Waxaan dhawaan la kulmay arrimo yaab leh oo ku saabsan shaashadda 27 " Asus LCD . Markii aan ku dhejiyay, sawirka la soo bandhigay ma buuxinin shaashadda oo dhan, wax walbaa way qallafsanaayeen oo waxay u ekaayeen inay wax ka khaldan yihiin kormeeraha. Haddii aad leedahay arrimo isku mid ah iyo Markaad isticmaalayso kaarka fiidiyowga ee AMD/ATI , ha ka waaban inaad akhrido hagahan, sida ay soo baxday, dhibaatadan si dhakhso ah ayaa loo xallin karaa oo uma baahnid xirfado gaar ah si aad u sameyso.

Sharaxaada Dhibaatada^{(Problem Description)} : Ma jiro Sawir Shaabad Buuxa^{(Full Screen Image)} oo HD ah^{(HD Resolutions)}

Waxaan haystaa kaarka fiidiyowga ee AMD Radeon HD 6850 oo leh Asus VS278 Monitor at 27", oo awood u leh xallinta HD sida 1920x1080. Markii ugu horreysay ee aan xirto, ma rumaysan karin sida wax walba u egyihiin: sawirka "crystal clear" ee aan filayo wuxuu ahaa meelna lagama helin, Wax walba waxay lahaayeen muuqaal la maydhay, sawirka la soo bandhigay wuxuu ka buuxsamay kaliya 90% shaashadda, geesaha iyo cidhifyada shaashadu waxay ahaayeen madow, tayada sawirkuna way xumaatay.

Wax kastaa waxay u muuqdeen kuwo qallafsan, sida haddii sawirka la miisaamay oo la yareeyay algorithm macmal ah. Hoos waxaad ka arki kartaa sawirka kormeerahayga.

Waxaan u maleeyay inay wax ka khaldan yihiin kormeerahayga waxaanan ka baqay inaan soo celiyo. Si kastaba ha ahaatee, waxaan ku dhiiraday in aan xoogaa baadho, la yaabay, waxa aan ogaaday in dhibaatadani aanay naadir ahayn sidii aan moodayay.

Waxay ku dhacdaa dhammaan noocyada kala duwan ee kormeerayaasha, ka soo saarayaasha kala duwan sida Samsung , Asus ama Acer . Waxay ku dhacdaa dhammaan noocyada kaararka fiidiyowga ee AMD/ATIAMD HD 4000 ilaa kan cusub ee AMD HD 6000 iyo 7000. Sidoo kale, dhibaatadani maaha mid gaar ah oo kaliya nooc gaar ah oo fiidiyoow ah. Waxaad la kulmi kartaa markaad isticmaalayso fiilooyinka HDMI ama DVI labadaba si aad ugu xirto kaarka fiidiyowga bandhigga. Kadib, dhibaatada waxaa lala kulmi karaa labadaba Windows 7 iyo Windows 8 iyo sidoo kale marka la isticmaalayo noocyo badan oo ah Xarunta Xakamaynta Catalyst^{(Catalyst Control Center)} ( CCC ).

Dembiilaha: Qaabka Isku- beeridda^{(Scaling Setting)} ee Wax-soo-saarka Fiidiyowga ee AMD/ATI Video Output

AMD/ATI waxay leeyihiin jaangooyooyin cabbiraya darawaladooda, kaas oo u sheegaya kaadhka fiidiyowga haddii ay tahay inay wax ka beddesho wax soo saarka fiidyowga la keeno bandhigga, iyo haddii kale. Qaar ka mid ah bandhigyada Qeexida^(Definition) Sarreysa, gaar ahaan marka la isticmaalayo xallinta 1920 x 1080, cabbirka waxaa si khaldan u dejiyay darawalka.

