The Optoma TX778W is a workhorse of a high-end projector whose Texas Instruments DarkChip3 DLP chipset with BrilliantColor cranks out more than 134 million colors at a brilliant 4300 ANSI lumens with a contrast ratio of 3000:1. Ironically, DLP chipsets not only produce some of the most intensely vivid and beautiful images of any technology, they actually save you time and money too. They don't require filters that have to be cleaned and replaced.Optoma Technology TX778W specs Image Display Projector Display System Single 0.7" DarkChip3 DLP Technology by Texas Instruments Native Resolution XGA (1024 x 768) Number of Pixels 786,432 Lumens Brightness 4300 ANSI Lumens Contrast Ratio 3000:1 Aspect Ratio 4:3 Native, 16:9 Compatible System NTSC, NTSC 4.43, PAL, B, D, G, H, I, M, N and SECAM B, D, G, K, K1, L HDTV Compatibility 720p, 1080i Lens System Lens F = 2.52-2.79; f = 22.55-27.06 Focus/Zoom Adjusting Manual/Manual 1.2x Lens Shift None Recommended Projection Size 31.2 to 313.5" Features Keystone Correction ±18° Vertical Ceiling Mountable Yes Rear Screen Projection Yes Projection Tilt Option ±16° Built-in Speaker 3 Watt Speakers x 2 Input/Output Connectors Input Terminals HDMI x 1DVI-D With HDCP x 1Composite x 1S-Video x 1Audio (For S-Video) x 1VGA x 2Audio (For VGA2 In Connector) x 1Audio Input Connector (For DVI-D Connector) x 1USB Connector (Connect to PC for Remote Mouse function) x 1 Output Terminals Audio Out x 1VGA-Out Connector (Monitor Loop-Through Output) x 1RJ45 (I/O) x 1RS232 x 1+12 Volt Trigger (To Control Screen Remotely) Control Protocol Detailed in User's Manual General Lamp (Bulb) 330W UHP Fan Noise 30 dB (STD) Remote Control IR Wireless With Laser Pointer and Mouse Function Power Requirements 100 – 240 V AC, 50/60 Hz Auto Switching Dimensions (WxHxD) 15.67 x 5.2 x 11.61" (398 x 132 x 295 mm) Weight 11.5 lb (5.2 kg)
