Know what matters before you buy.

Short, practical English guides for shopping technology in Brazilian stores. Learn the key specifications to compare before following an offer.

Laptops: what to compare

Processor and memory

Compare the exact CPU generation and SKU, installed RAM and whether it is upgradeable. For multitasking, 16 GB may provide more headroom than 8 GB.

SSD and operating system

Confirm the actual SSD capacity, expansion options and included operating system. A Linux model should not be priced as an equivalent Windows configuration.

Gaming requirements

Check the specific GPU, power limits, thermal design and independent tests for the same model variant, not just a shared GPU name.

Smartphones: specifications over hype

Capacity and support

Choose storage based on photos, videos and apps. Check the exact model number, connectivity bands, software support and warranty region.

Display and battery

Consider screen size, resolution, panel technology, charging requirements and credible endurance testing for the precise version.

Total price

Compare the same capacity and condition across listings. Include shipping, warranty and payment-method restrictions in your decision.

Monitors: match the screen to the setup

Resolution and dimensions

Match size and pixel density to your viewing distance and desk. Full HD at 24 inches is a different proposition from 4K at 27 inches.

Refresh rate and connections

Confirm available ports and whether your laptop or desktop can actually output the specified resolution and refresh rate.

Ergonomics and testing

Check height adjustment, VESA support and professional measurements where color accuracy or response time matters.
