Phaser3 pixelated on desktop

The images look fine on the phone, but when it’s on desktop I resize them and they get all pixelated. Like described here Resize image = losing quality - Phaser 2 - HTML5 Game Devs Forum . I searched a lot but can’t find a way to make the images look crisp on desktop. I need to scale them down on desktop but they become pixelated if I do so ;_;.

Have to use larger game dimensions.
