ilpincy, Thank you very much for joining the Intel® Graphics communities.
You mentioned the laptop is working with Intel® Iris™ Graphics 540, I was looking in our web site for graphics drivers for it, and the results I got are showing different versions from the ones you installed, maybe those drivers are not the proper ones for your laptop. Since you already tried drivers 4531 and 4627, we can now try the following drivers
Please let me know the results of trying the drivers above.
Any further questions, please let me know.
Hi, ilpincy, You are welcome, perfect.
I was also checking the specifications of the laptop, according to that information it says it works with Intel® HD Graphics 520 or Intel® HD Graphics 540, those graphics controllers when it comes to graphics drivers are different from Intel® Iris™ Graphics 540, so:
Are you sure the laptop is using that graphics controller?
I can always confirm that if you could please provide the model of the processor?
Here is the link for you to check the specifications:
Any questions, please let me know.
Sorry for taking so long in trying out the possible solutions! Eventually I managed to solve the issue with the help of Dell.
The trick was to update the BIOS, as well as all of the chipset drivers available on the Dell website for my laptop. After doing this (BIOS first, chipset next), the latest driver offered by Dell indeed worked as intended.
I guess there's some funny interaction among drivers that creates this issue when the versioning is not exactly right.
Thank you for your support!
Hi, ilpincy, No problem at all, excellent, it is great to hear the issue got fixed by doing a BIOS update and installing the chipset and graphics drivers from Dell, we always recommend to use the drivers provided by the manufacturer, that is why I wanted to confirm the model of your device, the laptop should work with no problems from now on.
Any other inquiry, do not hesitate in contact us again.
