Consider the original resolution of your video clips. Upscaling a low-resolution video will not significantly improve quality, but it can introduce artifacts and blurriness.

Premiere Pro will automatically adjust the sequence dimensions to reflect the new settings. Review your video clips within the sequence. You may need to use the Scale tool (found in the Effect Controls panel) to adjust individual clips and ensure they fit the new frame size appropriately.
