What should I do if the ASUS monitor is black and unresponsive?

Answer 1

If the ASUS monitor is black and there is no response, you can check it according to the following methods:
1. ** Checking connection **
- Check if the monitor is connected properly. When the monitor is powered up, it should sound normally, and the power indicator light is on. If there is a "hissing" sound when moving to the monitor screen and the hair on the back of the hand stands up, it is a normal power-up reaction.
- Check whether the display signal cable and the display card are in good contact. Dirt, broken needles, or other damages at the interface may cause poor contact and black screen.
- Check if a standalone graphics card is used. If so, make sure the signal cable of the display is connected to the standalone graphics card instead of the integrated graphics card interface.
2. ** Checking hardware **
- Check the power supply of the host: check whether the power indicator on the panel of the host is on and whether the power fan is running to determine whether the host is supplied with power; check whether the external voltage meets the requirements with a universal meter. If the voltage is too high or too low, it may cause the host power supply to be over or under voltage. The circuit will automatically shut down for protection. Also, check the quality of the power switch and reset button and whether they are connected to the main board correctly. If the power supply is damaged, replace the power supply.
- Checking the display card: Check whether the chip on the display card has any scorch or crack marks, whether the cooling fan is working and whether the cooling performance is good. You can also change a normal working display card to eliminate the possibility of damage to the display card. Check whether the contact between the display card and the main board is good. If the display screen is black and the speaker in the host makes a long and two short beeps, it may be that there is a problem with the connection between the display card and the main board or the display. You can check the slot contact and whether there is any foreign matter in the slot. Change the main board slot for testing.
- Check the memory bank: If the computer starts up with a black screen and the host makes continuous beeps, there may be a problem with the memory bank. Check the connection between the memory and the memory slot, and then plug in the memory bank again or replace the memory bank.
- Check whether the fan in the case is running. Damage to the cooling fan in the case will cause poor heat dissipation. In serious cases, it will cause damage to the CPU and other components or the computer will automatically shut down and alarm.
- Check whether the sockets of other boards (such as sound card, compression card, video card, capture card) and the motherboards are in good condition and whether the drive signal cable is connected correctly. The installation of sound card and other devices may cause the system to be difficult to complete, especially the hard disk data cable interface problem may cause no display fault.
- Checking the CPU: Check whether it is overclock, whether the CPU is in good contact with the main board, and whether the CPU cooling fan is in good condition. Overclock caused the black screen to jump the CPU back to the original frequency; if the connection was bad, remove the CPU and re-install it, and use a high-quality high-power fan to dissipate heat.
3. ** Software-related **
- If you press the F2 key to enter the BOSS interface, the display is normal. You can try to press the F9 key to restore the default values in the BOSS interface, then press the F10 key to save and exit, and restart the computer. If it is ineffective, it may be a system or driver software problem. Try to restore or re-install the system after backing up the data.
- If you suspect that a virus is causing the monitor to black out, you can use the latest version of anti-virus software to deal with it. Sometimes, you may need to rewrite the BIOS program.
4. ** Other situations **
- For some 440 standalone displays, if there is an external power supply port (the power supply is six PIN), you need to check if it is plugged in.
- If you are using a laptop, pay attention to the type of screen (wide-screen is divided into high and normal), and set it to automatically obtain the resolution. If you can hear the boot sound, under normal circumstances, the monitor may be broken or not plugged in properly. Check carefully.
- If the power used is insufficient (such as less than 300W standard), it may also cause a black screen. You can try to borrow a friend's power supply.
- Some Asus notebooks/all-in-one computers can try to reset the battery: remove all external devices and shut down; remove the power charger and battery (non-disassembled batteries do not need to be removed, specific models such as TP420ia and U4700ia do not need to perform this step); press the power button for 40 seconds; re-connect the battery and charger (if removed before) and turn it on. Wait patiently for the computer to complete the memory training and enter the operating system. There may also be a situation where the CPU cannot be turned on due to the failure of the CPU update. If there is a relevant prompt screen, follow the prompt to complete the CPU update before turning on the CPU.
- The notebook can also try to press the Fn + F6 combination function key, increase the screen brightness, and press the Fn + F7 combination key to switch the display on/off.(To prevent the screen from being too bright or turning off the screen to cause a black screen); You can also connect an external monitor and press the Fn + F8 key combination to switch the display; Power on and power off three times in a row, enter the system recovery environment, choose [Trouble Answer]-[Advanced Option]-[Start Setting], click "Restart"-[Activate Safe Mode], and then unload the recently installed software and drivers.
