Selvtestfunktion

Bemærk

Inden du ringer for hjælp, så kør en selvtest for at se, om skærmen fungerer korrekt. Henvend dig til servicecenter med problemer, du ikke selv kan klare.

Kørsel af en selvtest

1.Sluk for både computeren og LCD-skærmen.

2.Fjern videokablet fra computerens bagside.

3.Tænd for LCD-skærmen.

Figuren vist herunder ("Check Signal Cable") vises på en sort baggrund, når LCD-skær- men fungerer normalt, selvom der ikke detekteres noget videosignal: I selvtesttilstand forbliver LED-strømindikatoren grøn, og figuren flyttes rundt på skærmen.

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

Hvis din LCD-skærm forbliver tom, når du har kørt en selvtest, så kontroller din video-con- troller og dit computersystem. Din LCD-skærm fungerer korrekt.

Advarselsmeddelelser

Hvis du indstiller din skærm til en opløsning og en opdateringsfrekvens, den ikke understøtter, vises meddelelsen herunder på din skærm i et minut. I dette minut skal du nulstille opløsnin- gen og opdateringsfrekvensen til en understøttet opdateringshastighed og opløsning. Hvis opdateringshastigheden er mere end 85 Hz, vil du se en sort skærm, fordi LCD-skærmen ikke understøtter en opdateringshastighed over 85 Hz.

Bemærk

Se under Specifikationer > Forudindstillede timertilstande for de opløsninger og frekvenser, som LCD-skærmen understøtter. Din LCD-skærm understøtter automatiske forudindstillede timertilstande.

Vedligeholdelse og rengøring

1) Vedligeholdelse af LCD-skærmkabinettet.

Rengør med en blød klud, når du har frakoblet strømkablet.
