What are the limitations of HDMI, and why do we need alternatives?
HDMI (High-Definition Multimedia Interface) has been the standard for display connectivity for many years, but it has some limitations. One of the main limitations is its bandwidth, which can limit the resolution and refresh rate of the display. For example, HDMI 2.0 can only support up to 4K resolution at 60Hz, while HDMI 2.1 can support up to 8K resolution at 60Hz. However, with the increasing demand for higher resolutions and refresh rates, HDMI’s bandwidth limitations can become a bottleneck.
Another limitation of HDMI is its susceptibility to interference and signal degradation over long distances. This can result in a loss of signal quality, which can be frustrating for users. Additionally, HDMI is a point-to-point connection, which means that it can only connect one device to another, limiting its flexibility. These limitations have led to the development of alternative display connectivity technologies that can offer higher bandwidth, longer distances, and greater flexibility.
