UK What WQHD means
WQHD stands for wide quad high definition. It describes a resolution of 2560 × 1440 pixels in a 16:9 shape, the same image as QHD and 1440p. The quad comes from the four 1280 × 720 HD images that fit in it, and the W says it is widescreen.
In practice, WQHD and QHD are used for exactly the same monitors. Some makers prefer WQHD to set it apart from lower-case qHD, the old 960 × 540 quarter-HD phone resolution, and from 4:3 or 16:10 formats with similar names. Neither name is a formal standard: no standards body defines these labels, so the pixel count on the datasheet is what counts.
A WQHD screen has about 3.69 million pixels, roughly 1.78 times FHD and a little under half of 4K UHD.
WQHD vs QHD
For monitors there is no difference. A WQHD monitor and a QHD monitor both run 2560 × 1440 at 16:9, with the same sharpness and the same graphics load. The difference is only in the name the maker chose.
Confusion starts when extra letters are added. Each one changes the resolution, so a WQHD screen and a UWQHD or WQXGA screen are not interchangeable, even though they share most of the letters. When replacing a screen, or buying spares to match an existing one, compare the pixel count and aspect ratio rather than the name on the box.
Where the names come from
Display resolution names grew from two separate traditions, which is why the labels can feel inconsistent.
The first is PC graphics. IBM introduced VGA (640 × 480) in 1987 and XGA (1024 × 768) in 1990, and later formats added prefixes to those names: S for super, U for ultra and W for wide, giving SVGA, SXGA, UXGA, WXGA and WUXGA. The WQXGA name for 2560 × 1600 comes from this family, as quad XGA stretched to 16:10.
The second is television. HD (1280 × 720) and full HD (1920 × 1080) came from broadcast standards, and QHD and UHD were named by how many HD or full HD images fit inside them. QHD holds four 720p images and 4K UHD holds four 1080p images.
WQHD mixes the two: a TV-style quad HD with the PC-style W in front. Phone, laptop and monitor makers then added their own plus signs and prefixes, so treat any resolution name as a hint and confirm the pixel count on the datasheet.
The WQHD family of resolution names
The letters follow a loose pattern: W for wide, U for ultra-wide, D for double and a plus sign for a step above the base resolution. The table shows the names you are most likely to meet.
| Name | Resolution | Aspect ratio | Typical use |
|---|---|---|---|
| qHD | 960 × 540 | 16:9 | Early phones and small screens |
| QHD / WQHD | 2560 × 1440 | 16:9 | 27 inch desktop monitors |
| WQXGA | 2560 × 1600 | 16:10 | Laptops, tablets, 30 inch monitors |
| QHD+ | 3200 × 1800 | 16:9 | High-density laptops |
| UWQHD | 3440 × 1440 | About 21:9 | Ultrawide monitors |
| DQHD | 5120 × 1440 | 32:9 | Super-ultrawide monitors |
Phone makers also use WQHD for tall 1440-pixel-wide screens, such as 1440 × 3200, so on phones the label describes the width class rather than a single resolution.
Wide and stretched formats in industry
Industrial screens rarely use WQHD itself. Panel makers concentrate on FHD for most sizes and 4K UHD for large and specialist screens. Wide formats are common, though, wherever a screen has to fit a long space.

Bar-type displays. Stretched displays cut a standard panel lengthways for shelf edges, train passenger information and control desks, at resolutions such as 1920 × 540, 2560 × 1080 and 3840 × 1080.

16:10 working screens. WUXGA (1920 × 1200) adds rows for menus and trend charts. Several of our 24 inch industrial monitors use it in panel mount, chassis and front IP65 formats.

Large detail screens. Where more pixels are needed, defence, surgical and marine screens move to 3840 × 2160 rather than WQHD, including our large format industrial monitors.
Driving a WQHD or ultrawide screen
A WQHD screen at 60 Hz runs over HDMI 1.4 or later, DisplayPort 1.2 or later and USB-C with DisplayPort Alt Mode, and current integrated graphics drive it without trouble. UWQHD at 3440 × 1440 has about a third more pixels again, and DQHD at 5120 × 1440 has twice as many as WQHD, so check the graphics output’s maximum resolution and the cable rating before specifying them.
For HMI and SCADA work, design screens at the panel’s native resolution. A layout built for 1920 × 1080 shown on a 2560 × 1440 panel is either scaled up, which softens text, or left with empty space. On wide and stretched panels, the software usually needs its own layout, because a 16:9 page cannot simply be stretched to fit.
Operating system scaling helps on smaller WQHD screens. Setting Windows or Linux to around 125% keeps text and touch targets at a comfortable size while the panel still receives its native resolution.
Is WQHD worth it?
On a desk, at around 27 inches, WQHD is a sensible middle step. It gives noticeably sharper text and more working space than FHD, with much lower graphics load and video bandwidth than 4K. That is why it suits engineering, programming and design desks.
On industrial equipment the balance changes. The display has to match camera and video formats, stay available for years and survive the site, so FHD or 4K panels with wide temperature, high brightness and sealed fronts are usually the better fit.
Quick answers on WQHD
WQHD: common questions
What does WQHD stand for?
Wide quad high definition. It is a 2560 × 1440 pixel resolution in a 16:9 shape.
Is WQHD better than QHD?
No, they are the same on monitors. Both mean 2560 × 1440, so image quality depends on the panel, not the label.
Is WQHD 4K?
No. 4K UHD is 3840 × 2160, with 2.25 times the pixels of WQHD.
Is WQHD the same as 2K?
Not strictly. Sellers often call 2560 × 1440 2K, but the cinema 2K format is 2048 × 1080, which is closer to FHD.
What is a WQHD monitor?
A monitor with a 2560 × 1440 panel. Most are 27 inches, where the resolution gives sharp text at a normal desk distance.
We supply industrial monitors, stretched displays and panel PCs at the resolution the application needs, and configure and test each one with its computer before it ships.
