Is the frequent black screen on the phone related to the high screen refresh rate?

It's not about swiping the screen.

There are many reasons why your computer has a black screen. Let's see if there is no power supply and whether the display is too dark. Eliminate these factors and then find fault with the host.

See if the reset key doesn't pop up, so that the computer is always in a reboot state. There is also a power on the CMOS to restore the default value of the relevant CPU settings, because it may be a black screen caused by the soft super CPU frequency in the CMOS that the CPU cannot be lit. There is also the graphics card, memory, and CPU plugged back in, especially the AGP graphics card, which is easy to warp, all because the quality of the current chassis is too poor, and it will be deformed in a casual flash, resulting in the board being out of place.

There is also the fact that the computer cannot boot due to the rewriting of the BIOS after the outbreak of the CIH virus. This needs to be treated on a case-by-case basis.

From what you're talking about, there's nothing wrong with setting the refresh rate on the display. After you turn on the computer, however, the computer is running, and the monitor does not show it, which is the resolution of the monitor that you have set.

At that time, the resolution of the set display was too high. That's where this happens.

Workaround:1After the PC starts up, you set the refresh rate again, don't set it too high. 60 is also enough.

2.If you can't start the computer directly, restart the computer with a higher resolution monitor and adjust the refresh rate to 60Shut down, replace the monitor in your hand and install it on the main unit, restart the computer and it's OK.

It may be related, but first we have to see if your graphics card driver is going to be updated!

Then see if the working frequency of the graphics card supports 75, and there are bit color settings!

65 or 70 Hz is recommended for LCD monitors!

It's not good for the hardware!

And you can't feel it with the naked eye!

If it is related, it can be adjusted to 60.

Relevant – especially if the display is not of high quality or is problematic.

Never mind. 1 Check that your graphics card driver is correctly reinstalled.

It has nothing to do with your refresh rate

You have a problem with the resolution, jump off.

There are several factors that lead to a black screen:

Power management settings. The system is set up incorrectly. Third-Party Software Settings. The graphics card is overloaded. The temperature is too high. and so on.

If you think it's a problem with the refresh rate, adjust it to the appropriate frequency and see if there is a fault, if it's a driver problem, it's best to use the original driver of the graphics card delivery, if not, use other drivers on the Internet to see if there is a fault.

The reason for the graphics card, 1. Install the official driver of the graphics card. 2. Check whether the graphics card has a capacitor bulge. 3Try to replace the graphics card, I analyzed that it is likely to be a hardware failure of the graphics card.

No, this kind of problem is no longer present with today's hardware and systems.

Fifteen years ago, if the matching resolution of the computer hardware and system was not adjusted well, then the boot would not be displayed.

Let's reinstall the system.

It should be a driver issue.

Restart the computer, press F8, and the selection menu will appear. Select the last correct configuration, try the safe mode, and if you can enter the safe mode, you can uninstall the recently installed software or drivers. If this is still the case, the system will have to be redone.

There are many reasons for the failure of a computer's black screen, such as a damaged monitor, a damaged motherboard, a damaged graphics card, a bad contact of the graphics card, a damaged power supply, a damaged CPU, and a high temperature of components. There are also artificially caused by the black screen of the computer, such as the genuine verification of Microsoft China.

There is a signal on the black screen of the computer, but you can't enter the system interface normally, observe the keyboard working indicator to turn green, use the U disk PE system, use the shortcut operation with the help of the U disk PE system to see if you can enter the PE system interface normally.

The first reason is that the slots of the graphics card and the motherboard are not fully contacted, resulting in the phenomenon of stripes, suggested: just turn off the power, open the chassis, take out the graphics card, use the eraser to wipe the gold finger a few times, and then reinstall it back, sometimes deal with it like this, just start it again.

I don't think so, it's probably a virus in the computer, or a problem with the graphics card hardware.

Turn on the computer, click the F8 key, create a security mode, scan for computer viruses, and clean the registry and junk.

If you can't solve the problem, it is recommended to find the official customer service, ask how to restore the system, and do as they say.

If it doesn't work, you have to find a maintenance master, and it is likely to be a hardware problem.

Press F8 immediately after booting up, see if you can enter the safe mode or configure the correct mode for the last time, if you can, it will automatically repair the registry after entering, and recall what you did when the first few abnormal phenomena occurred, and according to the suspicion that a certain application software caused the problem, uninstall it, and then exit normally.

Look at the description should be driving the display of the graphics card for these three reasons.

First, from the 64hz frequency, the maximum is likely to be the cause of the drive, enter the safe mode to uninstall the driver, and use the default driver of the system to see if it is normal?

2. Eliminate display failures.

Third, the graphics card problem is troublesome, because it is an integrated graphics card, you can consider using the independent graphics card to see if the problem is solved?

The security mode is normal, but there is a problem with the system, and the driver is mostly due to the problem, and the driver is ruled out as a problem with the graphics card.

