LED videowalls is currently the market's most popular display screen, its application areas have spanned entertainment, security, broadcasting and other industry sectors. Blurry screen is a more common failure of the LED videowalls, once the LED videowalls blurry for the LED videowalls overall full HD display effect has a great impact.

What does screen blur mean? It means that there is an image on the screen, but the image is covered with dotted, flaky, mosaic interference, which then the screen becomes blurred and indistinct. Then once such a problem when we how to solve it? The following CY Digital Signage professional technical engineers to analyze how to solve the LED videowalls becomes fuzzy. 


1. Check whether the connection between the LCD video walls and the display card is loose. Poor contact will lead to screen "Messy" and "Patchy", which is a relatively common phenomenon. We need to carefully check each place of the connection line, has been loose connection line, we can try to unplug it and then re-insert the connection, and finally turn off the video walls power line and restart.

2. Check whether the graphics card is overclocked. If the graphics card overclocked, there will be irregular and intermittent horizontal stripes. At this time, the overclocking range should be properly reduced. Please note that the video storage frequency should be reduced first.


3. Check the quality of the display card. If the problem of flickering screen after replacing the display card, the first and second measures are invalid, check the quality of the display card's anti-electromagnetic interference and electromagnetic shielding is qualified.

Specific measures are: install some components that may generate electromagnetic interference, as far away from the display card (such as hard disk), and then see if the problem of the screen has been solved. If it is determined that the electromagnetic shielding function of the display card is not enough, the display card should be replaced or homemade shield.

4. Check the LCD video walls resolution or refresh rate is set too high. The resolution of the LCD video walls is generally lower than that of the cathode ray tube display. If more than the best resolution recommended by the manufacturer, the screen may appear. At this time, we need to turn down the resolution, or consult the manufacturer how to solve. CY Digital Signage Team is available to answer your questions 24/7.


5. Check whether the installation of incompatible graphics card drivers. Generally speaking, this situation is easy to ignore because graphics card drivers are updated more and more quickly (especially NVIDIA graphics cards), and some users can't wait to install the latest version of the driver.

In fact, some of the latest drivers are either beta versions or versions optimized for specific graphics cards or games, and using these drivers can sometimes lead to the appearance of splash screens. Therefore, it is recommended that you try to use Microsoft, certified drivers, preferably using drivers provided by the display manufacturer.

6. If the above five measures still cannot solve the problem, there may be LCD LED videowalls quality problems. At this time, please replace other displays for testing. If necessary, find a professional manufacturer for help and support.
