[Help] Screen Issues Dell Inspiron 7548 HD5500 4K

I don’t seem able to change it. I extracted this from bios asi per guide:
View attachment 360909

And then change it here:

But if I enter again to the grub menu to check if it’s changed this appears:

The BIOS is playing me.

Maybe try setup_var2.

Maybe try setup_var2.

Already tried, same thing happens.
Don't know what else to try nothing seems to fix it.

Well I booted without the Framebuffer patch, scaled the display and it worked. I have full QE/CI. Nos it’s scaled to look like 1680x945, the 1920x1080 it’s that causes problem, what could it be? Can it be fixed?
Note:
I downgraded BIOS and set DVMT to 128MB successfully but it did not change anything I was still having the same problem.

What do you mean by "the 1920x1080 it's that causes problem"?
Please take the time to write coherent questions with details.

Yeah sorry about that. Now I have scaled like this, and it works well but everything it’s too big (there says Looks like 1680x945)


The option that causes problems with the screen is the one on the right. There says Looks like 1920x1080


With this option the screen looks completely grayed out or like this:


Can I fix that? I would like to use the last option (which is also the default for display) because the folders and icons on the screen are way too big with the scaled version.
Thanks @RehabMan

Try different ig-platform-id values.

Other than that, you might want to experiment with different memory configurations for the framebuffer (eg. patching via WhateverGreen framebuffer-stolenmem and framebuffer-fbmem).
