   Using the CGP Touch's Fast Switch Feature
   ----------------------------------------------
   Some models of Stingray are shipped with the Fast Switch feature.
   The Fast Switch feature in the Picture Window utility allows you
   to switch screen resolution without restarting Windows.  You can use
   Fast Switch to flip between resolutions of the same color depth and
   resource size.

   Since Windows is not restarted, some applications may not redraw
   themselves properly because they don't monitor the change.  In
   this case, you can either restart these applications from scratch
   or restart Windows itself by using the Restart button within Picture
   Window.



   Fast Switch Limitations
   -----------------------
   Since the CGP Touch's Adjust utility deals with CRT timings,
   it must be closed completely before using the Fast Switch.

   You should also close all DOS windows (both full screen or
   windowed) before using Fast Switch.



   Video Acceleration
   ------------------
   (Stingray Pro/Video and Stingray 64/Video models only)

   To take advantage of the hardware scaling and filtering features of
   the Stingray Pro/Video and Stingray 64/Video, you must install
   Microsoft's Video for Windows 1.1D or later (earlier versions did not
   include the DCI compatiblity necessary to take advantage of
   hardware-based video acceleration).  We have included the runtime
   version of Video for Windows 1.1D with your Stingray/Video product.
   Make sure you install it after installing the operating software and
   the Windows display driver software.

   Here's a quick way to demonstrate Power Playback:
   1) Run Picture Window and select a 16-bit or 24-bit color mode.
   2) Install Video for Windows 1.1D. Place the diskette in a drive,
      select File/Run from Program Manager, and run SETUP.EXE from the
      diskette.
   3) Use the Power Preview or Power Player utilities in the CGP
      Touch to open a DCI-compliant video clip.
   4) Play the video clip using the Power Player.
   5) Enlarge the video clip by either dragging the video frame or
      clicking on the zoom button of the Player.
   6) Notice the speed and image quality. The video clip should
      continue to run in full speed.

   In general, the quality of the enlarged video image has a lot to
   do with the quality of its original size.  Naturally, if an image's
   original size is small and you enlarge it a great deal, there are
   not enough pixels to begin with to produce a good quality scaled
   image.

   You can use the following method to verify whether Stingray's video
   acceleration is enabled:
     Move the Windows cursor over an enlarged video window.  If the
     cursor automatically jumps to the edge of the video window, then
     video acceleration is enabled.



   Video Acceleration Limitations
   ------------------------------
   DCI capability is not available in the following cases:

   1) in any 4bpp (16 color) graphics mode.
   2) in any interlaced graphics mode.
   3) in the 1280x1024 8-bit and 1600x1200 8-bit graphics modes.
   4) when there is another object (dialog box, application, etc)
      covering all or part of the video playback window.
   5) when one dimension of the stretched video window is smaller
      than the original size.  For example, if you make the width
      larger, but the height smaller than original size, then DCI
      support is disabled.

   DCI capability may not run correctly in the following cases:

   1) in any BigMap (virtual desktop) modes.
   2) without closing the AVI file completely before using the
      Fast Switch feature. For example, if you use Microsoft's Media
      Player to open a video file, then use Fast Switch to switch
      to a new resolution, the DCI capability may not work in the new
      mode. You should close the video completely, including the Media
      Player that opened the file, before using Fast Switch.

   In general, play a video clip in a Windows 16-bit or 24-bit color
   mode in order to obtain the best quality.

   Not all video file (AVI) formats are supported by DCI under
   Video for Windows. AVI files using the following CODECs
   (COmpressor/DECompressor) are currently supported by DCI:

       Intel Indeo 3.1, 3.2
       SuperMac Cinepak
       Microsoft MSVideo 1.1 and above

   Other formats will run under Video for Windows, but may not have
   DCI support.

   The complete version of Microsoft's Video for Windows includes a
   utility called VidEdit which may be used to convert video clips from
   between formats.  VidEdit can be used to convert a clip compressed
   with a non-DCI CODEC to a compliant CODEC such as the ones listed
   above.  There may also be other third-party utilities which can do
   the same thing.
