Macaamiisha elektaroonigga ah sida TV-yada iyo taleefannada waxaa badanaa lagu suuq geeyaa ereyo tignoolajiyadeed cusub oo ay fududahay in lagu dhejiyo bannaanka sanduuqa. Taasi^(Which) waa sababta aad u aragto astaamo leh ereyo ay ka mid yihiin " 4K ", " HDR " iyo dhawaaqyo kale oo tignoolajiyadeed oo lagu xardhay agabka suuqgeynta. 

Hadda " 120Hz " waxay ku biirtay liiska sifooyinka la iibin karo ee labada nooc ee alaabtan. Maxay tani ka dhigan tahay? A "120Hz TV" waxaa loola jeedaa "qiimaha soo cusboonaadey" ee shaashadda TV, taas oo u baahan kaliya sharaxaad yar.

Waa maxay macnaha "Qiimaha Cusbooneysiinta"?

Heerka soo kicinta ayaa qeexaya inta jeer ee shaashaddaadu si buuxda u cusboonaysiin karto sawirka ay muujinayso. Markaa shaashadda 120Hz TV waxay soo bandhigi kartaa 120 sawir oo cusub ilbiriqsi kasta! Waa fikrad fudud, laakiin waxay saameyn weyn ku leedahay waxa sawirku u eg yahay.

Qiyaasta dib-u-cusboonaysiinta waxay la xiriirtaa "qiimaynta qaab-dhismeedka" ee macluumaadka aad daawanayso. Taasi waa, immisa xabbo oo gaar ah ayaa sekan ilbiriqsi kasta muddada fiidyaha. Mar kasta oo meeraha ay jiraan ilbiriqsi kasta, waa sida fudud ee dhaqdhaqaaqa u soo muuqan doono. Haddii nuxurku leeyahay cabbir jireed oo ka sarreeya heerka soo kicinta ee shaashadda, markaa ma arki doontid faa'iido tafaasiisha dhaqdhaqaaqa dheeraadka ah.

Heerka Cusbooneysii Vs. Qaraarka

Waxay u badan tahay inaad horeba u taqaannay fikradda "xallinta" marka ay timaado shaashadaha casriga ah. Tani waa tirada "pixels" ee sawirka ka kooban. Markasta oo uu xalintu sarreeyo, ayaa si fiican u faahfaahinaya sawirka. Tani waxay u qaadanaysaa inaad muujinayso sawir ka kooban tafaasiil ku filan oo la mid ah waxa shaashadu awood u leedahay inay soo bandhigto!

Heerka soo kicinta ayaa xoogaa la mid ah xallinta. Dhab ahaantii, waxaa mararka qaarkood loo yaqaan xallinta "ku meel gaadh ah". Waa cadadka tafaasiisha mooshinka ee la soo bandhigi karo muddo ka dib, iyada oo ka soo horjeeda wadarta cadadka tafaasiisha ee lagu muujin karo hal jir.

Bandhigyada 120Hz maaha inay noqdaan xallin gaar ah. 120Hz TV-yada, unugyada intooda badani waxay bixin doonaan xallinta sawirka 4K, laakiin waxaa laga yaabaa inaad hesho tusaalayaal bixiya heerkaas soo kicinta ee xallinta hoose. Haddaba xasuusnoow inaad labadan sifo si gooniya u qiimeyso. 

Waxa kale oo muhiim ah in la hubiyo in fursadaha isku xidhka ee TV-gaagu ay taageeraan 120Hz xallinta aad rabto. TV-ga leh xiriiriyaha HDMI 2.1 wuxuu awood u leeyahay 120Hz marka loo eego 4K. Wax kasta oo ka hooseeya kan si rasmi ah uma taageerayo xallintan iyo dib u cusboonaysiinta isku darka heerka.

Waa maxay sababta 120Hz ay ​​muhiim ugu tahay TV-yada

Ku dhawaad ​​TV kasta oo ku jira guryaha iyo khaanadaha maanta waxa uu taageeraa ugu yaraan 60Hz. Hadda, kama heli doontid wax muuqaal ah oo ku jira aaladaha sida YouTube oo ku shaqeeya heer cusub oo soo cusboonaysiin ah. Waxyaabaha shaleemada ah, 24 fiim ilbiriqsikiiba waa caadada, iyadoo tijaabada marmar lagu sameeyay heerar sare, sida filimada Hobbit oo lagu bixiyay 48 fiim ilbiriqsikii. Inta badan waxyaabaha ku jira taleefishinku waxay ku jiraan 30 fiim ilbiriqsikii. Marka, sida aad arki karto, waxaa jira wax yar haddii wax la daawado ka sarreeya 60Hz.

