Surface Pro 4 - External screen keeps turning on/off (black flickering)

It is strange that some of you got a newer driver with 1803. Do you also have an Intel Iris Graphics 540?

I don't have the 540 I have Iris Plus Graphics 640 (the top end i7 model). That could be the difference.

I bought the top of the line i7 Surface Pro 4 when it was released, special ordered with everything maxed out. I have a 540. WTF? When did they start adding 640s to the SP4? And why is this happening in the first place? It was broken, fixed, then broken again... 

If you bought an SP4 when launched, you have 6th Gen i7 skylake with the 540 GPU. In 2017, they launched a new SP4 with the 7th gen kaby lake and the 640 GPU. No WFT, this was published, but it was not significant enough to warrant SP5. A bit like the S version of an iPhone :-)

I have the 2017 with the gen 7 i7.

the SP 2017 is NOT an SP4. While they didn't give it the SP5 designation, they

did not say it had anything to do with not being significant enough an upgrade

to get a version number bump. My opinion is that they were trying to emulate the

Apple folks who don't give version numbers to their Macbooks etc.

Thanks for clarifying, but just as Barb noted, the SP 2017 is not the SP4. And this thread is about the SP4.

Sounds like it is fixed for the SP 2017.

Are there any SP4 owners who have fixed the external screen flicker?

Unfortunately, it's not fixed with the SP 2017 SP4.  Mine was bought just over a month ago and I have the problem.  Iris 640 graphics and core i7 7660U cpu..   The windows 1803 update had no impact.  Driver date is 7-25-2017 and version 22.20.16.4749.  I'm scratching my head wondering how Microsoft hasn't had a driver update for nearly a year for their 640 graphics.

Screen blanks out most after a reboot for the day.  If I leave my surface running over night and turn off the monitor and then turn on just monitor the next day, it's not nearly as frequent.  Just bizarre.

@enady - that really sucks. Mine is total fixed. Here is a dump from my system info

Hi Andy,

My system info differs as follows

Yours:

  System Model Surface Pro

  System SKU Surface_Pro_1796

  Processor Intel(R) Core(TM) i7-7660U CPU @ 2.50GHz, 2496 Mhz, 2 Core(s), 4 Logical Processor(s)

  BIOS Version/Date Microsoft Corporation 233.2110.770, 1/30/2018

  SMBIOS Version 3.0

Mine:

  System Model Surface Pro 4

  System SKU Surface_Pro_4

  Processor Intel(R) Core(TM) i7-6650U CPU @ 2.20GHz, 2208 Mhz, 2 Core(s), 4 Logical Processor(s)

  BIOS Version/Date Microsoft Corporation 108.1926.769, 06/12/2017

  SMBIOS Version 3.1

and there are also differences for boot device, locale, time zone plus smaller variations in memory allocation.

But recent posts have already revealed that a SP 2017 is not a SP4.

And they have also revealed that the issue still exists for both models.

I am now wondering about the bios version. I am not aware that I have ever updated the bios, but the version is newer than my purchase date (June 2016) and yours is newer than 2017 where the SP 2017 must have been released.

Anyone knows how the bios is updated? There is no info in my Windows Update history.

Best regards,

Ena
