Most often, an ordinary user has 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 - most often a video card.
The main reasons due to which the image on the computer monitor is unclear
In order to diagnose and fix such problems, you must do the following.
1. Use a modern digital monitor connection
Almost any modern monitor, being connected in this way, can auto-tune itself to the best parameters. Usually this is done through a fairly simple and intuitive menu of the monitor - by selecting an item called "Auto-tuning".
2. Configuring image output parameters.
Limit specific hardware capabilities. First, 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 the video card software. It should be remembered that the monitor driver is far from that important - it is usually responsible only for accurate color reproduction, but not for various fine settings, such as anti-aliasing or frequency.
3. Configuring and updating the video card driver
The problem is often encountered when the standard settings of the video card do not have a resolution supported by the display. This is solved by reinstalling or updating the video card drivers, or changing the resolution on the monitor, if possible from its menu.
Important: modern video cards are very complex and functional devices. The number of setting points for them is in the hundreds. Ultimately, it may turn out that all the problems with the image arose from one deeply hidden item, for example, "Stretch Unfold" in "Zoom Settings".
To avoid such problems, it is better to use the standard defaults and not try to get the perfect picture through the advanced options. This should be done only with a clear understanding of what a particular menu item is responsible for.

How to fix a blurry, hazy, unclear image on the monitor?
ViewSonic VX2370Smh-LED monitor. Video card SAPPHIRE HD 5870 1GB GDDR5 PCIE (Game Edition) Today I reinstalled Windows (win7 x64 professional, license), after reinstalling it at first did not see my resolution, and when I saw it, the picture was smaller than the monitor size. I climbed into the monitor settings and turned on the "Screen fill" function, the picture spread, but the blur remained. If you reset the monitor settings to default, then the "Screen Fill" is simply turned off, the blur remains. - The video card drivers are the latest. - The monitor driver is installed (Standard Monitor Driver Signed Windows 7 x64 from the official site). - The resolution is native - 1920x1080. - 60Hz, tried other values, did not help. - Connected via HDMI.
I tried to turn off anti-aliasing for TrueType fonts, it does not help, and blurring not only on fonts.

Blurred image on the monitor
How many years I have been using a personal computer, now it is difficult to say for sure. But I always tried to use exactly LCD monitors. On them, the picture is better, and it takes up less space. But here, which is especially characteristic, everyone sometimes had the same problem, which will be discussed below. The difficulty is that it is a little difficult to describe in words, nevertheless, it is worth trying. How can I put it ..? Often the image on the monitor is "blurred" to the right or left. This problem is most noticeable in contrasting places. For example, when black text is printed on a white background, there is a gray “tail” or “train” from the text to the side. (click to enlarge) In order to better understand what is at stake, let's look at the image on the left, which I specially drew in Photoshop. Since it will not be noticeable on a regular screenshot, and a similar effect can be clearly seen only on a screen or a photograph. So, we see that the picture is “smeared” or simply repeats itself many times horizontally, as if moving. By the way, in English there is such a very pertinent concept here - monitor blur. On the Internet, a similar question has been raised more than once (this is easy to check thanks to Google), but no one has offered a good solution. Of course, the first thing to do is to enable automatic image correction on the screen itself, and then update the drivers for the video card. But the most effective way, which has repeatedly helped me out (let me be the captain for a bit with the obviousness), is to simply check the cable that goes from the system unit to the monitor. Often these bands and noise may not appear due to a problem, but because the signal is partially interrupted - just try to re-plug the VGA cable.
Quite often, when using LCD monitors on stationary computers, you can encounter a problem associated with the fact that the image on the monitor has become blurred. Why did this happen, because until a certain point everything was normal? To answer this question, you need to understand what is the cause of this phenomenon, and only then take appropriate troubleshooting actions. Let's try to identify the most common causes.
Why does a blurry image appear?
Speaking about the reasons for this phenomenon, almost all experts identify several of the most common, among which the main ones are:
- damage to the VGA cable or loose contacts on the connectors;
- incorrect settings of the monitor itself;
- inconsistency between monitor parameters and operating system settings;
- driver problems.
Note: sometimes incorrect installation of Windows updates is included in the same list, which most often can 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 incomplete, and they contain updates for all kinds of 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 for viewing installed updates in the programs and components section, which is called from the standard "Control Panel".
A more effective tool can be called the use of specialized uninstaller programs like iObit Uninstaller. True, in both cases, it will be necessary to re-search for updates in manual mode and exclude from those found those that do not need to be reinstalled (as already clear, updates are deleted one by one with a reboot and checking the system operation). As an easier solution, you can offer the Show or Hide Updates utility, developed directly by Microsoft.
The simplest method to eliminate unwanted visual effects
But, suppose that the updates are all right or their installation is presumably disabled by the user. In most cases, it is believed that the appearance of a blurred image on the monitor can be caused by physical damage to the cable that connects the monitor to the stationary system unit. Just try to remove the plugs from the connectors and then reconnect. If this does not help, "ring" the cable or replace it with a new one. If possible, use an adapter to HDMI (the image stabilizes immediately).
If everything is in order with the cable, try calling the built-in monitor menu and try to adjust the clarity of the picture by changing the device's own parameters, after reading the technical documentation.
How to get rid of blurry image on the monitor in Windows 7 or other OS?
As for the system settings, it is quite easy to check them. In an empty space of the "Desktop", make a RMB and select the item of the screen parameters. In the settings, first of all, pay attention to the set resolution.
Almost all monitors are set to the recommended system value. If it is changed for some reason, install the one you need. Outdated monitors absolutely correctly can work in only one mode, but some support several possible ones. Also check the refresh rate settings. First, set it 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 blurry image on the monitor in Windows 10?
When you call the above setting item from the "Desktop" in the tenth version of the system, you will be redirected to the corresponding section located in the parameters menu.
If the option to increase the scale with a value of 125% is enabled, as well as the options for the sizes of panels and windows are changed, set the recommended parameters.
Note: if there is not a discrete, but an integrated video card on the computer or laptop, to eliminate the blurry image on the monitor, you can adjust the necessary parameters 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 also test the chip together with the monitor).
Driver update issues
Finally, outdated drivers of the video card itself can lead to a blurry image on the monitor. Updating them using Windows is completely inappropriate. For optimal effect, 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 by 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.
