Ak si si niekedy kupoval telev\u00edzor alebo monitor, pravdepodobne si narazil na \u00fadaj ako 55, 65 alebo 75 palcov. V\u00fdrobcovia pritom nikdy neuv\u00e1dzaj\u00fa \u0161\u00edrku obrazovky ako hlavn\u00fd parameter. Namiesto nej pou\u017e\u00edvaj\u00fa uhloprie\u010dku. Mnoh\u00fdch preto napadne jednoduch\u00e1 ot\u00e1zka, pre\u010do pr\u00e1ve tento rozmer?<\/p>\n

Na prv\u00fd poh\u013ead by toti\u017e v\u00e4\u010d\u0161\u00ed zmysel d\u00e1vala \u0161\u00edrka. Pr\u00e1ve t\u00fa si pri poh\u013eade na telev\u00edzor v\u0161imne\u0161 ako prv\u00fa a pr\u00e1ve pod\u013ea nej odhaduje\u0161, \u010di sa zariadenie zmest\u00ed na stol\u00edk alebo stenu, p\u00ed\u0161e Gizmodo<\/a>. Napriek tomu v\u00fdrobcovia u\u017e cel\u00e9 desa\u0165ro\u010dia pou\u017e\u00edvaj\u00fa uhloprie\u010dku a d\u00f4vod nie je n\u00e1hodn\u00fd.<\/p>\n

Keby v\u00fdrobcovia uv\u00e1dzali iba \u0161\u00edrku displeja, porovnanie jednotliv\u00fdch zariaden\u00ed by bolo ove\u013ea komplikovanej\u0161ie. D\u00f4vod spo\u010d\u00edva v pomere str\u00e1n obrazovky. Star\u0161ie telev\u00edzory pou\u017e\u00edvali form\u00e1t 4 : 3. Dne\u0161n\u00e9 telev\u00edzory v\u00e4\u010d\u0161inou vyu\u017e\u00edvaj\u00fa pomer 16 : 9, no existuj\u00fa aj ultrawide monitory s pomerom 21 : 9 alebo e\u0161te \u0161ir\u0161\u00edm zobrazen\u00edm.<\/p>\n

Ak by si porovnal dva displeje s rovnakou \u0161\u00edrkou, ich celkov\u00e1 plocha by sa mohla v\u00fdrazne l\u00ed\u0161i\u0165. Jeden by p\u00f4sobil vy\u0161\u0161\u00ed, druh\u00fd v\u00fdrazne ni\u017e\u0161\u00ed a \u0161ir\u0161\u00ed. Pr\u00e1ve preto v\u00fdrobcovia zvolili univerz\u00e1lny \u00fadaj, ktor\u00fd zah\u0155\u0148a oba rozmery naraz a t\u00fdm \u00fadajom bola pr\u00e1ve uhloprie\u010dka.<\/p>\n

Samotn\u00e1 uhloprie\u010dka s\u00edce nepovie \u00faplne v\u0161etko, no pon\u00fakne jednoduch\u00fd sp\u00f4sob, ako medzi sebou porovna\u0165 r\u00f4zne zariadenia.<\/p>\n

Ide o trad\u00edciu, ktor\u00e1 sa datuje e\u0161te k star\u00fdm telev\u00edzorom<\/p>\n

Korene dne\u0161n\u00e9ho syst\u00e9mu siahaj\u00fa hlboko do minulosti. Prv\u00e9 telev\u00edzory vyu\u017e\u00edvali obrazovky s kat\u00f3dovou trubicou, zn\u00e1mou pod skratkou CRT. Na rozdiel od dne\u0161n\u00fdch ploch\u00fdch panelov mali okr\u00fahly tvar. V\u00fdrobcovia preto prirodzene ud\u00e1vali ich priemer. Ke\u010f nesk\u00f4r pri\u0161li \u0161tvorcov\u00e9 a obd\u013a\u017enikov\u00e9 obrazovky<\/a>, priemer u\u017e ned\u00e1val zmysel. V\u00fdrobcovia v\u0161ak nechceli zavies\u0165 dva hlavn\u00e9 rozmery naraz, teda \u0161\u00edrku aj v\u00fd\u0161ku. Ako n\u00e1hradu zvolili uhloprie\u010dku, ktor\u00e1 zostala jednoduch\u00e1 na pochopenie a z\u00e1rove\u0148 zoh\u013eadnila oba rozmery displeja.<\/p>\n

Odvtedy sa tento syst\u00e9m prakticky nezmenil a pre\u017eil n\u00e1stup LCD telev\u00edzorov, LED panelov aj OLED obrazoviek.<\/p>\n

