Yoga 910 external monitor flickering

I just got my serviced yoga 910 back after the display out usbc mysteriously stopped working. Now whenever I plug into the external monitor, the screen flickers and turns off and on every 5 seconds or so and it's very annoying. I think this problem is exacerbated when I plug the other usb c in for power. I've already updated my display drivers, and was wondering if anyone else had this problem?

Re: Yoga 910 external monitor flickering

Hi there, Grumpy -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

The only troubleshooting step you have not tried is to reset the unit One Key Recovery and then test it before any updates have been applied.

 

If this doesn’t solve the issue then i would have to say that your GPU could be failing.

 

Update us how it goes.

Re: Yoga 910 external monitor flickering

I have the same issue. My computer is only 18 months old. What are the implications for the one key reset on other functions?

Re: Yoga 910 external monitor flickering

For some strange reason whenever my phone is near the usb-c adapter thing the external monitor turns off. At first my external monitor wouldn't go on because my phone was near the adapter when i moved my phone away it turned on and there was no flickering ever.

Not surprising. Phones are radio-frequency transmitters. They're not terribly powerful, but they do have to get a high-frequency signal out of your house and to a receiving antenna which could be a mile away. At point-blank range, that's going to introduce enough interference to wreck about anything that's not shielded.  If you have a table top radio, set your phone on top of it and send a text to someone. You'll see - or rather hear - what I mean. 

 

Of course, I'm assuming cellular or wireless telephone. If you're talking about an old-school wired phone, then you have a different issue. Smiley Very Happy
