Overview

The VPH-G90U is truly the "Flagship" model in CRT projectors. With its new high resolution 9" electromagnetic focus CRT, the VPH-G90 achieves incredible brightness and resolution output of up to 350 ANSI lumens (1300 peak lumens) and 2500 x 2000 pixels respectively. Also comes with a 3-line comb filter and a 3D-comb filter, which are selectable. Incorporates Sony's Digital Reality Creation (DRC), generating 4x the resolution from conventional video signals. It generates roughly the equivalent of a 960 line progressive scan image from NTSC video.

Features

• High Brightness and High Resolution Capability
  From the use of a new 9" electromagnetic focus CRT. The CRT of the VPH-G90U incorporates an ultra-fine phosphor, a low capacity gun and new magnetic coil to produce a spot size that is very crisp. Also incorporates a new high voltage circuit, new video decoder circuit and HACC lenses to provide the highest contrast, sharpest and most brilliant image ever from a Sony CRT projector. Together these technologies contribute to deliver 350 ANSI lumens (1300 peak lumens) and a maximum resolution of 2500 x 2000, ensuring the best possible image quality on screen.
• Accepts a Wide Range of Signals
  Providing the flexibility for the VPH-G90U to perform in a corresponding wide range of applications. Composite video, Y/C video, Component (Y/R-Y/B-Y), RGB and HDTV signals can be accepted and displayed. The projector will accept and display signals with horizontal frequencies up to 150kHz and has 135MHz bandwidth to ensure faithful reproduction.
• Selectable Comb Filters
  One 3-line and one 3D are provided for use with NTSC. The 3-line filter is best for video images with motion. The 3D filter is better for use with static images, eliminating more of the cross color and dot interference from such images. Together they ensure the best possible display of NTSC signals.
• Hexapole (6 Pole) Adjustment Function
  For more precise beam spot shaping in the corners of the image. This allows for a good focused, crisp image from corner to corner.
• Normal Defocus Mode
  Provided to deliver the best whites possible in the image. This mode can be shut off by user. When on, it will help ensure clean whites and high contrast.
• Auto Backround (ABG) Function
  This feature helps to maintain good black balance. The white line that would be present with ABG in earlier Sony CRT projectors will now be eliminated after 20 minutes from the time the unit is first powered on. Even though the line will be gone, the ABG will still function to improve image quality. ABG can be linked with other VPH-G90U projectors.
• New Registration Functions
  Incorporated into the VPH-G90U in order to make setup and adjustment easier and more accurate. Keystone and Pincushion adjustments, along with a fine adjustment mode, for Size, Linearity, Skew and Bow.
• 13 Original Memory and 137 Custom Memory Input Structure
  Provided so that the VPH-G90U can be configured for almost any need. Also, Input Memory Manual Load, Save, Delete and Protect functions have been added for installers, to make system integration and setup easier.
• CRT Burn-In Protection
  Provided in the form of a picture orbiting function for applications with a majority of stagnant images, and in the form of a scan line shift function. The brightness output of the VPH-G90U is so high that scan line burn-in with video images is a possibility. Scan line shift works to prevent that problem. Along with picture orbiting function, it helps provide longer useful CRT life. The picture orbiting function can also be synchronized between multiple VPH-G90U projectors.
• White Balance Selection
  For glass beaded screens and matte white screens. Selectable to tailor the VPH-G90U output to the screen being utilized, to obtain the best possible image quality. Also, the VPH-G90 has the ability to store white balance data for each input memory. Has 4 preset color temperatures of 9300/6500/5400/3200, and white balance can also be set to any user-desired level, as well.
• Index Function
  Is available in two levels. Device index is the number for each device (projector or switcher). Group index is organized from arbitrary user defined device indexes. The group index can be selected from the Remote Commander unit and will control all the devices in a specified group.
• Easy Polarity Change
  There is a separate polarity cover. When this cover is opened, the power of the projector is automatically turned off, if it hadn't been turned off already. All polarity changes for switching between desktop, ceiling and rear use can be made with sliding switches. No more need for rotating connectors.
• The Advanced Scheimpflug Adjustment
  Can be accessed just by opening the upper cover of the projector. No need to remove the entire cover. Scheimpflug adjustment can be made independently for each CRT while monitoring the on-screen test pattern image. These features contribute to quick, easy and accurate setup.
• Communication Systems (RS-232C/RS-422A/PJ COM RS-485)
  Available standard on the VPH-G90U to yield the ultimate in system integration with full function remote manual and automated control. The PJ Com RS-485 compliant port greatly enhances system integration opportunities by allowing simple daisy chaining and intelligent mutual communication between the projector, the switcher - if present - and any connected computers.
• Simulation Mode
  A new mode for a greater range of registration data adjustment for simulation and virtual reality applications. This allows for use of the VPH-G90U on curved or spherical screens.
• Full Function Wireless Remote Unit
  The RM-PJ1001 is a standard accessory for convenient control of the projector with a back light and direct access keys for many of the projector's features
