I have Linux Mint 17 on my laptop. Also I have 22'' monitor connected to laptop using HDMI cable. My disk if fully encrypted with LUKS and LVM. On boot I get graphical prompt to enter password for encrypted partitions. Screen resolution on on both laptop and external monitor is wrong when asking for password. Graphical prompt and linux mint logo is moved to top left corner on both monitors and rest of space is black. Resolution is correct only after I log in to my profile. This is what xrandr shows when I'm logged in:

After mounting encrypted disk I can change resolution on monitors using xrandr command. But this command is unavailable with initramfs.
I was recently fixing another laptop screen brightness on boot using initramfs script and it worked. This script was setting brightness by echoing correct value to to /sys/class/backlight/acpi_video0/brightness. Can I also use something similar to change screen resolution somehow?
UPDATE
I've tried @mikeserv solution:
EDID files from monitors (not sure if they are correct):

drm_kms_helper.edid_firmware=HDMI1:/lib/firmware/edid/1920x1080.binIt didn't change anything. So I also tried:
drm_kms_helper.edid_firmware=HDMI-1:/lib/firmware/edid/1920x1080.bin drm_kms_helper.edid_firmware=HDMI1:edid/1920x1080.bin drm_kms_helper.edid_firmware=HDMI-1:edid/1920x1080.bin
No luck at all. Everything is like it was before I took steps from above.
I also want to add that when HDMI monitor id disconnected resolution on laptop monitor is correct.
What am I doing wrong?
UPDATE 2
Still not working. Steps I took:
Found out correct names for my monitors:

Also I've tried setting it just for one monitor. But no luck at all. I'm starting to think that it is not a problem with resolution but with plymouth image itself. When I see boot image it is not blurred, stretched or anything and Linux mint logo is sharp and clear. It's just smaller than my screen and placed in left top part of my laptop and HDMI screen.
I've found this bug that is really similar to my problem. So I think I must wait for them to fix this.
