I recently purchased a new Samsung external monitor for my desktop. Much to my surprise and chagrin, the remote that came with the monitor also turns on and off the Samsung TV in my office.
I looked online for solutions but didn’t really find any. So, I came up with my own.
In my case, my desk is directly below the wall-mounted Samsung television so this solution works. If you decide to try this and your two Samsung devices aren’t within arm’s reach, this may not work (but I have another solution).
All I needed for this was a towel.
On my monitor and TV, there is a Samsung label at the bottom center of the device. The infrared receiver that captures the signal from the remote is located here.
My simple solution was to take a small hand towel, which I held against that label (lightly) while I turn on or off the other device. The infrared signal from the remote can’t “see” through the towel, so the covered device didn’t react.
Simple and effective.
If you decide to try this but your devices aren’t within arm’s reach of each other, try draping a larger towel over the device you don’t want to turn on or off, being careful to have the towel cover the label while ensuring it’s as close to the device as possible. Just be sure to remove the towel when you’re done as I suspect leaving it covered could cause heat build-up in the device, which has the potential to damage the unit. Again, I haven’t had to try this but I don’t see why it wouldn’t work.
Please remember that while this is what I do, you’re responsible for what you do with this information. It worked for me and might work for you if you try it, but you have to assume responsibility for what you do (or don’t do).
