Phaser 2 / CE

Hello teachers! I am a beginner. Load images and draw text on Phaser CE. The picture quality is very blurry. My design draft is 750 × 1334. How can I keep the picture quality clear?

Try either

new Phaser.Game({
  width: 750, height: 1334,
  resolution: 2,
  scaleMode: Phaser.ScaleManager.SHOW_ALL
})

or

new Phaser.Game({
  width: 750, height: 1334,
  resolution: 2,
  scaleMode: Phaser.ScaleManager.USER_SCALE,
  scaleH: 2, scaleV: 2
})
