Mini DisplayPort Extension Cable
Cablesson’s Mini Displayport Extension Cable is the perfect solution for extending the connection from your new Apple Cinema Display to your new generation Macbook, Macbook Pro, or Macbook Air.
The Cablesson Mini DisplayPort Extension Cable is compatible with Apple’s Mini-DisplayPort products and will be in Apples typical gloss white colour to match your Apple products. Now you can easily connect the new Apple LED Cinema Display at longer distances from your computer
Our Cablesson Mini DisplayPort Extension Cables features a female end designed to connect to the Apple LED Cinema Display, and a male end designed to connect to any new MacBook, MacBook Pro, MacBook Air, Mac Pro, iMac, or Mac Mini.
These cables will also be compatible with new Apple hardware as long as Mini-DisplayPort is Apple’s connector of choice.
These extension cables can also be used with our Cablesson Mini DisplayPort to DVI adapter, Mini DisplayPort to HDMI adapter, or DisplayPort to VGA adapter to connect to any type of display, such as a projector, HDTV, or non-Apple monitor.
Note: The Mini DisplayPort to HDMI adapter is a new improved design, this unit will carry sound for the newer models (from Mid Apri 2010) Check Apple’s site if your Mac will carry sound from Mini DisplayPort. (Enable HDMI Audio on your Mac)
Please note that this adapter is Mini DisplayPort to HDMI and will not convert from HDMI to Mini DisplayPort ( eg: to display a PS4 on an iMac with video in via Mini DP port.)
This adapter is also compatible with PCs and other equipment that have Mini DisplayPort as well as Apple Macs.
