(1) Displayport is needed for Eyefinity, i.e., more than 2 screens.
(2) Dual link DVI adabter costs approx 100$ that converts DP to DVI.
(3) The LG screens themselves are actually displayport, as far as I'm aware so they are using a converter board for going from DVI to DP inside current displays - so in theory a display-port only (without DVI/HDMI/USB/etc) screen could be manufactured cheaper than the current lowest offerings.
The display-port standard is made in quite clever way as far as I understand it offloading the task of "driving" the display from the monitor to the gfx card maiking it possible, in theory, to do very simple displays as far as control circuitry goes.
DisplayPort has several advantages over VGA, DVI and LVDS.
* Open standard available to all VESA members free of charge and to non-members for a fee, royalty-free and extensible standard to help broad adoption
* Fewer lanes with embedded self-clock, reduced EMI with data scrambling and spread spectrum mode
* Based on a micro-packet protocol
* Allows easy expansion of the standard with multiple data types
* Flexible allocation of available bandwidth between audio and video
* Multiple video streams over single physical connection (version 1.2)
* Long-distance transmission over alternative physical media such as optical fiber (version 1.1a)
* Supports high resolution displays and multiple displays with a single cable
17.28 Gbit/s of effective video bandwidth, enough for supporting 4 simultaneous 1080p60 displays (CEA-861 timings) or 2,560 × 1,600 × 30 bit @120 Hz (CVT-R timings)[note 1]
* Designed to support internal chip-to-chip communication
* Aimed at replacing internal LVDS links to display panels with a unified link interface
* Compatible with low-voltage signaling used with sub-nanometer CMOS fabrication
* Can drive display panels directly, eliminating scaling and control circuits and allowing for cheaper and slimmer displays
* Link training with adjustable amplitude and preemphasis adapts to differing cable lengths and signal quality
* Reduced bandwidth transmission for 15 meter cable (at least 1920×1080p60, 24 bpp)
* Full bandwidth transmission for 2 meter cable
* High-speed auxiliary channel for DDC, EDID, MCCS, DPMS, HDCP, adapter identification etc. traffic
* Can be used for transmitting bi-directional USB, touch-panel data, CEC, etc.
* Self-latching connector
