How to force Intel HD graphics (HD 4000 and so on) to output 1440p
View intel-hd-4000-1440p-notes.txt
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:

### 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

# 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
