Minamaze Theme Slider Maximum Width

It has no maximum width, its width is the size of the screen.

I see.

What image width size should I use to get the best visual results in the slider? I already set the maximum height of the slider to 350 but the slider just shows a pixelated images.

Do you have Google analytics to check which screen size is most popular with your audience?

No, I don’t have.

Then maybe use this as a guide: https://www.w3schools.com/browsers/browsers_display.asp

Thank you.
