What’s EDID?
EDID records the information of a display such as the dimensions/screen size, original resolution, color properties, frequency range limits, etc. EDID handshakes enable the information exchange and when the computer gets it, it will deliver the image that fits the display.

What’s an EDID Emulator?
EDID emulator helps address communication issues between an HDMI video source and a display. By copying or ghosting an EDID, the emulator can relay information from the display to the computer.
If you are using third-party equipment like HDMI extenders, switches, or KVMs in your A/V setup, or have an HDMI repeating device (AVR) connected in the middle of the source and display, EDID communication could get complex.
You may get a black screen or error alarms and do rounds of troubleshooting with no results. You probably encounter EDID malfunction. And it is difficult to really locate the problem and fix it directly.
Using an EDID emulator is a potential way out and sometimes people give it a shot and find the setup works again.
Benefits of Using an EDID Emulator
An EDID emulator is an adapter that is plugged into a computer’s output jack or a display’s input port, and it makes the computer think that it is connected to a display that supports certain resolutions, refresh rates, and other audio/visual features (according to what EDID your emulator is offering).
If you are facing these troubles, you may like to give it a try — use an EDID emulator.
1. The monitor can’t output images with certain resolutions/refresh rates.
In the world of A/V, there are numerous standards, protocols, and different AV features that work based on them. And they keep evolving into a new generation for better performance and higher efficiency.
When your devices are of different standards/generations, they may not be able to communicate as we expect. Even though your monitor supports 4K 120hz, if the handshake with your PS5 game console fails, you won’t get the right image. An EDID emulator may help streamline communication and fix the problem.
2. KVM switch that messes up your desktop.
You may use a KVM switch to connect multiple systems to one or more of your monitors. And one thing could happen. When you switch back to your PC, the icons on the desktop are messed up.
This is because when you are working on another device, the KVM switch cut the connection to your PC. When you switch back, the EDID exchange will be initiated again and the icons are replaced as the data is refreshed.
The solution is to change to a KVM switch that has built with the EDID emulation or add an EDID emulator to your setup.
3. Other benefits of using an EDID emulator.
3.1 Remote Management: An EDID emulator can be used to remotely manage display settings. This can be particularly useful in digital signage applications, where multiple displays may be located in different areas.
3.2 Testing: An EDID emulator can be used for testing and troubleshooting purposes. It can be used to test the compatibility between different devices or to verify that a device is correctly identifying the capabilities of a display.
3.3 Reduced Downtime: In case of display device failure or replacement, an EDID emulator can help to ensure that the new device or replacement device will work with the existing setup, minimizing downtime.
Conclusions
Overall, an EDID emulator can help to improve the performance and compatibility of display devices, reduce downtime, and simplify display management. If you need to add intermediary devices to your setup, one with EDID features could save you a lot of trouble.
