Hello,

I just did this as well (moving the refresh rate to 50 Hz in the Intel Graphics Settings).

I seems to work well for me as well.

Many many thanks to you !

Re: P51s external monitor random shut off

I just tested my P51s and on my TV it works fine at 24hz, 50hz is not an option. 59hz still looses connection.

I adjusted this in the Intel setting. So I'm guessing 50hz or lower is the key. My question if what do you do if you can't choose 50hz or lower.

Still not a super reliable option. So far the only reliable option is the USB C to HDMI adapter. I'd like to see them fix it. Nice to see it actually work lowing the refresh rate. Odd how I tried this before and it didn't help, this was many months ago. I'm guessing an update made it better with 50hz and lower?

Maybe an update made this work, not sure.

 

I did try before lowering the refresh rate but I never had the option of 50. Not sure if this is a monitor driver or what but thankfully it is working now.

Dropping down to 24Hz is not quite a good option when I use external monitor as the main display for work...(also happens to me at 50Hz) the flickering problem is quite ridiculous. The only way I can "stop" it from happening is by playing some sort of video in the background on the external monitor. My guess is that the flicker happens while Intel graphics switches over to discrete graphics?

Either way, this is very frustrating and lack of official response from Lenovo is quite baffling. I'm pretty disappointed in ThinkPad quality and will most likely sell this laptop off and get a competing model.

Hi there,

I was probably too quick. It still depends on the monitor I use.

Any way, playing with this Intel frequency improves (the external monitor goes off less often), but doesn't stop the issue.

I have the same issue as many other users have posted. My monitor/projector shuts off constantly. Could Lenovo provide a solution to this annoying issue? Or at least send to us the adapters to overcome this situation, which is quite annoying for those of us that constantly make presentations to large audiences.

My solution is to use a USB-C hub (esp in lieu of buying a $200 Lenovo quick connect dock).. At least the $50 USB-C hub gets me all my connections (HDMI, USB, ethernet) all in one, AND it solves this ridiculous issue of the screen blacking out.. This way my connection at the office is single plug, and mobile I don't need HDMI anyway..

NOTE: this issue only happens when I run HDMI output AND the screen cover is closed (IE: I am at the office using a larger monitor, and don't want the laptop open)

This issue happens to me, regardless if my laptop is closed or open. Perhaps Lenovo must send us the USB-C adapter for free.

I do have the USB-C dock and this issue happens with me still.

I have been tolerating this flickering issue for a while now, but the flickering seems to be occurring more often. Changing the frequency in the intel graphics driver settings did nothing to fix the issue.
