Standardul HDMI<\/strong> se bucura de cea mai mare popularitate si ne-a usurat foarte mult conectivitatea, transmitand atat semnal video cat si audio printr-un singur cablu.<\/p>\n\n\n\n

Dar are si un mare inconvenient<\/strong> atunci cand vrei sa transmiti semnal pe distante mai lungi de 3m. In special cu cat semnalul este mai “bogat” (rezolutie\/bitrate mai mare) cu atat pierderile vor fi mai mari. Iar prin pierderi o sa vedeti flickering la greu pe ecren.<\/p>\n\n\n\n

Intre 3 si 5m este posibil sa scapati si cu un cablu conventional, mai bun, desi producatorii consacrati de cabluri vor avea doar variante de pana la 3m lungime.<\/p>\n<\/div><\/div>\n\n\n\n

\n

La distante de peste 5m este necesar sa folosim un cablu optic<\/strong> si sa avem grija de urmatoarele aspecte:<\/p>\n\n\n\n

    \n
  • este mult mai fragil si nu se poate curba sub o anumita raza;<\/li>\n\n\n\n
  • trebuie respectata directia de transmitere a semnalului, asa cum este specificata pe mufe (SOURCE -> DISPLAY<\/strong>);<\/li>\n<\/ul>\n<\/div>
