Nowadays, the usage rate of LCD screens is increasing, and different problems may be encountered during use. Technology is a professional manufacturer of high brightness LCD screens and outdoor high brightness screens, and has made some summaries for a series of problems. Next, the editor will introduce the methods to solve the problem of LCD screen distortion.
1： Firstly, we need to check if the connection of the LCD display screen graphics card is loose. The most common phenomenon is the appearance of "clutter" and "dots" on the screen due to poor contact.
2： Check if there is excessive overclocking on the graphics card. If the graphics card is excessively overclocked, irregular and intermittent horizontal stripes usually appear. At this point, we need to appropriately reduce the amplitude of overclocking. Note that the first step is to reduce the graphics memory frequency.
3： Check if the resolution or refresh rate of the LCD display screen is set too high. The resolution of LCD displays is usually lower than that of CRT displays. If it exceeds the manufacturer's recommended optimal resolution, there is a high possibility of screen distortion.
4： Check if the anti electromagnetic interference and electromagnetic shielding quality of the graphics card are qualified. The specific method is to install some components that may cause electromagnetic interference as far away from the graphics card as possible (such as the hard drive), and then check if the screen has disappeared. If it is confirmed that the electromagnetic shielding function of the graphics card is not satisfactory, it is recommended to replace the graphics card or make a self-made shielding cover.
5： If after using the above five techniques, the problem still cannot be solved, then it is likely a quality issue with the LCD display screen. At this point, it is recommended to replace the LCD display screen with another one for testing.
