The image on the computer is unclear. Fuzzy (cloudy, blurry) program window - how to fix it
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.
The developers at Microsoft who develop the popular Windows operating system 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 layout 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 the latest versions of programs and applications, because it is quite possible that in the new version the developer has made appropriate improvements that solve the problem 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:
Initially, the HDMI interface was developed on the basis of DVI, but, unlike the latter, it had support for audio signals and was tailored for household appliances - mainly televisions. Later, HDMI ports began to be added to monitors, and this is where confusion arose: the television signal is output in a limited color range, and televisions are calibrated so that the picture looks natural in this range. Monitors are designed for the full dynamic range, and accordingly, they display the correct colors only when the image is displayed in it.
First, let's figure out how the signal is output in general. In the vast majority of cases, the RGB model is used, that is, the picture is divided into three color components - red, green and blue. The intensity of each component is specified as an 8-bit number for each pixel, that is, it can vary from 0 (complete absence of a given color) to 255 (correspondingly, the maximum of a given color). In total, we get the opportunity to display 256 x 256 x 256 = 16777216 combinations (color gradations) - this range of colors is called Full RGB, that is, the full dynamic range. However, due to the limitations of the analog signal in household appliances, I had to resort to a trick and use not Full RGB, but Limited RGB (limited dynamic range) - values only in the range from 16 to 235 are used, that is, black is 16,16,16, white - 235, 235, 235. And in total we get 219 x 219 x 219 = 10503459 colors, that is, one and a half times less.
What exactly is the problem? It lies in the fact that a video card with an HDMI connection cannot determine what is connected to it - a monitor or a TV, and therefore, in the case of Nvidia video cards, the signal is output by default in a limited range, in the case of AMD - in the full range. There are no problems with video cards from AMD - the monitor works with Full RGB, the video card also produces a signal in Full RGB:
But Nvidia video cards by default consider all devices connected via HDMI to be TVs and produce a signal in Limited RGB when the monitor expects Full RGB:
As a result, the dynamic range of the image is narrowed, colors become faded, black looks dark gray (because the monitor thinks that 16, 16, 16 is dark gray), white also lacks intensity (because 235, 235 , 235 is no longer white), the same with other colors. That is, the picture suffers quite a lot, and this is especially noticeable with IPS monitors. However, it’s not difficult to fix this: you need to go to the Control Panel, find the Nvidia Control Panel there, go to the “Change resolution” column and set “Full output dynamic range”, and then apply the changes:
Also, if you wish, you can go to the “Adjusting color parameters for video” column and do the same thing there (however, if after this the films begin to look unnatural, it is better to return everything as it was, because some films are cropped to Limited RGB):
That's it, now the image on the monitor should become more saturated.
Of course, all this makes sense only if your monitor is connected via HDMI. If the connection is via DVI or DisplayPort, the video card “understands that a monitor is connected and immediately displays the image in Full RGB.
Computers and peripheralsBlurry images on a computer monitor can be caused by various reasons.
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, when connected in this way, can automatically configure itself to the 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 the video card software. 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 the standard settings of the video card do 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.

How to fix a blurry, cloudy, unclear image on the monitor?
Monitor ViewSonic VX2370Smh-LED. Video card SAPPHIRE HD 5870 1GB GDDR5 PCIE (Game Edition) Today I reinstalled Windows (win7 x64 professional, license), after reinstallation it did not see my resolution at first, and when it saw it, the picture was smaller than the size of the monitor. I went into the monitor settings and turned on the “Screen Fill” function, the picture spread out, but the blur remained. If you reset your monitor settings to default, “Screen Fill” is simply turned off, and the blurriness remains. - Video card drivers are up to date. - The monitor driver is installed (Standard Monitor Driver Signed Windows 7 x64 from the official website). - The resolution is native - 1920x1080. - 60Hz, tried other values, did not help. - Connected via HDMI.
I tried turning off TrueType font anti-aliasing, it doesn’t help, and the blur is not only in fonts.

Blurred image on the monitor
It’s hard to say exactly how many years I’ve been using a personal computer. But I always tried to use LCD monitors. The picture is better on them, and they take up less space. But what is especially characteristic is that everyone sometimes had the same problem, which will be discussed below. The difficulty is that it is a little difficult to describe in words, however, it is worth a try. How can I say this..? Often the image on the monitor seems to be “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 “trail” of the text on the side. (click to enlarge) In order to better understand what we are talking about, let's look at the image on the left, which I specially drew in Photoshop. Since this will not be noticeable on a regular screenshot, a similar effect can only be clearly seen on the screen or photograph. So, we see that the picture is “smeared” or simply repeated horizontally many times, as if when moving. By the way, in English there is such a very appropriate concept here - monitor blur. A similar question has been raised on the Internet more than once (it’s easy to check thanks to Google), but no one has offered a good solution. Of course, the first step 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 helped me out more than once (let me be the captain of the obvious for a little while), is to simply check the cable that goes from the system unit to the monitor. Often these stripes and interference may appear not because of a problem, but because the signal is partially interrupted - just try re-plugging the VGA cable.
