Although in the world of tablets the Quad HD screens They have a longer trajectory, their arrival in recent times to smartphones and phablets, has only fueled the debate about its usefulness, even though it seems that a mobile device can no longer be considered really high-end if not It uses and the most reluctant manufacturers have been under a strong enough pressure to make the leap. Are they right to resist? Are Quad HD screens a useless improvement?

The utility of Quad HD screens tested

We usually comment whenever we refer to theThe fundamental aspects to consider when choosing a tablet and, more specifically, to value which one has a better screen: the picture quality yes it improves with the resolution, but from a certain point, the improvement is minimal, simply because the human eye It has a limit on what it can perceive. What is this limit? Well, keep in mind that it varies with the size of the screen and the distance at which we use it, but for a tablet, experts have put the 200 PPI as a benchmark of what can be considered sufficient, which means an HD resolution for a 7-inch tablet and Full HD for a 10-inch one.

But what happens in practice? Do users really appreciate the higher resolution of a Quad HD screen? This is what you have tried to determine a experiment in which they have shown iFull HD and Quad HD resolution images on a Quad HD screen, first, and images with Quad HD resolution in Full HD and Quad HD screens. In the first test, about 80% of the subjects were able to distinguish between Full HD and Quad HD images, but in the second the percentage fell to 50%. Despite this decline, it is clear with these results, it is clear that a majority of users would benefit from a screen with more resolution.

Those responsible for this small experiment clarify that the success rate of the first test depended to a large extent on that the subjects were allowed to get as close as they wanted to the screen, something that must be taken into account because, as we said, the distance to which we usually use the device is a fundamental factor when assessing the usefulness of a higher resolution. It must also be said, however, that the test was performed with smartphones 5-inch, in which the required pixel density is lower than in the phablets and, of course, that in the tablets. If we join this to the fact that the success rates they are, in any case, quite tall, it seems that the conclusion It is finally positive: a tablet with an HD or Full HD screen, depending on the size, may be more than enough, but most users will appreciate the improvement with a higher resolution screen. A separate matter, of course, is whether the difference in price may or may not be worth it to everyone.
