Hide Masonry Gallery Title and Expert Caption only on Mobile

Hi
Re: https://signs4business.com.au/gallery/

In a Masonry Gallery, how do we have titles and or exert Captions show on larger screen devices and not on Mobile (small screen devices)
At the moment the Caption at the bottom of the image is permanent when looking on Mobiles, regardless if set to ‘Display on mouse over’ or Not to Display on mouse over’
The issue is that half the image permanently covered by the caption. And if you turn it off then you also turn it off when looking on larger screens.

Your help would be greatly appreciated
Cheers Dave
