DisplayPort DualModeDie Vesa (Video Elec­tro­nics Stan­dards Asso­cia­tion) hat einen neuen Dis­play­Port-Dual­Mode Stan­dard (Ver­sion 1.1) vor­ge­stellt. Die­ser ist voll kom­pa­ti­bel mit HDMI 1.4a und ermög­licht die Über­tra­gung von 4K-Mate­rial mit einer Auf­lö­sung von 3.840 x 2.160 Bild­punk­ten und 30 Hertz.

Im Laufe des Jah­res wer­den viele neue Gra­fik­kar­ten auf den Markt kom­men, die bereits mit die­sem neuen Anschluss aus­ge­stat­tet sind. Mit einem Dis­play­Port zu HDMI-Adap­ter ist es mög­lich Moni­tor, Fern­se­her und co. mit dem PC zu ver­bin­den.

Der Dis­play­Port ist eigent­lich schon von Anfang an fähig, Ultra HD-Sin­gale mit 60hz zu ver­ar­bei­ten. Es wäre sogar mög­lich vier Full-HD Moni­tore über einen Dis­play­port lau­fen zu las­sen. Das Nadel­öhr in die­ser Kom­bi­na­tion bil­det lei­der HDMI 1.4a.

Wie dem auch sei. Mit dem neuen Dual-Dis­play­Port kann man ganz ein­fach sei­nen 4K-Moni­tor oder 4K-Fern­se­her über ein HDMI 1.4a Kabel mit der Gra­fik­karte ver­bin­den.

VESA Intro­du­ces Updated Dual-Mode Stan­dard for Hig­her Reso­lu­tion Inter­ope­ra­bi­lity with HDMI Dis­plays

Stan­dard Enables Crea­tion of New Dis­play­Port-to-HDMI Adap­tors to Sup­port Latest Gene­ra­tion of HDMI 1.4 Dis­plays

Newark, Calif., Janu­ary 31, 2013 – The Video Elec­tro­nics Stan­dards Asso­cia­tion (VESA®) today announ­ced the latest release of the Dis­play­Port Dual-Mode Stan­dard. This release sup­ports the next gene­ra­tion of Dual-Mode Dis­play­Port enab­led per­so­nal com­pu­ters and Dual-Mode Dis­play­Port cable adap­tors, expec­ted to be avail­able to con­su­mers later this year. Among several refi­ne­ments to improve inter­ope­ra­bi­lity, the updated stan­dard enables a hig­her data rate for Dis­play­Port-to-HDMI cable adap­tors, pro­vi­ding sup­port for HDMI 1.4 dis­play reso­lu­ti­ons such as 1080p 3D at 60Hz, and Ultra HD (4K x 2K) up to 30Hz frame rate, as well as 1080p with deep color.

The first Ultra HD dis­plays were intro­du­ced in 2012, but today’s Dual-Mode Dis­play­Port-to-HDMI cable adap­tors limit dis­play reso­lu­tion to 1080p,“ said Craig Wiley, senior direc­tor of mar­ke­ting at Parade Tech­no­lo­gies, and VESA Board of Direc­tors chair­man. „For a per­so­nal com­pu­ter to fully sup­port HDMI 1.4 or deep color, today a sepa­rate HDMI out­put is nee­ded. This updated Dis­play­Port Dual-Mode Stan­dard ver­sion 1.1 enables full sup­port of HDMI 1.4 video modes, and 1080p deep color, using a sim­ple cable adap­tor plug­ged into the system’s Dis­play­Port out­put. This helps to reduce the num­ber of inter­face ports nee­ded on a Per­so­nal Com­pu­ter, which is desi­ra­ble as form fac­tors shrink.“

Deve­lo­ped by VESA’s nearly 200 lea­ding indus­try mem­ber com­pa­nies, the Dis­play­Port Dual Mode Stan­dard defi­nes the requi­re­ments for Dual-Mode Dis­play­Port source devices and Dual-Mode Dis­play­Port cable adap­tors. Dis­play­Port was deve­lo­ped to pro­vide a sin­gle video inter­face that both pro­vi­des advan­ced fea­tures as well as inter­ope­ra­bi­lity with legacy dis­plays inclu­ding VGA and DVI, and HDMI. The new Dual-Mode Stan­dard is in line with this objec­tive by enab­ling the sup­port of the latest HDMI stan­dard, HDMI 1.4. In addi­tion to releasing the Dis­play­Port Dual-Mode Stan­dard Ver­sion 1.1, VESA is also releasing an updated Dis­play­Port Dual-Mode Cable Adap­tor Com­p­li­ance Test Spe­ci­fi­ca­tion, ver­sion 1.1. Con­for­mance to the updated Com­p­li­ance Test Spe­ci­fi­ca­tion, or CTS, is requi­red for using the Dis­play­Port logo with a Dual-Mode Cable Adap­tor.

A Dual-Mode Dis­play­Port source is a device, such as per­so­nal com­pu­ter, that can logi­cally out­put eit­her Dis­play­Port or TMDS (Tran­si­tio­nal-Mini­mi­zed Dif­fe­ren­tial Signa­ling) from the Dis­play­Port out­put con­nec­tor, enab­ling the sup­port of Dis­play­Port, DVI, and HDMI moni­tors. An addi­tio­nal device, spe­ci­fi­cally a Dual-Mode Dis­play­Port cable adap­tor, is requi­red to con­vert the mecha­ni­cal con­nec­tor, as well as the electri­cal aspects of the signal, to out­put that is com­pa­ti­ble with a DVI or HDMI cable and dis­play. A Dual-Mode Dis­play­Port source auto­ma­ti­cally detects the pre­sence of a plug­ged-in Dual-Mode Dis­play­Port cable adap­tor and pro­vi­des the DVI or HDMI signal, as requi­red, to sup­port the con­nec­ted DVI or HDMI moni­tor.

Prior to the updated Dual-Mode Stan­dard release, Dual-Mode cable adap­tors were limi­ted to a TMDS clock rate of 165MHz pro­vi­ding sup­port for dis­play reso­lu­ti­ons up to 1080p with 60Hz and 24 bits color. In this latest spe­ci­fi­ca­tion, a new Dual-Mode cable adap­tor con­fi­gu­ra­tion is defi­ned that enables a TMDS clock rate of up to 300MHz. While the DVI stan­dard limits TMDS clock rates up to 165MHz, the HDMI 1.4 spe­ci­fi­ca­tion allows TMDS clock rates up to 297MHz, enab­ling the sup­port of 1080p 3D at 60Hz, or Ultra HD (4K x 2K) up to 30Hz frame rate.

With the release of this new VESA spe­ci­fi­ca­tion, exis­ting adap­tors will now be refer­red to as „Type 1“ adap­tors, and the new adap­tors as „Type 2.“ A Type 2 adap­tor will be back­ward com­pa­ti­ble with an exis­ting Dual-Mode Dis­play­Port source device, but it will only sup­port up to a 165MHz TMDS clock rate unless it is used with a „Type 2 enab­led“ Dual-Mode Dis­play­Port source device. Some exis­ting sys­tems will be soft­ware updata­ble to sup­port Type 2 adap­tors. A Type-2 enab­led Dual-Mode Dis­play­Port Source devices, toge­ther with a Type 2 Dual-Mode Dis­play­Port-to-HDMI adap­tor, will enable sup­port for HDMI 1.4 dis­play modes such 1080p 3D at 60Hz, or Ultra HD (4K x 2K) up to 30Hz frame rate, as well as 1080p with deep color. Type 2 adap­tor pro­to­ty­pes are cur­rently avail­able from mul­ti­ple sup­pliers.
