When the device is turned off, is it better to turn off the LCD screen or turn it on?

You don't need to turn it off, just turn the power off!

LCD TVs are often turned off well.

1. LCD TV standby consumes electric energy, and it is good to turn off from the perspective of power saving. To turn off the power, be sure to turn off the TV first, and then turn off the 220V mains.

2. Turning off the LCD TV when not watching can also protect the power supply circuit of the TV and other TV circuits of the TV department, so that the aging is slower. In a sense, it increases the life of the TV.

3. Turning off the LCD TV when it is not watching can also protect the TV from lightning strikes.

Problem description: Yes: During working hours, I often leave the computer to do other things, but I don't want to turn on and off the computer frequently, in this case, I want to protect the LCD display well, I want to ask:

1. In the case of leaving the computer many times in the morning, is it better to turn off the LCD display every time you leave to protect the LCD (because this shortens the working time of the LCD monitor)? Or do you not turn off the LCD monitor, and let the system automatically screensaver protect the LCD monitor?

2. Further question: Does frequent switching of the LCD monitor have any impact on the lamp tube of the LCD display and the life of the whole machine?

Thank you! Analysis:

It's good to turn it off, when the LCD monitor is working, it is by the back light to transmit the LCD screen to our eyes, so that even if you set up a screensaver, but the light is still working, in layman's terms, it makes no sense to set a screensaver on the LCD screen, because the screensaver is the same as when working (this is different from a desktop monitor, so don't use the desktop way for LCD).

In fact, there is no way,In the desktop properties,There is a piece in the screensaver item"How many times to turn off the display"This setting,When you wait for how many minutes to turn off the keyboard and mouse,The host automatically closes and transmits the signal to the display,So that the LCD will temporarily stop working,To achieve the role of protection。

I'm a slow typing and hope it can help you.

Turning off the power will have no effect on the TV. And you can save power without leaving it on standby all the time, killing two birds with one stone.

In the summer, when there is often thunder, the power is turned off and the power supply is going to be unplugged!

Winter doesn't matter!

1. The computer is a high-tech cutting-edge product, durable, and long-term boot is normal use (such as the computer room server). However, frequent power on and off can detract from the life of the computer, and it is the hard disk and monitor that suffer the most. The more appropriate approach is:

Do not use the computer within 20 minutes, do not need to move anything, 20 minutes - 1 hour can be used to sleep, standby, more than 1 hour to turn off the computer, this is not only to save electricity, but also conducive to the maintenance of the computer.

2. The boot sequence is generally to turn on the monitor and other peripheral facilities first, then turn on the host, and turn off the opposite, which is done to protect the host motherboard from the impact of the instantaneous current when switching on and off. The new generation of products has protection measures in this regard, but it is better to turn on and off according to the normal requirements.

3. It is best to dial the power supply after shutting down, and the power consumption is about 5W without dialing the power supply, and there are potential safety hazards, for safety and saving power resources, it is better to dial the power supply after shutting down (using a power socket with a switch).

After turning off the main unit, try to turn off external devices such as audio monitors. Turn on the peripherals before turning them on. It's better that way. The display switch will not be so fragile. In addition, today's monitors generally automatically power off.

After the computer is shut down, it is not necessary to turn off the monitor, but it is good to close it, although it is true that it is easy to be damaged by pressing multiple switches, but after all, the number of times you press this button is much less than the number of times you press the keyboard, and the keyboard can not worry, why worry about the monitor buttons? As long as you don't desperately want it to break, it's on the line, so it's mainly easier to break when it's turned on for a long time, because when the monitor is on, it's working, not to mention wasting electricity, and people can't stand it if they don't rest all the time, so it's recommended to turn it off.

Just pull the plug directly after turning off the computer.

Shut down? It won't be bad to adopt it, friend.

If the computer is turned off and the monitor is not turned off, there is no big harm. But it will cause many hidden dangers.

1.The monitor is powered on all the time, there will be a small amount of current, and turning off the monitor can save electricity;

2.In fact, the machine also needs to "rest", which can prolong the service life and keep the machine in a state of standby.

3.Lightning hazards. In the event of a thunderstorm, if you are unlucky enough to hit the AC wire you are using, the monitor will be destroyed.

Of course, if you develop such a habit, you can also do it: the switch of the monitor is kept on, the computer is turned off thickly, and the total power supply can be cut off.

Why can't you turn off the main monitor, which is equivalent to standby, that is, only the red light of the screen consumes a little power, but if the wires in your home are too old, it may be dangerous, it is best to buy a special socket for the host and the display, so that the power supply can be stable, and you can turn off the main switch of the socket when sleeping, so that it is much safer.

Today's displays support energy-saving mode, and when the host is turned off, the display will automatically enter energy-saving mode if the input signal is not detected for a few seconds.

A monitor that goes into energy saving mode consumes only a very small amount of energy to be ready to work at any time when it is turned on again. Therefore, there is no problem with not turning off the display, but from the perspective of energy conservation and environmental protection, regardless of the display for a long time, there will still be a certain amount of computer consumption, and it is wasted if it is not energy-saving.

It doesn't hurt, but it's better to turn it off. Otherwise, the monitor is always on standby! Waste of electricity.
