Trouble changing aspect ratio on intel

[GuanYan]

My laptop is dell and it is having a i5-1135G7 CPU with iris xe graphics. Just want to know how to change the aspect ratio to fit to my monitor which has an aspect ratio of 32:9. 

As you can see the aspect ratio is 16:9.

I have also tried with Intel® Graphics Command Center (Beta) but still not get the issue fixed.

the aspect ratio is still fixed 

I supposed it can be fixed using the resolution of 3840x1080 but there is no difference with 1920x1080  in terms of display which is bad. Hope that anyone could help me on this. Thank you.

Dell Inspiron 15 3511 Setup and Specifications

I'm sorry, but the problem seems to be with Dell. This laptop only supports a maximum of 1080p @ 60 Hz 16:9. This is due to the components Dell uses on the motherboard along the way from the processor to the physical connector.
