The host does not turn on the power supply of the single differential display, and it is all with a

Check the power supply and graphics card status, and adjust them in time.

Summary. The first trick: check whether the connection between the monitor and the graphics card is loose. Caused by poor contact"Clutter"、"Noise"Blurred screens are the most common phenomenon.

The second trick: check if the graphics card is overclocked. If the graphics card is overclocked, it will usually appear irregular and intermittent horizontal stripes. In this case, the overclocking amplitude should be reduced appropriately. Note that the first thing to do is to reduce the memory frequency.

The third trick: check the quality of the graphics card. If there is a problem with the blurred screen after replacing the graphics card, and it is in use.

After the first and second tricks fail to work, you should check whether the quality of the graphics card's anti-electromagnetic interference and electromagnetic shielding is passable. The specific method is: keep some parts that may cause electromagnetic interference away from the graphics card installation (such as hard disks) as far as possible, and then see if the blurred screen disappears. If.

Trick 4: Check if the resolution or refresh rate of the monitor is set too high. The resolution of the LCD display is generally lower than that of the CRT display, and if it exceeds the best resolution recommended by the manufacturer, there is a possibility that the screen will be blurred.

The host unit does not turn on the display screen.

Dear, hello, please wait, we have seen your question, and we are quickly sorting out the information for you, and we will send your answer to the little master immediately. Thank you for your support, recognize my service, and remember to give a thumbs up<>

Check the quality of your graphics card. If there is a problem with the blurred screen after replacing the graphics card, and it is in use.

After the first and second tricks fail to work, you should check whether the quality of the graphics card's anti-electromagnetic interference and electromagnetic shielding is passable.

If. Trick 4: Check if the resolution or refresh rate of the monitor is set too high.

The resolution of the LCD display is generally lower than that of the CRT display, and if it exceeds the best resolution recommended by the manufacturer, there is a possibility that the screen will be blurred.

First, make sure that the monitor's connector matches the console's interface. If you're sure you're connecting correctly, but you're still getting a blur, it could be one of the following.

1.The signal cable of the display is loose.

Check that the signal cable connecting the monitor to the main unit is securely connected. Sometimes, the connecting cable may become loose due to prolonged use, relocation, or careless pulling. If this is the case, reinsert the signal cable of which lead is between the monitor and the host into the interface between the host and the monitor.

2.The distance between the monitor and the host unit is too far.

Too far between the monitor and the host computer may cause interference in signal transmission. Try connecting the console close to the monitor or using a longer monitor signal cable.

3.The monitor or graphics card is the envy of the sail barrier.

Check to see if the monitor itself or the graphics card is faulty. You can connect your display to another computer or connect another display to your current computer to see if you still have a blurred screen.

4.The graphics card slot is faulty.

If the monitor is using a discrete graphics card, it may be caused by a damaged graphics card slot, try replacing the slot.

5.Problems with the monitor driver.

The old drivers should be uninstalled before installing the new graphics drivers. Otherwise, different versions of the driver may cause conflicts, resulting in a blurred screen. You can try to use a driver one-click equipment tool such as the driver wizard to automatically update the drivers.

Before you can fix the problem, you need to determine the cause of the problem. Once we have found the root cause of the problem, we can take steps to address it. If you can't solve the problem of blurred screen, it is recommended to consult a professional.

The phenomenon of "blurred screen" is manifested through the display, and the cause of the blurred screen is usually not the display. There are two main causes of the original excavation:

1.If the graphics card is loose, unplugging the graphics card and reinstalling it after shutting down the card can usually solve the problem.

2.The system is overheating, including high CPU temperatures and graphics card chip temperatures (Note: dust inside the cooling fan and heatsink). Cooling fans can be installed in the appropriate locations of the chassis, or the chassis can be placed in a well-ventilated area.

The main reasons for liquid crystal display (LCD) splash screen are:

1. Poor graphics card characteristics;

2. The synchronization circuit of the LCD is old and faulty, and the screen is blurred in use, which may be a partial failure of the hardware, and the general dispersion is the poor contact of the display screen;

3. The basic working conditions of the microprocessor are abnormal, the +5V power supply is unstable, and the reset electrical hail circuit components and crystal oscillator performance are poor;

4. The microprocessor itself is damaged, or the memory data is lost;

5. The scaler circuit and the LCD screen itself are faulty.

Summary. The cause of the blurred screen is troubled from the following aspects: graphics card driver, power supply, cable, display, and graphics card faults.

In terms of graphics card driver, you can change a graphics card driver, or use the driver wizard to reinstall the graphics card driver.

What is the power of the power supply? If the power supply is used for a long time, the peak value will drop, and the unstable power supply will also cause the failure of the blurred screen.

Cables and monitors are excluded by changing to other monitors and cables.

If all of the above are normal, most of the graphics card hardware is faulty, and you need to contact after-sales inspection and maintenance.

The display is used directly with the screen, and it has nothing to do with the host, because the same is true for turning on the display without the host.

The cause of the blurred screen is troubled from the following aspects: graphics card driver, power supply, cable, display, graphics card failure, graphics card driver can replace a graphics card driver, or use the driver wizard to reinstall the graphics card to drive the power supply, how big is the power supply? If the power supply is used for a long time, the peak will drop, and the unstable power supply will also cause the fault of the flower screen, and the wire and display are replaced with other displays and cables to eliminate the abnormality, if the above are normal, most of them are graphics card hardware failures, and they need to contact after-sales inspection and maintenance.

The drive is no problem, the cable is no problem, and the power supply of the display is waiting for me to send a picture.

Can you reply. Let's get it repaired.

Big problems are likely.

You try a different monitor.

Other monitors are no problem connecting to the host computer.

Something is wrong with your monitor.

I'm going to fix it.
