I had removed the screen of my chromebook, however the uefi menu does not show up on external monitor, how can I fix this?
Boot device
EDK2 UEFI menu only shows on laptop screen
Show also on HDMI display
you need to provide the actual firmware verison as reported by the device itself (on the firmware setup screen). Don’t know where you got what you listed above.
Also, it would be helpful to know the screen type and resolution of the external display. The internal panel on KIP is 1366x768, so if your external display doesn’t support that, there’s no way that the internal display can be mirrored at boot.
Ah apologies, Firmware ver: 05/01/2019
As for the screen res I will take that into note, thanks.
2019? you might want to update to the latest version, given you’re 7 years out of date
Yeah.., but sadly the chromebook itself (KIP) has been EOL for a long time, hence why i went for UEFI
what you’re saying is irrelevant. EOL or not, you’re running 7 year old firmware, if that is actually the firmware date. I’m not going to waste any time trying to diagnose any issue there.
If you want further support, update to the latest firmware (which is 3 days old) and report back.
May I know if you’re referring to the script’s FW version or the device’s? As the script’s one is 2026-10-28 . If its the device’s, how may I update it?
I’m not sure how this is so hard.
when you run the script, it will give you the date the script was updated, but it will also show the current version of the firmware and date, as reported by dmidecode.
The first menu option of the script is literally to update the firmware.
ok, so if you just now/recently installed the UEFI Full ROM firmware, the script should show that your device is running the latest version. The date of the stock firmware before you flashed isn’t relevant.
The current firmware shows you the date and version on the setup menu screen when you press ESC for the boot options/settings.
Given that you’re running the latest Full ROM firmware, the issue is simply that your external display is not capable of mirroring the laptop panel at it’s native resolution, which is the only mode supported at boot.
Ah yeah thanks, the monitor one did work. Smaller (standard) monitor worked, the bigger one was having the issue. Thanks!
