Iibsashada shaashad cusub waa mid xiiso leh, laakiin xaashida jargon-culus ayaa kaa dhigi kara inaad dareento culays. Mid ka mid ah tilmaamaha aasaasiga ah ee qeexaya waayo-aragnimadaada daawashada waa xallinta shaashadda.

Haddii aad hore ugu dartay jaangooyooyinkaaga soo bandhigida Windows, waxay u badan tahay inaad la kulantay xallinta kelmadda. Beddelidda xallinta^{(Changing the resolution)} ayaa ku caawin karta Haddii aad qabto arrin la taaban karo marka aad HDTV u isticmaalayso kormeere ahaan^{(using your HDTV as a monitor)} ama aad rabto in aad kor u qaaddo tayada bandhigga. Laakin maxaa xalin laga wadaa?

Waa maxay macnaha Xallinta Shaashada?

Qaraarka waa cabbir qeexaya hufnaanta sawirka ay soo bandhigtay shaashaddu. Erayga waxaa loo isticmaalaa labada qaybood ee qalabka sida shaashado ( TV-yada^(TVs) , kormeerayaasha, iyo shashadaha mobaylada), iyo qaybaha software sida sawirada. 

Xallinta shaashadda waxaa lagu muujiyey sida tirada pixels ee ay shaashaddu soo saarto si toos ah iyo toosan (ie, ballac x dhererka).

Halkii loo qori lahaa xallinta sida ballac x dhererka, inta badan xaashiyaha gaarka ah waxay adeegsadaan erayo ay ka mid yihiin 720p (HD), 1080p ( Full HD ), iyo 4K. Kuwani waa qaraarada inta badan la isticmaalo, ugu yaraan hadda, in kasta oo ay jiraan dhawr qaraar oo kale sida 1440p, 2K, iyo 8K, sidoo kale. 

Dhammaan go'aamadan waxaa lagu tilmaami karaa ballac x dherer:

• 480p: 640 x 480 pixels (SD)
• 720p: 1280 x 720 pixels (HD)
• 1080p: 1920 x 1080 pixels (HD oo buuxa)
• 2K: 2048 x 1080 pixels
• 1440p: 2560 x 1440 pixels
• 4K: 3840 x 2160 pixels
• 8K: 7680 x 4320 pixels

Waxaan dib ugu soo celin doonaa xallinta, laakiin aan marka hore ka hadalno waxa pixels yihiin.

Waa maxay Pixels?

pixel-ku waa dhibic shaashaddaada. Si wada jir ah, dhammaan pixels-yada shaashaddaada ku yaal ayaa ka kooban sawirrada aad ku aragto TV-gaaga ama la socodka. Haddii aad si dhab ah u eegto, waxaad arki kartaa pixel kasta sidii dhibco yaryar oo shaashadda ah.

Markasta oo pixels ay ku jiraan shaashaddaada, ayaa sii fiicnaan doonta tayada sawirka. Tani waa sababta xallinta sare ay u tarjumeyso muuqaallo wanaagsan oo qallafsan. 

Tusaale ahaan, shaashadda xallinta 4K waxay leedahay 3840 pixels bidix ilaa midig, iyo 2160 pixels kor ilaa hoose. Tani waxay ka dhigan tahay saamiga toosan iyo pixels toosan (ie, saamiga dhinaca) waa 16:9. 

Ku dhawaad ​​dhammaan qaraarada shaashadda (marka laga reebo dhowr sida 4K Ultra HD ) waxay leeyihiin saamiga dhinac ee 16:9. Tani waxay hubinaysaa isku midnimada si aanay sawirada shaashaddaadu u muuqan kuwo fidsan ama qalloocan, ama aanay lahayn wax dabool ah oo ku wareegsan xadka.

Inta badan Go'aamada Caadiga ah

720p, 1080p, iyo 4K ayaa hadda ah xallinta shaashadda ugu caansan maanta. Inaad wax yar ka ogaato go'aamadan ayaa waxtar leh marka aad isku dayayso inaad samayso go'aan xog ogaal ah oo ku saabsan shaashaddaada cusub.

Waa maxay xallinta 720p?^{(What is 720p resolution?)}

Shaashadda 720p (ie, qeexitaan sare) waxa ay leedahay 1280 x 720 pixels, taas oo macnaheedu yahay in uu leeyahay wadar ahaan 921,600 pixels. 720p wuxuu ahaa heerka warshadaha qiyaastii toban sano ka hor, laakiin tan iyo markaas waxaa lagu bedelay 1080p. Si kastaba ha ahaatee, 720p ayaa wali loo isticmaalaa shaashado badan oo yar yar.

Waa maxay xallinta 1080p?^{(What is 1080p resolution?)}

Shaashadda 1080p (ie, Full HD ) waxa ay leedahay 1920 x 1080 pixels, taas oo u turjumaysa 2,073,600 pixels. Taasi waxay labanlaab ka badan tahay inta shaashadda 720p. Haddii aad ku wareersan tahay inta u dhaxaysa 720p iyo 1080p^{(confused between 720p and 1080p)} , waxa fiican inaad doorato 1080p. Hadda waa xallinta ugu weyn taas oo inta badan waxyaabaha onlaynka ah iyo TV-ga lagu soo saaro.

