I’m trying to create a template for posts’ featured image, but I’m struggling to get the latest post’s feature image to not get all blurry on my homepage. When I look at my website on my monitor, the featured imaged is 1140×512. I’ve tried uploading media at that image size and larger, but no matter what size I upload, the image that’s selected is a 850×382 copy of the image and it’s then stretched to 1140×512 and thus looks blurry. When I shrink my browser window and the featured images are resized to smaller sizes, they look fine, but when I have my browser window maximized I wind up with a less than ideal looking featured image for my latest post. Is there anyway to get the post featured images above 850×382 on my homepage?
