Tani waa da'dii tack-fiiqan ee telefishinnada Ultra High Definition^{(Ultra High Definition televisions)} , haddaba muxuu sawirka TV-gaagu u yahay mid aan mugdi lahayn ama daahsoon?

Waxaa laga yaabaa inaad u baahato warqad dhakhtar cusub ookiyaalahaaga. Laakin haddii aysan waxba ka xumaanin indhahaaga, waa inaad xallisaa si aad u hesho sawirka ugu fiican.

1. In meesha laga saaro ilaha faragelinta

Qaar ka mid ah blur LCD ama arrimaha ghosting waxay ka dhashaan faragelinta korantada ama ilaaliyayaasha qallafsan. Si taas loo baabi'iyo sabab ahaan, isku day inaad TV-gaaga si toos ah ugu xirto meesha laga baxo adiga oo aan lahayn wax koronto ah ama wax xakameynaya silsiladda. Haddii taasi xalliso dhibaatada, waxaad isku dayi kartaa inaad isticmaasho xariijin koronto oo kale.

Waa inaad sidoo kale isku daydaa inaad damiso aaladaha isla wareegga TV-ga. Qalab kasta oo leh matoor AC, sida talaajad, qaboojiyaha, ama marawaxad waxay keeni kartaa faragelin koronto. Uma badna in aaladahani ay la mid yihiin wareegga laga soo galo TV-gaga, laakiin waxaa habboon in la hubiyo.

Haddii aad leedahay koronto isbedbeddelaysa oo si toos ah uga imanaysa dhexda, UPS oo shaandhaysa xadhkahaan ayaa laga yaabaa inay xal u noqoto, laakiin waxaad u baahan doontaa koronto yaqaan si uu u hubiyo sahaydaada.

2. Ishaagu ma tahay mid xalkeedu hooseeyaa?

Mid ka mid ah sababaha ugu badan ee sawirka blushka ah ee shaashada fidsan ee LCD TV (ama kormeeraha) waa ismaandhaaf u dhexeeya xallinta nuxurka iyo awoodda xallinta dhaladka ee shaashadda.

LCD, Mini-LED, microLED , Plasma , OLED , ama QD-OLED dhamaantood waxay isticmaalaan noocyo kala duwan oo tignoolajiyada si ay u sameeyaan sawiro dhaqaaqa. Si kastaba ha ahaatee, hal shay oo ay dhamaantood ka siman yihiin ayaa ah xallinta "dhaladeed". Tani waxa ay tilmaamaysaa xadhkaha TV-ga ee pixels-ka jirka (sawirka canaasirta). 4K UHD TV waxa uu leeyahay shabag pixel 3840 x 2160 pixels. Tani waxay afar jeer ka badan tahay pixels ka badan TV-ga Full HD oo ah 1920×1080. Markaa, pixel kasta oo macluumaad ah oo ku jira isha sawirka Full HD , TV-gu waa inuu buuxiyaa afar pixels 'qiimaha xogta.

Waxaa jira habab kala duwan oo ah "kor u qaadista" sawirada hoose ee bandhigyada xallinta sare, dhammaantoodna waxay leeyihiin heerar kala duwan oo guulo ah. Ka bixitaanka FHD^(FHD) ee UHD waa mid toos ah maadaama ay ku lug leedahay samaynta kooxo afar pixels u dhaqmaan sidii hal pixels. Mar kasta oo xallinta sawirka isha si siman u qaybsanto xallinta shaashadda bartilmaameedka, waxaad heli doontaa sawir jilicsan, laakiin wali waxay u muuqan doontaa mid wanaagsan.

Haddi isha aysan si fiican ugu qeybin bartilmaameedka, waxaa laga yaabaa inaad hesho natiijo fool xun. Qaar badan oo ka mid ah hagaajinta hoos ku taxan ayaa kaa caawin kara hagaajinta natiijooyinka kor u kaca ee blur ama wareerka leh.

3. Beddel Dejinta Kor-u-qaadistaada (ama Kor-u- qaadkaaga^(Settings) )

TV-yo^(TVs) kala duwan iyo aaladaha sanduuqa set-top waxay bixiyaan doorashooyin kala duwan oo ku saabsan sida ay tahay inay u cabbiraan ilaha xallinta hoose ilaa shaashad heer sare ah. Halkan si gaar ah uguma noqon karno sababtoo ah aaladaha iyo TV-yada^(TVs) kala duwan waxay leeyihiin magacyo kale iyo nidaamyada menu. Markaa waxa fiican inaad ka raadiso buug-gacmeedkaaga ama khadka tooska ah wax kasta oo la xidhiidha “kor u qaadista” iyo qalabkaaga.

