Screen size is one of the important things to consider if you are planning to buy a laptop. To simple understand the screen size, it is a distance measured from one diagonal to other diagonal and drawling a line to join them. Laptops screen is usually measured as small or to large screen size. Screen size has a great effect on buying decision of the customer and important thing is the purpose you are using the laptop. In an interview with John Jacob the director of marketing research of notebook published in PCMag.com says that gadget like smartphone or laptops are usually do the same performance either it is small or big. But as we all know that big screen always cost more and it has always a more clear and profound effect on watching any entertainment stuff like movies or playing games.
With display styles, with a little 1 or 2 inch difference can bring a significant difference with regards to its viewing experience. If we consider the example of Dell’s XPS 15 or Dell Inspiron 17R have almost similar specifications, but the Dell’s XPS 15 has a 15.6-inch screen size and weigh 6.14 pound, while the Inspiron 17R provides a 17.3-inch screen size and just weigh 1 pound more. Although it doesn’t not sound like a huge one but a laptop with all its accessories and charger is quite significant if you are carrying it in your side bad all the time. In standard of Stanford University, they consider the laptop bag weight over 10 pound is critical and cause neck damage.
How resolution matters?
Display quality is calculated in pixel, length by size. Higher-resolution displays provide crisper image quality, which matters if you look at movies online, play specific games or modify photos frequently. Bigger displays usually have better solutions and provide longer watching ranges than smaller ones at the same quality. That mean you can keep a small-screen laptop very close to you or sit close by for a movie, but you can watch clearly in a distance with big screen with the same resolution.
Relationship between aspect ratio and screen size
Most of present-day netbooks designed toward informal use or multi-media watching come with a broad-screen with an aspect ratio similar to television like 16/9. This not only improves display size by about 25 percent by length, and also affects the size and weight. If you want to use your laptop mainly to play games, a 16/9 display provides the biggest area of watching, which is most important for shooting for the first person player.
Conventional 4/3 aspect ratios are commonly used for business-oriented function, and still appear on a few designs promoted for home customers. The small laptops are mostly lightweight and option for creating records charts and graphs and helpful for presentations. It is also easy to project them with all sorts of projector.
Fundamentals of power usage
A bigger display uses more energy, which impacts battery life and energy usage. Laptop like AS7750G-6857 from Acer having 17.3-inch screen size, usually remain charged for 3 hours after fully charged and consume a 90-watt of electric current, while the similar laptop from Acer model number AS5755-6647, with a 15.6-inch display, provides 4.5 hours activity and while use only 65-watt energy. So the concept is if you want to use your laptop without charge for long time, just choose the laptop with small screen size.
