Currently, I use the DVI-D connector and want to try the DP connector. The latter requires a separate DP cable which I don't have it at hand. Before I throw out the money to buy DP cable I want to get some ideas about what performance differences between the two connectors in term of video quality, refresh rate, and resolution. Any inputs will be appreciated. Link to comment Share on other sites More sharing options... Awards

The advantage is a lower number of pins to achieve higher resolutions.[6]The use of data packets also allows DisplayPort to be extensible,meaning additional features can be added over time without significantchanges to the physical interface itself.[7] DisplayPort can be used to transmit audio and video simultaneously,but each one is optional and can be transmitted without the other. Thevideo signal path can have 6 to 16 bits per color channel, and the audio path can have up to 8 channels of 24-bit 192 kHz uncompressed PCM audio or can encapsulate compressed audio formats in the audio stream.[2]A bi-directional, half-duplex auxiliary channel carries devicemanagement and device control data for the Main Link, such as VESA EDID, MCCS, and DPMS standards. In addition, the interface is capable of carrying bi-directional USB signals.[8] The DisplayPort signal is not compatible with DVI or HDMI. However, Dual-Mode DisplayPorts are designed to transmit a single-link DVI or HDMI 1.2/1.4 protocol across the interface through the use of an external passive adapter that selects the desired signal and converts the electrical signaling from LVDS to TMDS. Dual-mode DisplayPorts with passive adapters do not support VGA and dual-link DVI. Those interfaces require activeadapters to convert the protocol and signal to the desired output. VGAadapters are powered by the DisplayPort connector, while dual-link DVIadapters may rely on an external power source (see compatibility with HDMI, DVI and VGA).[9] The DisplayPort connector can have 1, 2, or 4 differential data pairs(lanes) in a Main Link, each with a raw bit rate of 1.62, 2.7, or5.4 Gbit/s per lane with self-clock running at 162, 270, or 540 MHz.Data is 8b/10b encodedwhere each 8 bits of information is encoded with a 10 bit symbol. Sothe effective data rates after decoding are 1.296, 2.16, and 4.32 Gbit/sper lane (or 80% of the total).
