Re: P51s external monitor random shut off

2018-04-02, 12:37 PM

I too have this issue where the screen flickers using HDMI out, no matter if I only use dedicated nVidia or Intel from the control panel. However I'm not sure if the HDMI port is always nVidia or not. I have ignored the issue primarily because the USB C to HDMI works great without issue for simple power points which is it's primary function. I'm not sure if nVidia goes thru the USB-C for performance of gaming. Regardless the port is there and it should work, especially since there is no VGA. I can't believe I'm here checking it many months later and there is still no resolution. If it's a hardware problem there should be a recall to fix it, or if it's a warranty issue I need to ensure it's still there to cover it. If it's a software issue I do not know what we're waiting for. I'd think there would be a Lenovo update to fix this. BIOS or driver-wise. - I do not use the dock at all so I can't speak for that. I have a P51s.

Re: P51s external monitor random shut off

My external monitor just started doing this. I did a Lenovo Update and it installed new NVIDIA Drivers (dated Dec 2017) then the external monitor (connected via HDMI) started shutting off after a few seconds of the focus of the machine not being on it.  I tried to roll back the NVIDIA drivers but it didn't matter, it still kept doing it. I modified the power settings still no good. 

 

Any Suggestions?

Hello, hard to say.

Today we do not have the opportunity to work normally with an external monitor. I did not buy a laptop with the option of connecting the docking station.

 

New update from 05 Apr 2018 [NVIDIA Optimus Display Driver (23.21.13.8875/23.20.16.4905)  and Intel Graphics Driver (23.20.16.4905)] do not solve problems.

I do not have a dock either. This is direct hdmi to the monitor or TV. Same result.

I have this problem too.  It looks like it has been around for a long time now.  Has there been any movement from Lenovo?  I've put a call in to them but haven't heard anything.  This is a terribly annoying problem.

I have the exact same problem. No dock. Latest drivers. HDMI connected monitor goes blank for 1 or 2 seconds. I have tried ASUS and Dell monitors and both have the identical issue. When I connect my Yoga Thinkpad using the same cable / monitor(s) I do not have the issue.  Based on the discussion in this thread, this must be a hardware issue.  I have returned my P51s twice for this issue. Both times they report that the mother board was replaced, but the problem remains within 2 days of its return. I'll be calling the service center tomorrow as the are already closed today.

P51 Xeon and Quadro M2200; happens several times a day while docked at the office. Doesn't matter if I'm booted Win10 or Kubuntu18.04.

So is Lenovo going to issue a recall when they figure out what is wrong?

Or can they fix this with a bios or software update? I dont know if this is hardware or software.

This seems like a major oversight as the main video output.
