My computer uses a Radeon RX Vega. I have connected three BenQ-Monitors, a Samsung TV, and an HTC Vive. The Vive is only activated when in use.
While all the monitors and the Vive work perfectly together, the TV seems not to receive a signal. After the first Installation of the Graphics Card it worked perfectly. I had to shut down one Monitor, because the Graphics Gard seemed only to support 3 output signals, but then the TV got his signal. Then, randomly, it learned to give out 4 Signals. 4 Output signals are still working, I can use 3 monitors and the Vive. But even with all monitors shut down, the TV does not get his signal.
What I tried to do:
- Check if the HDMI cable (5 m) works. Yes, when connected to my notebook it works perfectly
- Change HDMI Port on the TV. Picture shows up for one Second, then its gone again
- Change HDMI Port on the Computer. No results. All Ports are working, when using a monitor.
- Updating Drivers and Software of the Graphics Card and die TV and restarting both of them. No results.
The PC recognizes the connected Samsung TV. Also the TV recognizes a “PC” as connected. But it does not show any picture from the PC.
Because of my testing I don’t think the cable is broken. Also, I don’t think that one of the HDMI Ports are broken because it does not work on either of them, but other devices work perfectly. So maybe it’s a software problem with the graphics card?
I searched the Internet for solutions, but most time they just tell to replace the cable. I think my problem is more specific and I hope someone can help me here.
And btw, sorry for my English…