Darawalada AMD^(AMD) waxay adeegsadaan qiimaha is-miidaminta caadiga ah waxayna leeyihiin slider aad isticmaali karto si aad u beddesho. Cidhifyadeeda waxaa lagu magacaabaa hoosta^(underscan) iyo kor-u- fiirinta^(overscan) :

• Overscan waa marka sawirka laga xiiro bandhiggu laakiin maaha kaarka fiidiyowga. Tani maaha dhibaato dunida casriga ah in kastoo. Kaliya TV-yada^(TVs) aadka u da'da weyn iyo bandhigyada ayaa u baahday sawirid xad dhaaf ah sababtoo ah waxay isticmaaleen tignoolajiyada kala duwan si ay u muujiyaan sawirka. Waagii hore^(Old) waxa uu ka dhigan yahay bandhigyo la soo saaray 1930-meeyadii ilaa 1970-meeyadii.

  Tani waxay ka dhigan tahay inay jireen meelo "aan ammaan ahayn" shaashadda oo sawirka laga xiiri karo. Bandhigyada casriga ahi waxay leeyihiin sawir-qaadis isku dhafan oo hadda waxay soo bandhigayaan waxay helayaan gelinta ahaan, pixel by pixel. Sidaa darteed, ma jirto khatar ah in sawirka laga xiiro. Taasi waa sababta darawalada kaadhka fiidiyoogu kuu ogolaanayaan inaad u dejiso dusha sare oo kaliya 0 oo aanad u dhigin qiyamka sare.

• Underscan waa ka soo horjeedka saxda ah: kaarka fiidiyowgu waa inuu xaddidaa cabbirka waxa uu u soo diro shaashadda, si uu uga hortago sawir-qaadista. Marka sawirka la hoos mariyo, sida uu xaalku yahay halkan, waxay la macno tahay in kaadhka muuqaalku aanu si sax ah u aqoonsanayn bandhigga ku xidhan iyo awoodihiisa. Waxay u malaynaysaa inay jirto khatar ah in sawirka laga gooyo bandhigga. Sidaa darteed, waxay dejinaysaa qiime hoose oo ilaa 15% ah si looga hortago dhibaatada la maleeyay.

Hagaajinta : U^(Fix) beddel heerka^{(Scaling Level)} cabbirka 0% kor u qaadista

Maaddaama bandhigyada casriga ahi aanay lahayn arrin la iska indho-tiray, looma baahna kaarka fiidyaha si uu uga hortago dhibaatadan la malaynayo iyada oo la hoos saarayo wax-soo-saarka fiidyaha ee loo soo diray.

Si loo xalliyo dhibaatadan, ku bilow inaad ku rakibto darawallada AMD/ATI ee ugu dambeeyay kaadhkaaga fiidyaha iyo nidaamka hawlgalka ee aad isticmaalayso. Waxaad ka heli doontaa halkan: AMD Graphics Drivers & Software .

Furo Xarunta Xakamaynta Matoorka ee AMD Vision^{(AMD Vision Engine Control Center)} (ama Xarunta Xakamaynta Catalyst^{(Catalyst Control Center)} sida lagu magacaabay noocyadii hore ee alaabta).

Haddii aad isticmaalayso Windows 7, aad "Desktop and Displays -> My Digital Flat-Panels -> Scaling Options (Digital Flat-Panel)" .

Haddii aad isticmaalayso Windows 8, aad "My Digital Flat-Panels -> Scaling Options (Digital Flat-Panel)" .

Qaado slider Options^{(Scaling Options)} oo dhig eber.

Dabadeed, dhagsii ama taabo Codso^(Apply) dhibaataduna waa go'an tahay. Waa kan sida sawirku u eegay kormeerayga Asus , ka dib markii isbeddelkan la sameeyay:

Si aad u fiican, miyaanay ahayn?

Gabagabo

Sida aad arki karto, dhibaatadu maaha kormeerahaaga. Looma baahna in la soo celiyo. Dhibaatada dhabta ah waa sida kaadhka fiidiyoogu u ogaado kormeeraha iyo awoodiisa. Haddii ay wax khaldamaan inta lagu jiro hawshan, waxay dejinaysaa qiyamka miisaamidda khaldan ee soo-saarka fiidyaha ee loo soo dirayo bandhigga. Waxaan rajeynayaa in casharkan uu kaa caawiyay xallinta dhibaatadaada.

