DVI2USB 3.0 Release Notes
Epiphan Video is happy to announce release 3.30.2 for DVI2USB 3.0. This maintenance release includes the
following updates.
Updated default EDID
DVI2USB 3.0 now has better interoperability with digital video cameras thanks to an updated default EDID.
Improved power management
Power management improvements mean that DVI2USB 3.0 now supports a wider range of USB host
controllers.
Online help
DVI2USB 3.0 now has searchable online HTML help. Choose your video grabber from the Epiphan support
page for a link to online help.
Improved audio support (Windows and Linux only)
DVI2USB 3.0 now has the ability to perform audio resampling and has cleaner audio at all frequencies.
Additionally, support is added for 44.1kHz and 32 kHz audio over HDMI.
Windows 10 support and updated signing process (Windows)
Epiphan drivers are supported on Windows 10, using SHA-2 signing. Upon moving to this new signing
mechanism, we have dropped support for older platforms Windows XPand Windows Vista. If you're using
Windows 7, ensure it is up to date to support with drivers signed with SHA-2.
Resolved issues
Among numerous small bug fixes and tweaks, this firmware and driver release for DVI2USB 3.0 fixes the
following important issues found in earlier releases or Beta releases.
lImproved Mac OS support through use of new signing keys. As a result, it's also no longer necessary to
turn on security settings permitting application installation for apps downloaded from "Anywhere"
before installing the Epiphan software package.
lImproved video and audio capture, resolving an issue where capture was occasionally unstable when
capturing signals that include embedded audio.
Limitations and Known Issues
This section includes known issues or limitations that affect functionality or usability and ways that you can
work around these limitations.
lVideo grabber may not be recognized by the system after reboot. This problem affects Mac OS more
than Windows or Linux.
Workaround: Physically disconnect the video grabber from the computer's USBport and reconnect it.

If this workaround poses a problem for your specific use case, consider purchasing a new DVI2USB 3.0;
a hardware update resolved this problem permanently for devices with serial number 358800 and
higher.
lCapturing HDMI sources with Adobe RGB 32 color space (argb32) can cause image corruption.
Workaround:If you see image corruption with this color space, switch to another color space.

DVI2USB 3.0 User Guide What is DVI2USB 3.0?
What is DVI2USB 3.0?
DVI2USB 3.0™ is Epiphan's professional-series external DVI-I video grabber. In a nutshell, it captures images
and video from VGA, HDMIand DVI-I video sources and digitizes them on your laptop or workstation via
connection to a USB 3.0 port.
The video capture workstation can record and/or stream the resulting uncompressed diagnostic-quality
images and videos. On Windows, both audio and video capture is supported for HDMI sources. Thanks to
EpiphanVideo capture technology, this small, portable product connects directly to your computer's USB 3.0
port - no need for a large workstation with a free peripheral component interface (PCI) slot.
DVI2USB 3.0 captures video and audio from any single link DVI, unencrypted HDMI, or VGA source. Meeting
greater demands for transferring larger files at faster speeds, this external video grabber supports USB 3.0
technology, capable of transferring uncompressed data with speeds of up to 5.0 (Gbits/s) - about ten times
faster than USB 2.0.
In practice transfer speeds are dependent on factors such as USB load and hardware
configuration.
DVI2USB 3.0 is versatile and can be used with multiple workstation configurations. It is backward compatible
with USB 2.0 connections, however it transfers video at a reduced frame rate when using USB 2.0.
Using the included Epiphan Capture Tool, DVI2USB 3.0 captures full 1080p HD at 30 frames per seconds and
supports resolutions up to 1920×1200. When working with third-party software, such as Windows Media
Encoder with YUV 4:2:0 chroma sub-sampling, 1080p video is captured and recorded 60 frames per second.
For more information about maximizing the frame rate when capturing, recording and streaming video using
third-party applications, refer to the How to Record Video using Window Media Encoder tutorial on Epiphan’s
website.

DVI2USB 3.0 User Guide What is DVI2USB 3.0?

QuickTime in Mac OS.This means you can use it with a number of different third party applications for
capturing, recording and streaming video.
DVI2USB 3.0 is part of Epiphan’s complete line of video and audio signal capture products. For more
information about all Epiphan’s video signal capture products, refer to the USB Video Grabbers page on the

source and video grabber in any order.
1. Connect the video source to the DVI-I port on the video grabber. (If necessary, use an adapter or
appropriate converter cable.)

DVI2USB 3.0 User Guide Quick start
If using a splitter cable for your video source, use a high-quality HDMI or DVI splitter to split the
signal between an other devices and the video grabber. For VGA signals, use an active VGA splitter
rather than a passive VGA splitter (also called a Y-Adapter). This will help maintain a cleaner video
signal.
Capture video
If needed, read Epiphan Capture Tool (Windows) or Epiphan Capture Tool (Mac) for information on how to
launch the capture tool.
1. Start the Epiphan Capture Tool; your video source is immediately detected (if you see a No Signal