Waa maxay xallinta 4K?^{(What is 4K resolution?)}

Shaashada 4K waxay leedahay 3840 x 2160 pixels ama wadar ahaan 8,294,400 pixels. Taasi waa 4x pixels ee shaashadda 1080p, ama 9x pixels ee shaashadda 720p. Si kastaba ha ahaatee, shaashadaha 4K waxay sidoo kale noqon karaan Ultra HD^{(4K screens can also be Ultra HD)} , taas oo ka duwan 4K. 

Shaashado 4K ah ayaa jiray in muddo ah, laakiin dhawaan uun bay soo galeen guud ahaan. Tani waa sababta oo ah waxay ahaan jireen kuwo aad u qiimo badan, laakiin hadda waxaa lagu heli karaa qiimo jeebka-saaxiibtinimo ka badan.

Waxyaabaha ay tahay in la tixgeliyo marka la dooranayo xal

Hadda oo aad ogtahay micnaha xallinta, waxaa laga yaabaa inaad xiiseyneyso arrimaha ay tahay inaad tixgeliso markaad dooranayso xallinta shaashadda. Labada shay ee aasaasiga ah ee ay tahay inaad tixgeliso waa cabbirka shaashaddaada iyo fogaanta daawashadaada ee shaashadda.

Cabbirka Shaashada^{(Screen Size)}

Haddii aad iibsanayso shaashad yar, dheh 24 inji, wax kasta oo ka baxsan 1080p ma samayn doono farqi weyn. Haddii aad iibsanayso shaashad 65-inch ah, waa inaad doorataa 4K ugu yaraan.

Sababta? cufnaanta Pixel. 

Cufnaanta Pixel^(Pixel) waa tirada pixels ee ku jira hal inch oo shaashadda ah, waxaana lagu cabbiraa iyadoo la isticmaalayo mitir loo yaqaan pixels per inch ( PPI ). Waa muhiim in muraayadda weyni ay leedahay xallin sare, markaa cufnaanta pixel-ku waa mid sare oo ku filan si ay u muujiso sawirro tayo wanaagsan leh. 

Tusaale ahaan, TV-ga 65-inji leh xallinta 4K wuxuu leeyahay ppi oo ku saabsan 67. Is barbar dhig taas oo leh TV 24-inch ah oo leh 1080p xallin, kaas oo leh ppi sare oo ku saabsan 91. Inkasta oo TV-ga 65-inch uu leeyahay xallin sare. , sawiradu waxay si qallafsan uga soo muuqan doonaan TV-ga 24-inch sababtoo ah cufnaanta pixel sare.

Haddii aad iibsanayso TV, ppi 90-110 ayaa loo arkaa meesha ugu macaan. Kormeeraha, waa inaad higsaneysaa ppi sare oo ku saabsan 200-250 ama ka badan, iyadoo ku xiran masaafadaada daawashada. Waxaad isticmaali kartaa xisaabiyaha ppi^{(ppi calculator)} onlaynka ah si aad u barbar dhigto shaashadaha leh cabbirro iyo xallino kala duwan.

Fogaanta Daawashada^{(Viewing Distance)}

Arrin kale oo ay tahay inaad tixgeliso waa fogaanta daawashada, taas oo ku xidhan waxa aad u isticmaasho shaashadda. Haddii aad iibsanayso TV, waxay u badan tahay inaad ka arki doonto masaafo ka weyn kan kormeeraha. Tani waxay ka dhigan tahay inaad dooran karto ppi waxyar ka hooseeya. 

Si kastaba ha ahaatee, haddii aad iibsanayso kormeeraha kombayuutarka, fogaantaada daawashada ee shaashadda waxay noqon doontaa mid yar. ppi sare wuxuu hubin doonaa inaadan ku arag pixels shaashaddaada markaad isticmaalayso.

Diyaar ma u tahay casriyeyn?

Haddii aad haysatay shaashaddaada in muddo ah, oo ay tahay waqtigii cusboonaysiinta, u fiirso 1080p ugu yaraan. Haddii aanad lahayn caqabad miisaaniyadeed oo aad iibsanayso shaashad dhexdhexaad ah ama weyn, tixgeli inaad maalgeliso shaashadda 4K.

Markaad lacag badan ku bixinayso iibsashada shaashad 4K, waa dabiici inaad ka walwasho ilaa inta ay ku sii jiri doonto. Si kastaba ha ahaatee, 8K aad ayuu uga fog yahay gelitaanka guud ahaan. Inkastoo la heli karo, si aan macquul ahayn waa qaali. 

What Does Resolution Mean When Buying a TV or Monitor?

Buying a new screen is exciting, but the jargon-heavy spec sheets cаn make you fеel overwhelmed. One of the primary ѕрecifications that defines your viewing experience is the screen’s resolution.

