Markaad dhex maran marinka TV-ga, waxaad arkaysaa noocyo badan oo ereyo-gaab ah oo loo adeegsaday sharraxaaddooda. Ultra HD , UHD , 2160p, 4K x 2K, 4K Ultra High Definition , Quad High Definition , Quad Resolution , Quad Full High Definition , QFHD , UD, HDR...^(HDR…the) liisku wuu socdaa. Lacagta dheeriga ah miyay u qalantaa xayaysiinta?

4K/UHD waxay leedahay afar jeer tirada pixels sida 1080p, markaa waa inay fiicnaataa, sax? Sax maaha. Waxa laga yaabaa inaad aragto isbeddelka tayada oo keliya haddii aad ku jirto meel fog oo daawasho ah ama haddii filimka ama sawirka uu yahay nuxur 4K ah.

4K ma hagaajin karo muuqaal kasta oo hoos yimaada 4K, markaa wax ka yar 4K ma muujin doonaan wax horumar ah. HDR (kala duwanaansho firfircooni sare leh) diiradda ma saarto ku darista pixels badan sida 4K dhigeeda ah, laakiin taa beddelkeeda waxay abuurtaa pixels ka sii wanaagsan, oo firfircoon iyadoo kor u qaadaysa isbarbardhigga iyo dhalaalka iyo bixinta midabyo kala duwan.

Jiho khaldan

Meel ay wadaagaan qaar ka mid ah soosaarayaasha aan gaarin " waayo-aragnimada HDR " ee dhabta ah ayaa macaamiisheeda marin habaabiyay iyagoo adeegsanaya weedha " HDR -karti", ama " HDR -ku habboon." Inkasta oo ay magaca HDR ku leedahay, macnaheedu maaha inay soo saari karto muuqaal tayo sare leh oo midab leh^(HDR) . TV-yadani waxay akhrin karaan oo keliya xogta badan ee HDR , taas oo ah xogta lagu dhejiyay calaamadda u sheegaysa TV-ga sida sawirka loo muujinayo.

Caqabad weyn oo haysata TV-^(TVs) yadan ayaa ah iftiinka. Telefishinada caanka ah ee leh HDR waxay garaaci karaan 500-1,000 nits (cutubka cabbira iftiinka). TV-yada^(TVs) karti u leh HDR waxay taageeraan 100-300 nits, natiijada taas oo ah midab aad u xaddidan.

Waxaa jira asal ahaan laba nooc oo tignoolajiyada HDR hadda. ^(HDR)HDR10 waxaa loo qaatay heerka aasaasiga ah ee ku dhawaad ​​TV kasta oo leh HDR . Haddii aad leedahay ciyaaryahan Ultra HD Blu-ray , markaa kani waa qaabka kaliya ee la taageeray. Doorashadaada kale waa nooca la xoojiyey ee HDR10 , oo loo yaqaan Dolby Vision .

Waa maxay Dolby Vision?

Dolby , shirkadda sidoo kale loo yaqaan Dolby Surround , waxay samaysay magac calaamad HDR 4K oo loo yaqaan Dolby Vision . Wax-soo-saarayaashu waa in qalabkooda la tijaabiyaa oo ay lacag bixiyaan si ay alaabadooda u helaan shahaado si loogu dhejiyo astaanta Dolby Vision qalabkooda. Qaabka Dolby HDR ayaa sidoo kale si weyn loogu isticmaalaa warshadaha filimada xirfadleyda ah.

Dolby Vision waxay soo saartaa tilmaamo gaar ah oo dheeraad ah oo ku saabsan waafaqid. Dolby xitaa waxay leedahay tilmaamo gaar ah oo loogu talagalay codeeynta iyo dejinta Dolby Vision HDR wax soo saarka filimada gaarka ah, TV-ga baahinta, iyo bandhigyada TV-ga. Tani waxay ka dhigaysaa mid aad uga baahi badan tignoolajiyada HDR10 .

Marka HDR10 ama Dolby Vision?

Dolby Vision TV-yadu^{(Dolby Vision TVs)} waa inay soo saaraan khibrad muuqaal ah oo xitaa ka sii wanaagsan, laakiin taa la yiraahdo, dhammaan TV-yada^(TVs) looma wada sinneen . TV-yadani^(TVs) waxay bixiyaan xog badan oo u bedeli kara goobta muuqaalka, iyaga oo ku baraya TV-ga inuu riixo isbarbardhigga ama kor u qaado midabada qaarkood. Dolby Vision waxay sameyn kartaa ilaa 12-bit qoto dheer oo midab ah oo loogu talagalay 68 bilyan oo midab oo suurtagal ah miisaanka dhalaalka, oo gaaraya ilaa 4,000 nits ama ka badan.

HDR10 waxay isticmaashaa xog badan oo go'an, taasoo siinaysa dabacsanaan yar sida TV-gaagu u soo saari karo filimaan iyo muuqaalo kala duwan. HDR10 sidoo kale waxay ku xaddidan tahay 10-bit qoto dheer oo midab ah ilaa 1.07 bilyan oo midab. Waxay ka maqnaan kartaa heerarkeeda dhalaalka marka la barbar dhigo Dolby Vision TV-yada^{(Dolby Vision TVs)} , kaliya u oggolaanaya 1,000 nits ama ka badan.

