Lenovo L380 Yoga flickering with external monitor (Intel® HD Graphics 620)

[PChri2]

Hello all,

This is my first time that I posting something so please let me know if you need further details or clarifications.

I have a Lenovo L380 Yoga and when i connect an external monitor I got flickering on the external monitor and some times on the laptop's monitor.

I am connected with HDMI cable and I tried using a BenQ monitor and HP monitor.

I have tried different types of HDMI cables.

I have downloaded and tested the below drivers:

I have also tried through BIOS settings on the display section by changing the priority to HDMI port and also adjusting the memory from 256MB to 512MB

I have the latest firmware and BIOS updates from Lenovo website for L380 Yoga.

Finally I have tried all available refresh rates from Intel(R) UHD Graphics Control Panel 50 Hz, 59 Hz and 60 Hz.

I have concluded that I need a compatible Intel HD Graphics 620 drivers, either a new release or on old generic one.

I am not an expert so it may be something else.

Do you have any suggestions?

Hi and thank you for your prompt reply.

Apologize for the delay.

It looks like that after shutting down the laptop for a while it fixed the problem with the flickering.

So the drivers that I have now installed and looks compatible is:

It's is working now without any flickering issues.
