Avada not responsive on windows 8.1 ie 11

Hello, my first post here. Not sure if this is the right place to post. My free 6-m support ran out with Avada :wink:
I have a large image in my Avada homepage that is responsive on all devices and browsers apart from windows 8.1 IE 11.
Does anyone have a suggestion? Or a CSS fix for just this device?
Thank you
