How To Fix Blinking Monitor

Working and relaxing on the computer is a strain on the eyes, so the picture quality of the display should evoke extremely positive emotions. If the monitor screen constantly or periodically blinks – do not put the problem on the back burner.

Flickering negatively affects vision and general well-being of a person, increases wear and tear on display components .

Why is the monitor blinking

The reasons for blinking are divided into software and hardware. In most cases, the problem can be resolved by changing the screen resolution or updating the drivers. If the malfunction is hardware, it is more difficult to figure out why the monitor is blinking. Details of the display, video card can fail. Less often, the snag lies in the RAM or power supply.

Reasons on the computer side

Flickering can be disturbing due to a malfunctioning graphics card or monitor driver. Vidyahi firewood can fly for four reasons:

1. Overheating or insufficient power supply, excessive overclocking of the video card.
2. Incorrect operation of the adapter after updating the drivers. This happens when new software is installed to order an outdated video.
3. Incompatibility of the driver with the work of some programs that actively use graphics, for example, with computer games. This mainly refers to the 3D filtering and anti-aliasing options. If the user has disabled anti-aliasing in the graphics control panel, then some game may not like it. Hence the conflict, incorrect operation of the drivers. As a result, the monitor flickers annoyingly.
4. A virus has settled on the hard disk, which prevents the normal work of the computer.

Not docking with the firewood of the monitor happens less often. Much more often the picture is spoiled by a weak screen frequency.

Hardware problems from the PC side :

• the port to which the video cable is connected is faulty;
• incorrect operation of the video adapter;
• RAM crashes;
• the power supply is naughty.

Reasons on the side of the monitor

The display has a lot less settings as it only receives and displays a ready signal. The only thing you can do to eliminate flickering without spending money is to use push-button or touch controls and return to the original monitor settings. This is usually helped by selecting the AUTO item.

In the event of a hardware problem, the culprit for the flickering could be:

• power supply (capacitors are often brought in);
• backlight lamp;
• display matrix and so on.

You can replace the external power supply yourself, in more severe cases it is worth contacting the service. The wizard will check the matrix, perform diagnostics with knowingly working lamps, establish the cause and announce the cost of the repair. If you need to change the lamp, it will take about 1000 UAH. The saddest option is a matrix breakdown: it often makes no sense to buy an expensive part for an old display.

The monitor flickers: what to do

It is better to understand, following from simple to complex. First of all, check the tightness of the cable connection. The next step is to search for software problems: we look at the frequency of the monitor, we check the drivers. Did not help? Then let’s move on to hardware issues. We determine the culprit of flickering: the reason may be a display, a system unit or a cable. Then we fix the malfunction on our own or take the iron for repair.

Adjusting the refresh rate

Finding out what to do if your monitor is flickering in Windows 10 . Algorithm for setting the refresh rate:

1. Right click on the desktop, go to “Screen Options”.
2. Open “Additional screen options”.
3. Scroll down to Graphics Adapter Properties.
4. We move to the “Monitor” tab.
5. In the menu “Screen refresh rate” we stop at a more suitable option.

Typically a higher frequency should be set to eliminate flicker (60-75 Hz for inexpensive monitors). Many people prefer to play at 144 Hz, if, of course, the hardware allows. Top frequencies in hertz, depending on the screen matrix:

To find out the best option for the display, you can look at the technical documentation or information on the manufacturer’s website. Be sure to disable any modes that are not suitable before changing the setting. To do this, there must be a check mark in the corresponding checkbox.

If you have outdated Windows 7, the algorithm will be approximately the same:

1. Right click on the desktop, select “Screen Resolution”.
2. Next – “Additional parameters” → “Monitor”.
3. Adjusting the refresh rate.

Updating monitor and video card drivers

If you do not have video card drivers in a separate folder on your computer , it is better to download them in advance. In the case of a stationary PC, for this we go to the website of the adapter or motherboard manufacturer. It is even easier for laptop owners : they can navigate by the laptop model.

Further procedure:

1. In the device manager, we get from the “Start” by typing the devmgmt.msc command there.
2. Double click on “Video adapters” to open the contents of the section. Right click on the installed video card and select “Delete”. In principle, you can not delete the drivers, but update them, but this is not the best option.

After uninstalling, install the downloaded drivers. To do this, run the batch file, accept the license agreement, select the quick installation option. During the installation process, the screen may blink, its resolution may change.

In case of problems with drivers, there are situations when the “Video adapters” section is missing in Device Manager. We do not get lost – we take into circulation the item “Unidentified devices”. A yellow exclamation mark is a good sign: it speaks of an easily fixable driver-related glitch.

Monitor drivers rarely fail. Often, standard software provides communication between the device and the OS.

Checking cables and connections

Among the hardware problems, the simplest ones are related to the cables. These include poor connections between signaling and receiving devices. Try pushing the video cable closer to the monitor and PC. If there are fixing screws on the cord, see if they are screwed in. If you have an adapter, you should also pay attention to checking it by replacing it with a known working one.

Cable breakages are less common, but they also happen. Evaluate the appearance of the cord for mechanical damage. Wiggle problem areas, unless, of course, this is a power cable designed for 220 V. Does the image stop blinking? Fine! Change the cord to a new one and enjoy a flawless picture of the screen.

A seemingly working cable can also be damaged, so the best option is to check the display with a knowingly working cord. If the monitor does not blink, what to do is clear: change the problem cable.

In a laptop, the screen receives a signal via a loopback. Visually assessing its condition will not work, but you can tilt the laptop lid and watch the flicker. If in some position the picture does not blink, most likely the loop is faulty.

What to do if the monitor blinks when turned on

It happens that the display jams when turned on, but over time the picture stabilizes. You can, of course, ignore the unpleasant symptom, but in this case, over time, the blinking period will increase, and you will have to wait for a normal picture not 5 minutes, but 10, then half an hour, an hour, etc. Also, do not discount the property of small faults, which eventually develop into large ones. If the monitor blinks when turned on for a period of time, the load on the backlight lamps increases during this period, as a result of which their resource will be reduced.

In most cases, the monitor blinks during system boot due to power problems. Treatment options:

• If the display has a remote power supply unit, replace it with a serviceable one. It is only important not to make a mistake when searching for a block. It should be rated for the same volts and amperes as the worn out one. You should also pay attention to the diameters of the plug.
• If the PSU lives inside the monitor, it will most likely need to replace the swollen capacitors.

In conclusion, a few words about the flashing of the display in gluttonous games. In this case, you need to look at the settings of a resource-intensive program, usually they are in the “Graphics” or “Video” section. Set them to a minimum, remove anti-aliasing and anisotropic filters. If the problem goes away, gradually increase the settings. This way you get the optimal balance between stability and realism of the picture.
