Black screen when connecting PC or Mac to monitor
Streaming NOW on a PC or Mac and getting a black screen with audio but no picture when you try to connect to an external monitor?
There are a few reasons why this might be happening. For example, it could be due to your web browser’s hardware acceleration feature, or the display or cable you're using not being HDCP compliant.
One of the troubleshooting steps below will usually resolve the issue.
Try these fixes:
- Connect to external monitor first before playing out: The first thing to try is simply hooking up to your monitor before you hit play, instead of connecting once you've started streaming.
- Disable hardware acceleration within browser: In your browser settings, try disabling hardware acceleration. (It isn't possible to do this in Safari, so try switching to another browser instead.)
- Connect directly to your monitor: Try connecting your cable directly without using a USB hub.
- Check your setup is HDCP compliant: Ideally, use the HDMI or DVI cable supplied with your monitor. If you have an old monitor or cable, replace them with newer HDCP-compliant ones. (If you're not sure whether your equipment is HDCP compliant, look for the HDCP logo on the monitor or cable itself, or check the specifications list. Most manufacturers will specify whether or not the monitor or cable is HDCP compliant. You can also try connecting your monitor or cable to an HDCP-encrypted device such as a Blu-ray player or set-top box.)
