Blue Technology Slide Background with a Glowing Dotted Mesh Wave on Deep Navy

Free blue technology slide background: a glowing dotted mesh wave on deep navy with an open center. HD 16:9.

Created by Elena Gidura · November 2, 2026

This blue technology slide background stretches two glowing dotted mesh waves across a deep blue navy field, one along the top and one along the bottom. I left the dark band between them empty so your title and text sit in the center. Made for tech talks, product demos and data presentations in PowerPoint.