Fix HD Monitors and AMD/ATI Cards Not Displaying a Full Screen Image

I recently encountered weird issues with my 27" Asus LCD display. When І plugged it in, thе image displayed did not fill the whole screen, everything was blurry and it looked like there was something wrong with the monitor. If you have sіmilar issues and you are using an AMD/ATI video card, don't heѕitate to read thiѕ guide. As it turns out, this problem can be fixеd relatively quickly and you don't need any special skills tо do it.

Problem Description: No Full Screen Image at HD Resolutions

I have an AMD Radeon HD 6850 video card with an Asus VS278 monitor at 27", capable of HD resolutions like 1920x1080. The first time I plugged it, I could not believe how terrible everything looked: the "crystal clear" image I expected was nowhere to be found. Everything had a washed-out look, the display image filled only about 90% of the screen, the corners and margins of the screen were black and the image quality was bad.

Everything looked blurry, as if the image was scaled down and made smaller by some artificial algorithm. Below you can see a picture of my monitor.

I thought there was something wrong with my monitor and I feared I had to return it. However, I dared to do a bit of searching and, to my surprise,I learned that this problem is not as rare as I thought.

It happens on all kinds of monitors, from diverse manufacturers like Samsung, Asus or Acer. It happens on all kinds of AMD/ATI video cards, from the older AMD HD 4000 series to the newer AMD HD 6000 and 7000 series. Also, this problem is not specific only to a certain type of video output. You can encounter it when using both HDMI or DVI cables to connect the video card to the display. Then, the problem can be encountered both in Windows 7 and Windows 8 as well as when using multiple versions of Catalyst Control Center (CCC)..

The Culprit:The Scaling Setting for the AMD/ATI Video Output

AMD/ATI video cards have a scaling setting in their drivers, which tells the video card if it should resize the video output delivered to the display, or not. On some High Definition displays, especially when using the 1920 x 1080 resolution, the scaling is incorrectly set by the driver.

AMD drivers apply a default scaling value and they have a slider you can use to change it. Its extremities are named underscan and overscan:

• Overscan is when the image is shaved off by the display but not by the video card. This is not a problem of the modern world though. Only very old TVs and displays required overscanning because they used different technologies for displaying the image. Old means displays produced in the 1930s through 1970s.

  This meant that there were "non safe" areas on the screen where the image could be shaved off. Modern displays have integrated overscan and they now display what they receive as an input, pixel by pixel. Therefore, there is no danger of having the image shaved off. That's why video card drivers allow you to set the overscan only to 0 and not to higher values.

• Underscan is the exact opposite: the video card must constrain the size of what it sends over to the display, to counteract the overscan. When the image is underscanned, as it is the case here, it means that the video card doesn't correctly identify the display connected to it and its capabilities. It assumes there is a risk for the image to be cut off by the display. Therefore, it sets an underscan value of up to 15% to counteract the assumed problem.

The Fix: Change the Scaling Level to 0% Overscan

Since modern displays do not have an overscanning issue, there is no need for the video card to counteract this assumed problem by underscanning the video output sent to it.

To solve this problem, start by installing the latest AMD/ATI drivers for your video card and the operating system you are using. You will find them here: AMD Graphics Drivers & Software.

Open the AMD Vision Engine Control Center (or Catalyst Control Center as named in earlier versions of the product).

If you are using Windows 7, go to "Desktop and Displays -> My Digital Flat-Panels -> Scaling Options (Digital Flat-Panel)".

If you are using Windows 8, go to "My Digital Flat-Panels -> Scaling Options (Digital Flat-Panel)".

Take the Scaling Options slider and set it to zero.

Then, click or tap Apply and the problem is fixed. Here's how the image looked on my Asus monitor, after this change was made:

Much better, isn't it?

Conclusion

As you can see, the problem is not your monitor. There's no need to return it. The real problem is how the video card detects the monitor and its capabilities. If something goes wrong during this process, it sets the wrong scaling values to the video output being sent to the display. I hope that this tutorial helped in solving your problem.
