Recording UEFI BIOS on Thinkpad T14s

2021-05-03, 19:50 PM

I have a Thinkpad T14s AMD one. I am trying to record its UEFI BIOS and everything while it,s booting. I know that it can be done using an HDMI capture device. I have one too, but when I can't configure it to output to the main LCD and clone to HDMI simultaneously.

 

There is an option in BIOS to chose a display, but it only lets you chose 1. It also says that it will clone to every type c display, but I don't have a type c recorder and it still doesn't say that it will clone to the main display. Also, I have seen people do it with an HDMI recorder and the same model of Thinkpad on youtube.

 

I know that I can connect 2 displays, but it is still uncomfortable, I want specifically to use a built-in LCD.

Hello dani0854!


Welcome to community forums

 


There should be an option in the BIOS to change Boot to display so BIOS can be projected externally. Without this option, the display for BIOS will just be internal.

I know about this option, but when I chose to project externally, it stops projecting internally. But I have seen people project internally and externally at the same time on that model of Thinkpad (youtu.be/pZO_t4n-_kE).

There are several model variants of T14s. You can try loading the BIOS default setup.

 

If the issue is the same, kindly send us the MTM of your machine and the BIOS version as well so we could check.
