-## EDID examples for V4+
+## Force 1080p by defailt on PiKVM V0+
 
-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.
+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.

+## My monitor does not support the 1920x1200 mode
+
+PiKVM V4 supports the advanced capture mode of 1920x1200.
+If your physical monitor is limited to 1920x1080, then part of the image from the bottom will be cropped.
+
+To avoid this, you can change the resolution of the host OS, or if the OS does not support this,
+disable the 1920x1200 mode on PiKVM itself:
+
+```console
+# rw
+# kvmd-edidconf --import-preset=v4plus.no-1920x1200  # Or v4mini.no-1920x1200
+# reboot
