Hi,
About this question, please go to Appearance → Customize → Featured Slider → General: select the image size you want to display on mobile at the "Custom Image Size on Mobile" option field.
There is no image display perfectly on all devices. The image on the slider is displayed as background image cover style. If you want to show the full image, you can try to use this CSS (Appearance → Customize → Custom CSS):
.featured-area .penci-image-holder {
background-size: contain;
}Regards,
PenciDesign.
