The question of the appropriateness of using televisions as monitors arises against the background of a steady tendency to reduce the cost of the former and to improve image quality and diagonal size. Let’s try to find an answer to it.
I must say that in addition to its main purpose. broadcasting television programs, the use of modern TVs as multimedia players (a screen in a home theater), as well as devices that display images from game consoles, is practiced. And models that support SmartTV can generally be an alternative to a computer. And all this is good, is the TV capable of providing full-fledged work with text files, graphic images or editing?
The bulk of TV models does not imply a prolonged presence of a person in front of their screen. The picture, which is extremely bright, contrasted and saturated, has a tiring effect on the eyes. And the presence of various improvers, the purpose of which is to give the image maximum realism when viewed from a considerable distance, leads to a deterioration in the clarity of the text on the display. In addition, the presence of embellished color reproduction, and in addition, the narrowness of the coverage of sRGB color spaces, not to mention AdobeRGB, does not allow and photo editors to work correctly.
Of course, the whole aspect of the capabilities of TVs opens if you watch movies on the Internet or actively gaming. This statement is especially true for televisions with a large screen diagonal, which significantly increases the realism of everything that happens on the screen. Below are the weaknesses and strengths of TVs, if used as monitors for a computer.
1. Unconditional trump cards of TVs include their cost, taking into account the size of the diagonal of the screen. The purchase of a TV will allow you to save significantly, because its cost is significantly lower than that of monitors with similar sizes.
2. Televisions have special operating modes that allow, for example, in dynamic mode to illuminate dark scenes when watching movies or during the game. Actually this technology was first used on TVs, and only much later it began to be used on monitors.
3. A large screen allows you to comfortably work with small details, which is important when editing a. Manygraphers have to use two monitors for this, which are installed tightly against each other. And of course, it’s much easier when you can do the same thing on one TV with a large diagonal.
4. An important advantage of a large television screen is the presence of the effect of immersing deep into what is happening, regardless of whether a very interesting film is being watched, or an action scene appears in a computer game.
1. Televisions with IPS-matrix have a high level of contrast, and this inevitably leads to the fact that there is a loss of detail in black shades. This is especially striking if the screen is located at a great distance.
2. For embellished pictures on TVs, saturation is excessively lifted, and this has a negative impact on the ability to perceive colors and does not allow to work in photo editors in the correct mode.
3. The TV does not provide such clarity as on the monitor if you are surfing the Internet, or you are working with texts. As a rule, the system designed to process images with the aim of embellishing is to blame. On some models it is possible to solve this problem, for which the anti-aliasing is disabled.
4. If a model with a large screen is installed at close range, then on the screen you can see the individual pixels that are components of any image. For this reason, for TVs whose diagonal exceeds 32 ″, it is recommended not to allow the use of a screen resolution lower than FullHD (1920×1080).
5. If I work for a long time, I use the TV screen, my eyes get very tired. What contributes to a considerable degree to the need for a constant translation of the gaze left-right on the surface of the large screen, and even more tiring is the movement of the eyes down and up.
6. A large number of TVs have an image delay (Input Lag). Incut lag (should not be confused with the time necessary for the matrix response). this is the length of time it takes for the TV to display the signal sent to it. Simply put, during each completed action, there will be a delay by the value of Input Lag, which can last from 30 ms to 150. While watching a TV show or movie, this function is practically not noticeable. The bulk of modern TVs has special modes, the use of which can significantly reduce the size of the output delay. In addition, today there are models, such as, for example, Sony KDL-32WD603, in which it was possible to reduce this effect to a minimum level, due to which there is almost no influence on the perception of the picture.
How can I connect a TV to a computer
Connecting a TV to a computer can be done using one of the three main interfaces: VGA (D-Sub), DVI and HDMI. And if using the latter you can broadcast in FullHD-quality, then the use of the first two is recommended only when other pairing scenarios fail.
1. Connection using the VGA connector. The main interface that allows you to connect the monitor to a computer is considered an analog VGA port. And therefore, if a decision is made to use the TV as a device with which information will be output, it is quite possible to use this connector. However, it must be remembered that you should not wait for the maximum resolution of the transmitted picture at the FullHD level, so it will be equal to 1600×1200 pixels. In addition, you will have to additionally use a cable with “tulips” (RGA) or “minijack” (3.5 Jack) to transmit sound.
2. Connection via DVI. The bulk of computer graphics cards have a DVI port. an upgraded version of the VGA interface. It can be in three forms:
3. HDMI connection. This port is considered the best when the TV is connected to a computer. With its help, it is possible to transmit with a high level of resolution (reaches 3840×2160 pixels) and multi-channel sound using a single cable. Often, the interfaces of TVs have from two to three HDMI-connectors, so that it is possible to simultaneously connect multiple devices. Today, the disadvantages of HDMI-connection include a limited cable length (not more than 10 m) and a fairly high price.
The disadvantage of connecting using DVI and VGA cables is that the connection of the connectors is screw. This means that in the case when someone accidentally hits these cables with his foot, damage to both the TV and the card of the computer occurs.
When planning to purchase a TV, to use it as a monitor, you need to clearly understand what scenarios it will be intended in the first place. So if you plan to work actively with office applications and browsing on the Internet, then you can limit yourself to a 32-inch TV. But for gaming or watchings with maximum immersion, you should choose models whose diagonal is in the range from 36 ″ to 50.
