Hi! I can also confirm the issue with a TV that does not provide any EDID data. The "drm_kms_firmware.edid_firmware" option worked with the 4.13 Kernel. With the 4.15.x Kernel it stopped working. In fact it seems to disable the display completely at boot so that I have to remove it as a boot option to be able to use the system at all. Kernel 4.16.0-1 still has the issue. Neither drm_kms_firmware.edid_firmware=edid/1920x1080.bin nor drm.edid_firmware=edid/1920x1080.bin do work currently. X11 later recognizes the correct resolution but has the DPI setting completely wrong (it guesses a 7" Display at 1920x1080). Applications that regard the DPI settings (like VLC v3) are thus unusable. Thank you!
