+### Improve blurry screenshot resolution
+
+If you set a large viewport width and height, you may find that the resulting screenshot appears blurry or pixelated. This can happen because the browser's default `deviceScaleFactor` (which defaults to 1) is not high enough for the large viewport.
+
+To fix this, increase the value of the `deviceScaleFactor`.
+```json
+{
+  "url": "https://cloudflare.com/",
+  "viewport": {
+    "width": 3600,
+    "height": 2400,
+    "deviceScaleFactor": 2
+  }
+}
+```
