I have the AMD Radeon RX 570 in a desktop computer, and it works right with my monitor LG 24MK430H.
Thinking in games to play with a Xbox control, I bought a TV LG 50NANO79SNA to connect it to the desktop computer when i want to play, and use it like a Xbox.
It worked really good, but now, when I disconnect the monitor to connect the TV, the PC doesn't give an image...
Things I have tried...
1. Update video card driver
2. Test the HDMI cable
3. Try to find a way to set up the TV
Nothing works, anyone have another idea?
