    Laptop sometimes doesn't recognise TV via HDMI


      Hi everybody,


      didn't find a solution in the Search, so maybe you can help me.

      Provide a detailed description of the issue AND 'does it fail every single time, or only sometimes?' If you can offer a % rate please do.

      I connect the TV using a HDMI cable (already tried different cables). If I am doing this in a bad timing (e.g. during a small time-window while the Laptop is booting Windows, I don't get a signal on the TV. But if this happens, only deactivating and reactivating of the Intel grafics in device manager helps. No rebooting of the Laptop or TV helps. It also does not detect the TV at all in the configuration panel or Intel HD Graphics panel. Only TV switches from "No cable connection" to "No signal" when I plug in the cable.

      Hardware (HW)

      Brand and Model of the system.

      One K56-3O2, i7 4700MQ, Intel 4600 HD grafics

      Hybrid or switchable graphics system? ie Does it have AMD or NV graphics too?

      NVidia Geforce GTX 765

      Make and model of any Displays that are used to see the issue (see note2 below).

      LFP = Local Flat Panel (Laptop panel)

      EFP = External Flat Panel (Monitor you plug in)

      Samsung UE32J6250

      How much memory [RAM] in the system (see note2 below).

      8 GB

      Provide any other hardware needed to replicate the issue.

      ie: Cables&brand, cable type [vga, hdmi, DP, etc], dock, dongles/adapters, etc

      HDMI Cable brand unknown

      Tried several cables already

      Hardware Stepping (see note1 below).





      Software (SW)

      Operating System version (see note2 below).

      Windows 7 Professional 64bit

      VBIOS (video BIOS) version. This can be found in “information page” of CUI (right click on Desktop and select “Graphics Properties”.


      Graphics Driver version; for both integrated Intel and 3rd party vendors (see note2 below).

      SW/Apps version used to replicate the issue.



      Single display, clone, or extended (see note2 below).

      None works

      Display resolution & refresh rate setting of each display (see note2 below).

      LFP: 1920x1080 (32 bit) (60Hz)

      TV: 1920x1080 50 Hz

      AC or DC mode, i.e. is power cable plugged in or not?


      How to repro

      Please provide steps to replicate the issue.  Thesesteps are very crucial to finding the root cause and fix.

      A screenshot to illustrate the issue is a huge plus. Avideo of the failure is even better! Attach to the post or provide the YouTube link.

      1. Start tv

      2. Plug in cables

      3.Nothing happens


      Hope you can help me,

          Hello Pygo,


          Thank you for joining the Intel communities.


          Did this configuration work before or it never worked?


          Please try installing our generic graphics driver for the Intel® HD Graphics 4600, you can download it here:

          Download Intel® Graphics Driver for Windows 7/8.1* []

          If that does not work, have you contacted your system manufacturer for further troubleshooting?


          Best regards,

            Hello Ivan,


            I bought this TV on 20th of January and since then I have this Problem. But like I wrote in the problem discription it only occurs sometimes (lets say 25% of the cases I turn on my Laptop).


            I installed the driver linked in your post several times and it's the one I am using actually. I also tried an older Version on the Intel hompage, a Version from the manufacturer-homepage of the laptop and the Version Windows Update installs on my PC. All versions have the same Problem.


            My older Laptop with a NVIDIA only grafics card never has the problem to detect the TV.


            Hope you have an idea on what I can do/provide more Information so we can fix this problem, cause it is really annoying to reactivate the grafics-adapter in device-Manager.


            Thanks for your help.


            Best regards

              In this case if you have problems with our generic driver and your system manufacturer driver then you should contact you system manufacturer for further support to see if they have a solution for you.


              Are you using any adapters? If yes, have you tried using straight connection?