If you’ve tinkered with your Windows display settings in the past, you’ve probably come across the word resolution. Changing the resolution can help If you have an overscan issue when using your HDTV as a monitor or want to improve your display quality. But what does resolution mean?

What Does Screen Resolution Mean?

Resolution is a measure that describes the clarity of an image displayed by the screen. The term is used for both hardware components like screens (TVs, monitors, and mobile screens), and software components like images. 

Screen resolution is expressed as the number of pixels that a screen produces horizontally and vertically (i.e., width x height).

Instead of writing the resolution as width x height, most spec sheets use terms like 720p (HD), 1080p (Full HD), and 4K. These are the most commonly used resolutions, at least currently, though there are several other resolutions like 1440p, 2K, and 8K, as well. 

All these resolutions can be expressed as width x height:

• 480p: 640 x 480 pixels (SD)
• 720p: 1280 x 720 pixels (HD)
• 1080p: 1920 x 1080 pixels (Full HD)
• 2K: 2048 x 1080 pixels
• 1440p: 2560 x 1440 pixels
• 4K: 3840 x 2160 pixels
• 8K: 7680 x 4320 pixels

We’ll circle back to resolution, but let’s first talk about what pixels are.

What Are Pixels?

A pixel is a dot on your screen. Collectively, all the pixels on your screen make up the images that you see on your TV or monitor. If you look real close, you can see each pixel as tiny dots on the screen.

The more pixels there are on your screen, the better the quality of the image. This is why a higher resolution translates to better, crisper images. 

For instance, a 4K resolution screen has 3840 pixels from left to right, and 2160 pixels from top to the bottom. This means the ratio of horizontal to vertical pixels (i.e., aspect ratio) is 16:9. 

Almost all screen resolutions (except a few like 4K Ultra HD) have an aspect ratio of 16:9. This ensures uniformity so the images on your screen don’t appear stretched or distorted, or have any padding around the border.

Most Common Resolutions

720p, 1080p, and 4K are currently the most common screen resolutions today. Knowing a little about these resolutions is helpful when you’re trying to make an informed decision about your new screen.

What is 720p resolution?

A 720p (i.e., high definition) screen has 1280 x 720 pixels, which means it has a total of 921,600 pixels. 720p was the industry standard about a decade ago, but has since been replaced by 1080p. However, 720p is still used in a lot of small-sized screens.

What is 1080p resolution?

A 1080p (i.e., Full HD) screen has 1920 x 1080 pixels, which translates to 2,073,600 pixels. That’s over twice as many as on a 720p screen. If you’re confused between 720p and 1080p, it’s best to pick 1080p. It’s currently the dominant resolution in which most of the online and TV content is produced.

What is 4K resolution?

A 4K screen has 3840 x 2160 pixels or a total of 8,294,400 pixels. That’s 4x the pixels on a 1080p screen, or 9x the pixels on a 720p screen. However, 4K screens can also be Ultra HD, which is different from 4K. 

4K screens have been around for a while, but have only recently entered the mainstream. This is because they used to be fairly pricey, but they’re now available at a much more pocket-friendly price.

Things to Consider When Choosing a Resolution

Now that you know what resolution means, you may be curious as to what factors you should consider when choosing a screen resolution. The two primary things you should consider are your screen’s size and your viewing distance from the screen.

Screen Size

If you’re buying a small screen, say 24 inches, anything beyond 1080p won’t make a significant difference. If you’re buying a 65-inch screen though, you should choose 4K as a minimum.

The reason? Pixel density. 

Pixel density is the number of pixels packed in one inch of the screen, and is measured using a metric called pixels per inch (PPI). It’s important for a large screen to have higher resolution, so the pixel density is high enough to display good quality images. 

For instance, a 65-inch TV with 4K resolution has a ppi of about 67. Compare that with a 24-inch TV with 1080p resolution, which has a higher ppi of about 91. Even though the 65-inch TV has a higher resolution, the images will appear crisper on the 24-inch TV because of higher pixel density.

If you’re buying a TV, a ppi of 90-110 is considered the sweet spot. For a monitor, you should aim for a higher ppi of about 200-250 or more, depending on your viewing distance. You can use an online ppi calculator for comparing screens with different sizes and resolutions.

Viewing Distance

Another factor you should consider is the viewing distance, which depends on what you use the screen for. If you’re buying a TV, you’ll probably view it from a greater distance than a monitor. This means you can opt for a slightly lower ppi. 

However, if you’re buying a computer monitor, your viewing distance from the screen will be relatively less. A higher ppi will make sure that you don’t see pixels on your screen while you’re using it.

Ready for an Upgrade?

If you’ve had your screen for a while, and it’s time for an upgrade, aim for 1080p as a bare minimum. If you don’t have a budget constraint and are buying a medium or large screen, consider investing in a 4K screen.

When you’re spending a lot of money buying a 4K screen, it’s natural to worry about how long it will stay relevant. However, 8K is far from entering the mainstream. Though available, it’s impractically expensive.
