The examples below are tested on these devices, but they are also suitable for others. To edit or create EDID you can use [AW EDID Editor](https://www.analogway.com/emea/products/software-tools/aw-edid-editor).
## Default EDID
If for some reason you need to go back to the default EDID (changing attached device etc), you can find it locally on the Pi at `/usr/share/kvmd/configs.default/kvmd/edid` or in the [kvmd repo](https://github.com/pikvm/kvmd/blob/master/configs/kvmd/edid).
## Editing EDID ## EDID examples for V4+
To edit EDID, it is best to use third-party utilities, such as the recommended advanced PiKVM can mimic other physical monitors. You can find EDID in [this database](https://github.com/linuxhw/EDID), then import the HEX code. Choose something with a maximum resolution of 1920x1080 or 1920x1200.
[AW EDID Editor](https://www.analogway.com/emea/products/software-tools/aw-edid-editor) for Windows (it's working great in wine)
or [wxEDID](https://sourceforge.net/projects/wxedid). Both editors work with the binary EDID format, but you can easily import and export it
to PiKVM using the `kvmd-edidconf` utility.
So, to tune EDID on PiKVM, use the following steps: ??? example "ASUS PA248QV, 1920x1200, with sound"
Taken [here](https://github.com/linuxhw/EDID/blob/master/Digital/ASUS/AUS2487/2B473481CAE6), as described above.
1. Switch filesystem to RW-mode: `rw`.
2. Export the system edid to the binary file `myedid.bin`:
``` ```
# kvmd-edidconf --export-bin=/root/myedid.bin 00FFFFFFFFFFFF0006B3872401010101

``` ```
3. Copy this file to your PC with the editor. Use SCP, Putty or something like that. Open this binary file in the editor and change the necessary parameters. Edit, save and copy it back to PiKVM.
4. Convert the binary file to the HEX and test it: ??? example "DELL D2721H to avoid black screen on some HDMI splitters, 1920x1080, no sound"
Taken [here](https://github.com/linuxhw/EDID/blob/master/Digital/Dell/DEL2013/EEE824E681BF), as described above.

5. If everything works fine, install the new EDID file into the system:
```
# cp /root/myedid.hex /etc/kvmd/tc358743-edid.hex
```
6. Alternative to step (4) and (5): if you are confident in your abilities, you can immediately install the new `myedit.bin` into the system and apply it instantly, without the need to use the temporary `myedid.hex`: ## EDID examples for V2+
```
# kvmd-edidconf --import=/root/myedid.bin --apply
```
7. Switch filesystem to RO-mode: `ro`. Copy the contents into a file, for example `/root/edid.hex`, then follow the same steps as above.
The `kvmd-edidconfig` utility has the ability to change some simple parameters without using an external editor. For example you can change the vendor, model name and enable [HDMI audio](audio.md) on the PiKVM virtual display:
```
# kvmd-edidconf --set-mfc-id=LNX --set-monitor-name=PiKVM --set-audio=1
# reboot
```
!!! note
Windows cache's drivers and registry settings so changing the monitor name is not enough, you will also need to change the product ID and/or the serial number along with the monitor name:
`# kvmd-edidconf --set-monitor-name=TOSHIBA --set-mfc-id=TTP --set-product-id=34953 --set-serial=2290649089 --apply`
## Custom EDIDs
Copy the contents into a file, ex: myedid.hex then follow the same steps as above starting at step 5.

## 1920x1200 video mode
Both PiKVM V4 Mini and Plus devices support a resolution 1920x1200, however, for compatibility reasons, the default configuration uses 1920x1080. To enable 1920x1200, follow [this manual](edid.md).
