HDMI laidai

An HDMI (High-Definition Multimedia Interface) cable is currently the most common digital interface for transmitting high-definition video and multi-channel audio signals between home audio-video devices: TVs, projectors, AV amplifiers (receivers), Blu-ray players, gaming consoles, and other sources. A single HDMI cable replaces numerous analog cables – it transmits both video, audio, and control signals with one connection.

HDMI versions – what are the differences?

HDMI 1.4 – supports up to 1080p / 4K@30Hz video resolution, ARC (Audio Return Channel) function, and 3D content. Suitable for basic home cinema systems with a Full HD TV.

HDMI 2.0 – supports 4K@60Hz, a wide HDR color gamut, up to 32 audio channels, and eARC. The recommended minimum version for modern 4K home cinema systems.

HDMI 2.0a / 2.0b – enhanced HDR10 and Dolby Vision support. An excellent choice for 4K HDR content enthusiasts.

HDMI 2.1 – the latest standard, supporting 4K@120Hz, 8K@60Hz, dynamic HDR, VRR (Variable Refresh Rate for gaming), and eARC for high-quality audio transmission. Essential for 8K TVs, PS5/Xbox Series X gaming consoles, and premium home cinema systems.

What do ARC and eARC mean?

ARC (Audio Return Channel) allows audio to be transmitted from the TV back to the amplifier or soundbar via the same HDMI cable – eliminating the need for a separate optical cable. eARC (Enhanced ARC, implemented in HDMI 2.1) supports uncompressed Dolby Atmos and DTS:X audio formats – providing maximum audio quality without any compromises.

How do expensive HDMI cables differ from budget ones?

A digital signal is either transmitted completely or not at all – so for very short distances (up to 2–3 m), a good quality budget cable with the correct standard will do the job. However, higher-end HDMI cables (e.g., AudioQuest, Proson Arctic) stand out in several important aspects: better shielding from electromagnetic interference, use higher quality copper or silver-plated conductors, have more durable braided textile or metal protective sheathing, more reliable connectors with gold plating, and a longer lifespan. For longer distances (from 5 m and more), a high-quality cable becomes critical – cheap cables may not deliver a stable 4K@60Hz or 8K signal. Optical hybrid HDMI cables (e.g., Goobay Optical Hybrid) are an ideal solution for very long distances (10–30 m) – they transmit the signal via optical fiber without any signal loss.

How to choose the right HDMI cable?

If you have a Full HD (1080p) TV – an HDMI 1.4 or 2.0 cable will suffice. If you have or plan to purchase a 4K TV – choose an HDMI 2.0 or 2.0b cable that supports 4K@60Hz and HDR. If you have an 8K TV or the latest gaming console (PS5, Xbox Series X) and want 4K@120Hz or 8K video – an HDMI 2.1 cable is essential. For distances longer than 10 m, we recommend optical hybrid HDMI cables.

Frequently Asked Questions (FAQ)

Ar HDMI laido kokybė turi reikšmės?

Tik tam tikra. Šiuolaikiniam 4K @ 60Hz signalui pakanka High Speed HDMI sertifikuoto kabelio (5–15 €). Brangūs „audiofiliniai" HDMI (100 €+) duoda minimalų ar nematomą skirtumą – signalas skaitmeninis, jis arba veikia, arba ne. Tiesiog rinkitės kokybišką, sertifikuotą gamintoją (Goobay, In-Akustik).

Kuo skiriasi HDMI 2.0 ir HDMI 2.1?

HDMI 2.0 – iki 4K @ 60 Hz, 18 Gbps pralaidumas, tinka daugumai TV ir AV imtuvų. HDMI 2.1 – iki 8K @ 60 Hz arba 4K @ 120 Hz, 48 Gbps, eARC garsui, VRR žaidimams. Naujesni TV ir žaidimų konsolės (PS5, Xbox Series X) reikalauja HDMI 2.1 pilnam funkcionalumui.

Koks maksimalus HDMI laido ilgis be signalo praradimo?

Standartiniai variniai HDMI – iki 5 m be problemų. 10 m – galima, bet reikia kokybiško kabelio (High Speed). Ilgesniems atstumams (15–50 m) naudojami aktyvūs HDMI laidai (su signalu stiprinančiu chip'u) arba HDMI per Ethernet/optinis konvertavimo sprendimas.

Kada verta rinktis optinį HDMI kabelį vietoj varinio?

Tada, kai atstumas viršija maždaug 10 m arba reikia patikimo didelės spartos signalo (4K/8K) ilgesnėje trasoje. Optinis hibridinis kabelis (pvz. Goobay 10–30 m) signalą perduoda šviesa, todėl nuostoliai per ilgį praktiškai nedidėja. Trumpiems atstumams iki 5 m optinis neduoda jokio pranašumo, todėl ten paprastai užtenka įprasto varinio kabelio.

Ką reiškia HDMI su Ethernet?

Tai funkcija (HEC), kuri leidžia keliems prietaisams dalintis interneto ryšiu per patį HDMI kabelį, nereikalaujant atskiro tinklo laido. Praktikoje ją palaiko nedaug įrenginių, todėl daugumai naudotojų ji nieko nekeičia. Tačiau „su Ethernet" pažymėti kabeliai (pvz. Goobay Premium) yra pilnos specifikacijos ir tinka įprastam vaizdo bei garso perdavimui.

Kokio HDMI kabelio reikia 8K televizoriui?

Reikia Ultra High Speed sertifikuoto kabelio, palaikančio 48 Gbps pralaidumą – tokie kaip Clicktronic 8K@60 Hz ar Proson Arctic 8K. Įprastas „High Speed" kabelis 8K vaizdo pilnai nepatempia. Renkitės kiek įmanoma trumpesnį, nes 8K signalui atstumas yra jautresnis, o jei trasa ilga – tinka optinis variantas.
