The screen size of laptops has always been a controversial topic. People familiar with the notebook industry and products also know that the most representative screen topic over the years is undoubtedly the "13-inch golden ratio" proposed by the industry in 2008. At that time, major brands followed suit and launched 13-inch products one after another. Why is 13 inches the most representative? It's simple. The relatively portable body (12 inches is more portable, but the screen size is slightly smaller, while 14 inches is relatively thick and not conducive to mobility) and the screen size that is neither too big nor too small are known as the best size for laptops.

However, with the advancement of technology, the topic of laptop screen controversy and discussion was raised to a new level in 2015. Nowadays, whether it is a notebook product for traditional applications or a gaming notebook product, the screen trend has gradually moved towards 15 inches.

Why is this so?

First, changes in the technology industry have led to changes in form factors. From the smallest mobile phone with a screen to a medium-sized tablet, to a sub-large notebook, monitor, and finally to a large TV, the screen size of products is rising one by one, and the market demand determines the speed of its rise. Mobile phones are moving towards the era of large screens, tablets have reached 12.5 inches, and TVs are even 100 inches. Even if the concept of four screens in one has not yet been popularized, the larger screen size will greatly enhance the user experience. Therefore, as the size of products in the entire technology industry increases, the screen size of notebook products also increases accordingly.

Secondly, in today's era, fragmented time has been occupied by mobile phones and tablets, while the application of notebooks is more limited to daily office and gaming entertainment. For gaming and entertainment, 15-inch products have a better visual experience and a wider viewing angle than 13-inch products. Let's take Dell's most advanced gaming notebook Alienware 15 as an example. The 15-inch one obviously brings a much stronger visual experience than the Alienware 13. At the same time, because the 15-inch has a larger body volume, the Alienware 15 can fit a powerful GTX980M independent graphics card while ensuring the heat dissipation effect, so that large games can still run smoothly with all special effects turned on. While the larger screen brings visual impact, it can also present more dazzling game special effects.

The "little alien" 7000 series gaming laptops, which were very popular last year, have also been launched in a larger 15-inch version this year. They can accommodate dual fans and bring better heat dissipation performance. Users can get a better visual experience without having to worry about the heat dissipation of the machine.

In addition, the surge in screen resolution is also a booster for the screen size to move towards the 15-inch era. 4K resolution is entering people's lives. As we all know, the higher the resolution, the higher the clarity of the picture quality. In games and watching movies, the skin details of CG animation characters and the details of characters in movie videos are clearly visible. On the other hand, with the improvement of clarity, the icons and fonts of system and application software become extremely small, so the advantages of 15-inch screens are highlighted.

This is especially true in another area where notebook products are commonly used - the daily office area. The reason why 13 inches is the golden ratio has been explained in the first paragraph. It is because of its portability, eye tolerance and perfect combination with performance. However, with the rapid development of technology, 15-inch notebook products are becoming thinner and lighter, and they are no longer a problem in carrying. In terms of performance, the 15-inch mold has more space, which makes it easier to fit powerful CPUs and GPUs, and it is also easier to solve the heat dissipation problem. Of course, it provides an excellent experience in terms of screen resolution and visual experience. Speaking of this, we have to talk about Dell's latest XPS 15. The super beautiful narrow frame design gives people a comfortable and broad feeling at first glance. Moreover, it has good performance, with a built-in GTX960M independent graphics card and a quad-core standard pressure processor. It is not only suitable for office work, but also can play many large games. It can be said to be a multi-purpose laptop.

Indeed, as mentioned before, today's 15-inch notebook products have surpassed products of other sizes in terms of weight, thickness, screen resolution and performance, and have also greatly increased their market share. 30% of users have paid attention to and purchased 15-inch notebooks, which also proves that they are popular and becoming the mainstream. In terms of purchasing options, although there are many channels to purchase the required products, we also hope that users can choose a purchase method with fast delivery, patient service, good product quality, and more gifts.