Mid ka mid ah tilmaanta muhiimka ah ee aan ku siin karno waa inaad iska ilaaliso in TV-ga laftiisa uu sameeyo kor u kaca. Telefishinada dhamaadka-sare waxa laga yaabaa inay lahaadaan tignoolajiyada kor u kaca, laakiin kuwa dhexe iyo kuwa hooseeya guud ahaan ma laha awooda farsamaynta si ay kor ugu qaadaan natiijooyin wanaagsan.

Taa baddalkeeda, haddii aad isticmaaleyso aalad ku xiran sida sanduuqa fiilada, console-ka ciyaarta, TV-ga Android , Apple TV , ama ilo kale oo la mid ah, deji xallinta wax-soo-saarka si ay ugu habboonaato xallinta TV-gaaga hooyo. Kor u qaadis kasta ayaa ku dhici doonta qalabkaas ka hor inta uusan gaarin TV-ga.

4. Beddel Goobaha Tayada Sawirkaaga^{(Picture Quality Settings)}

Haddii aad daawato il fiidiyoow ah oo qulqulaya (sida Netflix ama app Hulu ee TV-ga caqliga leh), markaa sawirka daahsoon ayaa laga yaabaa inuusan wax xiriir ah la lahayn TV-gaaga iyo wax kasta oo la xiriira bandwidth-kaaga ama goobaha tayada.

Tag goobaha sawirka ee abka aad dooratay ee daawashada oo deji tayadaada iyo isticmaalka xadhkaha goosashada. Qaar ka mid ah abka qulqulka ah (tusaale, Disney Plus ), waxaad dooran kartaa tayada aad doorbidayso markaad daawanayso macluumaadkaaga. Ka beddel goobta tayada otomaatigga ah una beddel meel u dhigma waxa TV-gaagu loogu talagalay inuu soo bandhigo.

Maskaxda^(Bear) ku hay in xidhiidhkaaga intarneetku uu si fudud u noqon karo mid aad gaabis u ah in lagu shubo tayada ugu fican ee TV-gaga. Waxa kale oo laga yaabaa inay qaadato dhowr ilbiriqsi in qulqulku u wareego qaabka tayada sare leh. Waxa kale oo jira "bitrates" tayo kala duwan oo ku dhex jira heer kasta oo xallinta. Marka in kasta oo laga yaabo inaad ku qulqulayso (tusaale ahaan) 4K, haddii ay ku taal dhamaadka hoose ee bitrate ee xallinta, wali waxaa jiri kara blur, wareer, ama waxyaabo kale oo sawirka ku jira.

5. Isha ma Digital baa mise Analog?

HDMI waa heerka sawirka dhijitaalka ah, kaas oo hubinaya inaad hesho tayada isha iyada oo aan hoos loo dhigin. Haddii aad isticmaalayso isha analooga ah, sida ciyaaryahan DVD ah oo ku xidhan iyada oo la isticmaalayo isku xidhayaasha RCA , waxa jiri kara xaddi laxaad leh oo faragelin ah ama calaamad lumis ku salaysan dhawr arrimood.

Haddii ay suurtogal tahay, beddel HDMI u beddel . Ku soo noqoshada tusaalaha ciyaartoyga DVD-ga^(DVD) , moodooyinka qaarkood waxay bixiyaan wax soo saarka HDMI waxayna leeyihiin kor-u-qaadayaal gudaha ah oo loogu talagalay inay ka dhigaan muuqaallada DVD-ga inay u eegaan ^(DVD)HDTV^(HDTVs) -yada casriga ah .

6. Isku day Kaalbo HDMI^{(Different HDMI Cable)} ah oo ka duwan ama Deked^(Port)

HDMI waa dhijitaal, iyo sida caadiga ah, waxay u shaqeysaa si sax ah ama maba aha gebi ahaanba. Waxaan aragnay xaalado, in kastoo, halka dekedaha xun ama fiilooyinka ay keeni karaan baraf ama sawiro kale oo muuqaal ah. HDMI waxaa loo dhisay in ay yeelato heer go'an oo ah sixitaanka qaladka dhijitaalka ah. Si kastaba ha ahaatee, haddii qadarka faragelinta korantada ama dhaawaca fiilada ama dekeddu ay dhaafto xadka, waxa laga yaabaa inay hoos u dhigto sawirka.

