Funktionskontrol ved selvtest

Bemærk

Din skærm indeholder en selvtestfunktion, med hvilken du kan kontrollere, om skærmen fun- gerer korrekt.

Funktionskontrol ved selvtest

1.Tænd for både computeren og skærmen.

2.Fjern videokablet fra computerens bagside.

3.Tænd for skærmen.

Hvis skærmen fungerer korrekt, vil du se en boks i illustrationen herunder.

Denne boks vises ved normal drift, hvis videokablet beskadiges eller ikke er tilsluttet.

4.Sluk for din skærm, og tilslut videokablet igen. Tænd herefter for både computeren og skærmen.

Hvis din skærm forbliver sort efter brug af den forrige procedure, skal du kontrollere din video- controller og dit computersystem. Din skærm fungerer korrekt.

Advarselsmeddelelser

Hvis der er nogen galt med indgangssignalet, vises en meddelelse på skærmbilledet, eller skærmbilledet bliver sort, selvom strømindikator- LED'en stadig lyser. Denne meddelelse kan indikere, at skærmen er uden for scanneområdet, eller at du skal kontrollere signalkablet.

Omgivelser

Placeringen af skærmen kan påvirke kvaliteten og andre af skærmens funktioner.

Hvis der er subwooferhøjttalere i nærheden af skærmen, skal du afbryde for subwooferen og flytte den til et andet værelse.

Fjern alle elektroniske enheder, som f.eks. radioer, ventilatorer, ure og telefoner, der er mindre end en meter fra skærmen.

Praktiske råd

En skærm omdanner de visuelle signaler, der modtages fra computeren. Hvis der er et prob- lem med computeren eller videokortet, kan dette derfor medføre, at skærmen bliver sort, har
