Capture · Record · Stream · Encode · DecodeCapture · Record · Stream · Encode · DecodeEDID is the block of data a display sends to its source to say which resolutions and refresh rates it accepts. A capture card looks like a display to the source, so it presents an EDID too, and the source chooses its output from that list. On Pro Capture cards with HDMI or DVI inputs you can replace the EDID from the HDMI tab of the driver panel, which lets you hold a source to the format you want. If the EDID does not match what you intend to capture, you get the wrong signal. A 4K60 source will send 1080p30 if the EDID offers only 1080p30.
Each card ships with a default EDID that describes the formats that model accepts. Most sources work with it as it stands, so try the default first. You can return to it at any time with the Reset button in the driver panel.
A custom EDID is useful in three situations: a source is sending a lower resolution than you want; you need one specific resolution or frame rate, for example 1080p50 to match the rest of a system; or a source keeps changing mode, and offering it a single mode keeps it steady. SDI inputs do not use EDID, so this applies to HDMI and DVI inputs only.
The EDID controls are in the capture card's driver panel, on the HDMI tab. Under EDID, Save writes the card's current EDID to a file, Load imports an EDID file into the card, and Reset restores the default. The panel does not edit the contents itself. You change the saved file in a separate EDID editor and then load it back. For USB Capture devices, the EDID is managed in the USB Capture Utility V3, on its HDMI tab.
Because the EDID is saved and loaded as a file, you can reuse one file across many cards. Save it from a card that is set up correctly, then load it into the others. That gives every room or workstation the same behaviour in a site-wide rollout. Keep a copy of the original file so you can compare later.

Open the capture card's driver panel and go to the HDMI tab. Under EDID, click Save to keep a copy of the current EDID as a file. Edit that file in an EDID editor so that it offers the formats you want, then click Load to import it into the card. Reconnect the source so that it reads the new EDID. Reset returns the card to its default.
The source reads the EDID from the Pro Capture card and picks a resolution from the formats offered. If it picks one you do not want, load a custom EDID that offers only the resolution you need. The source then has one choice. Check first that the source itself is not set to a fixed output resolution in its own menu.
You can load a custom EDID into the card from the HDMI tab of the driver panel, and it replaces the default until you click Reset. After loading it, restart the PC and reconnect the source once to confirm the source still sends the format you expect before you rely on it.
Use an EDID that offers the resolution and frame rate you want the source to send. For 1080p60 capture, the EDID should offer 1080p60 as its preferred mode. For 4K at 30 fps, it should offer 3840x2160 at 30. An EDID limited to one mode leaves the source one choice. Stay within what your card accepts. The EDID is saved and loaded on the HDMI tab of the driver panel.
Yes. The Load button under EDID on the HDMI tab of the driver panel imports an EDID file into the card. That gives you precise control over the formats the card offers, which helps with unusual sources that do not behave well with the default EDID. Save the original first so you can go back.
The source is reading the EDID and choosing 1080i from the modes offered, or it is set to 1080i in its own menu. Check the source's output setting first. If it follows the EDID, load an EDID that offers only progressive modes, such as 1080p60, and the source will send progressive video.
It depends on the model. The Pro Capture HDMI 4K Plus, for example, accepts 8, 10 and 12-bit HDMI signals in RGB 4:4:4, YCbCr 4:4:4 and YCbCr 4:2:2. An HDMI source only sends more than 8 bits if the EDID says the input accepts it. Your capture software must also request a 10-bit format, so check the specification of your model and your software.
