qHD vs Quad HD vs 4K(UHD):Comparison
If you always wonder about the difference between qHD and Quad HD,4 K
The answer is simple and it's very clear.
What is qHD?
The term qHD stands for Quarter High Definition, which refers to any display packing a resolution of 960x540. That's precusely one quarter of the number of pixels found in a Full HD screen (1920x1080). Older phones like the HTC Desire 601, the Samsung Galaxy S4 Mini and the Sony Xperia M2 have qHD screens.
Of course, qHD screens on mobile phones are thankfully fast becoming a thing of the past, as even basic budget phones now sport a 720p HD screen (1280x720), which is sharper and clearer.
What is Quad HD?
Quad HD is another name for WQHD, which stands for 'Wide Quad High Definition'. Catchy, right?
What this actually refers to is the number of pixels crammed into your mobile phone's screen. The more pixels you have, the sharper movies and photos and everything else will look on your handset's display.
Quad HD screens have a 2,560x1,440 pixel resolution. This is four times the number of pixels you get on a standard HD panel (720p), hence the name. Quad HD screens aren't as sharp as 4K Ultra HD displays, however, as we'll see later.
What is 4K, or UHD?
4K, or 4K Ultra HD to give it its full title, refers to screens with a resolution of 3,840x2,160. This is four times as many pixels as you'll find in a 1080p Full HD (1920x1080) panel.
This is why we think ‘Quad HD’ is a slightly daft name - it’s too easy for people to mistake it for 4K.
4K Ultra HD is in the news a lot at the moment, because the next generation of HD TV broadcasts will be shown at 4K resolution. The likes of Netflix already has some 4K content and soon you'll be able to watch Sky channels in 4K too.
