As known, the display cables, also known as Display Cables, have three main signal sources: 0V, 3.3V, 5V. When loose, exposed, or faulty, they often cause difficult-to-view screen errors, sometimes resulting in severe interference or complete inability to view anything. Therefore, in some cases, loose, exposed, or faulty display cables can lead to laptop screen interference, affected by mosquitoes.
- Laptop screen interference, mosquito infestation due to high-voltage boards
High-voltage boards, often referred to as LCD Inverters, are responsible for generating voltage to illuminate the high-voltage lamps. If they malfunction intermittently, sometimes working and sometimes not, they can likely cause laptop screen dimness, darkness, or even erratic behavior. This can also be a contributing factor to laptop screen interference, affected by mosquitoes, to a lesser extent.
- Unstable power supply
If your laptop has been in use for a while or unfortunately suffered from strong impacts, pressure, or falls, it may result in a glitchy screen, making it as hard to see as mosquitoes buzzing around.
- Incorrect screen refresh rate
Usually, the screen refresh rate is around 60, 70, 75Hz. If the refresh rate is incorrect, it can lead to screen interference. However, this issue often occurs in low-spec or outdated computers.
Ways to fix a glitchy, mosquito-like laptop screen
When encountering issues like loose or faulty monitor signal cables, weak high voltage strips, unstable power supply, or demanding graphics cards that require certain expertise to tweak, you can definitely handle adjustments on your own. In case of difficulty, seek assistance from knowledgeable individuals or reputable repair shops where you purchased the device or reliable repair centers.
- Attention
- Before sending it for repair, you can try using another computer monitor and connect it to diagnose the underlying causes more thoroughly.
For inaccuracies in the screen scan rate, you can make adjustments accordingly. Right-click on 'Desktop => Properties => Settings => Advanced => Monitor' to adjust the appropriate level. As mentioned earlier, the screen scan frequency should be around 60, 70 to 75Hz.
