Dobrý den, v popisu projektoru máte technickou chybu jako prase! JVC DLA X7900B, (i modely X5900 a X9900) využívají k vytvoření obrazu technologii D-ILA a ne DLP!!! D-ILA je pokročilá technologie založena na třech odrazných (!) LCD panelech v základních barvách RGB - červený, zelený a modrý. Obraz z těchto tří panelů se pak opticky spojí a vytvoří klidný plnobarevný obraz. Tuto technologii firma JVC ve svých projektorech používá už velmi dlouho. Naopak DLP je poměrně levná technologie tvořena jediným (!) odrazným DMD panelem, jehož každý bod tvoří miniaturní elektronicky naklápěné zrcátko, které kmitá až 60000x za sekundu. Tím se tvoří požadovaná stupnice šedi a tedy ve výsledku všech bodů černobílý obraz. Barvy se pak tvoří předsazeným barevným rotujícím kotoučem obvykle se šesti průhlednými barevnými výsečemi (RGBRGB) a jak se kotouč otáčí a barvy se rychle střídají, vzniká díky setrvačnosti, tedy nedokonalosti lidského oka plnobarevný obraz. To je veliký rozdíl!
