Inspiron 3847 Desktop HDMI Does Not Wake Monitor

This question is not answered

Just purchased an Inspiron 3847 desktop with integrated graphics to evaluate if we should get them for our company.  Connected an ASUS monitor via HDMI and did not get video.  Could not figure out what was going on so connected via VGA instead and it worked as expected.  Ultimately determined that the Inspiron is not sending a wake up signal to the monitor.  Tried the monitor on a different model computer and it worked correctly.  Tried a different HDMI cable with the monitor and the Inspiron but no change.  So it means that using an HDMI monitor on the Inspiron 3847 one has to turn on the monitor after the computer is started in order for it to connect via HDMI.  Checked to see if there was a BIOS update but I have version 2 that was just recently released.  Any suggestions on how to make the Inspiron wake up the monitor when the system is powered on or taken out of sleep mode?

  • Well thanks for all who may have looked but could not think of a solution.  This system will just go back.  If it can't wake up an HDMI monitor then it is of no use to us.  Dell support blamed the monitor and ASUS blames the HDMI card noting that the issue occurs before the system even boots... meaning it is a fundamental hardware issue.  Perhaps Dell will fix it with the next BIOS update.  Unfortunately for Dell I don't want to be a beta tester for Dell's new desktop.

  • Thought I would try contacting technical support again... but just wasted more time. 

    No suggestions were made whatsoever. 

    Only said 'since it is an out of box issue to contact customer support.' 

    I have contacted customer support via the email request for to return the system. 

    Dell computer fail.  Dell technical support fail.  Dell forum fail.  Dell technical support fail again.

  • Three days later and no response from dell after completing the form on to request to return this machine.  

    I did receive an email confirmation staying  that they would contact me in 24 hours But nothing since.

    is this a new way for Dell to make a bad situation worse?

    Does anyone have a suggestion on how to proceed other than calling my credit card company to dispute the charge?

  • 13 days later Dell finally responds to the 1/22/2104 return request summited on They did send out an email reply on 1/22/2014 that said they would contact us "within the next 8 hours" so obviously they did receive the request... And yet today's message did not include any instructions on where to ship the defective computer or include a return shipping label. We are poised to replace all the desktops in our office and Dell just showed us who we should not purchase from. Not just because the Dimension 3947 has a problem with the HDMI port, but because their customer service is non-existent, as is the help from the community forum.
  • Thank you for taking your time to write up about Dimension 3947's problem.  

    I have the same system for about two months and have been using the VGA cable all this time. 

    I am in the process of switching to HDMI cable and you have save me some time with

    the DELL support.

  • In fairness you won't get anywhere talking to people like you do.
