Connects display to iMac Thunderbolt
on June 11, 2012
This adapter works well and seems to be well made. Only time will tell about its lifespan, but I am using it with a desktop so it will not be subjected to periodic plugging/unplugging or cable tugging.
Its packaging and Amazon's description advertise it solely for laptops with the mini DisplayPort, but as several other reviewers have mentioned it is also for adding a second monitor to an iMac through Thunderbolt (same connector profile; combines PCI Express and DisplayPort). I use this adapter with a DVI cable between a 27" iMac and a Dell ST2421L display, and the installation was simply plug-and-play. The monitor auto-senses VGA, HDMI, and DVI. I had the DVI cable so I haven't tried HDMI, but in this two-part adapter the signal actually goes from mini DisplayPort to HDMI in the dongle and then from HDMI to DVI in the second part.
Updated 11 Oct 2012: The HDMI to DVI adapter failed within a relatively short time. The picture was all static; it was not a total signal loss and not the fault of the DVI cable (I tried another). I removed the adapter and have been running with the HDMI dongle and cable without a problem for several months. I dropped the rating to 3 stars, but a more accurate assessment would be 5 stars for HDMI and zero stars for DVI.
