If those don’t work, we can create a custom one for you. If you ever run into such a problem, contact us at support, we have some other EDIDs that we will share.

As we discover these cases, we update our default EDID with the needed pieces but new cameras come out every month and some of those could suffer from a similar issue. We find that in these cases the camera is looking for something very specific in the EDID and our default EDID, designed to address a wide variety of devices, does not have this. HDMI CamerasĮvery now and then I hear about an HDMI camera connected to one of our products and we are either capturing nothing or only standard definition resolution video from the camera. This is because even if the EDID lists only one specific resolution, interpreting this and sending out the right signal is still totally up to the video source and it is possible for the video source to ignore the EDID. One important note, I did say “try” to force a video source. Uploading a custom EDID (with just one resolution) to the capture device can resolve the issue. Nothing you do from the OS can change the laptop’s mind. For example, we’ve found that on some laptops even though you tell the laptop to output video at 1080p, when it sees an EDID that has other resolutions, it picks one it likes better. To do this you could upload an EDID that only lists that single video resolution. Sometimes you want to try to force a video source to use a specific resolution. Here are a few reasons you may want to upload a specific EDID rather than using the default. Sometimes, though, it’s useful to upload a specific EDID to the device, telling your video source to provide the output you want to capture, or adding a custom resolution or timing that isn’t in the default EDID. This default EDID is generally good and works with a broad range of video sources. Our products come pre-loaded with a default EDID that lists a large number of supported resolutions, colour spaces, timing information etc. camera, laptop, scientific instrument, etc) to any Epiphan capture (or capture and streaming) device, our device acts as the “monitor” for your video source. However I do want to address the practical concerns of EDIDs when using our products. I’m not going to get too low level or technical here, as this information is already available online and is just a quick Google search away. Today’s HDMI devices most often use E-EDID and include information to also specify audio capabilities including codecs, sampling rates, and channels. In 2000, E-EDID expanded this, allowing multiple 128 byte chunks. It had vendor and product information, EDID revision, display capabilities (size, resolution, sync, etc), colour space, and detailed resolution/timing information. When EDID was first introduced in 1994 it was short and sweet at just 128 bytes. Plus, often when we speak of EDID we are actually referring to E-EDID, or Enhanced Extended Display Identification Data.

It includes vendor and product id, serial number, manufacture date, size of the display, resolution and frequencies supported, and detailed signal timings for native resolutions. Of course if you really get into it, EDID, which stands for Extended Display Identification Data, is far more complicated. EDIDs are important for DVI and HDMI video sources and occasionally used for VGA sources. This allows the video source to then send out a video signal that is supported by the monitor. My usual basic description is that EDID is the information provided by a monitor to the video source describing the monitor’s capabilities. This question comes up a lot when troubleshooting unusual video capture issues with customers.
