    Home theater with the projector in technical types are divided into three machine (CRT), single machine (DLP, LCD, such as D/ILA, LCOS) two kinds big. Three machine good color reproduction, high contrast ratio is almost infinite (15000:1), so you have to choose the white curtain, such as ST130 UM150 etc; Single machine due to contrast, color reduction is relatively poor, screen manufacturers a targeted research and development and manufacture of the gray screen, mainly due to improve the contrast and color reproduction of the single machine, such as the FIREHAWK, GREYHAWK RS etc. Single machine, of course, also can choose white screen projection cloth, but never can choose three machine gray projection screen cloth.
