It's better not to use LCD TV screen instead of computer screen. Due to different application fields, the screen, size, brightness, contrast, gamut, color temperature, response time, interface and so on are different. In their respective fields, it can be said that they can not perfectly replace each other.

due to different application fields.
the screen, size, brightness, contrast, gamut, color temperature, response time, etc Interfaces are different.

Can LCD TV replace computer screen? What are the advantages and disadvantages? What is the effect?

in their respective fields.
it can not be perfectly substituted for each other.

pros and Cons:
the advantage of LCD TV is that it is cheaper than the computer screen.
in addition, the advantages of LCD TV are contrast and brightness.
this is also why LCD TV is used to watch TV However, the brightness of LCD TV is higher.
so long-term use of TV screen instead of computer screen will cause certain damage to eyes.
take 46 inch TV as an example.
the suitable viewing distance is about 3 meters.
the viewing distance of desktop display is about an arm
therefore, if the LCD TV screen is used as a computer monitor, it will be very close to the human body.
this will cause damage to the eyes.





extended data
the difference between LCD TV screen and computer monitor:
1 Another obvious difference between LCD TV and LCD is the size.
the mainstream LCD TV is 32 inches, which is the smallest.
after 37 inches, 40 inches, 42 inches, it is more than 50 inches.
for LCD TV, the mainstream size is less than 24 inches, even 17 inches At present, the 19 inch LCD still has a large shipping volume.

is the largest LCD in the market.
is the largest LCD in the marketHowever, the 30 inch Samsung 305t and Dell 3008wfp are still two inches away from the 32 inch entry-level LCD TV.

the main reason for this difference is the different ways of using them.
the TV is used to watch dynamic images.
when it is placed on the TV cabinet, the suitable viewing distance should be at least 3 meters, This distance can also be continuously increased.
for example,
the appropriate viewing distance for a 50 inch TV is more than 5 meters.
therefore,
the TV is not afraid of being too big, as long as the viewing distance is extended.


such a short viewing distance directly results in that the larger the display is, the better, a 30 inch screen, It is the limit size of the current display.
the distance between the human eye and the display will not exceed 1 meter, and the common distance should be between 50cm and 80cm.

2. The difference between resolution and point distance

the resolution of LCD TV.
at present, the mainstream is 1366 * 768 and 1920 * 1080, even 55 inch TV, The resolution of LCD is much higher than that of LCD.
the 21.5-inch wide screen has 1920 * 1080 resolution, and the mainstream 22 inch resolution is 1680 * 1050.
you can see the resolution of the same size screen, LCD is much higher than LCD TV.

take 30 inch LCD and 32 inch LCD TV with similar screen size as an example.
the resolution of 30 inch LCD is 2560 * 1600254; The mainstream 32 inch LCD TV is 1366 * 768, and the point distance is 0.5185mm.
the size difference is only 2 inches.
the difference between the horizontal / vertical resolution and the point distance is about double.

for example, 30 inch Dell   3008wfp.
2560 * 1600 resolution, 32 inch LCD TV, the mainstream is 1366 * 768 resolution.

this means that if the above two products are connected to the PC at the same time, the single screen display content of the display can reach four times of that of the TV, and the display font is smaller, and the image display is more delicate.

3 The difference between the two interfaces and nearly ten interfaces is clear.
in fact, the problem of this interface is also clear at a glance. I will briefly write about it.
generally, mainstream LCD displays have two interfaces: DVI + VGA.
some high-end displays will have HDMI interface.
this is a high configuration for the display.

the signal interface of the display.
simple, Two.
but the TV has at least ten interfaces.
TV terminals are essential, including HDMI, AV, component, s, D-sub and headphone interfaces.

4. The difference between TN panel and wide view panel
at present, TN panel is widely used in mainstream LCD, The biggest drawback of this kind of panel is that the viewing angle is small.
if the user is not facing the display, it is easy to appear color deviation; If the deflection angle is slightly larger, the color of the image will be greatly distorted, making it invisible.
when the deflection angle is slightly larger, the color of the image will be distorted

The 32 inch mainstream LCD TVs all use wide viewing angle panel.
that is, VA or IPS panel. Compared with TN panel, the biggest advantage of wide viewing angle panel is that it has a wide viewing angle and can be used normally in a large angle range.

