More recently, there was the battle between Blu-ray and HD DVD. The main focus was computer displays, graphics cards and professional IT equipment, so more data centered markets. Nevertheless, lets quickly compare some of the specs. If the HDTV has a DisplayPort input, then a USB-C to DisplayPort adapter cable can be used to provide DisplayPort display capability. The evaluation included a statistically significant number of observers who viewed many images over four image categories including artificial engineered images, text and graphics, such as street maps or different examples of printed material, people, landscape, animals and stills. When using DisplayPort over USB-C, the USB Type-C connector becomes the single system connection point for data, full performance AV interface, and power, with such features combined or supported individually. The simple decoder (typically less than 100k gates) takes very little chip area, which minimizes implementation cost and device power use, and adds no more than one raster scan line (less than 8 usec in a 4K @ 60Hz system) to the displays throughput latency, an unnoticeable delay for interactive applications. During the development of DSC, the contributing VESA member companies performed ongoing visual tests to uncover visual compression artifacts using different image types and image motion. Website by Computer Courage. To add HDMI Alt Mode support to a device that already support DisplayPort Alt Mode, we imagine that an alternate USB-C configuration switch / signal mux would be needed in order to support the TMDS clock and data signals that are used by the HDMI signal. Some people even noticed they can lower the refresh rate to 143 and the audio starts working again. As with overall bandwidth and support for higher resolutions and refresh rates, DisplayPort has tended to offer greater support for audio sample rates, but HDMI 2.1 changed that.