Arrimuhu aad bay u kala duwan yihiin markaan u beddelno kombuyuutarrada ama consoles-yada ciyaaraha. Jiilkii ugu dambeeyay ee consoles-yada ciyaaraha ayaa awood u leh inay soo saaraan heerar qaabeysan 120Hz, iyadoo ku xiran cinwaanka. Markaa cinwaannada ku socon kara xawaarahaas, waxaad la kulmi doontaa dabacsanaan iyo ka jawaab celin cajiib ah.

Waa maxay sababta 120Hz ay ​​muhiim ugu tahay taleefannada iyo tablet-yada

In kasta oo kiiska 120Hz ee TV-ga uu ku saabsan yahay dareeraha ugu dambeeya, waxaa jira cabbir dheeri ah oo ku saabsan taleefannada iyo tablet-yada. Taasi waa sababta oo ah taleefanka casriga ah shaashadda kaliya maahan wax aad eegto. Waa interface taabasho leh. 

Dheecaannada shaashadda 120Hz waxay wanaajisaa dareenka isticmaalka is dhexgalka taabashada. Sida caadiga ah ogaanshaha taabashada ee taleefannadan noocan oo kale ah ayaa sidoo kale lagu dejiyay in lagu muunado taabasho 120Hz ah, taas oo ka dhigaysa taleefoonka dareen degdeg ah oo dareen leh in la isticmaalo. Dad badan oo isticmaalay taleefannada casriga ah ee 120Hz ayaa dareemaya in 60Hz interfaces ay hadda dareemayaan caajisnimo, iyada oo aan loo eegin sida ugu dhakhsaha badan ee soo-saareyaasha gudaha.

Taleefannada 120Hz waxay leeyihiin faa'iidooyin ganacsi si kastaba ha ahaatee. Sida caadiga ah talefanku waa inuu ku shaqeeyaa xal wax yar ka hooseeya inta ay awood u leedahay shaashaddiisu, taas oo keenta sawir yar oo fiiqan. Taleefannada 120Hz sidoo kale aad bay u gaajeysan yihiin, in kasta oo ay bixiyaan ikhtiyaarrada badbaadinta awoodda, sida hoos u dhigista heerka soo kicinta ee habka badbaadinta batteriga.

Tilmaamaha Bandhigga kale ee la tixgeliyo

Heerka soo kicinta ee shaashadu waa hal qayb oo saamaynaysa tayada sawirka guud. Sidii aan horay u soo sheegnay, xaaladaha qaarkood 120Hz qaabka wuxuu u baahan yahay hoos u dhigista sawirkaaga. 120Hz TV oo aan lahayn astaamo ay ka mid yihiin HDR ama heerar madow oo wanaagsan ayaa laga yaabaa inay ka xumaadaan doorashada guud marka loo eego qaabka 60Hz ee leh astaamahan.

Markaa waa inaadan waligaa u oggolaan in nambar suuqgeyn ah sida "120Hz" ay kugu lulaan dhinac ama si kale. Hase yeeshe^(Rather) , u fiirso aaladda si guud oo uga fiirso marka loo eego waxa aad dhab ahaantii isticmaali doonto iyo kiisaska isticmaalka aad u hayso.

Ka digtoonow TV-yada "been abuur ah" 120Hz!

TV-^(TVs) yo badan ayaa taxaya heerka "wax ku oolka leh" ee 120Hz ama qaar kale oo heer sare ah. Si kastaba ha ahaatee, waxa TV-yadani^(TVs) ay dhab ahaantii sameeyaan waa isticmaalka farsamo sida galitaanka fareemka madow ama dhex galka dhexda si dhaqdhaqaaqa u ekaado mid siman.

