Update: On July 28th, Yamaha posted firmware updates for many to Receivers. I don't like hot-plugging cables although some have done that, I avoid it. Worth a try to reinsert the cable ensure seated with power off. Or try another HDMI input in case of a suspect or damaged connector. Sometimes this forces a re-detect of the display. Note: Some settings on these Yamaha receivers including 4K output mode options are only available via the "Advanced" setup, accessed from the front panel buttons under the drop down cover.
With receiver off, hold down the "Straight" button and then press power on. Check your Yamaha user manual's Advanced Setup topic for the exact steps. The above may not help, but just things that come to mind to try. I have a receiver that is capable of transmitting 5. I have confirmed that this is possible using alternative hardware e.
Windows PC. When I connect my Mac mini to the receiver, I get video to the projector and sound to the speakers. However, the sound is only 2 channel stereo. I can choose 5.
In the Output tab of Sound settings, the port is also shown as DisplayPort, no other options available. I am running the currently latest macOS, Mojave And I want to live broadcast Wirecast ,however no sound is being picked up, when I connect the canon to the MacBook. Can you help? Nothing works to get video back. However, after about 5 minutes the video signal returns inexplicably. I can still switch my port to Apple TV with no issues with video or audio but when I return to mac mini, my screen is still black. I have a problem with Audio; display works just find and has no issue at all but I have checked all possible options but audio still does not work.
I primarily want it to push secondary screens containing documents or watching a youtube etc. My issue is the fonts on the iMac have all changed, everything is now much smaller. The safari browser fonts, email, ichat, calendar……everything now has much smaller font. Moving a safari browser over to the bigger tv works fine, but the iMac is my primary display in this case and I need to be able to read without a new prescription :.
I have had my Mac Air hooked and working and suddenly now it wont work when I attach it to my tv. I have the correct input and the cables are fine…could this be an OS X update issue? I have not updated Yosemite…. Thank you!! You saved me hours!! So glad I found this.
I also need both the other usb slots for my mbox and ilok. I am having almost the exact same problem as Jason. My computer flashes as well as though it recognizes that something is happening. I do see pages as Option A and Option B above, and I see an option of optimizing the display for a Samsung on my computer, so there is something going on, but no video. I have a MacBook inch, Mid 2. I guess it could be a substandard adapter cable but it could be something else too.

Good stuff. This helped ease the pain. However, it works great now and the picture is very acceptable. Not sure where I am going wrong frustating. But now when I try and connect, the connection of my desktop on the TV screen only lasts for a few seconds, and it goes blank.
It will flick back on for a second, and then go black again for a few minutes. I had the same problem with my Macbook pro and TV. I was worried it was the TV or the Mac, which are both much harder to fix, but it turned out it was the much cheaper Mini Display Port Adapters so just get a new one. Opened my system preferences and then sound, but there is not an HDMI option listed.
Internal speakers listed only. Any ideas?
