Troubleshooting Samsung TV Input Signal Plus Issues
So, I was trying to get the 4k 120hz HDR goodness on my Samsung TV when I connected my PC to it, but I found out that the only way to do that was by enabling Input Signal Plus. But, here’s the thing, as soon as I turned it on, the screen went blank and I got no signal. It was super frustrating.
But, when I turned Input Signal Plus off, the screen came back on. It turns out that I had an old and incompatible HDMI cable.