5 The difference between brightness below 300cd / m2 and brightness below 400cd / m2
the brightness of mainstream LCD is mostly nominal 300cd / m2 or 250cd / m2.
the measured brightness is mostly between 200cd / m2 and 300cd / m2, and the mainstream LCD can adjust the brightness of the LCD, The brightness can be adjusted to less than 100cd / m2.


the brightness of mainstream LCD TV is 400cd / m2.
many LCD TV can reach the brightness above 500CD / m2.
an ordinary TV has the brightness of 450cd / m2.
if the brightness is used as a desktop display, it will do great harm to people's eyes.


6 The difference between accurate color restoration and rich color restoration

if you try to connect the computer host to the LCD TV,
you will find that the displayed picture will be very gorgeous, with absolute serious color deviation. The biggest reason for this problem lies in the gamma adjustment.


the default standard gamma value of PC display is 2.2.
although it is difficult for consumer display to achieve complete accuracy, However, the mainstream products in the market will not be too different.
the PC host is also set for the signal output to adapt to the gamma value of 2.2.
this two-phase matching.
we can see the accurate (or nearly accurate) color performance of the display.


LCD TV is affected by the standard system.
in this way, we can see the accurate (or nearly accurate) color performance of the displayAccording to the evaluation results,
the gamma value of LCD TV is about 2.4.

in this way,
when the PC set by 2.2 gamma value is connected to the TV LCD with 2.4 gamma value, the compatibility will be affected, and the color will become very rich. What we see is the completely wrong color.
in this way, the PC set by 2.2 gamma value will be connected to the TV LCD with 2.4 gamma value   Now.
in order to adapt to different input devices, some high price liquid crystal displays have built-in gamma adjustment options. By adjusting this option, they can better adapt to the signal input of DVD player and TV set-top box.

but the display effect is still not comparable with that of TV liquid crystal.
LCD TV rarely has built-in gamma adjustment.
so far as it is concerned, If the TV is forced to be used as a monitor on the host computer, the serious inaccuracy of color will be a big problem.

reference materials source: People's Network - eight differences why LCD TV and monitor are not common 1. LCD TV can be used as a computer's display screen.
but it is rare to replace it, theoretically it can.

2 The advantage is that the screen size of the TV is larger.
the display effect will be better than that of the monitor.
the disadvantage is that the screen size of the TV is larger.
so the distance between pixels is larger, and it needs a long distance to see clearly, so it is very inconvenient for some computer operations, such as editing documents or image processing; However, the monitor can fully meet this demand.

3. In daily use.
it is recommended that the computer should be connected to the monitor as the display screen, which has better actual use effect and better operation experience.
the TV can be used as the auxiliary display screen of the computer.
the TV can be used as the auxiliary display screen of the computerFor example, when playing high-definition movies or games on the computer, you can get a better viewing experience by using the TV as the display screen.

LCD TV can not replace the computer display screen.
the disadvantages are as follows:
1. First of all, their brightness is different.
TV needs long-distance viewing.
therefore, the brightness of TV is more than twice that of the display screen, The gray scale of LCD TV is much lower than that of monitor.


3. Ordinary 8-bit LCD can display 256 gray scale.
16.8 million colors.
but when the TV is connected to the host computer.
only 16 ~ 236 parts of 256 gray scale can be displayed, The reason is that the gray-scale output standard of the computer does not match the gray-scale range of the TV.
the gray-scale loss means that the color is lost and the picture is darkened.


4. The use experience of the two systems is completely different.
playing games on the TV will delay and need to be adjusted, and the delay problem will also cause the picture to drag.
so for the sake of both eyes.
for the sake of mood, You'd better buy a monitor honestly.


summary:

LCD TV can't completely replace the normal monitor.
this is not only because the display effect is not ideal, but more importantly, it will damage the eyes.
however, it has little effect on long-distance viewing.
for example, it only uses the TV screen to play the movies and videos in the computer host,
