What is 1440p resolution?

1440p refers to a display or video frame that is 2560 pixels wide and 1440 pixels tall (2,560 x 1,440 = 3,686,400 total pixels), progressive scan, at a 16:9 widescreen aspect ratio. It is officially called QHD (Quad HD) or WQHD because the 1440-pixel height is exactly double the 720p standard, giving four times the pixels of 720p.

What bitrate should I use for 1440p?

YouTube currently recommends 16 Mbps for 1440p SDR uploads at 24–30 fps and 24 Mbps at 48–60 fps. Those are upload recommendations, not universal quality targets. The right bitrate depends on codec, frame rate, motion, bit depth, encoder settings, and the destination platform.

How much storage does one hour of 1440p video take?

At a 16 Mbps video bitrate, the decimal estimate is 16 x 3600 / 8 = 7,200 MB, or 7.2 GB per hour. At 24 Mbps it is 10.8 GB per hour. Audio tracks, container overhead, and variable-bitrate behavior can make the actual file slightly different.

Is 1440p better than 1080p for gaming?

1440p offers 78% more pixels than 1080p, delivering noticeably sharper image detail and better anti-aliasing at the same physical screen size. The trade-off is higher GPU load — a GPU that targets 144 fps at 1080p may only reach 100 fps at 1440p in demanding titles. For 24–27 inch monitors, 1440p is the sweet spot between sharpness and performance.

What is the PPI of a 1440p screen?

PPI depends on the physical screen size. A 27-inch 1440p monitor has about 109 PPI, while a 24-inch 1440p panel delivers roughly 122 PPI. Use the calculator on this page to compute the exact PPI for any diagonal size.

How does 1440p compare to 4K in file size?

4K (3840 x 2160) has roughly 2.25x more pixels than 1440p (8,294,400 vs 3,686,400), so at the same quality level 4K files are approximately 2–2.5x larger. With efficient codecs like H.265 or AV1, the ratio narrows, but 4K still demands significantly more storage and bandwidth than 1440p.

What aspect ratio is 1440p?

1440p (2560 x 1440) uses a standard 16:9 widescreen aspect ratio, the same as 1080p and 4K UHD. Ultrawide 1440p panels (3440 x 1440) use a 21:9 ratio — those are a separate standard sometimes called UWQHD.

Is 1440p the same as 2K?

Not technically. The DCI 2K cinema container is 2048 x 1080, while standard consumer 1440p is 2560 x 1440. Because 2560 horizontal pixels are closer to 2.5K, QHD or 1440p is the clearer name even though some retailers loosely call it 2K.

Does 1440p require HDMI 2.0 or DisplayPort 1.4?

There is no single answer based on resolution alone. Required link bandwidth also depends on refresh rate, bit depth, chroma format, timing overhead, HDR, and whether compression such as DSC is used. Check the monitor, GPU, cable certification, and desired mode together rather than relying only on the interface version label.
