What does qhd display mean

QHD, on the other hand, is four times the standard HD resolution. The typical QHD resolution is 2, x 1, pixels or p. As is the case with all HD derived resolutions, QHD also has an aspect ratio of which is considered wide. The W is there to explicitly state a wide aspect ratio, although it is essentially the same thing as QHD. QHD displays are very common in Android flagship smartphones these days. QHD is also often referred to as 2K because it is half of 4K.

But mostly, 2K refers to a resolution where the larger of the pixel measurements is over pixels. Companies often use these interchangeably and together. UHD, on the other hand, features a aspect ratio and is four times the resolution of full HD. In other words, four times p, four times x pixels, that is 3, x 2, pixels. Having the same aspect ratio means it is backward compatible with other HD derivates. In other words a 2, x 1, pixel display is going to look pin-sharp on a smartphone but won't look so great stretched out across 40 or 50 inches of space.

Just remember a higher number of pixels doesn't always mean a sharper screen, as the dimensions matter too. To start at the lower end, HD is High Definition, and when the term first appeared in relation to television sets it could mean anything with rows of pixels and up - typically that meant 1, x pixels. Full HD upped that to 1, rows and a typical resolution of 1, x 1, pixels.

In the early days of HD television you would see references to both i interlaced and p progressive - the interlaced technology was a throwback to the TV sets of old, where one frame would show the even lines of the picture and the next frame would show the odd lines, effectively halving the number of frames.

These days you'll almost exclusively see p mentioned, if the "i" or "p" are included at all if no letter is shown, it's very probably p. Display resolutions didn't stick at Full HD for long, and the next step up the ladder was Quad High Definition, or QHD - 2, by 1, pixels, the standard for many a flagship phone right now.

You'll often find it on high-end devices like laptops, TVs, and smartphones. QHD is sharper than regular HD, but isn't as clear as 4K — there are battery and cost trade-offs for each to consider before purchasing. Visit Insider's Tech Reference library for more stories.

These are longer than typical mobile screens, giving a widescreen appearance which is better suited to movies. The G6 just needs more pixels to accomodate that extra length.

However, the actual visual difference between the Z5 Premium and the standard Z5 is difficult to spot with the naked eye, as mobile phone screens are so small.
