The Mini DisplayPort interface was developed by Apple. Thanks to this product, the said corporation revolutionized the smartphone market and forced all competitors to play by their own rules for several years. Many of them, by the way, tried to copy this system. The engineering side and the interface software were fully developed in Cupertino, which allowed us to create complete and complete products that are devoid of the traditional flaws of their main competitors. Only here the "insides" of these gadgets are produced by numerous foreign partners of the "apple" company, operating standards set by the relevant organizations.
Description of the mini DisplayPort to HDMI adapter
Such a device is designed to connect a monitor with an HDMI interface to personal computers or laptops manufactured by Apple or its partners with a mini-display output. The mini DisplayPort-HDMI adapter is a short cable with a socket for a high-quality video signal interface (plugged into an external monitor) and a display-port plug at the other end (connected to an image-transmitting device). The plug of such a cord must be closed with a protective cap. The throughput of a mini DisplayPort to HDMI product is determined by the video input settings of the monitor. This is due to the fact that the standard "display port" it is significantly higher.
Ban on adapter cables
HDMI Org has opposed all types of mini DisplayPort to HDMI adapters. She has the right to both prohibit and allow the sale of any devices that work with HDMI-connectors. In the case of the aforementioned cable, a very tough decision has been made. Namely: representatives of the HDMI.org group, who are responsible for the development of this specification, declared adapters such as mini DisplayPort to HDMI unlicensed. This means that all such products must be removed from sale. This situation will have a major impact on the product lines of most manufacturers around the world, including companies such as Toshiba and Apple. As a result, notifications were sent to all manufacturers with requirements to remove the mentioned adapters from sale and generally remove them from production. So today, the sale of mini DisplayPort to HDMI Adapter cables is prohibited. However, this prohibition included only products with a high-quality connector for a “daddy” type video interface, and the same devices, but with a “mum” type connector, remained. First of all, the aforementioned changes affected well-known companies, but it will be much more difficult to influence Chinese manufacturers. So, if desired, the devices in question can be purchased, for example, through auction sites.
Conclusion
When Apple presented 27-inch iMac computers with a mini DisplayPort input, many users hoped to use this device as a monitor for game consoles or Blu-ray players. After all, the quality of IPS- type matrices used in such computers with LED-backlighting is not inferior to the best LCD TVs. However, as it turned out, branded adapters do not work in the opposite direction. Therefore, the only devices with which you can use the iMac as a monitor are Apple laptops that support the mini DisplayPort interface.
