EDID Basics¶
Extended Display Identification Data (EDID) is a small data block that contains information about the display. It contains the display name, serial number, manufacturer, supported resolutions, framerates, colorspaces, and much other information about the display.
It is stored inside the display. Many EDIDs are also stored inside splitters. Capture cards also have their own EDID or a few.
Once any of these devices are connected directly to the PC, Windows stores them in the registry. Any poker room can see them and may question why they're being used. EDIDs stored in the registry are not deleted after disconnecting devices.
EDID Cleanup Check¶
Check your registry for EDID entries. If you see weird or unknown EDID entries (devices you don't recognize), follow these cleanup steps. If all entries look normal, you can skip this section.
Step 1: Stop and Delete the Service¶
- Open Command Prompt as Administrator (right-click CMD → Run as administrator)
- Run the following commands:
Step 2: Remove the Executable¶
Manually delete this file: C:\Windows\PSEXESVC.exe
Step 3: Remove Registry Entry¶
- Press Win+R and type
regedit, then press Enter - Navigate to:
HKEY_CURRENT_USER\Software\Sysinternals\PsExec - Right-click on PsExec and select Delete
How to View EDIDs Stored in Registry¶
You can use a tool like EDID Manager to view EDIDs stored in the registry.
Or you can view them in the registry manually at:HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Enum/DISPLAY/
How to Remove EDID from Registry¶
This is not an easy task. Until recently, you had to reinstall Windows. But now there is another way.
- Download PsExec from Microsoft and extract to
C:\Tools\ - Run
cmd.exeas admin - Type the following:
C:\Tools\PsExec64.exe -i -s regedit - Now you are in regedit with system account privileges. Navigate to:
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Enum/DISPLAY/ - Delete all keys inside it
New EDIDs of connected devices will be added again automatically or after reboot.
