How to Choose the Best All in One Computer

The computers All in one are an excellent investment because they occupy less space than traditional tower PCs. In addition, they are perfectly optimized with all the necessary equipment to guarantee an excellent user experience. If you are looking for basic equipment for simple day-to-day tasks, you can find real bargains when it comes to value for money. If, on the other hand, you need more benefits, the price can be increased. Everything will depend on your needs as a user. When choosing an All in one, you must take into account the following aspects:

  • Screen : one of the important aspects to consider should be the screen. You can find models with small 19 “screens or models up to 29”. The small screens are more than enough to surf the internet and even work. If you use your computer to watch games or multimedia content, a larger screen will always be a better option.
  • Image resolution : if you need a high image quality, you can find All in one that offer 4K quality. But the most common will be to find a Full HD resolution of 1920 x 1080.
  • Processor and RAM : The next key factor is the choice of processor and RAM. A more powerful processor or higher RAM will always allow the computer to be faster and smoother. In home computers, a processor like the Intel i3 with RAM 4 may be sufficient. For more advanced tasks, opt for an Intel i5 with 8GB of RAM.
  • Storage : depending on what you need you will find different options on the market, but today it is an excellent option to choose at least a 1 TB capacity hard drive.
  • Reviews : If you normally buy online, you will see a lot of reviews of the product you want to buy, so do not hesitate and always look for negative reviews and if you see many with the same problem, suspect that that model may be defective.

Basically, these are the equipment options that you should consider when buying your All in one computer . The rest of accessories or equipment will depend on the use of the computer.

Which is Better, an All-in-One Computer or Laptop?

  • To choose either of the two, what you must take into account is space and mobility, compared to the lower features and less functionality of laptops.
  • Although you can always take the screen of your all in one and transport it comfortably, you should bear in mind that it will be somewhat larger than the screen of a laptop.
  • Without a doubt, if you are going to use it for long periods of time and do not have to move from one place to another continuously, an all in one pc is the perfect option.
