Czy to mo\u017cliwe, \u017ce najnowszy standard HDMI 2.1 nie oferuje w praktyce tak wiele jak to jest og\u0142aszane? W sieci pojawi\u0142y si\u0119 domniemania, \u017ce nowa technologia HDMI jest dosy\u0107 problematyczna.<\/strong><\/p>\n\n\n\n

Standard HDMI 2.1 wprowadza kilka dodatkowych funkcji, jak trzykrotnie szybsza transmisja obrazu o np. wi\u0119kszych rozdzielczo\u015bciach<\/strong>. Cho\u0107 2.0 i 2.1 wygl\u0105daj\u0105 dosy\u0107 podobnie to r\u00f3\u017cnica w parametrach jest ogromna. Administrator licencji HDMI zrezygnowa\u0142 ze standardu 2.0 i zosta\u0142 on wycofany ju\u017c w 2017 roku.<\/p>\n\n\n\n

Producenci<\/strong> telewizor\u00f3w i monitor\u00f3w powinni produkowa\u0107 sprz\u0119t zgodnie z najnowszym standardem HDMI<\/strong>, jednak jak si\u0119 okazuje – jest troch\u0119 inaczej ni\u017c powinno by\u0107. Informacje pochodz\u0105 z o\u015bwiadczenia<\/a> administratora technologii wys\u0142anego do TFT Central. Mo\u017cemy w nim przeczyta\u0107, \u017ce producenci sprz\u0119t\u00f3w powinni oznaczy\u0107 sprz\u0119t z technologi\u0105 HDMI 2.0 jako 2.1, gdy monitor lub telewizor spe\u0142nia chocia\u017c jedn\u0105 funkcj\u0119 najnowszego standard<\/strong>u.<\/p>\n\n\n\n

Ta okoliczno\u015b\u0107 mo\u017ce doprowadza\u0107 do sytuacji, w kt\u00f3rej konsument wybiera nowy sprz\u0119t opisany jako obs\u0142uguj\u0105cy HDMI 2.1, a w rzeczywisto\u015bci posiada port poprzedniego standardu<\/strong>. Portal TFT Central zauwa\u017cy\u0142, \u017ce monitor od Xiaomi 1080p 240Hz deklarowa\u0142 obs\u0142ug\u0119 HDMI 2.1, gdzie jego port specyfikacj\u0105 jest ograniczony do poprzedniej generacji. Nowy standard, jak si\u0119 okazuje, nowym standardem wcale nie jest.<\/strong><\/p>\n\n\n\n

HDMI 2.1 – paradoksalna sytuacja<\/h3>\n\n\n\n

Administrator licencji HDMI nie widzi w zaistnia\u0142ych sytuacjach nic z\u0142ego<\/strong>. Producent sprz\u0119t\u00f3w RTV jest zmuszony do wprowadzenia jednej nowej funkcji spo\u015br\u00f3d kilku, aby m\u00f3c oznaczy\u0107 port HDMI liczb\u0105 2.1. Nale\u017cy jednak zwr\u00f3ci\u0107 uwag\u0119, \u017ce najnowszy standard to nie tylko obs\u0142uga wi\u0119kszej rozdzielczo\u015bci. To tak\u017ce eARC<\/strong> (ulepszona transmisja d\u017awi\u0119ku), VRR<\/strong> (zabezpieczenie przed spadkiem ilo\u015bci klatek na sekund\u0119) czy Auto Law Latency Mode<\/strong>. To i tak nie jest wszystko, co oferuje standard 2.1. <\/p>\n\n\n\n

Sprawd\u017a te\u017c: Jak pod\u0142\u0105czy\u0107 telefon do telewizora bezprzewodowo lub po HDMI? Prosta instrukcja<\/a><\/em><\/strong><\/p>\n\n\n\n

Dosz\u0142o do kuriozalnej sytuacji, w kt\u00f3rej wiele graczy mog\u0142o, albo mo\u017ce zosta\u0107 oszukanych. Wystarczy doda\u0107 jedn\u0105 funkcj\u0119, aby producent m\u00f3g\u0142 sprzedawa\u0107 porty HDMI 2.0 w cenie nast\u0119pnej generacji<\/strong> – ma takie prawo wedle administratora portu. Wyobra\u017amy sobie sytuacj\u0119, gdzie planujemy kupi\u0107 PlayStation 5, a z nim nowy telewizor lub monitor. Zale\u017cy nam na najwy\u017cszej jako\u015bci obrazu i d\u017awi\u0119ku, a wi\u0119c wybieramy egzemplarz z HDMI 2.1. Szkoda by by\u0142o, gdyby parametrami wci\u0105\u017c oferowa\u0142 prawie to co generacja z 2017 roku. Niemo\u017cliwe, prawda? A jednak.<\/p>\n\n\n\n

Jak unikn\u0105\u0107 niepoprawnego zakupu?<\/h3>\n\n\n\n

Jedynym rozwi\u0105zaniem, w mojej opinii, b\u0119dzie dok\u0142adna analiza specyfikacji technicznej<\/strong>. Producent telewizora lub monitora musi precyzyjnie okre\u015bli\u0107 dodatkowe funkcje swojego sprz\u0119tu. Warto wi\u0119c nie ulega\u0107 potrzebie kupna nowego ekranu zaraz po przeczytaniu, \u017ce HDMI 2.1 jest na pok\u0142adzie. Producenci mog\u0105 pos\u0142ugiwa\u0107 si\u0119 t\u0105 nazw\u0105, wi\u0119c uchroni nas zdrowy rozs\u0105dek i ch\u0142odna ocena sytuacji. Wystarczy dok\u0142adnie por\u00f3wna\u0107 czy telewizor ma wszystkie funkcjonalno\u015bci przypisane do najnowszego standardu HDMI<\/strong>.  <\/p>\n","protected":false},"excerpt":{"rendered":"