Si kastaba ha ahaatee, dhab ahaantii ma arkaysid in ka badan 60 fiim oo fiidiyoow ah ilbiriqsikiiba, maadaama fareemada been abuurka ah aysan ku jirin macluumaad cusub. Had^(Always) iyo jeer raadi heerka 120Hz (ama ka sare) ee dhalashada haddii aad rabto heshiiska dhabta ah!

120Hz ma adigaa?

Halkan waxaan gaadhnay gunta hoose. Ma tahay inaad u cusboonaysiiso TV-gaaga hadda ama taleefankaaga mid leh shaashad 120Hz ah?

Dhinaca TV-ga ee isla'egta, dadka kaliya ee ay tahay in ay dhab ahaantii tixgaliyaan u boodada 120Hz muddada gaaban waa cayaartoyda. Ciyaartoyga cusub ee loo yaqaan ' PlayStation 5 ' iyo Xbox Series S iyo X consoles'ka ayaa ku siin kara waxyaabaha ciyaarta ka kooban ilaa 120 fiim ilbiriqsikii. Tani waa casriyeyn muhiim ah. Haddii aad leedahay PC ciyaar awood leh, waxaa jira kormeerayaal taageera ilaa 240Hz maadaama kaarka garaafyada uu soo saari karo heer ka sarreeya 120.

Haddii aad ka fekereyso inaad hesho mid ka mid ah consoles-yadan cusub, waxaa habboon in aad soo iibsato 120Hz TV oo leh awood 4K ah. Noocyada kale ee ka kooban, ma jiraan wax degdeg ah oo dhan. Dhab ahaantii, dadka intooda badan ma jecla muuqaalka muuqaalka heerka sare marka ay timaado filimada iyo bandhigyada TV-ga.

Marka ay timaado taleefannada 120Hz, ciyaaruhu sidoo kale waxay helayaan horumar wanaagsan. Iyadoo loo maleynayo in taleefanka su'aasha uu ku socon karo ciyaarta xawaarahaas. Si kastaba ha noqotee, qiimaha dhabta ah ee 120Hz wuxuu ku yimaadaa khibradda isticmaale ee taabashada leh. Aaladaha mobilada ee 120Hz waxay dareemayaan firfircooni iyo firfircooni dheeraad ah. Waa kacaan adeegsiyeed oo qof walba uu qadarin doono. Inkastoo aysan ahayn sabab aad isla markiiba u tuurto casrigaaga casriga ah, dadka intooda badan waxay taleefannada ku iibsadaan wareeg beddelaad ka gaaban kan telefishannada. 

Taladayada marka wakhtigaas yimaado waa in la raadiyo taleefoon gacanta ah oo bixisa 120Hz gelinta iyo soo bandhigida. Horumarka shakhsi ahaaneed ee ka jawaab celinta iyo dareenka ayaa ah mid aad u cajiib ah, oo aan ku qanacsanahay in aan niraahno bandhiga 120Hz waa inuu ahaadaa ugu yaraan taleefannada iyo kiniiniyada horeba.

120Hz TVs and Phones Are Here: Do You Need It?

Consumer electronics such as TVs and phonеs are often marketed with new technology buzzwords that are easy to stick on the оυtsidе of thе box. Which is why you see icons with tеrms like “4K”, “HDR” and other technology soundbites emblazoned on the marketing materials. 

Now “120Hz” has joined the list of marketable features for both of these product types. What does this mean? A “120Hz TV” refers to the “refresh rate” of the TV screen, which needs just a little explanation.

What Does “Refresh Rate” Mean?

The refresh rate describes how often your screen can completely update the image it’s displaying. So a 120Hz TV screen can display 120 unique fresh images every second! It’s a simple concept, but it has a significant impact on what the image looks like.

Refresh rate is related to the “frame rate” of the content you’re viewing. That is, how many unique still frames for every second of the video’s duration. The more frames there are each second, the smoother the motion will appear. If the content has a frame rate higher than the refresh rate of the screen, then you’ll see no benefit from the extra motion detail.

Refresh Rate Vs. Resolution

You’re probably already familiar with the concept of “resolution” when it comes to modern screens. This is the number of “pixels” that make up the picture. The higher the resolution, the finer the detail in the image. This assumes you’re displaying an image that contains enough detail to match what the screen is capable of displaying!

