  • HD capture for each channel up to 1080P at 60 frames per second, HDMI capture up to 1080p and DVI up to 1920×1200
  • High performance DMA to system memory or direct to graphics memory with scatter gather
  • On board processor for real time mode and sink detection
  • Dynamic input source selection
  • Administrator mode


The XtremeRGB-Ex2+ has two complete capture channels supporting up to 1920×1080 DVI or 2048×1536 Analog resolution.
The XtremeRGB-Ex2+ captures the Analog/DVI data and triple buffers it into onboard storage. This data is then copied using DMA to the host system for display, storage or streaming.

When a EMS graphics card is used, the XtremeRGB-Ex2+ transfers the data directly to the graphics card thereby increasing performance. The XtremeRGB-Ex2+ sends the relevant portions of each captured image to each display channel and instructs each channel to use its graphics engine to render the data. This fully utilises the hardware and dramatically increases performance.

The XtremeRGB-Ex2+ is an ideal solution for applications that require the capture of Analog or DVI sources in real time.

Typical applications include:
• Viewing Analog or DVI sources from PCs, MACs, Industrial/medical equipment, cameras and other video equipment
• Streaming video applications
• Video/Data Wall Controllers

PCI Express
RGB 2048×1536
HD 1080p
HDMI 1080p
DVI – 1920×1200

When the RGB/DVI data is displayed on a non EMS graphics card, the XtremeRGB-Ex2+ sends the data to system memory or direct to the graphics card, dependent on the software used for display.


For streaming applications, the XtremeRGB-Ex2+ can be used with Windows Media Encoder to compress and stream captured video. To replay the video, use Windows® Media Player.

Any application compatible with Windows® DirectShow technology can use the XtremeRGB-Ex2+ due to its built-in WDM support.


The XtremeRGB-Ex2+ is supplied with a powerful software application for configuring the timing and format of the input sources and displaying the data. Simply connect your external DVI or Analog source into the card, run the XtremeRGB-Ex2+ application to automatically detect the video source format and display the captured video in a window on your desktop.
