Windows 10: I want to set an HDMI port to only send audio and isolate the video output to other ports....

I have an NVIDIA Quadro M2000 with as the name implies four DisplayPort DP outputs. I'm using DP > HDMI cables to connect three devices: DP1 out to surround sound receiver to handle all audio. DP2 and DP3 out to dual monitor setup, and DP4 unused. MoBo has an HDMI out that is unused because trying to port the audio there was even more problematic with directing the 5.1 surround sound to the correct port.When it is set up, it is stable and works fine...for one session. However, when I return from standby mode, DP1 is seen as a possible video output, and apps that were previously visible

Force Display Output via HDMI Port

Windows 10 Question: The goal is to display two screens (same video screen) from the computer to two projectors for a presentation using Power Point Slides. Attaching to one projector works fine, but when I attach a HDMI splitter to hook up the second
projector, the computer no longer detects the display and will use the HDMI port as an output.



Thus, can you force a video output from the HDMI port using Windows 10.

 

HDMI port , is it input/output/both?

Hi Ken

On 99.99% of PC's and laptops the HDMI Port(s) are output only, there are some really high-end laptops that also have HDMI input, but they are very rare indeed . .

 

HDMI port on laptop

No. The HDMI ports on the microscope and the laptop are video output only, not inputs.
