2 Installing EDID Designer EDID Designer features one-click installation for a fast and trouble-free setup. To install EDID Designer: 1. Navigate to the Kramer’s EDID Designer Web site and click the install link: www.kramerelectronics.com/downloads/setups/ediddesigner/setup.exe The file downloads to the lower left corner of your browser: 2. Click setup.exe. A security warning opens: 3. Click Run.
4. Click Install. Note: At this stage, a message appears if DotNet 4.5 is not installed on your computer. Follow the instructions to install DotNet 4.5. After installation you may be required to reset the computer. Perform the reset and do not take any further action. EDID Designer continues to install automatically. The installation progress window appears: 5.
The latest version of the device adapters downloads from the Web. Allow it to run to completion the first time otherwise device adapters or their latest versions might not be available for use. To launch EDID Designer: Click Start and click on the application. The EDID Designer main screen opens (see Figure 1) and automatically updates device adapters.
3 Defining the EDID Designer Figure 1 defines the basic elements of the EDID Designer main screen.
# Feature 9 MONITOR Panel Displays the EDID of any monitor connected to the PC running the application Function 10 Browse Button Click to browse the disk for EDID files 11 LOCAL EDID FILE Panel Displays all saved EDID files from a disk location Figure 2 shows EDID Designer with a connected device, monitors, files, and an EDID open for editing with the following additional elements: Figure 2: Full Screen EDID Designer - Defining the EDID Designer 7
# Feature 12 Select All Checkbox Check to select all inputs Function 13 Connection Status Icon Shows if the input or output is connected or disconnected 8 14 ADD Button Click to add and specify a CEA Extension 15 Binary EDID Map Displays the binary representation of the EDID being viewed or edited.
Figure 3 shows the sources of the EDIDs that are used by EDID Designer and whether they are read-only (R/O) or read/write (R/W). Note: To edit an EDID from a R/O source (for example, a local PC monitor), save it locally on your PC. This changes it to a locally saved file that can be edited.
4 Using the EDID Designer EDID Designer is designed using drag-and-drop technology to make EDID file manipulation very easy and intuitive. Any active EDID cube is dragged to the desktop panel for viewing or editing and when saved, it is saved to the source from which it was taken. Legal drags are symbolized by a green cross + in the dragged cube and when dropped, the action is completed. Illegal drags are symbolized by a red no-entry symbol Ø in the cube and when dropped, the action is discarded. 4.
4.2 Connecting to a Device Connect to a Kramer device (for example, a matrix switcher) to view, edit and copy its EDIDs. The list of supported Kramer devices updates each time you launch the software and your PC is connected to the Internet. Note: When a new version of EDID Designer is available for installation, a new version notification appears upon launch. Important: When your Kramer device supports both Protocol 2000 and Protocol 3000 communication protocols, make sure it is set to Protocol 3000 mode.
After successfully connecting to the device the Connect button becomes Disconnect and next to it, the device type is displayed. All inputs, outputs and default EDIDs are displayed in the appropriate panel. 4.3 Writing an EDID to an Input Changing the EDID block on your Kramer device input channels is a powerful way to take control of the signal your sources output. You can do that by writing an EDID block EDID from a file, a default EDID, a local monitor or from an output to an input.
Note: Some devices, by default, manipulate the written EDID to better suit their device properties. If desired, click the checkbox to prevent the device from modifying the data. In devices not supporting this prevention, the checkbox is grayed out. Note that modification of the written EDID might occur. 2. Click Yes to write the EDID to the input or No to discard and exit the action. 4.4 Opening an EDID Monitor, output and default EDIDs are read-only.
3. Click Save to write the EDID to its source or Discard to throw out any changes made since the last save. 4.6 Copying or Deleting an EDID to/from the Disk You can make additional copies of an EDID file on the disk or delete the file from the disk. To make an additional copy of an EDID on the disk: 1. In the Local EDID file panel, right-click the desired EDID cube. The Delete/Copy window opens. 2. Click Create a Copy.
To delete an EDID from the disk: 1. In the Local EDID file panel, right-click the desired EDID cube. The Delete/Copy window opens. 2. Click Delete. A warning message appears: 3. Click Yes to delete or No to exit.
5 Editing an EDID EDID Designer allows the user to manipulate the full EDID, with all its parameters and extensions using the Advanced tab (see Section 5.3). The Advanced tab is a full representation of the EDID according the White Paper referenced in Section 1, and uses the exact field names used in the EDID white paper. The Simplified tab (see Section 5.1) provides a summary view of the EDID showing the most frequently changed parameters based on the most commonly used functions.
