Mr. Chen gasped. "It's like magic!"
Riya smiled. "Not magic — just Windows settings working with vector graphics."
She checked Windows Display Scaling. Mr. Chen had set it to 150% (recommended for his 4K screen). Vector Q, however, was an older app that didn’t handle scaling well.
Riya remotely connected to his Windows PC. She saw the problem instantly: Vector Q was running, but the toolbar icons were replaced by gray boxes.
She right-clicked Vector Q’s shortcut → Properties → Compatibility → Change high DPI settings .
