The 16:9 image at 1,920 × 1,080 is equally suited to presentations and Full HD video. The low-maintenance light source runs for up to 20,000 hours, two HDMI inputs keep the presentation PC and video conferencing system permanently connected, and the serial RS-232 interface integrates the projector into room control systems.\u003c\/p\u003e\n\n\u003ch3\u003eKey benefits at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4,000 ANSI lumens in Full HD:\u003c\/strong\u003e slides, spreadsheets and videos remain clearly visible in 16:9 format even with the room lights on.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-maintenance light source:\u003c\/strong\u003e 20,000 hours in normal mode, up to 30,000 hours in Eco mode, service-free in continuous operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo HDMI inputs:\u003c\/strong\u003e presentation PC and video conferencing system stay permanently cabled at the same time – no replugging when switching sources.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRS-232 control:\u003c\/strong\u003e integrates the projector into media control systems via a serial interface and allows central operation without a network on the projector.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick alignment:\u003c\/strong\u003e automatic keystone correction (±40° vertical and horizontal) and 4-corner adjustment compensate for image geometry when the mounting position is not exactly at the centre of the screen.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWall colour correction:\u003c\/strong\u003e electronically compensates for coloured projection surfaces and delivers neutral colour reproduction even on yellow, green or blue walls.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs the BenQ LH655C the right choice?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eYes,\u003c\/strong\u003e for classic meeting, conference and training rooms up to around 150 inches that need a bright Full HD image in 16:9 for presentations and video from a standard distance, and where the projector should run with low maintenance in continuous operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot ideal\u003c\/strong\u003e if central network remote management via LAN is mandatory: the LH655C is controlled via the serial RS-232 interface and has no LAN port.

The 16:9 format reproduces presentation slides and Full HD video full-screen, without black bars. With the direct power-on function, the projector starts as soon as mains power is applied; signal power-on wakes it from standby as soon as a notebook connects via HDMI.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eTraining and seminar rooms\u003c\/strong\u003e\u003cbr\u003e\nIn training use, the LH655C starts immediately after switching on without a warm-up phase.

Auto keystone correction saves setup time when moving, and the light source needs neither warm-up time nor lamp changes.\u003c\/p\u003e\n\n\u003ch3\u003ePicture quality of the BenQ LH655C\u003c\/h3\u003e\n\n\u003cp\u003eThe 0.65\" DLP chip works together with the light source to reach 4,000 ANSI lumens at full brightness. In business use, the dynamic contrast ratio of 3,000,000:1 helps above all with fine lines, spreadsheets and dark chart areas. DLP technology renders a sharp pixel structure, which visibly helps with text slides, diagrams and spreadsheets. In 16:9, Full HD video fills the screen – relevant for training videos and video conferences.\u003c\/p\u003e\n\n\u003cp\u003eEco mode lowers the laser output with dark image content, reducing power consumption and noise down to 31 dB(A).
