Hi @iamwithU,
In revolution slider and another responsive gallery, there is what we called aspect ratio and it’s not just related to the height you applied. With aspect ratio, the height changes as the width change. Example, let’s say your slider has 1036x768 pixel size and displayed on a 1200px screen, it will then scale to 1200x980 ( You can try this tool to https://andrew.hedges.name/experiments/aspect_ratio/) instead of 1200x768.
Now, the issue is, you’re trying to achieve a certain dimension by comparing two sliders given that their settings are different. First one is a full-screen (ignoring the aspect ratio), the others are full-width sliders. And these settings respond to sizes differently in comparison to each other, one ignores the height, one respect the aspect ratio.
It’s easier on mobile since the portrait is almost equal to two squares stacked together. But not on a landscape dimension. Try turning your mobile to landscape and view it, the sizes then changes and no longer half of the first one.
Try making them full-width sliders with dimensions relative to each other (like if first slider’s height is 1000px, then the next is 500px, again this will only work on full-width slider)
Thanks!
