* 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.
PiKVM V3 (or DIY V0-V2) has a hardware limit of 50Hz for 1080p mode, and this is a less common frequency than 60Hz.
Therefore, on V3, the default mode is 720p. Some OS (like Proxmox) may not work well with 720p,
so you can force 1080p resolution by default:
```console
# rw
# kvmd-edidconf --import-preset=v3.1080p-by-default # Or, for example, v1.1080p-by-default
# reboot
```
## Disable 1920x1200 on PiKVM V4
PiKVM V4 supports the advanced capture mode of 1920x1200. If it bothers you
(for example, if you use a physical monitor 1920x1080 with [video passthrough](pass.md)),
you can easily disable it and use only 1920x1080:
```console
# rw
# kvmd-edidconf --import-preset=v4plus.no-1920x1200 # Or v4mini.no-1920x1200
# reboot
```
## Other EDID examples for PiKVM V4
PiKVM V4 can mimic many 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 motherboards such as [ASRock H670 PG Riptide](https://github.com/pikvm/pikvm/issues/715), Gigabyte GA-H77-DS3H, MSI series such as B550M, B660M, Z690-A and X570. Also the Intel NUC."
??? 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:
