LCD touchscreens have additional layers on top of the display element itself that provide touch functionality. There are many ways to sense a user’s touch on a display, but the two most common are resistive and capacitive.

Touchscreen Display with HDMI require another channel (usually a USB port) to send touch events. For a touchscreen to be an effective input device, the user must be able to select objects accurately and avoid accidentally selecting adjacent objects.

HDMI is a digital interface that provides better video quality since all analog connections (such as component video or S-video) require no loss when converting from analog to digital. This difference is especially noticeable at higher resolutions, such as 1080p. Digital video will be sharper than component video, eliminating the softness and smearing found in component video.
