Bad refresh screen in laptop HP ENVY Notebook - 17-k251na

Recommended Posts

Hello, I have installed Olarilla Monterey without problems on my HP ENVY Notebook - 17-k251na and both wifi and bluetooth work, however the screen at startup looks like it lacks screen refresh (the graphics card is an Intel HD5500) and the audio (Alc290) I can't get it to work even changing the alcid=x Let's see if someone can help me at least on the subject of my screen, I attach a video when starting the laptop, Note: I was able to install Monterey by changing the legacy mode in the bios and not efi.

Thank you.


I´m using translator, i am Spanish=Español.

Sure, but isn't there another way that without activating CSM the screen doesn't show like this? In CSM mode the screen looks darker. By the way, who would I have to pay, for example, 10 €uros to fix my sound? I'm tired of looking for how to activate the sound on my laptop (ALC290) but I don't know how to do it. Thank you anyway.