This instruction details what to do if you see blurry fonts in Windows 10 or individual programs and applications, which can happen both after changing the scaling in the screen settings, and without these actions.
We'll first talk about ways to fix screen resolution issues that are obvious to most users but may be overlooked by novice users, followed by other ways to fix blurry text in Windows 10.
This item is for those users who do not fully understand what the physical resolution of a monitor screen is and why the resolution set in the system should correspond to the physical one.
So, modern monitors have such a parameter as physical resolution, which is the number of horizontal and vertical pixels on the screen matrix, for example, 1920x1080. Moreover, if you have any resolution set on your system that is not much different from the physical one, you will see distortion and blurriness of the fonts.
Therefore: if you are not sure, make sure that the screen resolution set in Windows 10 matches the actual screen resolution (this may in some cases cause the font to appear too small, but this can be corrected by scaling options).
Note: if you use several monitors (or a monitor + TV) and the image is duplicated on them, then Windows, when duplicating, uses the same resolution on both screens, and for some of them it may not be “native”. There is only one solution here - change the operating mode of two monitors to “Expand screens” (by pressing the Win + P keys) and set the correct resolution for each monitor.
Removing text blur when zooming
If the problem with blurry fonts occurred after changing the sizes of elements in “Right click on the desktop” - “Display settings” - “Change the size of text, applications and other elements” by 125% or more, and restarting the computer or laptop did not fix the problem, try next option.
And the second option of the same method:
After applying the settings, you will be asked to log out, and after logging in you should see the changed sizes of fonts and elements, but without blurring (using this option applies a different scaling than in Windows 10 display options).
How to fix blurry fonts in programs
Not all Windows programs support correct scaling and, as a result, you may see blurry fonts in some applications, while the rest of the system does not experience such problems.
In this case, you can fix the problem as follows:
The next time you run the program, the problem with blurry fonts should not appear (however, they may appear small on high-resolution screens).
ClearType
In some cases (for example, due to incorrect operation of video card drivers), the problem with blurry text may be caused by incorrect operation of the ClearType font smoothing function, which is enabled by default in Windows 10 for LCD screens.
Try disabling or configuring this feature and check if the problem is resolved. To do this, type ClearType into the taskbar search and run “Adjust ClearType Text.”
Additional Information
There is also a Windows 10 DPI Blurry Fix program available online to solve the problem of blurry fonts. The program, as far as I understand, uses the second method from this article, when instead of Windows 10 scaling, the “old” scaling is used.
To use it, just install “Use Windows 8.1 DPI scaling” in the program and configure the desired scaling level.
You can download the program from the developer’s website windows10_dpi_blurry_fix.xpexplorer.com- just don't forget to check it out on VirusTotal.com (it's currently clean, but there are some negative reviews, so be careful). Also keep in mind that the program must be launched every time you reboot (it will add itself to startup.
And finally, if all else fails, double-check whether you have the original latest drivers for your video card installed, not by clicking “update” in the device manager, but by manually downloading from the corresponding official sites (or using NVIDIA and AMD utilities) .
Make sure that there is no mechanical damage on the screen: cracks, dents, signs of impacts.
If there is no mechanical damage, proceed to the next recommendation.
If there is mechanical damage, contact Samsung service center.
Step 2: Run an image test
A picture test will help you check whether the problem is with the TV or the signal.
If there is a defect in the image test, please contact Samsung service center.
If there is no defect, then the problem is in the signal that goes to the TV. If the image is from an antenna, it most likely has a low resolution - it is better to connect satellite or cable HD TV. If the image is from a PC or set-top box, the HDMI cable or video card may be faulty.
Step 3: Reset your TV
A reset will return the TV to factory condition and clear errors.
Check the image after reset.
Step 4: Update your TV's firmware
If there is new firmware for the TV, install it. If there is no new firmware, move on to the next recommendation.
Check the image after updating the firmware.
If the defect disappears, then everything is fine with the TV, continue to use it.
If the defect remains, proceed to the next recommendation.
