with AbuseMark 2048×1536 LCD to DisplayPort Adapter for 3,500 JPY ($29 US). If you don’t have an old iPAD, or would rather not dismantle your “old”-but-still-useful iPAD, you could purchase LG LP097QX1-SPC1/2, LG LP097QX1-SPA1/2/V, or Samsung LTL097QL01-W01 LCD panels instead for about $80 on Amazon US (LP097QX1 / LTL097QL01). If you live in Japan, AbuseMark also ships a complete kit for 12,000 JPY.



Key features listed for the board:

  • Video Input – DisplayPort
  • Display Connector – 51-pin 0.3mm pitch FPC connector
  • STM32F103CB 32-bit Cortex M3 MCU with native USB for firmware update and power/brightness/etc control
  • Dual TI TPS61187 WLED drivers
  • Power – USB or 5V-powered (separate connector) / 1.35A total current draw.
  • Buck DC/DC converter for panel power
  • Dimmable/controllable RGB LED
  • One push button (power + overloaded function on long press)
  • Firmware upgrade over USB (DFU)
  • Dimensions – 80x40mm

If you’d like to do something a little more challenging, you could also create your own simpler RetinaDP adapter board using Eagle or KiCAD board design files make by EmerytHacks a few years ago. I’ve also been looking for Retina to HDMI adapter boards, but could not find any…

Thanks to Michaël for the tip.
