    Intel HD Graphics 4400 SCREEN FLICKERS Only When ON BATTERY @ REFRESH RATE 60Hz

    Birraque

      Dear Intel Support Team,

       

      Like many other owners of Lenovo Yoga 2 Pro (20266 / 80AY) I have been living with this Screen Flicker issue since I bought my computer 3 years ago. The issue also affects other vendor's models like HP, Sony, and Dell and it's now isolated, well documented (with workaround) and I hope it will be fixed in a next driver update for Intel HD Graphics 4400.

       

      It's definitely a very old complaint in the Lenovo Forum with more than 114,330 views.

       

      Please push Intel Engineering Team to fix it ASAP.

       

      1) As described in the guidelines for Graphics questions here is further information about the issue and my specific device:

      Description

      Provide a detailed description of the issue

      Only when ON BATTERY @ 3200 X 1800 and REFRESH RATE 60Hz the screen will be fine for awhile, and then it will suddenly start flickering, turning black for a second or two, then the screen coming back on briefly, then back off, on and on for as long as 60 seconds.

       

      WORKAROUND (Patch): Setting Refresh Rate to 48Hz "when on battery" the flicker will never happen.

       

      NOTE: When plugged on charging the screen flicker will never happen on 60Hz or 48Hz.

      NOTE: Screen flickers often when in use or not (when on battery @ 3200 x 1800 – 60 Hz). It’s not related with any application or screen brightness.

          Hello Birraque,

          Thank you for contacting Intel Communities Support. 

          I will be glad to assist you today.

          Even though the flickering issues you are having may be related to the Intel HD Graphics, we would like you to follow the steps below to troubleshoot your system.

          1. Please load Windows in Safe Mode to check the performance of your system and determine whether the latest Intel HD drivers installed may be the cause of the problem.

          2. You can also roll back the Intel HD Graphics driver. You can find the versions below. 

          - Version: 15.40.26.4474  Date: 6/24/2016
          - Version: 15.40.36.4703 (Previously Released) Date: 6/23/2017
          - Version: 15.40.34.4624 (Previously Released) Date: 3/30/2017

          Please be aware that the driver I am sharing with you is a generic driver from Intel and some features might not be available for your system.

          3. Please check how the power options are configured. We recommend you to increase the minimum processor state to 25% in the Advanced Settings in your plan settings.
          If possible, please send us a picture of the power options configuration.

          4. Finally, try using the latest drivers provided by your system manufacturer.

          Feel free the share the results whenever you are ready.

          Regards, 
          Wanner G.

            Hi Wanner G.

             

            First of all thank you for reply.

            Answering your questions.

             

            1) The current driver (by Intel) 20.19.15.4835 version is very reliable and the best already available so far. It isn't the source of the flicker issue.

             

            2) As detailed in the above table I have had this issue since I bought my Lenovo Yoga 2 Pro (20266) 3 years ago. During this time  I tested ALL drivers (from Lenovo and Intel) without success.

             

            NOTE: As you can confirm in the link below the versions you suggested have already been tested almost a year ago.

            https://communities.intel.com/thread/111349

             

            3) Done, but didn't fixed the flicker. It's ONLY happens when ON BATTERY @ 60Hz

             

            power.jpg

             

            4) As you may have read in #2 above I had already answered this same question earlier. The flicker does not occur only in this model from Lenovo (it's Intel HD Graphics 4400 related).

            How can we handle it?

                Hello Birraque

                According to all the information available and the feedback users have provided since 2014, drivers may not be the source of the screen flickering.
                As I already stated above, Intel HD graphics drivers are generic and some features may not be available for your system. Having said that, we really need to consider hardware to be the cause of the screen flickering.

                In addition, to continue gathering information about your system, please go into your Graphics Properties and send me a picture of the 3D settings. 

                Regards,

                  One more input:
                  Yoga 2 Pro was made with Samsung LTN133YL01-L01 Local Flat Panel (build-in monitor) that support 3200 x 1800 @ 60Hz and 3200 x 1800 @ 48Hz

                  All Intel Core 4500U (Graphics 4400) has "Intel SDRRS Technology" that automatically lowers the screen refresh rate when ON BATTERY to save energy.
                  Could a BUG in this GPU feature be responsible for the screen flicker issue when on battery at 60Hz?
                  (*) Fail when switch 60Hz to lower 48Hz refresh rate

                    Thank you for your response.

                    Please follow the steps below and let us know if the screen flickering issues remain when on battery at the resolution and refresh rate in question:

                    1. Under 3D settings > General Settings, please select Performance.
                    2. Then, under 3D settings > General Settings, please select Quality.
                    3. After that, under 3D settings > Conservative Morphological Anti-Aliasing, please select Override Application Settings. 

                    Also, I am doing more in-depth research to know whether a bug in the GPU feature described above may be responsible for the screen flickering when on battery at 60 Hz. I will keep you updated.

                      Hello Wanner G,

                       

                      If I understand correctly you want that I to test three new scenarios ON BATTERY @ 60Hz:

                       

                      1) Intel HD Graphics Control Panel \ 3D \ General Settings <Performance>


                      2) Intel HD Graphics Control Panel \ 3D \ General Settings <Quality>


                      3) Intel HD Graphics Control Panel \ 3D \ General Settings <Quality>    AND

                          Intel HD Graphics Control Panel \ 3D \ Conservative Morphological Anti-Aliasing <Override App Settings>

                       

                      I haven't tested any of them before so I can take up to three work days to get a reliable result to share.

                          - FLICKER isn't related (or fixed) with VGA driver version (from Intel or Lenovo).
                          - FLICKER isn't related with battery charge level (%).
                          - FLICKER 'ONLY' happen when running ON BATTERY @ Refresh Rate 60Hz (trigger).

                           

                          What's the next steps?

                           

                          Regards,

                            Hello Birraque, 

                            Thank you for the information provided. I appreciate your feedback and suggestions and I really understand the frustration you may be experiencing at this moment.

                            According to the information gathered, the the latest Intel® Graphics Driver version 20.19.15.4835 is very reliable. However, hardware seems to be the source of the screen flickering since you bought your laptop. I also recommend you to contact your system manufacuterer for any releases. 
                            Your feedback is really important when it comes to driver releases, so keep checking our Download Center for any updates and details on fixed issues.

                            Thank you for contacting Intel.

                            Wanner G.

                              Hello Wanner G,

                               

                              The "Ideal Solution" since LFP and GPU can handle 60Hz is to run on battery at maximum refresh rate without screen flickering.

                              Defective hardware doesn't allow to reach a definitive solution.

                              Please technically explain your conclusion that the source of the flicker issue is the hardware (and not on VGA driver). Which faulty hardware device (component) are we talking about?

                               

                              Regards,
