3440 × 1440 vs 5120 × 1440
UltraWide QHD against Super UltraWide, side by side.
5120×1440 renders 2,419,200 more pixels than 3440×1440 — 49% more. They differ in shape too: 3440×1440 is 21:9 while 5120×1440 is 32:9, so windows and video fit differently.
The super ultrawide is literally two QHD monitors fused seamlessly — tremendous for sim racing, flight sims, and timeline-heavy work. But it demands a deep desk, a strong GPU, and games that support 32:9. The 34-inch panel fits more setups and more software; the 49-inch is a deliberate lifestyle choice.
