Is it possible to attach a Raspberry Pi to any of those Tabs with a HDMI port ?
How can we make out if any devise having an HDMI port is programmed for data input or output ?
A TV takes input but a Tab / Mp4 player might be only for output.
It sounds like you answered your own question. In a display device such as a TV or monitor, the HDMI port is for input. In a source device, be it a laptop, tablet, phone, Blu-ray player, Raspberry Pi or whatever, it will be output. If you're asking whether there's a marking or a difference in the physical connector, I don't think that there is. The Wikipedia page on HDMI may have more details though, as may hdmi.orgraspfly wrote:Is there any way to make out what the HDMI port in any device is made for ? Input or Output ?
TV is a display device but it is HDMI port receives input but a Tab or MP4 player also has a display but mostly their HDMI port is made for output.