Mid ka mid ah hagaajinta fiidiyoowga blur ama daahsoon ayaa ah in la damiyo fiilada HDMI ama loo raro gelinta kale ee TV-ga si loo hubiyo haddii ay wax ka khaldan yihiin fiilada ama dekedda.

7. Beddel goobaha fiiqan

Ku dhawaad ​​dhammaan TV-yada casriga ah ee HDTV^(HDTVs) -yada waxay bixiyaan qaab fiiqid dhijitaal ah. Tani waxay inta badan ku hoos qoran tahay goobaha TV-ga oo ay weheliso isbarbardhigga, dhalaalka, iwm. Isticmaal kontoroolka fogaanta ee TV-ga si aad u gasho menu-yadaas, badanaa adiga oo marka hore riixaya badhanka menu-ka. 

Hoos u dhigista heerka fiiqan ayaa jilcin doonta sawirka. Waxa laga yaabaa in goobtaada afifaysan tahay waxyaalihii aad u jilciyey oo muuqaalku u ekaado mid blur ah ama dawakhsan. Jawaabtu, dabcan, waa inaad kor u qaaddo fiiqan ilaa aad ku faraxsan tahay natiijada.

Kordhinta shaandhada afaynta sidoo kale waa hab wax ku ool ah oo lagula tacaalayo blurness ee sawirka isha. Weli, waxa jira wax badan oo la samayn karo ka hor inta sawirku u ekaan mid aad u afaysan oo aan rafcaan lahayn.

8. Daar Astaamaha Yaraynta Dareema

Si ka duwan TV-yada CRT ( cathode ray tube ) , dhammaan TV-yada ^(TVs)casriga^(TVs) ah ee-screen-flat waxa ay soo bandhigaan nooc ka mid ah blur dhaqdhaqaaqa oo loo yaqaano muunad-iyo-hays blur. Intaa waxaa dheer, TV-yada^(TVs) -dhamaadka hoose ayaa laga yaabaa inay yeeshaan blur-dhammaan maadaama pixels-ka shaqsiyeed ay si tartiib tartiib ah u beddelaan xaaladdooda.

Shirkadaha sida Samsung iyo Sony waxay si hagar la'aan ah uga shaqeeyeen inay abuuraan tignoolajiyada guddi cusub si ay ula dagaallamaan arrimahan. Haddii aad haysato TV duug ah, waxa laga yaabaa in aanu ka faa'iidaysan waqtiyada jawaabta pixel ee degdega ah ee moodooyinka ugu dambeeyay ay gaadhi karaan.

Dhanka blur-ka dhaqaaqa ee ay sababtay muunada-iyo-haynta dabeecadda tignoolajiyada golaha fidsan, waxa jira laba sifo oo muhiim ah oo aad dhaqaajin karto si aad ula dagaallanto. Midda koowaad waa hab-socod-dhaqaaleedka, oo sidoo kale loo yaqaanno dhex-dhexaadinta. Noocyada kala duwan ee TV-ga^{(Different TV)} waxay leeyihiin magacyo kale, markaa waa inaad raadisaa wax tilmaamaya dhaqdhaqaaqa, jilicsanaanta, ama samee shabakad ka raadi qaabka TV-gaaga oo leh ereyga "dhaqdhaqaaqa dhaqdhaqaaqa."

Habkani waxa uu ka abuuraa fiimyo cusub fiimyada jira ee fiidyaha si ay u bixiyaan dhaq-dhaqaaq dareere-dheex ah oo aan blur lahayn. Tani waa "saamaynta opera saabuunta" ee aadka loo yaso, laakiin waxa laga yaabaa inaad door bidayso qallafsanaanta qaabkan nuxurka qaarkood, sida baahinta ciyaaraha HD.

Muuqaalka labaad waa wax loo yaqaan Gelida Qaabka Madow^{(Black Frame Insertion)} ( BFI ). Tani waxay gelinaysaa jir madow inta u dhaxaysa jir kasta oo lagu soo bandhigay shaashadda. Tani waxay ka dhigaysaa in bandhiga TV-gu u dhawaado bandhigga CRT ee garaaca , sidaas darteed jabinta muunadda-iyo-haysnaanta. Si kastaba ha ahaatee, tani waxay ku timaadaa qiimaha dhalaalka iyo firfircoonida. TV-yada cusub^{(Newer TVs)} uma dhibtoodaan sida moodooyinka duugga ah, laakiin si kastaba ha noqotee, waad beddeli kartaa astaanta oo go'aan ka gaartaa sawirka aad doorbidayso.

