Some more info on models that work and don't work:
I tested bios version 25 on 2 not so old tv's:
Panasonic (plasma): XT-PV50Vt20EA - There is no bios load screen when connected through HDMI
Samsung (lcd): 55” ES8000 Series 8 SMART Full HD LED TV - There is a bios load screen when connected through HDMI
Unfortunately I own the first tv and not the second.
