Sawubona.
Uma ukwazi ukubekezelela amaphutha amaningi nezinkinga kwikhompyutha, khona-ke awukwazi ukubekezelela iziphambeko esikrinini (imivimbo efanayo njengasesithombeni ngakwesobunxele)! Aziphazamisi kuphela isibuyekezo, kepha zingonakalisa umbono wakho uma usebenza isikhathi eside isithombe esinjalo esikrinini.
Imivimbo esesibukweni ingavela ngenxa yezizathu ezahlukahlukene, kepha imvamisa ihlotshaniswa nezinkinga ngekhadi levidiyo (abaningi bathi kwavela izingcweti ekhadini levidiyo ...).
Ngaphansi kwezingcweti ziyaqonda noma ikuphi ukuhlanekezela kwesithombe kuqapha le-PC. Kaningi, ziyizimbangi, ukuhlanekezela imibala, imivimbo enezikwele kuyo yonke indawo yomqaphi. Ngakho-ke wenzani ngabo?
Masinyane ngifuna ukwenza ukubhuka okuncane. Abantu abaningi badida izinto zakudala ekhadini levidiyo ngamaphikseli aqhekekile eqapha (umehluko osobala okhonjisiwe ku-Fig. 1).
I-pixel efile ichashaza elimhlophe esikrinini elingashintshi umbala lapho isithombe esikrinini sishintsha. Ngakho-ke, kulula ukuthola, ugcwalisa isikrini ngemibala ehlukile.
Ama-Artefacts yi-distortions kusikrini sokuqapha engahlobene nezinkinga zomqaphi uqobo. Kumane nje ukuthi ikhadi levidiyo lihambise isiginali ehlanekezelwe (lokhu kwenzeka ngezizathu eziningi).
U-fig. 1. Izicucu ekhadini levidiyo (kwesobunxele), ipikseli ephukile (kwesokudla).
Kukhona izinto zakudala zesoftware (ezihambisana nabashayeli, ngokwesibonelo) nehadiware (ehlotshaniswa nehardware uqobo).
Ama-Software Artifacts
Njengomthetho, avela uma uvula noma yimiphi imidlalo ye-3D noma izinhlelo zokusebenza. Uma unezinto zakudala lapho kulayishwa iWindows (naku-BIOS), kungenzeka ukuthi usebenzelana kakhulu nayo izinto zobuciko (mayelana nabo ngezansi esihlokweni).
U-fig. 2. Isibonelo sobuciko bomdlalo.
Kunezizathu eziningi zokubonakala kwezinto zobuciko kulo mdlalo, kodwa ngizohlaziya ethandwa kakhulu yizo.
1) Okokuqala, ngincoma ukubheka izinga lokushisa lekhadi levidiyo ngesikhathi sokusebenza. Into ukuthi uma izinga lokushisa selifinyelele kumanani abucayi, khona-ke konke kungenzeka, kusuka ekuhlanekeni kwesithombe esikrinini, futhi kugcina ngokuhluleka kwensiza.
Ungafunda ukuthi ungalithola kanjani izinga lokushisa lekhadi levidiyo esihlokweni sami esedlule: //pcpro100.info/kak-uznat-temperaturu-videokartyi/
Uma izinga lokushisa lekhadi levidiyo lingaphezu kokujwayelekile, ngincoma ukuthi uhlanze ikhompiyutha kusuka othulini (futhi unake ngokukhethekile ikhadi levidiyo lapho uhlanza). Futhi unake ukusebenza kwama-coolers, mhlawumbe amanye awo awasebenzi (noma ahlanganiswe ngothuli futhi awashintshi).
Ngokuvamile, ukushisa ngokweqile kwenzeka ehlobo elishisayo. Ukuze wehlise izinga lokushisa lezinhlaka zohlelo lweyunithi, kunconywa ukuthi uvule ngisho nesembozo sendawo bese ubeka fan ejwayelekile phambi kwayo. Indlela yokuqala enjalo izosiza ukunciphisa kakhulu izinga lokushisa ngaphakathi kwephiko lesistimu.
Ungayihlanza kanjani ikhompyutha yakho kusuka othulini: //pcpro100.info/kak-pochistit-kompyuter-ot-pyili/
2) Isizathu sesibili (futhi kaningi ngokwanele) abashayeli bekhadi levidiyo. Ngithanda ukuqaphela ukuthi abashayeli abasha nabadala abanikezeli isiqinisekiso somsebenzi omuhle. Ngakho-ke, ngincoma ukuthi ngivuselele umshayeli kuqala, bese (uma isithombe sisekubi) Roll back umshayeli noma faka esidala kakhulu.
