How to Choose the Best Digital Converter Box

First of all, digital converter boxes aren’t as complicated as they seem. Yes, they provide the conversion of the digital signal and offer many other functions, but in general, are simple devices, and as soon as you realize what their most important aspects are, you will easily find the one that suits you the best.


Things are pretty simple when it comes to the resolution. If your converter doesn’t support, for instance, Full HD, you won’t be able to watch these channels at all, or you are going to be able to watch them in a lower resolution (the largest resolution supported).

In other words, choose a converter that supports at least the 1080p resolution, which is today’s minimum, or if it is possible, a 4K one.


More outputs mainly mean higher versatility. HDMI and Composite connectors are a kind of a standard and most of today’s TVs are making a connection to a digital converter through them. Although the vast majority of converters have these two, still check that before the purchase.

On the other hand, the best digital converter boxes will have many other outputs such as Coaxial, Component, etc. and as mentioned before, more connectors means more options for you.


Although extra features by themselves aren’t the most important and you can live without them, fact is their presence makes the whole device much more valuable and attractive. For instance, Multimedia Player, Parental Control, or a Digital recorder isn’t essential, but can prove to be very handy and therefore, it is good to think through which of the features might be useful and to choose the converter box in accordance to that.
