Re:P14s gen 2: BIOS update 1.36 breaks 4k display function

2021-06-25, 7:19 AM

Hello,

 

Thanks for brining this to our attention, engineers have been made aware of this discussion and are investigating the issue. It would help them if anyone experiencing or has experienced the described symptoms could post their full MTM, (Machine Type Model), number which will look similar to 20VX0000US.

 

Thanks

 

Andy

My device is 20VX000KGE. P14s Gen 2i Color profiles cannot be found and downloaded with x-rite after updating to 1.36.

Re:P14s gen 2: BIOS update 1.36 breaks 4k display function

Product number 20VXS02800.

 

After the upgrade from 1.34 to 1.36, Windows was only able to recognize the display as a "generic pnp display".

 

X-Rite gave an error message regarding not being able to find (and download) the profiles for this display, then it quit.

 

Color management was not active. Colors inaccurate. Manually selecting a profile also didn't fix the colors.

 

The "HDR" function / toggle, normally available via the Windows display settings, disappeared.

 

After downgrading to 1.34 everything reverted and the display worked normally again.

 

 

I see a new BIOS 1.37 was released today. But the notes don't mention this issue, and since you're only asking today, I assume it will not be safe yet, right?

I had the same issue after updating from BIOS 1.34 to 1.36.  However, I'm happy to report that BIOS update 1.37 restored x-rite color assistant display profiles after running the x-rite program, getting the message that display profiles are missing, and then clicking the link to have them restored from the Lenovo server. Thanks Lenovo for the quick fix!

Thanks for testing 1.37, James! I was reluctant to try it, since when 1.37 was released Lenovo hadn't even registered the issues with 1.36. But now I can also confirm that 1.37 is fine, the display is being recognized correctly.

 

(1.36 had some new BIOS controls that also disappeared in 1.37. I'm wondering if 1.36 was mistakenly released for this device and wasn't intended for it in the first place.)
