For some weird reason, my TV remote also turns on my Smart Monitor ! That is very annoying ! I dont want to use the computer when watching TV, and I dont want my TV on when I use my PC ! Really stupid engineering from Samsung ! (32 inch smart monitor and UN55NU6950 TV)
If you don't use the remote to turn the monitor on and off in normal use then just put a piece of black tape over the monitor IR sensor. Or you could change the angle of seperation between the two until the beamwidth of the remote no longer causes crosstalk to the sensors.
