Thank you very much for providing those details, we really appreciate that.
Now, in regard to your inquiry, yes, the processor works with Intel® HD Graphics 4600, and that graphics controller supports 3840x2160@60Hz, and the monitor also supports that resolution.
For Windows® 10 the latest Intel® graphics driver is the one that you already installed, which is 4501.
Since the computer is using both nVidia and Intel graphics, we recommend in this case to use the graphics driver provided by the manufacturer.
I look for SCHENKER drivers, and this is the site I got:
I found a link that has the graphics driver for your laptop, but according to our research, the manufacturer of the laptop is SCHENKER, and this site does not belong to them, so it might be risky to try those drivers, however here is the link if you want to do that:
But, before trying any of those drivers, please get in contact directly with SCHENKER to confirm if those are the correct drivers, also a BIOS update might be needed on the laptop or to re-install the chipset and management engine drivers, on the following link you will see the information to contact them, they should be able to further assist you with this issue, since they provide all those drivers for the laptop:
NOTE: These links are being offered for your convenience and should not be viewed as an endorsement by Intel of the content, products, or services offered there.
Please let me know the results of trying the steps above.
Any further questions, please let me know.
Yes, I have tried the drivers provided by XMG (for the Intel HD 4600, chipset and nVidia) themselves which are found here https://www.mysn.de/secure/userarea/download.asp?KategorienOrder=010;010&show=Support which also are fairly old and did not solve my problem. I also am running the latest BIOS version as I was hoping it might of have been that but unfortunately the issue is still there.
Am I the only one experiencing this issue in this kind of setup(external minidp 4k monitor on a HD 4600)?
Update: The issue represents itself every time I plug an external monitor, and I have to restart the process dwm.exe to fix it.
I also am using 125% DPI scaling along with 3840x2160@60Hz if that has any relevance.
Update 2: I've been doing some further testing.
Steps to reproduce:
-First kill dwm.exe, open a youtube video on loop(In my case a 1080p60 video in Opera) and make sure it runs on the intel HD 4600 and start prime95 on blend test.
-Notice how both the mouse and video play smoothly no matter the location of the mouse, whether it is inside a window or directly on the wallpaper(Make sure you keep moving the mouse)
-Open the Intel HD Graphics Control Panel, go to Display and change the refresh rate(In my case from 59Hz to 60Hz or viceversa, keep resolution at 3840x2160) and click Apply(This is all done while prime95 and the youtube video are playing).
-Your screen will flash black for a brief moment.
-Now try to move the mouse again and notice how both the video and mouse lag as soon as you start moving the mouse on the wallpaper area.
-Kill dwm.exe and notice how everything runs perfectly smooth again independently of the mouse location.
I hope this can help you guys track down this problem.
Thank you very much for letting us know that information, and for providing the steps for us to replicate the issue, I am sure those details will be very helpful for all the peers viewing this thread.
Even though the mouse works fine when you kill dwm.exe, for testing purposes, did you test it with a different mouse?
Now, I just found a link with the specifications of the laptop, and according to it the graphics controller being used on that platform is Nvidia GeForce 880M, here is the link for you to be able to confirm that information:
If that is the case, then the drivers needed are the ones that belong to Nvidia, also if the information on that link is correct there are no Intel graphics drivers involved in this situation, here is the link where you will be able to find Nvidia drivers:
Please confirm the information above.
You mentioned that you already tried the drivers provided by XMG, and that is the best thing to do when you are using a laptop, so, before trying the Nvidia drivers, please get in contact with XMG directly, to check if those drivers will work with your system and to get further technical or warranty assistance.
Any questions, please let me know.
I will try to contact XMG about this to confirm that the drivers provided on their website are the latest (Even though they are from 2015... so I'm not sure of their usefulness if they are the latest) and see what they say regarding using the latest drivers provided on the Intel and nVidia websites.
Yes, I have tried with the integrated touchpad and I get the same exact result(If it has any relevance I'm using a Logitech G502 as external mouse).
Their systems are highly customizable systems where you can pick what cpu and what gpu you want, in my specific case I picked an Intel i7 4810MQ and a gtx 870m.
Although they don't mention it in that link you found, the system uses nvidia optimus, which means it switches between the intel hd 4600 of the i7 4810MQ and the gtx 870m depending on the process.
Dwm.exe is one of those processes that the nvidia panel does not allow me to re-route to the gtx 870m and is instead forced to run on the integrated intel hd 4600(Which is why I keep writing here and not to nvidia).
At the moment I am running again the latest Intel HD 4600 drivers and nvidia drivers as stated in the first post of this thread.
Thank you very much for providing that information, we really appreciate you took the time to let us know those details.
And yes, at this point to contact XMG will be the best thing to do to verify if in fact there are Intel drivers involved in your configuration.
As you mentioned, the Nvidia optimus works with switchable graphics, in this case using both Intel and Nvidia, additionally according to the information about the Dwm.exe, it seems to be your system is working with Intel graphics, but it will be better to confirm that information directly with XMG, just to make sure.
Once we confirm that, we will be more than glad to continue providing assistance in order to try to fix this problem, if it is necessary, we will do further research on this matter in order to try to find a possible solution.
On the following link you will find further information about switchable graphics, please read the last question in there:
Any questions, please let me know.
Hi Janolehuebner: Please submit your inquiry on a new thread, the reason for that is that every scenario is different, even if the same product is being used, so, for us to further assist you to try to fix the specific problem the PC might have, please submit a new thread:
