The iH Display Driver spreads the Windows desktop across the screens connected to the iH cards.

Please follow the installation instructions in the iH Manual which can be found on the iH CD and on the Datapath web site at: www.datapath.co.uk.

Install the iH Display Driver by double clicking on install.exe.

Version 2.07 - 9^th November 2005

• Now clear frozen video from a Mosaic-SQ16 window when the video source is removed.
• Added MOSQEASY.DLL to the Mosaic-SQ16 driver. This implements the SDK interface for Mosaic-SQ16.
• Added MOSEASY.DLL to the Mosaic-SQ16 driver allowing applications written for Mosaic to work with Mosaic-SQ16.
• DirectShow filter now supports WMV files at HDTV resolutions.
• The Mosaic-SQ16 driver now works correctly with S-Video.
• Enabled triple buffering when using Mosaic-SQ16.
• Fixed PCI resource conflict on some motherboards.
• Provided error recovery for failed DMA operation on some motherboards.

Version 2.06 - 14^th September 2005

• Added beta driver for Mosaic-SQ16.
• Fixed a problem that prevented the TWIN tab appearing in the in the Advanced Display Settings Dialog when Data Execution Prevention (DEP) is enabled.

Version 2.05 - 28^th July 2005

• Added video gaps.
• Added a DirectShow Video Renderer which provides:
  • Accelerated video playback in Windows Media Player (version 9.0 or greater).
  • Accelerated DVD playback using PowerDVD 6.0 (requires DirectX 9 or later).
  • An accelerated renderer for use with the Vision RGB-PRO streaming driver.
  
  The DirectShow renderer may work with other DVD packages, though these are not tested or fully supported.
  Full screen playback requires the iH to be the primary monitor.
  DVD playback in Windows Media Player requires Windows XP and a suitable DVD decoder, i.e. PowerDVD.
• Fixed green line along left edge of screen.
• Fixed incorrect display of modes with horizontal blanking of 512 pixels or greater.
• Fixed problem selecting correct refresh-rate for non-VESA modes that have a choice of refresh-rates.
• Added support for desktop gaps to the right of the screen.
• Disable PCI VGA palette snooping if enabled by motherboard, fixes problem with colours.
• Fixed problem with device re-ordering when in Horizon compatible mode.
• Improved recovery from some detected errors.
• Fixed screen corruption problem when displaying accelerated RGB data at resolutions greater than 1280 pixels wide with video overlay not enabled.

Version 2.04 - 21^st December 2004

• Added new display modes: 1400x1050 60Hz at 16bpp & 32bpp.
• Fixed the display corruption that can occur when increasing the resolution with a software cursor active.
• Updated Mosaic driver to V0.23.
• Updated Vision Switch driver to V1.01.
• Fixed potential crash when installing the driver.
• Updated VisionSwitch-32 driver to V1.01.
• Fixed potential crash when installing the driver.

Version 2.03 - 10^th November 2004

• Fixed a problem where a video overlay would stop updating on the right side (overlay width 255 or 511 pixels).
• Custom display modes read from the Registry now have the correct sync-polarity.
• Fixed display corruption with custom modes that have zero-length horizontal front porch.

Version 2.01 - 11^th August 2004

• The driver has improved error logging and reverts to a single screen if a problem occurs during boot-up.
• Fixed problem that can occur when the iH card is not the VGA boot card, the symptom is erratic log-on.
• Added support for VisionTV tuner card(s) connected to master iH card.
• Now ensure that only analogue or digital output is enabled, never both.
• Fixed potential hardware cursor alignment problem.
• Now clear the video memory when the display mode is changed.
• Added new display modes:
  • 1020x765 60Hz
  • 1600x1200 30Hz (for VQS01)
• Fixed problem with desktop modes that are sub-multiples of larger single-screen modes e.g. 960x720 2x2 is 1920x1440.
• Fixed problem with video overlay and the VQS01 at 2048x1536. For best results also requires a firmware upgrade to the VQS01.
• Reduced the artefacts caused by capturing video overlay or Mosaic without pausing.
• Now allow a video switch with fewer outputs than the number of screens to be used. If a screen does not have a video switch output associated with it, it acts as though no video switch is present.
• If the video overlay driver is configured to use a video switch, it will reserve the first n outputs from the video switch (where n is the number of screens). This allows Wall Control or the Vision Switch stand alone application to be used to control the remaining outputs of the switch without affecting the video overlay.
• Updated Mosaic driver to V0.22:
  • Driver no longer crashes when upgrading a system with more than one device installed.
  • Driver now correctly enumerates screens under NT4.
• Updated Vision Switch driver to V1.00: Driver no longer crashes when upgrading a system with more than one device installed.
• Updated VisionSwitch-32 driver to V1.00: Driver no longer crashes when upgrading a system with more than one device installed.

Version 2.00 - 12^th May 2004

• Added support for display modes created from Monitor EDIDs and the Registry.
• Updated TWIN Property sheet.
• Improved Boot-up and mode-change performance.
• Can now specify use of analog or digital output if no Monitor EDID is detected.
• iH card does not have to be the VGA boot device anymore. Can use another VGA card as a control screen (see known problems below).

• If you have multiple iH cards installed, there is a check box labelled Extend my desktop onto this monitor in the Settings tab of the Display Properties dialog. If you check this box for any iH apart from the first and apply the changes, your system will display garbled graphics and become unusable.
• The cursor shadow causes a pink halo when over a video overlay window. This can be stopped by switching off cursor shadows.
• Under Windows XP, menu shadows causes a pink halo when over a video overlay window. This can be stopped by switching off menu shadows.
• Always close all the video overlay applications before performing any operation that modifies the resolution or bit depth of any attached display. Failure to do so could result in the machine locking up and requiring a reboot.
• If you change the offset of the iH driver's virtual screen on the desktop by changing the iH cards boot status then Windows may report the desktop offset to the driver incorrectly until the display mode has been changed in Windows. This can result in incorrect display of video or accelerated RGB data. To fix this, either reboot the machine or change the display resolution/refresh temporarily.
