Ako je uzrok ovo što ja govorim, onda nije problem u laptopu nego u TV-u.

"Sounds like the monitor is not capable of displaying the basic resolution used in BIOS and only shows when windows has booted up with advanced graphics drivers running"
"Thhe BIOS, POST - IMHO won't show up in external screen. They work with minimal generic display drivers which are capable of lighting up internal display only. For HDMI connected display to work, the Windows & additional system drivers should load."
