According to Wikipedia, the free encyclopedia, the HDMI cable has nineteen (19) pins. Also, the HDMI cable is able to carry digital sound with the video. But can it support more than just sound and video, like touch control? And, if it can, what other things can it control?
The HDMI cable goes between the monitor and the video card or onboard chipset. Even if the HDMI cable could carry signals back from a specially designed monitor with built-in touchscreen, where would they go? The video card has no use for them. And video cards do not send information from a cable to the motherboard beyond what type of monitor it is. I suppose if one had a matched video card and monitor just with that touch screen capability over HDMI cable, it could be possible. The possible is most times not economically viable. Where is the market for such items that are expensive, special, and of low volume production? And the market is already dominated by USB touchscreens.
the touch screen will be usb
this is wrong Touch screen is supported in 1.4 and 2.0 hdmi standards
