Hi Rebecca,
Hope you are well!
If you are using a bigger size image, then it could create problems with the size. Also, the section background image is not screen responsive.
The ideal header image size should be 1920 pixels wide and the height could be according to your requirement.
To make the header image screen responsive, we usually suggest using the image widget in the header instead and add the header image within this widget. Another alternative is that you can create the header image with the logo and event name outside of Cvent (within the header image size specified) and then add it within the image widget in the header. This way, the header will be screen responsive.
However, when using image widget to display the header, you need to select if the image should display as 'Scale-to-Fit' or 'Fixed Background' and check which option fits the best for your header image.

Having said that, I understand your perspective and apologize for any inconvenience. But, it sounds like a great feedback. I suggest you to post this on the 'Ideas' tab of Cvent community.
We encourage you to always submit your ideas or any challenges you face while working with the product. As it also help our Product Development team to review the possibilities and if it works we may try to incorporate such changes in our future releases.
I hope this helps.