The refresh rate is somewhat like resolution. In fact, it’s sometimes referred to as “temporal” resolution. It’s the amount of motion detail that can be displayed over time, as opposed to the total amount of detail that can be shown in a single frame.

120Hz displays do not have to be a particular resolution. For 120Hz TVs, most units are going to offer a 4K image resolution, but you might find examples that offer that refresh rate at lower resolutions. So remember to assess these two features separately. 

It’s also important to ensure that the connection options on your TV support 120Hz at the resolution you desire. A TV with an HDMI 2.1 connector is capable of 120Hz at 4K resolutions. Anything lower than this does not officially support this resolution and refresh rate combination.

Why 120Hz Matters for TVs

Just about every TV in homes and on shelves today supports a minimum of 60Hz. Right now, you won’t find any video content on platforms like YouTube that runs at a higher refresh rate. For cinematic content, 24 frames per second is the norm, with the occasional experiment at higher rates, such as the Hobbit films which were offered at 48 frames per second. Much of television content is at 30 frames per second. So, as you can see, there’s little if anything to watch above 60Hz.

Things are very different when we switch to computers or gaming consoles. The latest generation of gaming consoles are capable of outputting frame rates at 120Hz, depending on the title. So in titles that can run at those speeds, you’ll experience incredible smoothness and responsiveness.

Why 120Hz Matters for Phones and Tablets

While the case for 120Hz on a TV is all about ultimate fluidity, there’s an added dimension on phones and tablets. That’s because on a smartphone the screen is not only something you look at. It’s a tactile interface. 

A 120Hz screen’s fluidity improves the feel of using a touch interface. Usually the touch detection on such phones is also set to sample your touch input at 120Hz, which makes the phone feel snappy and intuitive to use. Many people who have used 120Hz smartphones feel that 60Hz interfaces now feel sluggish, regardless of how fast the internal processors are.

120Hz phones do have trade offs however. Usually the phone has to run at a slightly lower resolution than its screen is capable of, resulting in a slightly less sharp image. 120Hz phones are also more power hungry, though they do offer power saving options, such as lowering the refresh rate in battery saving mode.

Other Display Features to Consider

The refresh rate of a screen is just one component that affects overall image quality. As we mentioned before, in some cases 120Hz mode requires dropping your image resolution. A 120Hz TV that lacks features such as HDR or good black levels may be a worse overall choice than a 60Hz model that does have these features.

So you should never let a single marketing number such as “120Hz” sway you one way or another. Rather, look at the device holistically and consider it in relation to the content you’re actually going to consume and the use cases you have for it.

Be Aware of “Fake” 120Hz TVs!

Many TVs list an “effective” rate of 120Hz or some other high refresh rate. However, what these TVs actually do is use a technique such as black frame insertion or frame interpolation to make motion look smoother.

However, you aren’t actually seeing more than 60 frames of video per second, since the fake frames don’t contain new information. Always look for a native 120Hz (or higher) refresh rate if you want the real deal!

Is 120Hz For You?

Here we get to the bottom line. Should you upgrade your current TV or phone to one with a 120Hz display?

On the TV side of the equation, the only people who should really consider the jump to 120Hz in the short term are gamers. The new PlayStation 5 and Xbox Series S and X consoles can offer gaming content at up to 120 frames per second. This is a significant upgrade. If you have a powerful gaming PC, there are monitors that support up to 240Hz as a graphics card can output at a frame rate higher than 120.

If you’re thinking about getting one of these new consoles, it’s worth purchasing a 120Hz TV with 4K capability. For other content types, there’s no rush at all. In fact, most people don’t like the look of high frame rate video when it comes to movies and TV shows.

When it comes to 120Hz phones, games also get a nice improvement. Assuming the phone in question can run the game at those speeds. However, the true value of 120Hz comes in the tactile user experience. 120Hz mobile devices feel dramatically more snappy and reactive. It’s a usability revolution that just about anyone will appreciate. While it’s not a reason to immediately dump your current smartphone, most people buy phones on a much shorter replacement cycle than televisions. 

Our recommendation for when that time comes is to look for a handset that offers 120Hz input and display. The subjective improvement in responsiveness and feel is so dramatic, that we’re comfortable in saying that a 120Hz display should be a minimum for phones and tablets moving forward.
