6 ultra hd 40-inch+ monitors review: monstrous monitors

Not every ultrawide is also suited for home use



While most small-monitor loving consumers can eventually get used to a 27- or even 32-inch model, this proves to be a bigger challenge at 40-inch and bigger. These monitors are truly monstrous, which means that they can only be used while sitting at a small distance from them, else your neck would not enjoy the experience. 

With an upper edge well above 60 cm it is impossible to position your eyes at that height (as ergonomic advice usually recommends) while at the same time sitting at your desk properly. This means slightly more backward in order to have a better overview. This is also the primary purpose of this type of monitor: applications in which a great deal of information must be visible at once. Think of video editing with the many tools involved, stock exchange information for stock traders, or images from a large number of security cameras, to name a few examples. For this reason all of the models that we test in this article also support so-called Picture-in-Picture (PiP) and Picture-by-Picture (PbP) functionality, which allows you to display two or more different sources simultaneously. 

You should not imagine too much when it comes to the pixel density of this type of monitor: it is comparable with full hd at 21.5", namely 102-110 ppi. You get more work surface rather than extra sharpness. For daily productivity such a high monitor is not very practical, for that you are much better off with a 34-inch ultrawide monitor with a resolution of 3440x1440 pixels, for example. One application for a monitor in this class that is also potentially attractive is gaming. We have stated this before: a big monitor contributes to an immersive experience, and with 40 inches you are almost literally 'in' the game world. 

Television alternative?

Furthermore, big monitors such as these can of course double as a TV screen: connect an external tuner and you are ready to go. So why not simply buy a television? These are often available at attractive prices in this format, also with ultra hd resolution. This is a good question and no decisive answer. It is possible that you find an excellent offer of a 40-inch television with excellent image quality and also a good amount of connectors for devices. 

However, televisions rarely have displayport-connectors, which is what you want to use if you have an older graphics card - or even the most modern Intel HD Graphics - as source of a uhd-signal. Aside from that the image quality of most cheap and small uhd-televisions is nothing to write home about: viewing angles, brightness and contrast are often average. Lastly most televisions have a scaler that is optimized for video: they have the necessary electronics to upgrade the image signal. You can discuss the usefulness of this feature, but the effect is that input lag is present, which means that there is a delay between receiving the signal and displaying the image; this is always clearly higher when compared with monitors. For games a high input lag (over 32 ms) is very undesirable, and most gamers tolerate no input lag whatsoever.
