NEC Multisync LT155 LCD Projector 1,200 Lumens. Used Condition With Cables And Carrying Case. ***NO REMOTE*** SKU GRG-A
Size. The LT155 is at this writing the smallest LCD projector on the market. Only 9.6" long and 8.2" wide, it is smaller than a standard notepad. And with a height of only 2.5" it can fit easily into any reasonable sized briefcase.
Light engine. The light engine consists of three 0.9" native XGA resolution LCD polysilicon panels and a 130-watt lamp. In its High-Bright mode, the system produces 1200 ANSI lumens of brightness. And if run in High-Bright mode exclusively the lamp has a 1000-hour life. However, you can choose to run in Eco-mode, which reduces the lumen output by 30%, but doubles the lamp life to 2000 hours. Most home theater users will want to operate the unit in High-Bright. But presenters will often find that the economy mode is more than adequate for a Powerpoint or Excel spreadsheet presentation to a small audience.
Inputs. The LT155 takes an impressive array of input signals. It accepts VGA through UXGA (1600 x 1200), compressing both SXGA and UXGA into its native XGA format. It accepts both interlaced and progressive component video, NTSC, PAL, SECAM, and NTSC 4.43, and HDTV (1080i, 720p, and 480p).
Aspect ratios include both 4:3 and 16:9. DVDs can be displayed in anamorphic format in cinema mode.
Digital keystone. There is a digital keystone adjustment to a maximum of 45 degrees upward and 15 degrees downward. The feature is quite usable for Powerpoint presentations. For detailed financial data, you will want to avoid aggressive keystone adjustments as they tend to blur some of the image detail. Home theater users interested in optimum video quality should never use this feature on this or any other projector.
Zoom lens. There is a manual zoom lens, but it has a very modest 1.15x zoom factor. In practical terms, that means the size of your projected image will be determined almost exclusively by the distance of the projector to the screen. The zoom will help you make slight adjustments to get the image to fit just right on a screen, but that's about it. Based on the focal length of the lens, a 60" diagonal (4:3) image can be thrown from 8.5 feet, and a 100" diagonal image requires a throw distance of 14 feet.
PC Card Reader. The LT155 has a small PC card reader that takes a CompactFlash memory card. A CompactFlash card holds 1/4 the volume of a standard PCMCIA card. So keep in mind that there is more of a file size restriction on this system that there is on larger projectors with standard PCMCIA readers. On the other hand, most projectors in this weight class don't have this feature at all.
Connection panel. The connection panel includes a mini 15-pin D-Sub for RGB and component video input, an audio input jack, an S-video and composite video jack, an 8-pin PC control port, a USB terminal and the card reader slot.
Auto-sense. The LT155 does what I wish many other projectors would do-it automatically senses the type of incoming signal that its getting adjusts accordingly. For example, when I flip the toggle switch on my DVD player from 480p to 480i, the LT155 recognizes the shift from progressive to interlaced, makes the adjustment and continues on with the display as if nothing happened. On many competing units one has to go into the menu and physically select the new signal format in order to get the projector to understand what's going on. For those who will be feeding a variety of computer and video formats into the VGA port, this is a very convenient feature.
On-screen annotations. For presenters who want to highlight and annotate the screen in real time during a presentation, the LT155 can do this but you must attach a USB mouse to accomplish it.
Audible noise. The manufacturer's spec indicates a 35 dB rating for audible noise, which is very quiet. However, the projector achieves this only in Eco-mode. In High-Bright mode the fan noise is more apparent. Overall it is not objectionable and may be described as low to moderate. The fan noise in High-Bright mode is fairly typical of machines in its weight class. For permanent home theater installation, users may want to install a sound damping enclosure or semi-enclosure to muffle its operation. This is all relative to one's sensitivity however. I watched several movies on the LT155 with the unit perched on a shelf three feet behind my head. Most of the time I was not conscious at all of the fan noise even from that distance.
Audio. There is a single 0.5 watt speaker on board.
