The fundamental issue would then appear to be that your BIOS is not
listing the TV out as present.  In which case you will want to attach
the vbios (intel-gpu-tools/tools/intel_bios_dumper) and also the opregion
(/sys/kernel/debug/dri/0/i915_opregion). And we can see what the
difference is. The answer may well very possibly be: update your BIOS.
