    Intermittent scrambled display with hd 4000


      I have an Asus Zenbook Prime UX31A with a Core i7 3517U CPU and Intel HD Graphics 4000 running Windows 7 Ultimate 64 bit Service Pack 1, with all current updates installed.  I have been experiencing what appears to be an intermittent loss of sync on the display, which completely scrambles the image.  The only way to clear the issue is to reboot the system, after which it is always fine.  This would seem to suggest a software/driver problem.  There is no correlation with a particular task or app, idle time, suspend/resume (though it never does this coming out of resume), operating temperature, or the amount of time the system has been on.  It can run fine for weeks or have multiple occurrences within one week.


      I updated the original graphics driver from 2012 with the current Intel driver available from Asus which is dated 1/22/2014.  The Intel Driver Update Utility would not allow the installation of any drivers from the Intel site since Asus has evidently modified the driver for this system.  I'm at a loss as to what to do next.  Any assistance would be greatly appreciated.

          Here's an image of the screen when the problem occurs.  Rebooting always restores proper operation.

            It would be good to determine if you get the same issue through an external display, or in safe mode, or BIOS.

            Does it occur if you move (close and open) the lid?

            Did you try updating the BIOS or contacting ASUS about this?

              Thanks for the response and suggestions!  Here are the answers to your questions.


              1. I don't have an external display, but it did happen once when I've used the HDMI output to drive an HDTV.  Since it can go weeks between occurrences and is completely random as opposed to reproducible, I haven't remained in safe mode to check that out.  I've spent even less time in the BIOS.  Is there something specific you would suggest trying?


              2.  Repeated transitions from standby to resume has not created the issue.  As I said in my initial post, it never happens as I come out of standby and that is how I normally turn off the system - by closing the lid.


              3.  I have contacted Asus and they suggested the new graphics driver that I installed, but there are no bios updates that reference graphics.  There are two newer bios versions on their website, and I've asked whether either one of these should be installed.  Still waiting for their response.

                @ hij2001, If you want to try the latest "generic" Intel HD Graphics driver for your system, you can download it here:


                64 bit version


                It does not have any ASUS modifications so some display features of your system may work differently. You can always roll back to the ASUS customized driver however. Extract the win64_153332.zip to a folder on your desktop and use the following instructions to install it.


                1. Login with administrator privileges

                2. Open Control Panel

                3. Open Device Manager

                4. Click on "Display adapters"

                5. Double click "Intel HD Graphics"

                6. Click on the "Driver" tab

                7. Click on "Update Driver" button

                8. Click on "Browse my computer for driver software"

                9. Click on "Let me pick from a list of device drivers on my computer"

                10. Click on "Have Disk" button

                11. Click "Browse"

                12. Navigate to the folder that you unzipped the Intel HD Graphics driver to

                13. Navigate to the Graphics sub-folder

                14. Double click the igdlh64.inf or igdlh.inf file <-- depends on if you have 32 or 64 bit OS

                15. Click "OK"

                16. Click "Next", Driver should now be installing.

                17. If successful, click "Close", Reboot.

                  Thanks for the suggestion and pointer to the new driver.  I had tried installing an Intel generic driver before, but when I attempted the manual install from zip, Windows wouldn't allow me to install it as the current driver was correct.  I think it was because I tried the setup file rather than the inf file per your instructions.  That enabled the install to proceed, for thanks for the detailed procedure.


                  I'm up and runnning, and will provide an initial update on whether this driver improves things in a week or so, as well as whether Asus comes back with a BIOS update.


                  Have a great weekend!

                    Thanks for the suggestion.  I did download and run the tool and the system passed as I expected, which reinforces that the problem is most likely a being caused by a driver issue since a restart always corrects the display.


                    Per my note on the 6th in response to Robert, the new Intel generic driver he suggested has been installed and running for three days without the problem occurring, so we'll see if this trend continues.  It sometimes goes for weeks without failing, so I won't know for a while if this is the fix.  


                    In the interim, I also received an updated driver from Asus, but the Read Me file indicates that this was released in June last year, versus the one from Robert which was released in December.  I'll try this one if the December release doesn't resolve the issue.


                    I sincerely appreciate the suggestions from both you and Robert.  I'll provide updates to this thread as appropriate on whether these suggestions resolve the issue.