Hadda, Dolby Vision waxay u muuqataa sidii guusha macquulka ah, sax? Hagaag, ilaa hadda, ma jiro TV-ga macaamiisha ah oo xitaa awood u leh qoto dheer oo 12-bit ah. Kala duwanaanshaha Dolby Visions^{(Dolby Visions)} ayaa rajeynaya in ay saadaaliyaan alaabta mustaqbalka.

Xitaa shuruudaha iftiinka, qaababka Dolby iyo HDR10 labadaba waa la qalloocin karaa. Tusaale ahaan tan waa OLEDs^(OLED) oo aan gaari karin heerarka dhalaalka LCD laakiin waxay bixin karaan khibrad sare marka la eego heerarka iftiinka hoose. Si kastaba ha noqotee, labada TV-yadu^(TVs) waxay u qalmaan HDR10 iyo Dolby visions ku habboon.

U gudub barta!

Markaa, Haddii^(Whether) aad rabto aqoonta iyo macluumaadka gaarka ah ee labadan nooc ee TV-yada^(TVs) , ama aad u rogtey xagga hoose si aad jawaabta fudud u hesho, waxaan kuu haynaa war xun: ma jirto jawaab fudud. Jawaabta waxaa go'aaminaya xaaladaada.

Haddii aad leedahay qol loo qoondeeyay oo leh nal hooseeya iyo qalab HDR awood u leh, oo aad xoogaa ku dhowdahay TV-gaga, markaa HDR ayaa adiga kuu ah. Dhanka kale, haddii aad kaliya daawato fiilada oo aadan ku bixin lacagtaas dheeriga ah mashiinka HDR , 4K si fiican ayay u fiicnaan doontaa.

4K vs HDR vs Dolby Vision: What’s the Best for Your TV?

Browsing through the TV aisle, you noticе the wide variety of acronyms used in their descriptions. Ultra HD, UHD, 2160p, 4K x 2K, 4K Ultra High Definition, Quad High Definition, Quad Resоlution, Quad Full High Definition, QFHD, UD, HDR…the list goes on. Is the extra money worth the hуpe?

4K/UHD has four times the number of pixels as 1080p, so it must be better, right? Not exactly. You may only see the change in quality if you’re at a close viewing distance or if the movie or image is native 4K content.

4K can’t improve any image under native 4K, so anything less than 4K will show no improvement. HDR (high dynamic range) doesn’t focus on adding more pixels like its 4K counterpart, but instead creates better, more dynamic pixels by boosting contrast and brightness and providing a wider range of colors.

Misdirection

A common pitch for some manufacturers who haven’t achieved the actual “HDR experience” have misdirected customers by using the phrase “HDR-capable”, or “HDR-compatible.” Although it has HDR in the name, it doesn’t mean that it can produce the same high quality, colorful HDR image. These TV’s can only read HDR metadata, which is the data encoded into the signal that tells the TV how the image is to be shown.

A big challenge for these TVs is the brightness. Top brand televisions with HDR can hit 500-1,000 nits (the unit of measurement for brightness). HDR-capable TVs support 100-300 nits, the result of which is a much more limited range of color.

There are basically two types of HDR technology currently. HDR10 has been adopted as the baseline standard for almost every TV with HDR. If you have an Ultra HD Blu-ray player, then this is the only format supported. Your other choice is an enhanced version of HDR10, known as Dolby Vision.

What Is Dolby Vision?

Dolby, the company that’s also known for Dolby Surround, has created a brand name for HDR 4K known as Dolby Vision. Manufacturers must have their equipment tested and pay to get their products certified to have the Dolby Vision logo put on their devices. The Dolby HDR format is also widely used in the professional film industry.

Dolby Vision lays out more specific instructions for compatibility. Dolby even has separate instructions for encoding and decoding Dolby Vision HDR material on specific movie productions, broadcast TV, and TV displays. This makes it much more technologically demanding than HDR10.

So HDR10 or Dolby Vision?

Dolby Vision TVs should produce an even better visual experience, but with that being said, not all TVs are created equal. These TVs provide for metadata that can change scene to scene, instructing the TV to push contrast or boost certain colors. Dolby Vision can perform up to 12-bit color depth for a possible 68 billion colors on the brightness scale, reaching up to 4,000 nits or more.

HDR10 uses a fixed set of metadata, giving less flexibility on the way your TV can produce different movies and scenes. HDR10 is also limited to 10-bit color depth for up to 1.07 billion colors. It can lack in its brightness levels when comparing it to Dolby Vision TVs, only allowing for 1,000 nits or more.

Now, Dolby Vision seems like the logical winner, right? Well, as of now, no consumer TVs are even capable of a 12-bit color depth. Dolby Visions range is hopefully a foreshadowing of future products.

Even on brightness requirements, both Dolby and HDR10 formats can be skewed. An example of this is OLED sets which can’t reach the brightness levels of LCD but can offer a superior experience when concerning lower light levels. However, both TVs qualify as HDR10 and Dolby vision compatible sets.

Get to The Point!

So, Whether you wanted the knowledge and specifics over these two types of TVs, or you just scrolled to the bottom to get the simple answer, we have bad news for you: there is no simple answer. The answer is determined by your situation.

If you have a designated room with low lighting and an HDR-capable device, and you’re somewhat close to your TV, then HDR is for you. On the flip side, if you only watch cable and haven’t spent that extra penny on an HDR machine, 4K will do just fine.
