Laptop watching TV flickering screen problem?

The common causes of screen failures such as screen flickering and screen shaking are: first, the quality of the screen itself, screen aging or inferior products, second, the screen line contact will not be damaged or damaged, and third, the motherboard screen power supply is abnormal or the screen failure caused by the virtual soldering of the graphics card BGA packaging chip, it is recommended that you send it for repair and testing.

During the warranty period, send the customer service for maintenance, free of charge (except for man-made damage) After the warranty period, I can help you detect and determine the fault point for free in Beijing, and it can be repaired on the same day.

If you are not in Beijing, it is recommended that you find a reputable and skilled repairer to help you overhaul.

In fact, I don't recommend using any win7 system,Most people are chasing the trend,In fact, win7 system has a lot of drivers or application software is a certain configuration gap with the machine we usually use。 Sometimes it's better to use a system like YLMF or a basket or a tomato. This problem may be a driver problem of the graphics card,It is recommended that you do not use the driver that comes with win7,You can go to the Internet** the corresponding driver,Or install a driver wizard。

Of course, the cause of display aging or electromagnetic interference is not excluded. Good luck!

I think there should be a problem.,Didn't this happen to HP in the end?,How long has it been since I bought it? It's as if they're promising a replacement for hardware issues!

Summary. 1.It may be that the resolution and screen refresh rate are to be adjusted.

Right-click on the computer desktop - Properties - Settings - adjust the "screen resolution", and then click "Advanced" - "Monitor" - select the appropriate refresh rate in the "screen refresh rate", and the general hertz is OK.

2.If the refresh rate is still flickering, it means that your computer's graphics card does not support the 32-inch large monitor well, and you can consider adding a separate graphics card to solve the problem.

3.There may be a problem with the VGA interface of the LCD TV.

4.There is electromagnetic interference???

Why is the flickering screen so serious when the computer is connected to the TV?

This is the easiest.

I tried it, but it was stuck.

It could be that there is a problem with your laptop's jack, and it may be much better if you try to replace the next cable with a magnetic ring shield.

Will the jack flash if there is a problem.

Yes. Poor contact.

The quality of the line.

Hello, dear, very happy to answer for you! Here's the answer, check it out! There are two reasons for screen splashing:

Cable mismatch and incorrect setup of the monitor. Let's analyze them separately:1

Unplug and reconnect the current signal cable connected to the monitor, or try to see if there is any problem with the signal cable on another monitor. You can also directly replace a higher bandwidth signal cable such as a signal cable to increase the frequency of signal passing, reduce signal distortion, and prevent screen flickering when free-sync is enabled. Display 2

Refresh rate mismatch: If there is no problem with the cable of the external monitor, check the screen refresh rate of the monitor, and if the refresh rate of the main monitor is higher than that of the secondary screen, you need to adjust the refresh rate of the main monitor to be the same as that of the secondary screen. 3 The conflict between FreeSync and G-Sync is well known, Free-Sync is a function launched by AMD graphics cards to prevent screen tearing, G-Sync is a similar function launched by NVIDIA, if you are using an N card, and the G-Sync function is turned on in the control panel of the graphics card, and the FreeSync option in the OSD of the monitor is also turned on, it may be because the two syncs are incompatible and cause the screen to splash during the game, Then you can try to turn off free-sync.

If none of the above fails, it may be due to the effective scope of the free-sync itself. Whether the free sync function can be turned on correctly has an effective range,That is, the refresh rate variable range,Beyond this range can not be turned on,The general minimum value is 48,The highest value depends on the highest refresh rate that the display can support。 When turned on, the refresh rate will change frequently between high and low, because the low refresh rate and high refresh rate liquid crystal molecule opening rate are not the same, which will produce a difference in brightness, causing the picture to flicker.

This kind of splash screen itself has a low chance, and it is not a human solution. Your questions have been answered! I hope to be able to help you, if there is something wrong, you can continue to consult, bear with me!

1. Know whether the refresh rate is set correctly.

The way to check this is to right-click on Properties--Settings--Advanced --- monitor in the blank area ---of the computer's desktop, and you can see that the refresh rate of the monitor is set to "60", which is the reason why the display attendant screen is constantly shaking.

2. Check whether the graphics card driver is correct.

When you enter the refresh rate of your computer's monitor, you find that there is no refresh rate to choose from, which is caused by the incorrect or too old driver of the previous graphics card. You can check and install the latest version of the driver yourself.

Laptops require more computing resources and power for some graphics processing or gaming, and if the laptop's hardware or drivers do not provide sufficient computing resources or power failure, it may cause flickering or a brief black screen screen. This is usually caused by one of the following reasons:

Poor heat dissipation of the graphics card: If the laptop's graphics card is overheated, it can also cause issues with the screen flickering.

Graphics card hardware failure: If your laptop's graphics card hardware is damaged or malfunctioning, it can also cause issues with the screen flickering.

In order to solve this problem, you can try the following steps:

Clean your cooler: Clean your laptop's cooler regularly to make sure your graphics card doesn't overheat.

Check for hardware failures: If none of the above steps resolve the issue, you may need to contact your laptop manufacturer or a professional technician to check if the hardware is faulty.
