Your best solution is probably to write an EDID blob (or reuse one you find somewhere) that provides at least one mode matching your TV's native mode (probably full-HD). Google suggested the following document: http://www.jordansmanuals.com/ServiceManuals%5CLG%5CTV%5CLCD%5C42LB9DF%5C42LB9DF%20Service%20Manual.pdf which on page 13/14 shows the full EDID blob for the various HDMI outputs of the TV. You may want to read that document, convert the EDID blobs to 512 bytes binary files and hell DRM core to use the right one via module/kernel cmdline option: drm_kms_helper.edid_firmware=edid/lg42lb9df.edid or modprobe drm-kms-helper edid_firmware=edid/lg42lb9df.edid where /lib/firmware/edid/lg42lb9df.edid is the 512-bytes EDID blob created according to data from above manual. (note, that will only work for intel, radeon and nouveau drivers but will not work for closed drivers of AMD/nVidia)
This certainly looks doable. That firmware file, should it contain all 4 tables or just the one for the port I'm connected to? Will it matter what order they were in?