Kwesinye isikhathi ukusetshenziswa kwabashayeli "bakudala" kunesizathu esizwakalayo, futhi ngokwesibonelo, bangisizile kaningi ukujabulela umdlalo othile owenqabile ukusebenza ngokujwayelekile ngezinhlobo ezintsha zabashayeli.
Ungayivuselela kanjani umshayeli ngokuchofoza oku-1: //pcpro100.info/obnovleniya-drayverov/
3) Vuselela i-DirectX ne .NetFrameWork. Akukho lutho olukhethekile ongabeka amazwana kulo, ngizokunika izixhumanisi ezimbalwa ezihlokweni zami ezedlule:
- Imibuzo ethandwayo ngeDirectX: //pcpro100.info/directx/;
- .NetFrameWork ukubuyekeza: //pcpro100.info/microsoft-net-framework/.
4) Ukuntuleka kokusekelwa kwama-shaders - cishe kuzonikeza ubuciko esikrinini (izithunzi - Lolu uhlobo lwesikripthi sekhadi levidiyo elikuvumela ukuthi usebenzise okwahlukahlukene okuhlukahlukene. imiphumela emidlalweni: uthuli, i-ripples emanzini, izinhlayiya ezingcolile, njll., yonke into eyenza umdlalo ubhekane namaqiniso).
Imvamisa, uma uzama ukuqala umdlalo omusha ekhadini levidiyo elidala, kunikezwa iphutha lapho kuthiwa alixhasiwe. Kepha kwesinye isikhathi lokhu akwenzeki, bese umdlalo uqhubeka ekhadini levidiyo elingasekeli izithunzi ezidingekayo (kukhona nama-emadators akhethekile we-shader asiza ukwethula imidlalo emisha kuma-PC amadala).
Kulesi simo, udinga nje ukutadisha ngokucophelela izidingo zesistimu yalo mdlalo, futhi uma ikhadi lakho levidiyo lidala kakhulu (futhi libuthakathaka) - khona-ke, njengomthetho, akukho lutho oluzokwenziwa (ngaphandle kwe-overulsing ...).
5) Lapho wenza amakhadi wevidiyo ngokweqile, kungavela izinto zakudala. Kulokhu, setha kabusha amaza futhi ubuyise yonke into kusimo sayo sokuqala. Ngokuvamile, ukweqisa ngokweqile kuyisihloko esiyinkimbinkimbi, futhi ngendlela engenakhono - ungakhubaza idivaysi kalula.
6) Umdlalo we-buggy nawo ungadala ukuphambuka kwesithombe esikrinini. Njengomthetho, ungathola ngalokhu uma ubheka imiphakathi ehlukahlukene yabadlali (izinkundla, amabhulogi, njll.). Uma kunenkinga enjalo, uzohlangabezana nayo hhayi wena wedwa. Impela, endaweni efanayo bazovusa isixazululo kule nkinga (uma ikhona).
Izinto zobuciko be-Hardware
Ngaphezu kobuciko besoftware, kungahle kube nezingxenye zekhompiyutha, imbangela yazo zingasebenzi kahle i-Hardware. Njengomthetho, kuzodingeka ukuthi zibukwe yonke indawo, noma ngabe ukuphi: ku-BIOS, kudeskithophu, lapho kulayishwa iWindows, emidlalweni, noma ikuphi ukusetshenziswa kwe-2D ne-3D, njll. Isizathu salokhu, kaningi, ukuthathwa kwe-chip yehluzo, esikhathini esiningi kunezinkinga zokushiswa kwe-chip memory.
U-fig. 3. Izicucu ezikwi-desktop (iWindows XP).
Ngobuciko be-Hardware, ungenza okulandelayo:
1) Faka esikhundleni i-chip ekhadini levidiyo. Kuyabiza (maqondana nezindleko zekhadi levidiyo), kungumbango ukufuna ihhovisi elizolungisa, kuthathe isikhathi eside ukubheka i-chip efanelekile, njll. Izinkinga. Akwaziwa ukuthi uzokwenza kanjani lokhu kulungiswa ...
2) Ukuzama ukufudumeza ikhadi levidiyo. Lesi sihloko sibanzi. Kodwa ngizosho khona lapho ukuthi uma ukulungiswa okunjalo kusiza, ngeke kusize isikhathi eside: ikhadi levidiyo lizosebenza kusuka ngesonto kuye kwengxenye yonyaka (kwesinye isikhathi kuze kube unyaka). Mayelana nokufudumala kwekhadi levidiyo, ungafunda kulo mbhali: //my-mods.net/archives/1387
3) Ukushintsha ikhadi levidiyo nelisha. Inketho esheshayo futhi elula kunazo zonke, lapho wonke umuntu eza khona maduze lapho kuvela izinto zobuciko ...
Konke lokho kimi. Bonke bane-PC enhle namaphutha amancane 🙂
