Dot Pitch, Lodret Frekvens, Plug & Play

Ordforklaring

Dot Pitch

Skærmbilledet er sammensat af røde, grønne og blå punkter. Jo tættere punkterne står, des højere er opløsningen. Afstanden mellem to punkter af samme farve kaldes 'Dot Pitch'. Enhed: mm.

Lodret Frekvens

Skærmen skal kaldes frem flere gange hvert sekund for at danne og vise et billede for brugeren. Frekvensen af denne gentagelse per sekund kaldes Lodret Frekvens eller Gentagelsesfrekvens. Enhed: Hz.

Eksempel: Hvis det samme lys gentages 60 gange pr. sekund, betragtes det som 60 Hz.

Vandret Frekvens

Den tid, det tager at scanne én linje, der går fra højre kant til venstre kant af skærmen vandret, kaldes den Vandrette Cyklus. Det inverse tal for Vandret Cyklus kaldes Vandret Frekvens. Enhed: kHz.

Interlace og Non-Interlace Metoder

Når skærmens vandrette linjer fra top til bund vises i rækkefølge, kaldes det Non-Interlace metode, mens det kaldes Interlace metode, når lige og derefter ulige linjer vises. Non-Interlace metoden anvendes for de fleste skærme for at opnå et klart billede. Interlace metoden er den samme metode, som anvendes for TV.

Plug & Play

Dette er en funktion, som giver den bedst mulige skærmkvalitet for brugeren ved at gøre det muligt for computer og skærm automatisk at udveksle informationer. Denne monitor opfylder den internationale standard VESA DDC for Plug & Play funktionen.

Opløsning

Antallet af vandrette og lodrette punkter, der anvendes for at danne skærmbilledet, kaldes 'opløsning'. Dette tal angiver billedets nøjagtighed. Høj opløsning er velegnet for multi-tasking, idet skærmen er i stand til at vise flere billedinformationer.

Eksempel: Hvis opløsningen er 1680 X 1050 betyder det, at skærmbilledet er sammensat af 1680 vandrette punkter (vandret opløsning) og 1050 lodrette punkter (lodret opløsning).

S-Video

Forkortelse for "Super Video." S-Video tilbyder på til 800 linjers vandret opløsning, hvilket giver video i høj kvalitet.

External Device Input (Eksternt enhedsinput)

External device input refererer til videoinput fra eksterne videoenheder, f.eks. video- eller dvd- afspillere, som er adskilt fra en tv-udsendelse.

DVD

En type digital diskteknologi, der kun medtager fordelene ved CD og LD, til at implementere en høj opløsning/kvalitet, hvilket giver brugeren mulighed for at få tydeligere billeder.

For bedre billede

1.Juster computer-opløsningen og skærmens strålehastighed (opdateringsfrekvens) som beskrevet nedenfor for at opnå den højeste billedkvalitet. Skærmens billedkvalitet kan være
