Thinkpad T470 external projector flicker via HDMI

Hi all

 

I have a new Thinkpad T470 running Win10 and I have the following problem:

 

When connecting external projector via HDMI, it flicked showing extended screen and then showing "searching input" repetitively.

 

Have anyone experienced this problem? I appreciate your guidance on this

Re: Thinkpad T470 external projector flicker via HDMI

I have that issue on my ThinkPad P51s. As a workaround, I use a docking station at my office and I use a HDMI (from monitor) to USB-C (laptop) connector. I haven't had the problem since using that workaround. Lenovo seems to think the system board needs to be replaced but I don't want to go that route. It's a very ugly and known issue to many P51s users although Lenovo won't own up to it.

And we're back...
