The Nothing Phone 3a 12GB/256GB has a 6.77-inch Flexible AMOLED display with 1080 × 2392 resolution, 120Hz refresh rate, HDR10+, 1B colors, 2160Hz PWM, 800 nits typical brightness, 1,300 nits HBM and 3,000 nits peak brightness. At PKR 153,000, it offers the largest screen in this comparison and a strong outdoor-brightness specification, although its 387ppi density is slightly lower than the Oppo Reno 15 and Realme 15 Pro.
The Oppo Reno 15 12GB/256GB at PKR 160,000 uses a smaller 6.59-inch AMOLED panel with a sharper 1256 × 2760 resolution, 460ppi, 120Hz refresh rate, HDR10+, 600 nits typical brightness, 1,200 nits HBM and 3,600 nits peak brightness. Its higher pixel density makes text, icons and fine details look sharper, while its higher peak-brightness rating gives it an advantage for direct sunlight.
The Realme 15 Pro 12GB/512GB at PKR 145,000 is the display leader in this group. Its 6.8-inch OLED panel has 1280 × 2800 resolution, 453ppi, 144Hz refresh rate, HDR10+, 1,800 nits HBM and 6,500 nits peak brightness, making it the best choice for gaming, high-frame-rate scrolling and outdoor visibility. At PKR 8,000 less than the Nothing Phone 3a, it also provides twice the storage.
The Samsung Galaxy A57 5G 8GB/256GB at PKR 149,000 has a 6.7-inch Super AMOLED+ display with 1080 × 2340 resolution, 120Hz refresh rate, HDR10+, 1,200 nits HBM and 1,900 nits peak brightness. Its display is smooth and bright, but its 385ppi density, 120Hz ceiling and lower peak brightness place it behind the Realme 15 Pro for demanding outdoor and gaming use.

The Nothing Phone 3a is the right choice if you want the biggest 6.77-inch screen for video, reading and everyday use, while its 3,000 nits peak brightness keeps it competitive outdoors. The Realme 15 Pro is the better display purchase at PKR 145,000 because its 144Hz refresh rate, sharper 453ppi panel and 6,500 nits peak brightness exceed the Nothing Phone 3a in every major display measurement.
Verdict: The Realme 15 Pro wins the display comparison, the Oppo Reno 15 is best for sharpness, the Nothing Phone 3a is best for a large screen at a lower price than the Reno 15, and the Samsung Galaxy A57 5G ranks last despite its strong Super AMOLED+ panel.
