I used to have this 2009 Dynex 32 inch TV and every time i pressed a key from the keyboard of the pc tied to it while it was off, the tv turned on like a charm.
I bought myself a 40 in samsung UN40NU7100FXZC and noticed it doesnt, and I wondered if something could be done about it, like adding a push application or something to the registery.
Because if I wake from sleep my sony PS4, the tv wakes without an issue
