Common faults and solutions for LCD splicing

[ Pacific Security Network News ]

LCD splicing has gradually matured in China, and there has been a great breakthrough in technology, but there are still some stains in the process of use. Below I teach you how to solve the common problems of LCD splicing.

The gradual maturity of the LCD splicing market is not only reflected in the advancement of product technology, but also in the breakthrough in market applications. For example, digital signage display, outdoor super bright LCD splicing, large security command center applications, etc. These new application areas not only expand the market scope of the LCD splicing industry, but also enhance the taste level and profit level of the overall market.

Common faults and solutions for LCD splicing

One: Check if the connection between the LCD splicing screen and the graphics card is loose. Poor contact can lead to "clutter" and "noisy" patterns are the most common phenomenon.

Two: Check if the graphics card is overclocked. If the graphics card is overclocked, irregular and intermittent horizontal stripes will generally appear. At this time, the overclocking range should be appropriately reduced. Note that you should first reduce the memory frequency.

Three: Check the quality of the graphics card. If there is a problem with the flower screen after replacing the graphics card, and after the first and second strokes are not effective, check whether the anti-electromagnetic interference and electromagnetic shielding quality of the graphics card pass. The specific method is to install some components that may cause electromagnetic interference as far as possible from the graphics card installation (such as the hard disk), and then see if the flower screen disappears. If it is determined that the electromagnetic shielding function of the graphics card is off, you should replace the graphics card or make a shield.

Four: Check if the resolution or refresh rate of the LCD splicing screen is set too high. The resolution of the LCD splicing screen is generally lower than that of the CRT display. If the optimal resolution recommended by the manufacturer is exceeded, the phenomenon of blooming may occur.

Five: Check if an incompatible graphics driver is installed. This situation is generally overlooked because the graphics card driver is getting faster and faster (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 optimized for a particular graphics card or game. Using such drivers can sometimes lead to screens. Therefore, it is recommended that you use Microsoft-certified drivers as much as possible, preferably using the drivers provided by the graphics card manufacturer.

Six: If you can't solve the problem after using the above five strokes, there may be quality problems with the LCD splicing screen. In this case, please replace the other monitors for testing.

Vinyl Ester resin have got both advantages of Unsaturated polyester resin and Epoxy Resin, including excellence corrosion resistance of most acidic and alkali chemicals ; more strength and mechanical properties; superior operability and environmental durability.

Vinyl Ester Resin is considered to be a hybrid of polyester and epoxy resins-meaning its handling characteristics, properties, and even price generally fall just between the two.

Vinyl ester is formulated for maximum corrosion resistance to most fuels, vapors, and chemicals.
It's heat resistant and blended for durability.
It features excellent impact strength and high tensile elongation.
It's low viscosity, so it's easy to pour and just right for vacuum infusion.
