Re: Yoga 2 Pro + Windows 10 = External Monitor not working via micro HDMI

2015-11-30, 22:43 PM

I zapped the DPTF option in BIOS. Sill my micro HDMI in Yoga is not working. Very stressful. How possibly Lenovo did not release any patch so far?

Re: Yoga 2 Pro + Windows 10 = External Monitor not working via micro HDMI

I've had my Yoga  Pro for a year and a half connected to a DELL ST2410b monitor. It worked great until yesterday. Yesterday the DELL screen went dead while I was using it. I got message "Your PC can't project to another screen", "Try reinstalling the driver or using a different video card". I tried evrything I could, rebooting, killing power, restarting, etc. - nothing ccrrected the problem.

This morning I decided to join and look at the Lenovo forum and while signing up, the monitor popped back on. I have no idea what caused this to happen, but it appears that others have had the same situation happen.

I've found the fix to get the second Monitor to work via HDMI.  Actually it is not a fix but a 'patch'. 

 

You need to roll back the VGA driver.  You need to download the following from the Lenovo site:  Intel VGA Driver 10.18.15.4240.  It is about 83.9 MB.

 

Run that and click 'yes' to replace your newer driver.  The process takes about 30 seconds, keep clicking 'yes', 'accept' etc.

 

Then your next monitor works like before!

 

The problem is that sporadically, at least once a day, your Yoga will run a self-update and re-install the newer (i.e., broken) driver.  And then you have to do this process again.  I just keep a shortcut on my desktop to run the older driver install.

 

It is a very minor annoyance to keep my second monitor working, but takes less than a minute of my time.
