It is a SYBA VGA to HDMI with audio.

You need to set your PC 2nd monitor resolution to a valid "tv" resolution like 1080p or 720p. This will depend on your PC graphics properties for the 2nd monitor. look for 1920x1080 resolution or 1280x720 resolution. After setting the 2nd monitor to one of those, you may need to change/cycle the tv input then go back to it before it is recognized by the tv.

Let me know if you get stuck and before you go please take a moment to submit at least a 3 star rating at the top of this page. Then if you still need help you can reply back and I will be happy to assist you further.

Thanks
Mike

Expert:  Mike G. replied 4 months ago.

isn't that exactly where it should be since you are connecting with hdmi cable....

Expert:  Mike G. replied 4 months ago.

PC on the Tv would be connecting to the VGA port on the back of the tv, which you are not doing.

Are you having website difficulties preventing you from finding the 3 to 5 star rating at the top of this page?
