I use a laptop with my TV to game on.
Every time I unplug and replug, sleep, restart, or boot up the TV has forgotten the input, moved it all the way to the end of apps and turned off game mode. I have to redo all these things every day.
Replugging happens often too as the TV says there is no source after waking the laptop from sleep.
Very frustrating especially since there is no input on the new Samsung remote, which is just a basic "feature".
