HD 4000 Lenovo Yoga problem with HDMI out

Hello. I have encountered a weird catch 22 problem with my receiver/projector and the Intel 4000 adapter/driver. I have a Lenovo Yoga 13, win 8 64 laptop, Onkyo TX-SR875 receiver and Optoma HD 82 projector. I updated the driver to the latest from Intel's site. When I hook up the HDMI cable from the receiver to the laptop, the driver automatically sets the adapter at Monitor. At this point I lose the picture on the laptop and I don't see it on the projector. For some reason the only refresh rate that works on my receiver is 50Hz. Since my laptop outputs at 60Hz, I don't get a picture. I can blindly go to clone or extended modes and fix the monitor refresh rate and get a picture. This works as long as I am on clone or extended modes. But, on monitor only mode all displays are dark, so I can't change the settings to enable a picture on my projector. Any ideas

Thanks, gisr

Hi gisr,

I recommend updating the BIOS of the computer. You can find BIOS updates on this link http://support.lenovo.com/en_US/downloads/default.page http://support.lenovo.com/en_US/downloads/default.page

You can try connecting the projector to the computer directly to see if it works fine or not that way.

If the issue persists I recommend contacting Lenovo in order to get more advanced troubleshooting steps.
