Main Features

Based on a high-quality, new image compression system from the application of VQ (Vector Quantization) Technology along with high-speed coding/decoding technology from the use of the Linux operating system plus wireless network technology (IEEE802.11b), Sharp developed the Image Capturing System as a fundamental concept of wireless projector. Thus, the PG-M25X allows smooth realtime presentations without tedious cable connections. Enabling communications between multiple PCs and a single projector, or a PC and multiple projectors, this projector is ideal for all types of meetings, from project brainstorming to product presentations.

·	Wireless LAN eliminates tedious RGB cable connection setup between PC and projector.
·	Up to 250 PCs can be connected to a single projector and can be preset for group presentations. The PG-M25X projects images in the order that the PCs transmit images to the projector*. When transmitting data from multiple PCs to a projector using a conventional system, cables must be switched each time data is required from a different PC. The PG-M25X alleviates this by performing the switching internally. With a series of presenters lined up, just the touch of a key changes between data PCs to facilitate seamless multiple presentations. The result is smooth, speedy meeting and enhanced interactive communication.
·	Up to 4 projectors can be driven simultaneously from a single PC. To achieve this with a conventional system would require RGB cable connections between each projector setup. The PC wireless LAN replaces that with simple placement and presentation setup.
·	Two wireless LAN Cards are included.

* Transmitting data from multiple PCs at the same time may cause communication interference.

1. Any image displayed on the PC can be projected wirelessly in realtime.

·	Any application software such as PowerPoint, Excel and Word that runs on the Windows operating system can be displayed.
·	Mouse cursor movement can be also displayed.
·	Thus, even the meeting minutes you are creating on the spot can be also displayed in realtime.

2. High quality images can be quickly displayed within approximately 2 to 4 seconds (with a XGA data image display) thanks to the VQ data image compression system.

3. Provides quasi-animation effects (1 to 5 frames/sec.)

4. Residential software on the PC automatically sends the image data to the projector and the presenter does not need to send it each time, thus enabling a smooth presentation.


JPEG Format		JPEG 2000 Format		VQ Compression

Sharp, Tohoku University, and SIPEC Corp. jointly developed the innovative VQ (Vector Quantitization) image compression technology in order to realize a high quality, realtime image transmission system for a wireless LAN. Generating no mosquito noise (unavoidable with JPEG or JPEG2000) as well as reducing block noise, the VQ still image compression technology provides clearer projection images than JPEG or JPEG2000 with a PSNR (Peak Signal to Noise Ratio) improvement of 5 to 10 dB, especially for characters.

With memory card compatibility, the PG-M25X runs an auto-demonstration and auto-slideshow without a PC. Convert presentation materials made from PowerPoint, for example, into compressed VQ (Vector Quantization) still images*¹ and save in a Flash Memory Card. Or record still images taken by digital cameras or other devices in JPEG format, TIFF or BMP in a Flash Memory Card and then put the card into the PG-M25X PCMCIA Type II Card Slot.
The PG-M25X performs presentations automatically even without a PC, ideal for store demonstrations and auto-demonstrations in exhibitions and shows.

Compatible Flash Memory Card

	1 Supplied application software “Slide Manager” needed to convert presentation materials into VQ still images. 2 PC card adaptor needed to use these media.



	Next-Generation RF Gyro Wireless Remote Control (PG-M25X) Sharp has developed an RF-based wireless remote control incorporating U.S. Gyration Inc.’s original GyroPoint Technology™. Its unique features, including superior pointing (gesture tracking) function, operation flexibility with long distance capabilities and non-directivity, along with the omni-directional multiple remote control, give even greater convenience to your presentations as well as provide much more versatile presentation possibilities.


	Superior Pointing (Gesture Tracking) Function When you move your hand while holding a Gyro Remote, the remote accurately tracks your hand motions, indicating the screen with presentation tools such as the screen pointer, stamp and drawings, as well as controlling the PC cursor to navigate projector menus.


	Operation Flexibility Ordinary infrared remotes can control an object in a limited direction, such as 30° vertically, 45° horizontally, and only within the short distance of 7 metres. The next-generation Gyro Remote has no control direction limitations, providing a full 360° of control up to 18m. You can control the PG-M25X from any direction, even when a considerable distance from the projector.


	Newly-Developed, Ergonomically-Designed Remote Control (PG-M20X/M20S) In addition to perfectly fitting your hands, the newly-developed ergonomically-designed remote control with multiple direct buttons provides much easier controls for presentations at your command.

Slim, Lightweight and Compact Design from Sharp Original Straight Optical System

With the DLP™ system and Sharp’s original straight optical engine, the PG-M25/M20X/M20S achieves an amazingly slim (7.6cm), lightweight (2.6kg) and compact (4.2 litre) body. Bring it with your mobile notebook PC anywhere your business takes you.

Sharp's Original Straight Optical System

Sealed Optics

The optical mechanism of DLP™ system projectors is sealed in its structure, preventing dust, dirt and smoke from entering the body to a much greater degree than with LCD projectors. This enables longer use and reduces maintenance costs. These projectors are ideal for schools or other educational and training facilities, or for entertainment and leisure establishments such as sports bars or karaoke bars.

High Brightness and High Contrast

The new 12° DMD™ chip has a wider tilt angle than conventional chips, providing significantly improved optical efficiency and excellent contrast ratio. Plus, the DDR (Double Data Rate) DLP™ Engine together with the newly developed air bearing motor achieves 3x colour wheel rotation speed, reducing colour breaking phenomena common with previous generation DLP™ projectors.

Advanced Intelligent Compression

Higher resolution pictures can be compressed while keeping high quality to fit into the panel resolution.

Enhanced Up-Scaling

Lower picture resolutions can be up-scaled to the high image quality of projector panels.

DTV/HDTV and DVD Compatible

The PG-M25X/M20X/M20S provides high-quality images from DVD, HDTV and DTV (480P, 720P, 1080l with 4:3 and 16:9 aspect ratios) by receiving RGB signals and component signals (Y, PB, PR).

4-Position Gamma Correction

Gamma is an image quality enhancement function that offers a richer image by brightening the darker portions of the image without altering the brightness of the brighter portions. Four preset Gamma values (STANDARD, PRESENTATION, CINEMA and GAME) can be selected to allow for references in the images displayed and in the brightness of the room.

New Progressive Mode

The Progressive Mode of the previous I/P Conversion still had jagged lines and unclear images. The new Progressive Mode compensates for this interference, to provide a natural and smooth picture in the progressive mode.
