How to force Intel HD graphics (HD 4000 and so on) to output 1440p

	I have a 1440p monitor with an old computer that has Intel HD 4000, which doesn't support outputtin to 1440p natively. I bought a high-end AMD graphics card and a high-end NVIDIA card, but they both don't work well one way or another. The damn AMD driver doesn't support audio, the NVIDIA... don't ask.

	Anyway, I figured there is a way to do 1440p natively on Intel, you just have to have 55Hz. You'd have to have a Windows setup.

	Follow this instruction, you should be able to get 2560x1440@55Hz on Windows

	If that works, export your edid using Moninfo:

Chroot to pi sd card

	#!/bin/bash

	# This script allows you to chroot ("work on")
	# the raspbian sd card as if it's the raspberry pi
	# on your Ubuntu desktop/laptop
	# just much faster and more convenient

Chroot into Raspberry Pi ARMv7 Image with Qemu

    # raspbian stretch lite on ubuntu

### You can write the raspbian image onto the sd card,
# boot the pi so it expands the fs, then plug back to your laptop/desktop
# and chroot to it with my script 
# https://gist.github.com/htruong/7df502fb60268eeee5bca21ef3e436eb
# sudo ./chroot-to-pi.sh /dev/sdb
# I found it to be much less of a pain in the ass and more reliable
# than doing the kpartx thing
