Zotac releases DisplayPort to dual HDMI adapterby Kristian Vättö on August 2, 2011 2:23 PM EST
Zotac has released two new products: Mini DisplayPort and DisplayPort to dual HDMI adapters. These adapters are first of their kind and simply have one (Mini) DisplayPort input and two HDMI outputs, which allows users to use one DisplayPort port for two HDMI equipped monitors.
Unfortunately the HDMI outputs are limited to 1920x1080 which indicates that this adapter might be based on older, 1.1a or earlier, DisplayPort (DP) version. A monitor with 1920x1080 resolution, 60Hz refresh rate and 24-bit color requires bandwidth of ~4.43Gb/s whereas DP 1.1a provides 10.8Gb/s, which is fine for two 1080p monitors. However, if DP 1.2 was supported, then the adapter should in theory support two monitors at 2560x1600 since they require ~8.75Gb/s each and DP 1.2 provides 21.6Gb/s.
Mac users should be pleased with an adapter like this because many Macs have only one video output, hence allowing only one external monitor. Zotac's Mini DisplayPort adapter should give Mac users an option of running two 1080p monitors on any Mac with mDP. Currently Mac users have been limited to USB video adapters and Matrox' products, which both have their limitations (USB ones are generally slow and Matrox are expensive).
Zotac has not unveiled availability details but their product page is already up so we would expect imminent availability. Suggested retail price for these adapters is $49.99, which makes them significantly cheaper than other alternatives. Zotac claims that all graphics cards are supported, including IGPs, and evidently all operating systems are supported as well.
