HDMI not working on Ideapad s540-14IWL

2019-10-03, 7:14 AM

I purchased a new Ideapad S540-14IWL recently but couldn't find a way how to connect a secondary display via HDMI. I use Windows 10 Pro.

 

So far I've tried the following:

- using different monitors;

- using different HDMI cables;

- installing newer and older Intel VGA drivers;

- going through the Windows 10 video troubleshooter;

- switching off the laptop and/or the monitor and powering them in various sequences (as suggested in a few articles I found on the Internet);

- tried to switch to the second display using Win+P, of course.

 

No matter what, Windows is not able to detect a connected display (even after I manually push the 'Detect' button). The display itself finds no signal.

 

Surprisingly, the Lenovo diagnostics utility couldn’t identify a problem after running both the Display and the Display Interface tests. The laptop is flashed with the latest BIOS.

 

I read other Lenovo models have similar issued when AHCI mode is selected in the BIOS rather than RST. However, switching to RST comes with a warning that the controller change will result in all the data being erased, which I can't afford. 

 

Any help on that issue will be appreciated.

 

Solved! See the solution

I can verify that changing to rst and enabling uefi solved the problem for me on the s540 14iwl. Far from ideal but as a programmer I have to use an external monitor. BTW, is your bezel also not glued 100% properly to the screen?

I got the same problem on 3 identical machines but the price was too good to let it go.

This issue exists only in Intel S340 versions. I checked my HDMI on the S340-15API and it works with ACHI mode in the BIOS.

Thank you, mulic3, for your reply. 

I hope Lenovo will fix this issue in a future BIOS update. HDMI is not critical for me at the moment but sooner or later I will need it. 

I will check in the meantime whether a Type-C to HDMI adapter will do the trick.

 

And no, my laptop does not suffer from the bezel not being glued to the screen. Apart from the HDMI problem, the laptop is otherwise flawless.

I just solved this issue with help of previous replies. After installing Windows and all updates and drivers (since I bought a freeDOS) I could not get the hdmi to work. After reading this thread, I went into BIOS settings, under BOOT, and changed "Legacy Boot" to "UEFI". Started up the Laptop and hdmi was working perfectly!

This solution(changing the BIOS from legacy to UEFI) solved my HDMI problem.....I just bought my Ideapad 1 14 not too long ago, and it was a surprise for it not to connect to HDMI properly.I upgraded Windows to 2004, but could not figure out the issue until I came upon your solution.

THX!
