I have this laptop 4k Toshiba p50t b 112. The features are as follows:

Processor: Haswell 4th generation IntelCore i7-4710HQ IntelTurbo Boost Technology 2.0 clock speed : 2.50 / 3.50 Turbo GHz 3rd level cache : 6 MB Ram: 16,384 (8,192 + 8,192) MB
Hard disc: Crucial SSD 512gb/interface : Serial ATA
Blu-ray Disc
Graphic: (15.6”)/ internal resolution : 3,840 x 2,160
AMD Radeon R9 M265X : 2GB dedicated VRAM /GDDR5 Video RAM and intel HD 4600

I tried with your guide, installing FakePCIID and Fakepciid_intel_Hd_graphics, devices FakeID 0x0x4128086 and Ig-platform 0x0a260006 but not works, still continue with 31 mb.

I attached my efi zip, ioreg and ssdt.

Thanks for your early reply.

Regards.

The ACPI is not patched properly. The Clover is not as per guide. 4K/UHD/QHD has additional requirements. DVMT Pre-alloc must be set to 64 MB or more or need to unlock the BIOS and increase the DVMT. The other way is to patch via Clover. Read here: https://www.elitemacx86.com/threads/faq-read-first-questions-related-to-laptop.175/
AMD is not supported as it's a switchable configuration. You must disable it. Read here: https://www.elitemacx86.com/threads/guide-how-to-disable-discrete-graphics-in-dual-gpu-laptops-nvidia-amd.180/
