DVI2USB 3.0 is compatible with both a USB 2.0 and a USB 3.0 (SuperSpeed) USB interface. Note that performance, when in USB 2.0 mode, can be reduced.

USB 3.0, also known as SuperSpeed, comes standard on all computers manufactured after 2011. Check with your computer or motherboard manufacturer to verify that USB 3.0 is present on your system.

It depends on the resolution of your screen, the screen refresh rate, your operating system and the speed of the computer that is capturing images. Consult Specifications for appropriate capture rates.

No. DVI2USB 3.0 captures and transfers every pixel of the original frame in RGB24 format. In this respect, DVI2USB 3.0 provides better quality than a DVI-to-video converter paired with a Composite or S-Video grabber.

No. Unfortunately, some of these systems have poor support or no support at all for USB 3.0.

Yes. You may add custom modes through the DVI2USB 3.0 software, available as a free download.

The Linux drivers are available. Please contact us before you purchase if you require a driver compiled for a specific kernel version or kernel setting.

Yes, the DVI2USB 3.0 application has the ability to save captured signals as an AVI file.

The choice of codec and codec settings depend on the requirements for the quality of the AVI. You may need to try several codecs with different settings to see which codec best fits your task.

DVI2USB 3.0 has an automatic algorithm that crops visible images from the DVI frame. The algorithm may make a mistake, and be off by a few pixels. Please refer to Configuring Image Adjustments in section 18 of the Video Grabber User Guide.

Yes you can connect two or more DVI2USB 3.0 devices and capture multiple signals simultaneously. You will need to run the DVI2USB 3.0 application for each DVI2USB 3.0 device attached.

The DVI2USB 3.0 frame grabber works by emulating a high resolution video camera for Windows. DVI2USB 3.0 is a DirectShow compatible device, which means that virtually any video capture software designed for Windows is compatible with DVI2USB 3.0. For example, VirtualDUB can be used to record .avi files, Microsoft Media Encoder to record .wmv files, and RealProducer to record .rm files. DVI2USB 3.0 also supports Video4Linux in Linux operating systems.

No. DVI2USB 3.0 devices do not use frame compression, resulting in a high quality of the output.

DVI2USB 3.0 is no longer supported on Mac OS. However, you can still download older Mac firmware from the DVI2USB 3.0 download page.

Yes. DVI2USB 3.0 can capture unencrypted images and video from BNC/component, DisplayPort, Mini DisplayPort, and Thunderbolt outputs. In order to capture video from these formats, the appropriate converter cable must be purchased separately. Epiphan does not guarantee results when using third party cables.

Yes. You may capture both the video and audio from an HDMI signal using a HDMI-DVI converter cable, included in the box. Note that DVI2USB 3.0 cannot capture a protected or encrypted HDMI signal.
