1440p is a screen resolution of 2560 x 1440 pixels, also sold as QHD or WQHD. That is about 3.7 million pixels: roughly 1.78 times Full HD and 44% of 4K. Samsung calls it a sweet spot for gamers, and it is most common on 27-inch monitors.
1440p is printed on almost every gaming monitor box. Here is what the number means, the pixel math behind it, and which of our monitors use it.
Specs are from each maker’s official page, as of November 2026.
What does 1440p mean?
Short answer: 1440p is a resolution of 2560 pixels wide by 1440 pixels tall, in a 16:9 shape. Samsung’s monitor guide notes that QHD and WQHD name the same resolution, so you will see all three labels on spec sheets.
The number in the name is the height. Full HD is 1080p, and 4K is 2160 pixels tall.
How 1440p compares with 1080p and 4K
Short answer: 1440p has about 1.78 times the pixels of 1080p and about 44% of the pixels of 4K. Samsung calls it the sweet spot for gamers and professionals who want more room without losing sharpness.
| Resolution | Total pixels | Compared with 1440p |
|---|---|---|
| 1080p (1920 x 1080) | 2,073,600 | 0.56x |
| 1440p (2560 x 1440) | 3,686,400 | 1x |
| 4K (3840 x 2160) | 8,294,400 | 2.25x |
More pixels look sharper, but your graphics card draws every one of them each frame. Samsung adds that a GPU stuck near 60 frames per second won’t get the full benefit of a 144 Hz monitor.
1440p is the balance point: sharper than 1080p, with 56% fewer pixels to draw than 4K.
Why 1440p usually means 27 inches
Short answer: pixel density. Samsung suggests 27 inches as a good size for 1440p. BenQ puts a 27-inch QHD screen at about 108 pixels per inch (PPI). On a bigger screen, the same pixels spread thinner.
Our math, using the diagonal pixel count divided by screen size:
- 24-inch 1080p: about 91.8 PPI
- 27-inch 1440p: about 108.8 PPI
- 27-inch 4K: about 163.2 PPI
Our 1440p monitors
Short answer: seven of our 27-inch monitors run at 2560 x 1440. They split into OLED panels at 240 to 360 Hz and IPS panels at 165 to 180 Hz.
| Monitor | Panel | Refresh rate | Response time |
|---|---|---|---|
| Alienware AW2725DF | QD-OLED | 360 Hz | 0.03 ms |
| Samsung Odyssey OLED G6 | OLED | 360 Hz | 0.03 ms |
| LG UltraGear 27GS95QE | OLED | 240 Hz | 0.03 ms |
| AOC Q27G4X | Fast IPS | 180 Hz | 1 ms |
| ASUS ROG Strix XG27ACS | Fast IPS | 180 Hz | 1 ms |
| ASUS TUF Gaming VG27AQ3A | Fast IPS | 180 Hz | 1 ms |
| LG UltraGear 27GR75Q | IPS | 165 Hz | 1 ms |

How we chose
We define 1440p using Samsung's and BenQ's official monitor guides, and list the monitors in our catalog whose maker states a 2560 x 1440 resolution. Pixel counts and pixel density are our own arithmetic. Research-based, not tested in person. Our methodology.
FAQ
Is 1440p the same as QHD?
Yes, 1440p, QHD and WQHD all name the same 2560 x 1440 resolution, as Samsung's guide notes.
What refresh rate should a 1440p gaming monitor have?
Samsung recommends 144 Hz or higher for gaming, and all seven of our 1440p monitors run at 165 Hz or more.
Does 1440p need a strong graphics card?
It needs about 1.78 times the pixels of 1080p per frame, so it asks more of your GPU than 1080p and far less than 4K.
What size monitor suits 1440p?
Samsung suggests 27 inches, and all seven of our 1440p monitors are 27-inch models.
