Which resolution suits a 15.3 inch laptop?

Higher resolution looks sharper but makes text smaller, so you need display scaling. At 15.3 inches, 1920 × 1200 gives 148 PPI and 2880 × 1800 gives 222 PPI. The table shows the Windows scaling each needs.

Sit farther away than the last column and you will not see single pixels. See every resolution in the chart.

At this size, 1920 × 1200 hides single pixels from about 23 in58 cm, 2560 × 1600 from about 17 in43 cm and 2880 × 1800 from about 15 in38 cm. At 225% scaling, 2880 × 1800 draws everything more than twice as big, so its extra pixels go to sharpness, not space. None of them runs at 100%, as text would be too small to read at 18 in46 cm.
