Measuring 6.1 inches and featuring a nearly bezel-free, edge-to-edge curved screen, the Samsung Galaxy S10 has one of the largest, sharpest screens ever to grace a smartphone. But by default, Samsung hasn't set the phone at its highest resolution.

Out of the box, your Galaxy S10 uses the middle resolution, called FHD+, mainly to conserve battery life. That said, many users think it's worth the somewhat reduced battery to see photos and video at the Galaxy S10's highest possible resolution.

The Galaxy S10 has three different resolutions you may choose from:

  • HD+ is 1520 x 720 pixels.
  • FHD+ (Full High Definition Plus) is 2280 x 1080 pixels. This is the default.
  • WQHD+ (Wide Quad High Definition Plus) is 3040 x 1440 pixels.

Here's how to change the display to the resolution of your choice, whether you want to set it higher or lower.

How to change a Samsung Galaxy S10's screen resolution

1. Start the Settings app.

2. Tap "Display."

The resolution change takes place immediately. Here you can see how different the same photo looks on the Galaxy S10's display when you switch between HD+ and WQHD+.
