* If everything is working, you can make this config permanent: `kvmd-edidconf --import=/root/edid.hex`. This command will write the EDID to `/etc/kvmd/tc358743-edid.hex` in a pretty format.
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).
PiKVM can mimic physical monitors. You can find the appropriate EDID in [this database](https://github.com/linuxhw/EDID) and import its HEX code to PiKVM. Choose something with a maximum resolution of 1920x1080 or 1920x1200.
??? example "1920x1080 as preferred. Useful for Gigabyte GA-H77-DS3H, Intel NUC or [ASRock H670 PG Riptide](https://github.com/pikvm/pikvm/issues/715)"
??? example "1280x1024 as preferred, disabled 1080p at all. This may be necessary in extremely rare cases if the BIOS is completely buggy. In the future, we will provide a way to dynamically switch EDID"
To edit the EDID, it is best to use third-party utilities, such as the recommended advanced
[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:
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
```
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:
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`:
```
# kvmd-edidconf --import=/root/myedid.bin --apply
```
7. Switch filesystem to RO-mode: `ro`.
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:
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:
