1366 × 768 vs 1920 × 1080
WXGA against Full HD 1080p, side by side.
1920×1080 renders 1,024,512 more pixels than 1366×768 — 98% more. Both are 16:9 displays, so content fits identically — the difference is pure pixel density.
If you're weighing laptops, this one isn't close: Full HD fits half again as much text on screen and stays sharp where 1366×768 looks coarse, and the price gap has all but disappeared. The older panel survives only at the very bottom of the market — treat it as a red flag on anything but the cheapest machine.
