Use higher resolution pictures

Hello, The theme is great, I like it. However, I found a problem. If I browse the website on a large 4K or higher resolution computer, the website image will be blurred due to the low resolution.Especially on the big computer display. My server has sufficient capacity and bandwidth. I want to place larger resolution pictures instead of helping me crop 5333 * 5333px photos to 533 * 533px after uploading. Can this be set in the theme? Or add a new feature, when it is turned on, the larger picture will be used in priority over the quality, rather than the smaller picture in browsing speed Thanks！