9. Dami sawirka ka dib habaynta

Astaamaha shaqada ka dib ayaa ah dhammaan waxyaabaha uu TV-gu ku sameeyo sawirka ka hor inta uusan soo bandhigin. Soosaarayaasha TV-ga waxay leeyihiin "Suugo sir ah" algorithms kuwaas oo ka caawiya inay sawiradu si fiican u muuqdaan, laakiin wax-qabad badan oo ka dambeeya waxay ka tagi karaan sawir jilicsan oo jilicsan.

Demi inta badan saamaynta habaynta ka dib ee suurtogalka ah, adoo isticmaalaya buug-gacmeedka TV-ga hage ahaan, ka dibna tijaabi kuwa bixiya sawirka ugu fiican adoon keenin blur badan. Dhimista qaylada^(Noise) waxay noqon kartaa mid ka mid ah goobaha ugu muhiimsan ee lagu hagaajinayo haddii aad la kulanto baraf ama sawir dhibicyo leh.

10. Qaado Qiimayn Xirfadeed

Haddii wax aad korka isku dayday ay u muuqato in ay xalliso TV-gaaga jahawareerka ah, ee aadka u qallafsan, waxa ay u badan tahay in la gaadhay waqtigii qof farsamo yaqaan ah uu eegi lahaa TV-gaaga. Xaaladaha qaarkood, waxay noqon kartaa mid fudud sida beddelidda qayb aan qaali ahayn. Laakiin haddii ay jiraan wax ka khaldan qaybaha asaasiga ah ee TV-ga, inta badan maaha mid u qalma kharashka si loogu beddelo qaybahaas waaweyn. Haddii TV-gaagu wali ku jiro dammaanad, waa inaad ka fogaataa inaad qofna u ogolan inuu ka shaqeeyo, xitaa haddii ay tahay dhibaato yar. Taa beddelkeeda, ha la dayactiro oo ha lagu beddelo dammaanadda.

Is Your TV Screen Blurry or Fuzzy? Try These 10 Fixes

This is the age of tack-sharp Ultra High Definition televisions, so why is your TV’s picture so blurry or fuzzy?

You might need a new prescription for your glasses. But if there’s nothing wrong with your eyes, you’ll have to troubleshoot to get the best picture.

1. Remove Sources of Interference

Some LCD blur or ghosting issues result from electrical interference or faulty surge protectors. To eliminate this as a cause, try plugging your TV directly into the outlet without any power strips or surge suppressors in the chain. If that solves the problem, you can try using a different power strip.

You should also try switching off devices on the same circuit as the TV. Any device with an AC motor, such as a fridge, air conditioner, or fan can cause electrical interference. It’s unlikely that these devices would be on the same circuit as the outlet for your TV, but it’s worth checking.

If you have fluctuating power coming directly from your mains, a UPS that filters out these spikes may be the solution, but you’ll need an electrician to check your supply.

2. Is Your Source Low Resolution?

One of the most common causes of a blurry picture on a flat-screen LCD TV (or monitor) is a mismatch between the content’s resolution and the native resolution capability of the screen.

LCD, Mini-LED, microLED, Plasma, OLED, or QD-OLED all use different types of technology to make moving pictures. However, one thing they all have in common is a “native” resolution. This refers to the TV’s grid of physical pixels (picture elements). A 4K UHD TV has a pixel grid of 3840 x 2160 pixels. This is four times as many pixels as a Full HD TV at 1920×1080. So, for every pixel of information in a Full HD image source, the TV must fill four physical pixels’ worth of data.

There are various methods of “upscaling” lower-resolution images to high-resolution displays, and they all have varying levels of success. Going from FHD to UHD is straightforward since it involves making groups of four pixels act as a single pixel. Whenever the resolution of the source image divides evenly into the target screen’s resolution, you’ll get a softer image, but it will still look good.

If the source doesn’t divide perfectly into the target, you may get an ugly smeary result. Many of the fixes listed below can help to fix blurry or fuzzy upscaling results.

3. Change Your Upscaling Settings (Or Your Upscaler)

Various TVs and set-top box devices offer different options regarding how they should scale lower-resolution sources to a higher-resolution screen. We can’t be very specific here because different devices and TVs have other names and menu systems. So you’re better off looking in your manual or online for anything to do with “upscaling” and your devices.

One important tip we can give you is to avoid having the TV itself do the upscaling. High-end televisions may have superior upscaling technology, but mid-range and low-end sets generally don’t have the processing power to upscale with good results.

Instead, if you’re using a connected device like a cable box, gaming console, Android TV, Apple TV, or another similar source, set its output resolution to match your TV’s native resolution. Any upscaling will happen on that device before it reaches the TV.

