Screen Size and Resolution
Choosing the right laptop starts with the screen. The size is important, but it comes down to personal preference. That said, a 13" laptop screen is likely too small for most people, so gaming laptops typically have screen sizes from 15" upwards, with the higher-end models now going up to as far as 18" in some cases! It's worth making sure that you'll be happy with your display - after all, it's the main point of focus for any laptop!
Once you have your screen size picked out, you'll need to consider resolution. This is a big decision as it usually has a direct bearing on how well a laptop will perform! Essentially the higher resolution, the better the image quality, but the faster the graphics card and processor needs to be in order to keep up.
The three most common resolutions are detailed below.
Full HD
Most models will feature a Full HD (FHD or 1080p) display. These are ideal because they won't require the fastest (most expensive) graphics card to run, but are still capable of putting in a good quality and eye pleasing image.
Quad HD
If you wanted to take things further, then a Quad HD (QHD or 1440p) display provides sharper visuals and better overall image quality than Full HD, however, it will need a faster graphics card to run. This resolution also lends itself to providing a better experience than Full HD when the laptop is used for work as well as play - as it will leave more screen 'real estate' for documents and webpages to be displayed.
4K Ultra HD
For the ultimate performance and sharpest image quality, you can get a 4K Ultra HD (UHD or 2160p) display. For most people this will be the point at which you're getting a diminishing return for your money - as anything bar the most expensive models won't have the performance to run games at this resolution. With anything but the largest displays, this resolution will not seem a marked improvement over Quad HD. However, if you're after the very best display quality, this is where you'll find it.
