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.”
