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.

Read the Monitor Buying GuideWhy this matters for your GPU
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.
Frequently Asked Questions
Why is 4K so much more demanding than 1080p if it's only "double" in each direction?
Because pixel count scales with both width and height together — doubling each dimension quadruples the total pixel count, not doubles it. That's why 4K's 8,294,400 pixels is 4x 1080p's 2,073,600, not 2x.
Does a higher resolution always need a new GPU?
It depends on the resolution gap and your current GPU's headroom at your target frame rate — check our graphics card buying guide to match GPU tier to your chosen resolution.
