Mini Displayport not working on new Best Buy Yoga 14 (Yoga 460)

Yesterday I purchased one of the brand new Yoga 14s from Best Buy, the one with the pen that is basically a Yoga 460.

 

The Mini Displayport doesn't work. Plugging in a monitor makes the system hang for about 15 seconds, and no display is detected.

 

All Windows and Lenovo software is up to date.

 

I am using a Mini DP --> HDMI adapter, but I have never had any problems with it on other computers.

 

I have ordered another converter cable and will try that tomorrow.

 

Is Lenovo aware of this issue? Is there a fix available?

Bumping this post. Is there going to be a reply from Lenovo? Many other users are reporting the same problem on the Tablet PC Review forums.

Still waiting, this is a pretty serious bug.

Hi.

 

Please post the full model number ... for example I have TP Yoga 14 - 20DM008UUS. But mine has a full HDMI port, so I guess we have different models.

 

Post the full number and let's find the video drivers and BIOS firmware on the Lenovo support site to see if helps you fix your problem.

Thanks for your reply. This is the 20FY0002US. Unfortunately, it is already up-to-date with the latest drivers on Lenovo.com.

Hi

 

Sorry for more trial and error, this is what I will test in your situation to try to rule out a software issue.

 

1) Windows Key + P to turn on the external monitor: I guess that it is not working at all in you case.

2) Mini DP to HDMI cable. I will try at least two different one, just to rule out that the cable is malfunctioning.

3) Try to rule out problems with the external monitor by trying other monitor or project.

4) Check Windows "Device Manager" and be sure that there is nothing there that is not recognized by Windows.

 

I was checking the drivers for your model... here

Does it has an Intel and NVidia video adapters?

 

5) Try updating both, you can use under your own risk DriverEasy to check for new driver on your machines and try to update them. I use DriverEasy from time to time but I know that those are not Lenovo official tested drivers. Or go to Intel and Nvidia site to find newer drivers.

 

If that does not work what I will try to do last, Is to try to boot other OS from an USB or external DVD drive to see if they also have the same problem with the port.

 

Sorry, like I told you it is "trial and error", but I hope it gives you some ideas.

Re: Mini Displayport not working on new Best Buy Yoga 14 (Yoga 460)

Any resolution to this? I picked up a Skylake yoga 14 and I'm not getting anything from the DVI or HDMI outputs on a mini-DP to HDMI/DP/DVI adapter.

 

Drivers are all updated, and I'm using only one output at a time. I've tried the adapter on a Surface Pro 3 and it worked flawlessly, so the problem is with my Thinkpad.

 

Is there any chance that the mini-DP output on these laptops is only DP 1.1 standard? I'm using a DP 1.2 adapter....