                    • 8. Re: Intermittent scrambled display with hd 4000

                      Problem returned this morning while viewing a video.  Once again, restarting resolves it.


                      I thought that I would try the latest Asus driver to replace the generic Intel driver that Robert suggested, but the Intel Graphics Installer indicated that these were older versions than what I have currently installed (which I noted based on the Read Me files in my last post).  The current drivers are HD Graphics 4000 and Intel Display Audio

                      Given that the problem occurs across a number of different driver versions, and Intel Processor Diagnostic Tool indicates that the processor and chipset are fine, this would seem to point to the BIOS as the only remaining cause.  I am waiting for a response from Asus support on whether either of two more recent BIOS versions on their site is appropriate for my system.  In the interim, I restored the BIOS to all default settings per Asus Support's recommendation, although I don't recall ever making changes to the BIOS. 

                      Let's see if this makes a difference.  Stay tuned.

                      • 9. Re: Intermittent scrambled display with hd 4000

                        I have the same intermittent scrambled display issue with an Asus Zenbook..  Rebooting always solves the problem.  I've noticed that when the display is in the scrambled state, it reboots when I remove the power adapter plug from the laptop.  Also, it never has gone into the scrambled state when I'm on battery power.  I'm thinking that there is some interaction with the power pack and the display.  Any advice?

                        • 10. Re: Intermittent scrambled display with hd 4000

                          I've never tried unplugging the power adapter when the screen scrambles, but I've never had the system reboot when I unplug it normally.  That would be an unusual interaction. 


                          I'm now sadly convinced that this is a hardware design issue with the ZenBook motherboard, most likely a race condition.  This is due to the fact that I've experienced the same issue on Windows 7 Ultimate with a variety of Intel and Asus graphics drivers, and it has continued with Windows 10 Pro and at least 2 different driver versions.  I often used the computer directly on my lap, and thought that I may have been restricting airflow and exceeding the temperature spec.  For the last several months, I place the ZenBook on a solid leather bound notepad when using it on my lap to ensure that no airflow restrictions are created, and I still have the problem.


                          I'm resigned to live with this until it gets frequent enough for me to replace the system.  Despite how much I like the industrial design of the ZenBook, I doubt that I will purchase another Asus product.  I'll most likely look at a Lenovo X1 Carbon, or perhaps another UltraBook manufacturer.

                            Hello, hij2001:


                            Thank you for your answer on this.


                            My thoughts on this is that if it happens very randomly and not so frequent, it could be an issue with the screen or the connections of the screen.


                            Have you checked again with the OEM support to get possible new known workaround for thiss?


                            If you require any further information or support, feel free to contact the Intel COmmunities again.

                              Thanks for weighing in!  I don't believe that the issue is with the screen or the connections, since that would be exacerbated by moving the screen back and forth, which has never caused or resolved the issue.  In addition, when the screen loses sync, there is a motorboating sound in the audio as well, which would seem to suggest something in the chipset rather than the cabling or display.  Powering down and restarting the system resolves it without fail.


                              I have been communicating with Asus support, and their best solution is to get an RMA and send it to CA with a 7-10 day turnaround.  This clearly doesn't thrill me.   My assumption is that the repair will be to replace the motherboard, which they estimate at $550 plus $50 for diagnosis and $10 for shipping.  Investing that kind of money in an almost four year old system makes no sense.  Asus suppport claims that they have no information on any design issue with this system, although others in this and other forums have had similar problems. 


                              Needless to say, Im disappointed in Asus support.  Their earlier responses to this issue were always reload the OS, send it in for RMA repair, or other undesirable suggestions.  I really like the system, but I knew support was not a strength of Asus, which was fine because I can do my own support.  My solution will be to wait until the problem becomes disruptive enough that I will replace the system with something other than another Asus, since there are far more ultrabook options now than in 2012.


                              If you do have any additional suggestion, please don't hesitate to share them.


                              Thanks and regards,

                                I understand your concern about this.


                                To narrow down the issue to the possible source of the problem we can check the following.


                                -Is this happening in an external display?

                                -Have you tested the latest drivers available for Intel® HD Graphics 4000?: Download Intel® Graphics Driver for Windows® 7*, 8.1*,10 [15.33]


                                If the issue follows the external display it could be an issue with the screen, I may say.


                                Additionally, it would be helpful if you provide us with the information requested here: IMPORTANT - Required information for reporting Graphics issues
