Finding your monitor’s Extended Display Identification Data (EDID)—which includes details like the manufacturer, native resolution, and supported timings—can be done through built-in Windows tools, GPU control panels, or specialized software.
Here are the best methods to check your monitor’s EDID/PNP ID: Method 1: Using Windows Device Manager (Best for PNP ID)
This method shows the basic Plug and Play (PNP) ID, which is a key part of the EDID. Press Windows Key + X and select Device Manager. Expand the Monitors section. Right-click on your specific monitor and choose Properties. Navigate to the Details tab. From the Property dropdown menu, select Hardware Ids. Method 2: Using NVIDIA Control Panel
If you have an NVIDIA GPU, the control panel can show you if the EDID is being read correctly. Open the NVIDIA Control Panel.
Under the Workstation tab in the left pane, click View system topology.
Locate your display and click the [+] icon to expand the branch. Check the EDID Source:
Monitor: The system is successfully reading the actual monitor EDID. File: A custom EDID file is being used. None: No EDID data is being detected. Method 3: Using Third-Party Software (Most Detailed)
For a full, raw dump of the 128-byte (or more) EDID structure, you can use specialized tools.
Monitor Asset Manager (MonInfo): Download and run this tool. It will display the raw EDID, including color characteristics, manufacturer data, and supported video modes. Troubleshooting
Default Monitor Error: If the device manager shows “default monitor,” it often means the EDID is not being read properly. This is common if you are using a VGA connection or a passive adapter.
Ensure Proper Connection: To properly read EDID data, connect your monitor using HDMI or DisplayPort.
