HDMI vs DP (DisplayPort v1.4)
Synopsis for the newbie and some so-called techies.
HDMI (High-Definition Multimedia Interface) is a proprietary audio/video interface for transmitting uncompressed video data
and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a
compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for
analog video standards.
-------------------------------------------
DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA). The interface is
primarily used to connect a video source to a display device such as a computer monitor, though it can also be used to carry
audio, USB, and other forms of data.
(VESA) Video Electronics Standards Association designed it to replace VGA, DVI, and FPD-Link. DisplayPort is backwards
compatible with VGA, DVI and HDMI through the use of passive and active adapters.
--------------------------------------------------
So, the main difference between the two ports (HDMI vs DisplayPort):
HDMI: Television, video and other venues that do NOT require multi-display monitors.
HDMI can handle multi-displays but requires somewhat extensive mods/one port per monitor.
can sustain full bandwidth for up to 10 m (32.8 ft) of cable; comes with certification
Also, copper wire is the most common material, but HDMI signals can also be run over
CAT 5 or CAT 6 cable (for distances of up to 164 feet), over coaxial cable
(for up to 300 feet), or over fiber (for more than 328 feet),
according to HDMI Licensing LLC.
NOTE! “Active” HDMI cables have integrated circuits embedded in the cable to amplify the signal.
Active cables can be longer and thinner than passive cables
(thinner cables are less likely to fail when forced to make hard bends).
{# Security cams (ARC-Audio Return Channel)
HDMI Ethernet Channel (HEC) technology consolidates video, audio, and data streams into a single HDMI cable, and the HEC feature enables IP-based applications over HDMI and provides a bidirectional Ethernet communication at 100 Mbit/s. HEC & ARC support combined by one port/cable is also referred to as "HEAC" (HDMI Ethernet Audio Control).}
High Speed HDMI Cable with Ethernet: Supports the same resolutions as
High Speed HDMI Cable, as well as 3D, and adds support for 100-mbps ethernet.
....................................................
DisplayPort: Gamers, CAD/CAM, 3D TV, Photoshop[pers] and other graphic intense
users needing up to 4 or more monitors capable of DisplayPort 1.2 daisy-chaining, or
use of a DisplayPort MST Hub
i.e. One DisplayPort can handle up to 4 (ver.1.4) monitors with ONE CABLE.
DP Cable lengths: Passive (no chip, copper wire) Full bandwidth transmission for 3 metres (9.8 ft)
Active cable adapters; (chipped/on-board booster engine, copper wire)
NOTE! I have found 'active' cable lengths up to 50ft
w/no deprecation of signal loss (2560×1600 color depth [30 bpp @60Hz Frame rate]).
i.e. about half of the capability of DisplayPort output
Newest ver. 1.4 handles up to 8K (7680x4320 @60Hz) resolution / @ Max data rate: 29.92 Gbit/s w/DSC
... DSC (Data Stream Compression), among other things, allows DisplayPort 1.4 to drive
60Hz 8K displays and 120Hz 4K displays with HDR "deep color" over both DisplayPort and
USB Type-C cables (note that DisplayPort 1.4 doesn't add USB Type-C support;
the two have been compatible from the beginning thanks to the USB Alternate Mode spec).
DisplayPort (DP++ or dual mode DP) can emit an HDMI signal through the use of a passive adapter
connected to a port that is designed for DP++.
Addendum: DP has both...
High-bandwidth Digital Content Protection (HDCP);
i.e. digital copy protection dev by Intel Corporation
...to stop HDCP-encrypted content on unauthorized devices
DisplayPort Content Protection (DPCP) capable
i.e. 128-bit AES DisplayPort Content Protection (DPCP)

So, to sum up?
Home: I choose HDMI
Gamer: I choose DisplayPort
Corp.: I choose DisplayPort
Developer:I choose DisplayPort
Ultimately, the choice is yours.
I love FREEDOM! Don't you?
