Intel HD 530 max res 1680x1050

[JSkri]

I have a Dell Inspiron 3650 running Windows 10 with an nVidia 1050 Ti installed. I'm using the GPU for compute, not graphics. I have enabled Intel Multi-display in the BIOS. When Windows 10 boots, it installs the latest Intel graphics driver automatically. The moment that driver fires up, my resolution drops from 1920x1200 to 1680x1050 and cannot be changed back. The Intel driver reports 1920x1200 as an available monitor resolution, but never presents it as an option when selecting resolution. I have only one display, a Dell 2407wfp, connected via HDMI to the on-board graphics HDMI port. The problem persists with VGA. My only option at the moment is to prevent the Intel driver from installing and use the Microsoft Basic Display Adapter.

Any ideas?

voodoodrul: Thank you very much for contacting the Intel® Graphics communities. We will do our best to try to fix this problem.

For this type of scenario what we recommend is to install the latest graphics driver version provided by Dell, version 4542, please look for 'Video" on the following link to install the drivers:http://www.dell.com/support/home/us/en/04/product-support/product/inspiron-3650-desktop/drivers http://www.dell.com/support/home/us/en/04/product-support/product/inspiron-3650-desktop/drivers If the problem persists after that, since the laptop is working with Intel® HD Graphics 530, we can try driver 4849:https://downloadcenter.intel.com/download/27266/Graphics-Intel-Graphics-Driver-for-Windows-15-60-?product=88345 https://downloadcenter.intel.com/download/27266/Graphics-Intel-Graphics-Driver-for-Windows-15-60-?product=88345 As a workaround you can try to get in contact with Microsoft to disable the Windows automatic updates:https://support.microsoft.com/en-us/contactus/ https://support.microsoft.com/en-us/contactus/ I found a link with some suggestions about how to do that: https://www.howtogeek.com/223864/how-to-uninstall-and-block-updates-and-drivers-on-windows-10/ The content on the above site is not controlled by Intel.

Thanks Alberto. Unfortunately, no joy. The neither 4542 nor 4849 solve the problem. I have blocked automatic driver updates, that's okay, but I would like to use the real driver to get reasonable performance. The fallback driver is very slow. I'm guessing it will work just fine if I remove the dGPU, but I need that for compute.

voodoodrul: You are welcome. Thank you very much for providing those results., we are sorry to hear the issue persists.

The driver provided by Dell should work for your platform, another troubleshoot step we can try is to set 1920x1200 as a custom resolution and confirm if that fixes the problem. Other than that the next thing to do will be to get in contact with Dell directly for further technical or warranty assistance:http://www.dell.com/support/incidents-online/us/en/04/contactus/dynamic http://www.dell.com/support/incidents-online/us/en/04/contactus/dynamic Any questions, please let me know.

Custom resolutions won't work unfortunately. It says that 1920x1200 exceeds the available bandwidth (it doesn't). Dell probably can't support this since it's a third party driver issue, and disabling the Intel driver shows the hardware is capable on the fallback driver. It would take hours of support work to make no progress. I think it would need to be recreated by someone on the driver team for anything useful to come of it.
