After the laptop and TV VBA are connected, the TV screen is blue, and the PC is normal. It s still t

The multi-display mode of the notebook has copy and expansion, replication is the same as the two screens, and the expansion of the secondary screen is the desktop color, and the mouse can be moved to the secondary screen to try.

The TV screen is also blue when there is no signal, and it is impossible to tell what kind of blue your blue is, and be careful to switch the TV to the VGA input.

According to what you said,VGA cable is no problem,There is no problem with the TV,The fault should be one of the three colors of the VGA port of the notebook,1、Connect the VGA cable firmly,2、Look carefully at the port of the notebook,3、If you can't troubleshoot the fault,Consider that there is a problem with the notebook graphics card,It is difficult to repair it.

Judging by what you said, laptops and TVs, as well as VGA cables, are normal. It's likely that you won't be able to manipulate it.

Under the premise that everything is normal in the notebook, if you want to use the notebook to connect to the external LCD or other display devices, you must first connect it correctly, and then you must operate the shortcut keys on the notebook before you can realize your wishes. Now take my notebook as an example, that is, the fn key (commonly known as the extended function key or the second function key) + f8 (there are also between f2-f8, there is usually a key identified by the display) can realize your wishes.

Another thing you have to pay attention to is that after pressing the above two keys at the same time, sometimes there will be a little delay, and it can be displayed in about 2-3 seconds, because different brands of laptops have different extension times.

In the case of my notebook, pressing the shortcut key combination at the same time will appear in order 1The laptop screen does not light up, only the external screen shows 2The notebook screen and the external screen are displayed at the same time, and the external screen is displayed separately on the notebook screen if there is no signal.

Different notebooks can be different from what I said, so just for your reference!

There are 3 possible aspects that can be solved by yourself:

1.Graphics card memory issues.

Replug it in, clean the gold finger, and see if the fan is normal.

2.Cable problem (replugging, checking VGA or DVI interface) 3Display issues (Check if the electrical outlet is powered on.) If it's convenient, connect it to other computers to see if it's normal).

It's not possible to restore with one click. If you don't have a system disc ready, the optical drive can be used. Start the computer and press the DEL key, set it to a disc boot in the BIOS, insert the system disk and reboot, basically complete it automatically according to the steps.

No, if you check that the system is free of viruses. It can only be a matter of heat dissipation. After using it for a long time, you can open the case to carefully sweep the dust inside, and add a little high-grade oil to the fan. The main problem is to reduce the temperature inside the chassis.

Generally, the graphics card failure will cause the image ripple interference, it is recommended that you replace the graphics card or other computers and try again to see if there is still the same ripple, to determine whether it is a display failure or a graphics card failure.

There are vertical stripes on the LCD screen, indicating that there is a problem with the source driver IC, or that its power supply circuit and cable are faulty;

This kind of fault is best sent to a qualified LCD professional maintenance department for maintenance, and it is about 120 yuan for repair.

I didn't see it.

Is the screen not working, out of the bright line, right?

Heat dissipation issues.

Take a fan and blow it.

The most common cause is that there is a problem with the data cable connecting your monitor to your computer's graphics card.

You try it differently.

It's the data transmission cable behind your monitor that is connected to the computer.,You adjust the position of the line with your hands.,Press it into the monitor.,If it's not good, I think you should go and change the line.,A line is about 50 oceans.。

There is a problem with the connection cable of the monitor (that is, the cable connecting the monitor to the host), the solution:

1. Check whether the contact part of the connecting wire behind the monitor is loose, if there is any loose place, please install it firmly;

2. Check whether there is a broken needle at one end of the connection cable between the monitor and the host, or loose, if there is a loose place, please install it firmly;

3. If the above two cases are not, then the display needs to be demagnetized.

There are generally several reasons why a computer screen turns blue:

1: Poor contact with the display line. Re-insert it, but don't try to change it.

2: The monitor driver block is damaged. Try to change the monitor, and take the monitor to repair it.

3,: The graphics card of the computer is damaged. Try it out with a discrete graphics card.

4: The primary color of the display 3 is too blue or the display is flushed, reset or degauss the display.

You try to change the line first, about 10 yuan.

No, you try to adjust the color adjustment on the display, generally there will be a few buttons under the display, you try.

If you are an old-fashioned computer with a large display, not an LCD, it may be due to the aging of too long, generally you pat the display next to the display with your hand, maybe it will be better, I have also encountered it, if it doesn't work, take it to repair, 50-100 yuan.

If you can't try to change the cable, it's your monitor that has a problem, go fix it!

Haha, the 5200 uses an STN screen, which itself is a garbage screen.

It's normal for the color of the screen to be blue, after all, it's an STN screen, and the contrast has not been adjusted well recently.

You can try to swap it again.

Graphics card Since it's a laptop, switch to another graphics card and see how the screen goes.

If both graphics cards are like this, it's a motherboard or screen problem, if you switch a graphics card, then update the driver of this graphics card, change a few more, choose a stable version, as much as possible, under the official website of the graphics card, Nvidia or AMD If it's still a blue screen for 2 or 3 drivers.

If the drivers have been changed, you can check for problems with your graphics card.

Inferior screen, find someone to repair the original screen. This kind of inferior screen is cheap to death, mostly between 80 and 180, and the repairer will charge you at least 300 500.

Try an external monitor on your laptop to see if the display is normal! If it is normal, it means that the display cable or the display itself is faulty! If that's the case, your graphics card is faulty! But most of the time it's a problem with the screen.

Brother, look like this, it's likely that IE has set the background color, or maybe the software has set the protective color, because your desktop looks normal, please refer to.

It is best to have a discrete graphics card and an HDMI port connected to an LCD TV with high-quality picture and sound.

Right-click on the desktop to set the TV to be displayed on a single screen.

Tuck in on the sound of the TV: control panel, large icons, sound, hardware by default.

Laptop screens can be blue for a number of reasons

1. Graphics card setting problems;

2. The screen line is broken or the contact is poor.

Solution: 1. Readjust the color in the graphics card settings, and readjust the color as follows (take Win7 N card as an example);

Click on "Hardware & Sound";

Click "NVIDIA Control Panel" to open the NVIDIA Control Panel;

Click "Adjust Desktop Color Settings" in the left menu bar;

Click "Use NVIDIA Settings" on the right;

Click the "Apply" button to save and make the settings take effect.

When the setup is complete, close the NVIDIA Control Panel and Control Panel.

2. If the above adjustments do not achieve satisfactory results, it should be that the screen line is broken or the screen cable interface is in poor contact, and it is recommended to send it for repair.

The settings of the screen are turned on, and the display is just a few buttons, you turn it on, find the option to restore the factory value, and make sure that it should be able to be restored.

Also, if you can't recover like this, the screen may be broken.

The screen slot on the motherboard is not in good contact and should be disassembled for inspection.
