Before starting a scan, what should you ensure about display and browser zoom?

• A. Display resolution 100% and browser zoom 100%
• B. Display 125% and zoom 110%
• C. Display 90% and zoom 100%
• D. Display 100% and zoom 125%

Answer: (A)

Setting display to 100% and the browser zoom to 100% ensures pixel-perfect rendering for the scan. When the UI is scaled, either by the display DPI or by zoom, element positions and sizes can shift, causing the scan to misread coordinates or miss controls entirely. This makes element recognition unreliable and can lead to false failures or flakiness. Keeping both at 100% eliminates these scaling effects, providing consistent, accurate matching between what Tosca captures and what appears during execution. Other options introduce scaling that distorts positions and sizes, which is why they’re not recommended.
