Hi,

In order to change the screen resolution to a Kali Linux using Hyper-V follow these steps:

Add these lines to this file:
sudo vim /etc/initramfs-tools/modules

hv_vmbus
hv_storvsc
hv_blkvsc
hv_netvsc

In the terminal type:
sudo update-initramfs -u

Reboot.

sudo nano /etc/default grub GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=hyperv_fb:1920x1080"
sudo update-grub

Regards,
Rubén