4. Change Your Streaming Picture Quality Settings

If you are watching a streaming video source (such as the Netflix or Hulu app on a smart TV), then the fuzzy image may have nothing to do with your TV and everything to do with your bandwidth or quality settings.

Go to the picture settings of your streaming app of choice and set your quality and bandwidth usage preference. With some streaming apps (e.g., Disney Plus), you can select the preferred quality while watching your content. Change the quality setting from automatic to a setting that matches what your TV was designed to display.

Bear in mind that your internet connection may simply be too slow to stream at your TV’s sharpest quality. It may also take a few seconds for the stream to switch to the higher-quality mode. There are also different quality “bitrates” within each resolution tier. So although you may be streaming at (for example) 4K, if it’s at the lower end of the bitrate for that resolution, there can still be blurring, fuzziness, or other artifacts in the picture.

5. Is the Source Digital or Analog?

HDMI is a digital image standard, ensuring you get the source’s quality without degradation. If you’re using an analog source, such as a DVD player connected using RCA connectors, there can be a significant amount of interference or signal loss based on several factors.

If at all possible, switch to HDMI instead. Returning to our DVD player example, some models provide HDMI output and have internal upscalers designed to make DVD footage look sharper on modern HDTVs.

6. Try a Different HDMI Cable or Port

HDMI is digital, and usually, it works correctly or not at all. We have seen situations, though, where bad ports or cables can cause snow or other image artifacts. HDMI is built to have a certain level of digital error correction. However, if the amount of electrical interference or damage to a cable or port passes a threshold, it may degrade the image.

One fix for a blurry or fuzzy video is to switch out the HDMI cable or move it to another input on the TV to check if there might be something wrong with the cable or the port.

7. Change The Sharpness Settings

Virtually all modern HDTVs offer a form of digital sharpening. This is usually listed under TV settings alongside contrast, brightness, etc. Use your TV remote control to access those menus, usually by first pressing the menu button. 

Lowering the sharpness level will soften the image. It might be that your sharpness setting has softened things so much that the display looks blurry or fuzzy. The answer, of course, is to turn the sharpness up until you’re happy with the result.

Increasing the sharpness filter is also an effective way to deal with blurriness in the source footage. Still, there’s only so much that can be done before the image looks over-sharpened and unappealing.

8. Turn On Blur-Reduction Features

Unlike CRT (cathode ray tube) TVs, all modern flat-screen TVs exhibit a type of motion blur known as sample-and-hold motion blur. In addition, lower-end TVs may have inherent blur as the individual pixels change their state too slowly.

Companies like Samsung and Sony have worked tirelessly to create new panel technologies to combat these issues. If you have an old TV, it may not benefit from the fast pixel response times more recent models can achieve.

As for motion blur caused by the sample-and-hold nature of flat panel technology, there are two main features you can activate to combat it. The first is motion smoothing, also known as frame interpolation. Different TV brands have other names, so you’ll have to look for something that refers to motion, smoothness, or do a web search for your TV model with the term “motion smoothing.”

This feature creates new frames from the existing frames in the video to offer liquid-smooth blur-free motion. This is the much-derided “soap opera effect,” but you may prefer the crispness of this mode for some content, such as HD sports broadcasts.

The second feature is something known as Black Frame Insertion (BFI). This inserts a black frame between every frame displayed on the screen. This makes the TV offer motion closer to a pulsed CRT display, thus defeating sample-and-hold blur. However, this comes at the cost of brightness and vibrancy. Newer TVs don’t suffer as much as older models, but either way, you can switch the feature on and decide which image you prefer.

9. Turn Off Image Post-processing

Post-processing features are all of the things that the TV does to the image before displaying it. TV manufacturers have a “secret sauce” of algorithms that help make images look better, but too much post-processing can leave a soft and blurry image.

Turn off as many post-processing effects as possible, using your TV manual as a guide, and then experiment with the ones that offer the best picture without causing too much blur. Noise reduction may be one of the most important settings to adjust if you’re experiencing a snowy or speckled image.

10. Get a Professional Assessment

If nothing you’ve tried above seems to resolve your fuzzy, blurry TV, it’s probably time to have a professional tech support person look at your TV. In some cases, it may be as simple as replacing a relatively inexpensive component. But if there’s something wrong with the core components of the TV, it’s often not worth the expense to replace those major parts. If your TV is still under warranty, you should refrain from letting anyone work on it, even if it is a minor problem. Instead, have it repaired and replaced under warranty.
