Monitor Resolution & Pixel Count Comparator
"1440p" and "4K" sound like a small step up from 1080p, but the actual pixel count difference is much larger than it sounds. Pick two resolutions to see the real numbers.
Resolution & Pixel Count Comparator
Standard display resolutions and pure pixel-count math — no per-product claims, just fixed industry-standard dimensions.
2,073,600
pixels · 1920 × 1080 · 16:9
3,686,400
pixels · 2560 × 1440 · 16:9
2560 × 1440 has about 78% more pixels to render — your GPU works proportionally harder at the higher one.

Your GPU has to render every one of those pixels each frame — a resolution with significantly more total pixels needs proportionally more GPU power to hit the same frame rate. Full GPU-matching criteria in our graphics card guide and monitor guide.
