I don't see why a monitor would need a firmware update. And http://www.samsung.com/uk/support/model/LT27A550EW/EN doesn't show anything either.
http://www.samsung.com/uk/support/model/LE40M86BDX/XEC shows a 2010 TV and again, what's the goal here? 2010 models were pretty lame in what "smart tv" features were out then. It's not a software issue but back then the CPU, RAM and such were a fraction of current models.
Most folk add a Roku, Samsung (smart) BluRay player to upgrade monitors and TVs.

Dear All,
I have two samsung tv's at home and would like to upgrade them if possible.
I have searched the net for any kind of update software/firmware and instructions but haven't found a thing..
Can someone please tell me if it is possible or not to update them? Cheers
