Hello,

I got this laptop:

https://www.dell.com/en-us/shop/workstations-isv-certified/precision-5570-workstation/spd/precision-15-5570-laptop

Is there a BIOS setting or a way to output the main laptop screen pre-boot through HDMI to TV?

So when I plug the laptop HDMI to my TV, I can see that the laptop shows on TV and that is fine, but when I restart the laptop, the pre-boot BIOS/loading screen are not showing on my TV – Currently it shows a black screen and my tv says “Connecting…” or “Loading…”. It only starts showing when it reaches the Windows login screen.

Is there a BIOS setting or a way/workaround to make it show the initial load screen or BIOS screen in my TV?

Update: I was told by Dell that if the lid of the laptop is closed, it will output to the HDMI instead. That’s the the design in the firmware. There is no BIOS setting to change it.

Is there a way to keep the lid open and somehow still invoke this “hidden” functionality?

Thank you.