5.1 Using the Simplified Tab The Simplified mode is used for easy editing of the frequently used EDID properties. Since the EDID block structure includes many cross references between data fields, the Simplified mode prevents the user from creating EDID blocks that might cause signal compatibility issues and the application does NOT alter the EDID data block structure. This means that in the Simplified mode the application denies any editing actions that might change the total size or order of the block.
5.2 Simplified - General Information General information of the EDID block has no real functional meaning. We suggest using the SN as a cross-platform file identifier.
5.2.1 Simplified – Video - Established Timings Video-Established-Timings are collected from established timing 1 & 2, the most common and standard resolutions. The source outputs the highest possible resolution checked from this list, only if there are not compatible resolutions under the standard and detailed timing. The same or similar established timings lists may be located in several sections of the EDID block.
5.2.2 Simplified – Video - Standard Timings Video-Standard-Timings gathers any standard timings (regular and from all descriptors) set to display as ‘Standard-Timing’. The source outputs the highest possible resolution defined in this list, only if there no compatible resolutions under the detailed timing resolutions. The user can locally save a standard timing from the EDID block or import to it a standard resolution from the working directory.
5.2.3 Simplified – Video - Detailed Timings Video-Detailed-Timing gathers details from all descriptors set to display as “detailed-timing”. The source outputs the highest possible resolution defined on this list. Import/Export – from/to attached Detailed Timings list. “In-use” list items are marked as checked.
5.2.4 Simplified – HDMI Audio HDMI Audio screen is shown if a CEA extension block exists and one of its descriptors is AUDIO. If any of a particularly defined audio configuration (see advanced-ext’-audio) exists, check the block If none exists, uncheck the block If not checked, this sets all the matching “short-audio-blocks” to a “placeholder” setting – pcm/192kHz/24-bit. This is considered a vacant block.
5.2.5 Simplified – HDMI-Spec-Features HDMI-Spec-Features screen are shown if a CEA extension block exists and one of its descriptors is a Vendor-Specific CEA block.
5.3 Using the Advanced Tab The following sections describe several workflow aid features found in the advanced mode. 5.3.1 Advanced - Established Timings Advanced mode does not aggregate the established timing lists as in simple mode, so to remove compatibility from a certain resolution you must uncheck it manually from all lists (in case the standard timing list also exists in the descriptors).
5.3.2 Advanced – Editing Descriptors Some descriptors can be set to one of several types. We suggest in most cases that the user not change the descriptor type. If you do change a descriptor type, it is important to note that the content of the descriptor does not change, only the way the source treats this data block changes. Therefore, when changing a descriptor type, make sure to check that the data after the change still has a meaningful interpretation under the new descriptor.

5.4 Using CEA Extensions CEA extensions are used for specifying additional parameters or information on other interfaces. 5.4.1 Adding a CEA Extension in the Advanced Mode To add a CEA extension: 1. Click the ADD button at the bottom left of the desktop panel. 2. Select CEA Ext. An Extension Info tab opens and 128 bytes are added to the byte map. To specify the CEA extension block type: 1. After opening a CEA extension, click the ADD button. 2. Select CEA Ext Block. The Ext Block drop down box opens: 3.
5.4.2 Extension – Audio To configure the Audio Format code: Click the dropdown box and select the desired code. The bitrate information automatically matches the selected code. To configure the number of channels: Click the dropdown box and select the number of channels. To add another audio descriptor: 1. Click the AddShortAudioDescriptor button. Another configurable audio descriptor opens. (Only one additional descriptor is allowed.) 2. Configure it as described in the previous two steps.
5.4.3 Extension – Video This allows you to specify all custom or non-standard resolutions and indicate whether the resolution is native. To specify the video identification code: Click the video identification code dropdown box and select the desired resolution. (To remove, click the Remove button.) Native resolution defines ONE additional native video resolution in addition to the one specified in the Detailed timing of the first block.
5.4.4 Extension – Vendor Specific This allows you to specify the vendor specific CEC address. 5.4.5 Click the up and down arrows to increment or decrement the value shown. Extension – Speaker Allocation This allows you to specify the speaker configuration according to front, rear, left, right, center, woofer and high.
5.4.6 Extension – Additional Descriptors These descriptors allow you to include additional video specifications.
