Hello guys,
I have the european version Samsung UE40JU6550
After the latest firmware updates ( 1213 / 1214 ) i can't view / access the BIOS / F12 / quick boot menu / safe mode, etc
I tried a lot of different cables, convertors, but no go.
My graphic card is GTX 980Ti.
Is there a way to downgrade back to software version 1211 ?
I really need to access the BIOS / quick boot menu / dual boot, etc
What would you suggest ? Any ideas ??
Thank you

no advices ??

no yet for J series

ok, thank you
is there maybe other way to make it work ??

Connect other monitor and do what you need. Just from my experience - all these problems are more related to PC settings (primary secondary monitor settings etc) rather than TV firmware itself. So check your pc and keep fingers away from TV

i already tried with a monitor.
everything works just fine, but i need to access BIOS / F12 / Safe mode / dual boot / on my TV
what am i doing if i have 2 OS / when i need to install / test some Linux live CD ? etc etc etc
i don't want to have 2 displays on my desk. That's stupid.
