Most often, the average user encounters the following causes and malfunctions:
Hardware “inconsistency” between the monitor and the computer’s video card;
Damaged cable;
An unsuitable driver, and not necessarily a display driver - most often a video card.
The main reasons why the computer monitor has a blurry image
To diagnose and resolve such problems, you must do the following:
1. Use a modern digital monitor connection
Almost any modern monitor, being connected in this way, can automatically configure itself to best parameters. This is usually done through a fairly simple and intuitive monitor menu - by selecting an item called “Auto Configuration”.
2. Configuring image output parameters.
Limit specific hardware capabilities. To begin with, set everything to default (brightness, color, temperature), and set the frequency to 60 Hz.
note! This must be done both on the device itself and in software video cards. It must be remembered that the monitor driver is not that important - it is usually responsible only for accurate color reproduction, but not for various fine settings, such as anti-aliasing or frequency.
3. Setting up and updating the video card driver
A common problem is when standard settings The video card does not have a resolution supported by the display. This can be solved by reinstalling or updating the video card drivers, or changing the resolution on the monitor, if this is possible from its menu.
Important: Modern video cards are very complex and functional devices. The number of settings items for them is in the hundreds. Ultimately, it may turn out that all the problems with the image arose due to one deeply hidden item, for example, “Stretched Scan” in the “Scaling Settings”.
To avoid such problems, it is better to use standard default values and not try to achieve the perfect picture through advanced options. This should be done only with a clear understanding of what a specific menu item is responsible for.
Quite often, when using LCD monitors on desktop computers, you can encounter a problem that the image on the monitor has become blurry. Why did this happen, because up to a certain point everything was normal? To answer this question, you need to understand what is causing this phenomenon, and only then take appropriate troubleshooting actions. Let's try to identify the most common causes.
Why does the image appear blurry?
Speaking specifically about the reasons for this phenomenon, almost all experts identify several of the most common ones, among which the main ones include the following:
- damage to the VGA cable or loose contacts on the connectors;
- incorrect settings of the monitor itself;
- inconsistency between monitor parameters and settings operating system;
- problems with drivers.
Note: sometimes an incorrect installation is included in the same list Windows updates, which can most often be found for some reason in the seventh modification. This is due to the fact that some updates (and this is confirmed even by specialists from Microsoft) are simply unfinished, and they contain updates to various VGA drivers, which lead to unwanted effects.
In this case, as soon as you notice the appearance of a blurry image on the monitor, the last installed updates must be removed manually, using at least the item viewing installed updates in the programs and components section, which is called up from the standard “Control Panel”.
A more effective way is to use specialized uninstaller programs like iObit Uninstaller. True, in both cases it will be necessary to re-set the search for updates manually and exclude from those found those that do not need to be reinstalled (as is already clear, updates are removed one by one with a reboot and check of the system). As more simple solution You can suggest the Show or Hide Updates utility, developed directly by Microsoft.
The simplest method for eliminating unwanted visual effects
But let’s assume that everything is in order with the updates or their installation is presumably disabled by the user himself. In most cases, it is believed that the appearance of a blurred image on the monitor can be caused by physical damage cable that connects the monitor to the stationary system unit. Try simply unplugging the plugs from the sockets and then connecting again. If this does not help, “ring” the cable or replace it with a new one. If possible, use an adapter to HDMI (the image will be stabilized immediately).
If everything is in order with the cable, try calling the built-in menu of the monitor and try to adjust the clarity of the picture by changing the device’s own parameters, after reading technical documentation.
How to get rid of a blurry image on the monitor in Windows 7 or another OS?
As for system settings, you can check them quite simply. On the empty space of the “Desktop”, right-click and select Screen Settings. In the settings, first of all, pay attention to the set resolution.
Almost all monitors are set to the system recommended value. If it is changed for some reason, install the one you need. Outdated monitors can work absolutely correctly in only one mode, but some support several possible modes. Also check your screen refresh rate settings. To start, set the indicator to 60 Hz. However, if the device supports the use of a higher frequency, it is better to use it (it is believed that the higher this indicator, the better the picture).
How to remove a blurry image on the monitor in Windows 10?
When you call the above-described setting item from the “Desktop” in the tenth version of the system, you will be redirected to the corresponding section located in the options menu.
If the zoom option is enabled with a value of 125%, and the panel and window size options have been changed, set the recommended parameters.
Note: if your computer or laptop has an integrated video card rather than a discrete one, you can adjust the necessary parameters to eliminate a blurry image on the monitor using, for example, the built-in “Intel Graphics and Media Control Panel.” If there are special control programs for discrete graphics adapters, it is recommended to change the settings not only in the operating system, but also directly in such applications (at the same time, by the way, you can test the chip together with the monitor).
Driver update issues
Finally, outdated video card drivers can also lead to a blurry image on the monitor. Update them using Windows completely inappropriate. To achieve optimal results, use the search for the latest management software updates like Driver Booster. In the case of discrete graphics adapters, it is better to use specialized applications from the chip manufacturer.
As a last resort, you can find the necessary drivers either on the manufacturer’s website, or search using special hardware identifiers VEN and DEV, which can be determined in the “Device Manager” (through the properties on the details tab), as shown in the image above.
Greetings!
When working with certain programs, you might find that some programs have a clear interface, while others have a vague (fuzzy, blurry, interpolated) interface. Particularly interesting is the fact that the same program with a “problematic interface display” can look completely normal on another computer. Why does this happen, what are the reasons? In this article we will try to answer these questions.
Why do elements become unclear in some programs?
The reasons for this phenomenon are related to the high resolution that the display of your computer or laptop has.
It’s one thing if, for example, the display has a resolution of 1920 by 1080 pixels and a diagonal of 27 inches, and quite another thing if a 15-inch display has the same resolution. In the latter case, all elements of the Windows interface and windows of programs and applications will be very miniature; the information in them will be difficult to perceive, causing excessive eye strain.
Developers at Microsoft who are developing the popular operating system Windows system, they understand this, but to this day they cannot completely solve this problem. A possibility was developed on their part. It is available in all modern versions of the operating system, and in Windows 10 it is even turned on automatically if, at the system installation stage, a display with a small size, but at the same time having a high resolution, is detected.
It is very easy to check whether scaling is enabled in the system. To do this, right-click on an area of the desktop free of shortcuts. In the menu that appears, select Screen Options.
The display parameters window will open, in the block Scale and markup Pay attention to the option that displays the current size of text, applications and other elements as a percentage. If it differs from 100%, then this means only one thing - the scale has been changed, and you will probably encounter incorrect display of the interface of some programs you use.
The root cause of the incorrect display of some programs lies in the reluctance of third-party developers to optimize their applications and implement recommendations developed by Microsoft that allow them to avoid problems with incorrect display when the system scale is increased.
Advice: always use latest versions programs and applications, because it is quite possible that in new version the developer has made the appropriate improvements, problem solving with a blurry interface.
How to fix the problem of a cloudy interface display in a specific program
Of course, you can switch the system scale back to 100%, but then absolutely all interface elements will be “smaller.”
You can do it differently and simply disable the modified scale for the specific application you are using. After switching, the interface elements of a particular program will become smaller, but the fuzziness of its interface will also disappear.
This is done like this:
