Telev\u00edzny trh je obrovsk\u00fd, no z\u00e1rove\u0148 aj ve\u013emi konkuren\u010dn\u00fd. So spusten\u00edm v\u00fdroby LED telev\u00edzorov vyvstala ot\u00e1zka, ako prezentova\u0165 telev\u00edzor lep\u0161ie ako ostatn\u00ed v\u00fdrobcovia. Zrodili sa indexy kvality, ktor\u00e9 v\u0161ak niektor\u00fdm zna\u010dk\u00e1m nepomohli. Philips, Toshiba, Sharp a Grundig teda odmietli vyr\u00e1ba\u0165 telev\u00edzory; predali obchod s telev\u00edzormi alebo poskytli licenciu na zna\u010dku in\u00e9mu v\u00fdrobcovi. Ale tento \u010dl\u00e1nok je o Samsungu.<\/p>\n\n\n\n
Index kvality obrazu PQI je pokusom spolo\u010dnosti Samsung zoradi\u0165 svoje modely telev\u00edzorov tak, aby uk\u00e1zal, ktor\u00fd je lep\u0161\u00ed. Tento trend sa za\u010dal v roku 2012, ke\u010f v\u0161etci v\u00fdrobcovia telev\u00edzorov za\u010dali pou\u017e\u00edva\u0165 ten \u010di onen index. Spo\u010diatku boli tieto indexy ozna\u010den\u00e9 ako Hertz a dosahovali obrovsk\u00e9 v\u00fd\u0161ky. V skuto\u010dnosti spolo\u010dnosti zav\u00e1dzali pou\u017e\u00edvate\u013eov a v roku 2015 tieto indexy stratili Hertz a zmenili sa na \u010d\u00edsla bez tv\u00e1re. Ak hovor\u00edme napr\u00edklad o Samsungu, index kvality sa v USA v\u00f4bec nepou\u017e\u00edva. V Eur\u00f3pe sa index kvality st\u00e1le pou\u017e\u00edva, ale len na niektor\u00fdch telev\u00edznych link\u00e1ch, a postupne sa vytr\u00e1ca.<\/p>\n\n\n\n
Spo\u010diatku spolo\u010dnos\u0165 Samsung pou\u017e\u00edvala index Clear Motion Rate a potom sa objavil PQI; to sa stalo v roku 2015, po zmiznut\u00ed PQI, ako napr\u00edklad v Spojen\u00fdch \u0161t\u00e1toch, bola obnoven\u00e1 r\u00fdchlos\u0165 pohybu. Ale v roku 2021 sa u\u017e tie\u017e nespom\u00edna Motion Rate.
D\u00f4vod je jednoduch\u00fd: ak v\u00fdrobca zverejn\u00ed index, mal by vysvetli\u0165, ako sa vypo\u010d\u00edtava a dok\u00e1za\u0165 to v praxi, ale v skuto\u010dnosti je to nemo\u017en\u00e9. Preto sk\u00f4r \u010di nesk\u00f4r v\u0161etky tieto indexy zmizn\u00fa a nahradia ich in\u00e9 pojmy, ako napr\u00edklad pohyb hry s parametrom \u00e1no.<\/p>\n\n\n\n
\u013dudia sa musia nau\u010di\u0165, ako spolo\u010dnos\u0165 Samsung vypo\u010d\u00edtava index kvality obrazu. V\u00fdsledkom je, \u017ee telev\u00edzory s rovnak\u00fdm displejom, z\u00e1kladnou doskou a procesorom bud\u00fa ma\u0165 rozdielne sk\u00f3re PQI. Treba tie\u017e poznamena\u0165, \u017ee Samsung m\u00f4\u017ee v rovnakom modeli telev\u00edzora pou\u017ei\u0165 displeje od r\u00f4znych v\u00fdrobcov a napr\u00edklad od roku 2022 u\u017e Samsung nebude vyr\u00e1ba\u0165 LED displeje pre telev\u00edzory, ke\u010f\u017ee svoju tov\u00e1re\u0148 predal \u010d\u00ednskej spolo\u010dnosti TCL. Samsung bude vyr\u00e1ba\u0165 displeje len pre nov\u00fa gener\u00e1ciu QD OLED telev\u00edzorov, ke\u010f\u017ee predajn\u00e1 prax LG uk\u00e1zala ve\u013ek\u00fd potenci\u00e1l OLED displejov.<\/p>\n\n\n\n
Ale vr\u00e1\u0165me sa k PQI; ka\u017ed\u00fd rok sa index kvality obrazu zvy\u0161uje a dynamika PQI je nasledovn\u00e1.<\/p>\n\n\n\n
2015: 100 \u2013 2 400 PQI V USA Samsung nepou\u017e\u00edva PQI, ale Motion Rate.<\/p>\n\n\n\n Ako som povedal, index PQI sa pou\u017e\u00edva len v niektor\u00fdch krajin\u00e1ch, napr\u00edklad v Eur\u00f3pe. Je nevyhnutn\u00e9 vedie\u0165, \u017ee telev\u00edzory sa vyr\u00e1baj\u00fa iba s obrazovkami s frekvenciou 60 Hz alebo 120 Hz, ale s pr\u00edchodom nov\u00fdch portov HDMI \u0161tandardu 2.1 za\u010dali telev\u00edzory podporova\u0165 obnovovacie frekvencie 144 Hz pri pou\u017eit\u00ed s grafick\u00fdmi kartami po\u010d\u00edta\u010da. Preto je mo\u017en\u00e9 PQI zladi\u0165 nasledovne: PQI a TV frekvencia.<\/p>\n\n\n\n PQI 1000 \u2013 3000 <\/strong>: Telev\u00edzory so 60 Hz displejmi, 8-bitovou farebnou h\u013abkou a technol\u00f3giou FRC PQI je index kvality zoh\u013ead\u0148uj\u00faci v\u0161etky funkcie telev\u00edzora, obrazovky a softv\u00e9ru.