Cel\u00fd princ\u00edp uhloprie\u010dok vych\u00e1dza zo zn\u00e1mej Pytagorovej vety. Pri obd\u013a\u017eniku vznikne uhloprie\u010dka spojen\u00edm dvoch proti\u013eahl\u00fdch rohov. Jej d\u013a\u017eka z\u00e1vis\u00ed od \u0161\u00edrky aj v\u00fd\u0161ky obrazovky, tak\u017ee do jedn\u00e9ho \u010d\u00edsla zahrnie oba rozmery. To predstavuje \u010fal\u0161\u00ed d\u00f4vod, pre\u010do sa stala praktick\u00fdm univerz\u00e1lnym \u00fadajom. V\u00fdrobca nemus\u00ed pri ka\u017edom modeli zd\u013ahavo uv\u00e1dza\u0165 rozmery obrazovky v hlavnom n\u00e1zve produktu.<\/p>\n

Samozrejme, \u017ee aj marketing zohr\u00e1va svoju \u00falohu<\/p>\n

Existuje e\u0161te jeden d\u00f4vod, o ktorom sa hovor\u00ed menej. Uhloprie\u010dka predstavuje najdlh\u0161\u00ed rozmer celej obrazovky<\/a>. \u010c\u00edslo preto p\u00f4sob\u00ed v\u00e4\u010d\u0161\u00edm dojmom ne\u017e samotn\u00e1 \u0161\u00edrka alebo v\u00fd\u0161ka. Ak napr\u00edklad telev\u00edzor dostane ozna\u010denie 65 palcov, \u010d\u00edslo vyzer\u00e1 atrakt\u00edvnej\u0161ie ne\u017e \u00fadaj o pribli\u017ene 56 palcov, \u010do by predstavovalo jeho \u0161\u00edrku. Neznamen\u00e1 to, \u017ee v\u00fdrobcovia z\u00e1kazn\u00edkov zav\u00e1dzaj\u00fa. Uhloprie\u010dka zostala \u0161tandardom v celom odvetv\u00ed a ka\u017ed\u00fd v\u00fdrobca ju meria rovnak\u00fdm sp\u00f4sobom. Marketingov\u00fd efekt v\u0161ak ur\u010dite zohral svoju \u00falohu pri tom, \u017ee sa tento syst\u00e9m udr\u017eal a\u017e dodnes.<\/p>\n

\nPri k\u00fape nesta\u010d\u00ed sledova\u0165 iba palce<\/p>\n

Aj ke\u010f uhloprie\u010dka posl\u00fa\u017ei ako z\u00e1kladn\u00fd orienta\u010dn\u00fd \u00fadaj, pri v\u00fdbere telev\u00edzora alebo monitora sa oplat\u00ed pozrie\u0165 aj na \u010fal\u0161ie parametre. Rovnak\u00e1 uhloprie\u010dka toti\u017e automaticky neznamen\u00e1 rovnak\u00e9 rozmery zariadenia, ako sme u\u017e nazna\u010dili aj vy\u0161\u0161ie, r\u00f4zny pomer str\u00e1n m\u00f4\u017ee zmeni\u0165 \u0161\u00edrku aj v\u00fd\u0161ku obrazovky. Rozdiel vytvor\u00ed aj hr\u00fabka r\u00e1mikov alebo samotn\u00e1 kon\u0161trukcia telev\u00edzora. V\u00fdrobcovia preto v detailn\u00fdch technick\u00fdch \u0161pecifik\u00e1ci\u00e1ch uv\u00e1dzaj\u00fa aj presn\u00fa \u0161\u00edrku, v\u00fd\u0161ku, rozl\u00ed\u0161enie \u010di pomer str\u00e1n.\u00a0<\/p>\n

\u010eal\u0161\u00edm d\u00f4le\u017eit\u00fdm faktorom je rozl\u00ed\u0161enie, ktor\u00e9 v kombin\u00e1cii s ve\u013ekos\u0165ou obrazovky ur\u010duje hustotu pixelov (PPI). Pri v\u00e4\u010d\u0161\u00edch uhloprie\u010dkach (napr. 32 \u010di 40 palcov) u\u017e Full HD rozl\u00ed\u0161enie<\/a> nesta\u010d\u00ed, preto\u017ee obraz bude neostr\u00fd, tu je pre jemn\u00fd detail z\u00e1sadn\u00fd prechod na QHD (2K) alebo 4K.<\/p>\n

Ke\u010f si teda raz bude\u0161 vybera\u0165 nov\u00fd monitor alebo telev\u00edzor, u\u017e bude\u0161 vedie\u0165, pre\u010do sa jeho ve\u013ekos\u0165 uv\u00e1dza prim\u00e1rne cez uhloprie\u010dku. Nezabudni si ale skontrolova\u0165 aj \u010fal\u0161ie d\u00f4le\u017eit\u00e9 parametre, aby \u0165a potom doma ne\u010dakalo nepr\u00edjemn\u00e9 prekvapenie.<\/p>\n
