    VESA anunta un nou standard: Display Port 1.3 cu suport 8K

    Video Electronics Standards Association (VESA) a anuntat definitivarea noului standard DisplayPort 1.3, rivalul cunoscutului standard HDMI urmand sa permita utilizarea ecranelor cu rezoluţii 5K sau 8K si sa ofere o latime de banda mai mare (practic avem 50% mai mult) care va imbunatati si prestatia monitoarelor UHD, compatibilitate HDCP 2.2 si suport multi-monitor imbunatatit. Astfel vom putea avea monitoare siTV-uri ce vor putea rula in 5K la 60Hz. Pentru 8K insa, ca acesta sa poata lucra la 60Hz, VESA procedeaza ca in cazul HDMI si face un subsampling de tip Y'CbCr 4:2:0 care reduce bandwith-ul (transmitand practic doar un sfert din informatiile de culoare - chroma). Important este ca atat HDMI cat si Display Port evolueaza si e bine sa tineti cont de ce tip de conexiune vor avea device-urile pe care le veti achizitiona in viitorul apropiat (atunci cand vorbim de 4K, 5K si 8K).

    VESA Releases DisplayPort™ 1.3 Standard
    DisplayPortBandwidthLatest Update to Leading Video Interface Pushes Bandwidth to 32.4 Gbits/sec

    Newark, CA (15 September 2014) – The Video Electronics Standards Association (VESA®) announced the release of the DisplayPort 1.3 audio / video (A/V) standard. An update to the widely used DisplayPort 1.2a standard, this latest version increases the maximum link bandwidth to 32.4 Gbps, with each of four lanes running at a link rate of 8.1 Gbps/lane—a 50% increase from the previous version of the DisplayPort standard. Allowing for transport overhead, DisplayPort’s 32.4 Gbps combined link rate delivers 25.92 Gbps of uncompressed video data.

    The increased bandwidth enables higher resolution monitors, including recently announced 5K monitors (with pixel resolutions of 5120 x 2880) using a single DisplayPort cable, without the use of compression. It will also enable higher resolutions when driving multiple monitors through a single connection using DisplayPort’s Multi-Stream feature, such as the use of two 4K UHD monitors, each with a pixel resolution of 3840 x 2160, when using VESA Coordinated Video Timing.DisplayPortResolutions

    DisplayPort 1.3 continues to support video conversion to VGA, DVI and HDMI. DisplayPort 1.3 adds support for HDCP 2.2 and HDMI 2.0 with CEC (Consumer Electronics Control), which enhances DisplayPort’s utility for television applications, including 4K video with copy protection. The new standard adds support for the 4:2:0 pixel structure, a video format commonly used on consumer digital television interfaces, which enables support for future 8K x 4K displays.

    DisplayPort 1.3 also enhances DisplayPort’s value for multi-function interfaces that combine data transport, A/V transport and other capabilities on a single cable. It further refines protocols that enable DisplayPort to share a single cable with other data types. With its higher 8.1 Gbps per-lane link rate, DisplayPort 1.3 can support a single UHD monitor with 60Hz refresh and 24-bit color over two lanes, while assigning the remaining two lanes to increase capacity for alternate data types, such as SuperSpeed USB data as allowed in DockPort™. DisplayPort is the A/V transport standard used by DockPort, Thunderbolt™ and other wired and wireless multi-function interface standards.

    “While becoming a mainstream video standard, DisplayPort continues to be at the cutting edge of A/V transport,” said VESA Board of Directors Chair Alan Kobayashi, Fellow & Executive R&D Management for DisplayPort Group at MegaChips Technology America. “These new enhancements to DisplayPort will facilitate both higher resolution displays, as well as easier integration of DisplayPort into multi-protocol data transports, which will satisfy consumer’s desire for simplicity and ease-of-use.”

    astia nu stiu ce sa mai scoata, noi nu avem decat 20 posturi hd din 80-100 si deja ne gandim la tv-uri UHD 4k/5k .. ca sa ce? sa ne uitam la 2-3 documentare uhd.. nu stiu nici la ora actuala cate pc-uri sunt sa poata rula ceva uhd la 60 fps-uri(ma refer la jocuri )

    @Hansel31 Ma indoiesc ca producatorii au ca target exclusiv Romania. Pe Sky Uk numarul canalelor HD a trecut de 150 deja, cateva fiind disponibile si pe Freeview (antena, semnal digital), plus un canal 3D cu filme, desene animate, dar si activitati sportive, cum ar fi seminfinalele si finala campionatului mondial. Doar pentru ca suntem noi in urma rau si ma gasesti televizoare cu tub noi in magazine(cand in Uk le-au interzis de la 01.01.2009) nu inseamna ca nu mai poate exista inovatie. Si sa nu uitam faptul ca multe posturi de televiziune romanesti nici nu au in plan macar introducerea versiunii HD, pentru ca in Romania nu gasesti 300 de posturi tv pe antena gratuit. Atat timp cat sunt platiti de operatorii de cablu, satelit, publicitate, nu mai e nevoia de a fi mai atractiv decat urmatorul post tv, sa te lupti pentru rating si cota de piata. Daca ai gasi cam toate posturile tv( mai putin cele de filme, sport, on-demand) gratuite atat pe satelit cat si antena, crede-ma ca ar aparea 50 de canale HD in 6 luni.

    Hansel31: se cheama "future proof". Asa se spunea si inainte de HD Ready... HD... FullHD, ca nu avem cu ce sa le folosim. Si iata ca acum toata lumea (sau aproape toata) are FullHD. Cat despre posturile TV din Romania, mai bine nu comentez. Cine sa investeasca in aparatura, cand mai bine baga profitul in buzunar?

    Pe principiul asta puteam ramane la arme cioplite din piatra.

    Exact. Eu chiar am prins si chestii mult mai amuzante (si probabil si tu), oameni care spuneau: la ce avem nevoie de TV Color? Oricum se emite alb negru. Si aia "invidiosi" ziceau mai tarziu ca se vede urat color, ca oamenii au fata roz/rosie/etc.

    Hehe, mi-aduc aminte de vremurile in care devenisem "future proof" punand un geam colorat in fata TV-ului Diamant-ul alb/negru (sau era un Olt... damn, nici nu mai stiu). Si am avut dreptate, in timp au facut TV-urile color! WOW, ce vizionar eram