Look at the questioner, I know the computer, and I have so much, do this - don't worry, you have to be calm!

One. 64hz definite question. Can you modify it back to solve?

Two. Or, uninstall the graphics driver first - attention! It's F8 into safe mode, uninstall! Reload.

Three. If it doesn't work, reinstall the system. Note! Before you redo the system can't work, maybe the installation disk can't.

Four. It's likely that there is a hardware conflict! After installing the driver, the screen continues to go black - the version of the driver is wrong! Should be able to work it out.

If you can, solve the problem, please adopt it. Thank you!

Summary. The first option is to restart your computer into safe mode.

Restart your computer and wait for the screen to appear"starting windows"press F8 immediately, (some computers display the operating system list for too short a time, then press F8 in advance, or it is easy to skip the screen of selecting the operating system and restart the computer) Select the third option"safe mode"Safe mode boots, after entering Windows, the recovery system window will appear, dot"Nope"to go to the desktop. What I want to remind here is that when you enter the safe mode, the computer starts slowly, generally ranging from 3 minutes to 10 minutes, so, after restarting the computer, you choose the safe mode, there is a black screen for a while, only one cursor is flashing, please don't think it's dead, don't press any button of the host, this is normal, you just need to wait patiently, the time may take 10 minutes, and the computer enters the safe mode, and the monitor appears windows. Once the safe mode is started normally, we can execute:

Start -- Settings -- Control Panel -- Display -- Settings (screen resolution to minimum) -- Advanced properties -- Refresh rate, set the refresh rate by"Unknown"Tune into"Adapter default or minimum"--Are you sure. Then restart the computer, the black screen is gone, you can continue to debug to find the matching resolution, but be careful, don't adjust it too high and the black screen will be black.

The computer turned black after adjusting the refresh rate.

I'm still a little confused, can you be more detailed?

Then restart the computer, the black screen is gone, you can continue to debug to find the matching resolution, but be careful, don't adjust it too high and the black screen will be black.

Turn on and press F8,Then there's a start VGA mode.,After entering, adjust the refresh rate and resolution to try to disconnect the second display.,Connect it again after a while.。 Detailed solutions: 1. Modifying the resolution without authorization usually leads to an error in the display and pops up

Prompts that are out of the operating frequency range. 2. At this time, do not move any settings, the system will automatically return to the previous resolution without the user confirming the operation. 3. If you can still enter the operating system, then enter it in operation:

OK, turn on the settings item for setting resolution to return the resolution appropriate for the current display (usually down). 4. There is also a situation where the user modifies the refresh rate (up) without authorization, which will also cause the display screen to appear: a prompt that exceeds the working frequency range.

Adjustment method: Advanced setting of the monitor screen refresh rate 60 OK. 5. If it suddenly appears in the middle of a game:

Hints that are out of the operating frequency range can be adjusted back to the game's settings using the property. 6. General set the startup options. 7. If there is already a parameter in the startup options, delete it.

Add it again (with a space in between): freq 60 OK. 8. If it is displayed after restarting the computer:

Prompts that are out of the operating frequency range. Then press and hold the power button for the first time, turn off the computer, then press the power button, restart, press the F8 key immediately, and use the up and down keys to select: enable VGA mode (usually only available in the boot management menu of Windows XP operating system).

9. If you don't enable the VGA mode menu (such as Windows 7 operating system), you can try to enter the safe mode, uninstall the existing graphics card driver, restart the computer system will automatically recognize, reinstall the graphics card driver, then the resolution and refresh rate are the correct defaults. 10. If you can't even enter the safe mode, then you can only use the U disk PE system or install the CD to repair, restore and reinstall the system. 11. If even reinstalling the system can't solve this problem, then there must be a problem with the graphics card hardware.

12. There is also a possibility that the power supply and monitor socket are not plugged in properly, just plug it in again. Method 2: 1

If you can't solve the problem after trying various methods, you can use the reinstall system. 2.The operating system in the system home is suitable for new operations, and the fool operation is very simple and easy to use!

3.Computer tutorial (the system is safe and stable, green and smooth, can be in the system home** We need the operating system: >> desktop win10 64-bit system**<<> desktop win10 32-bit system**<<> notebook win10 64-bit system**<<> notebook win10 32-bit system**<

The solution to the black screen caused by the display refresh rate setting being too high.

1.Delete C: Windows System32 Config System under DOS, then restart and reinstall the system driver.

2.Press F8 when booting up, choose to start with, and then reset the refresh rate and restart.

3.Press F8 when booting, select Safe Mode to boot, delete the graphics card driver, restart, and reinstall the graphics card driver.

4.The dumbest way: reinstall the system.

There are many methods, the most primitive is to reinstall the system, but this is too troublesome, and if the original installed software has to be reinstalled, it is time-consuming and laborious, although this method can be solved, but it is not cost-effective, so this method is negative.

Another way is to directly find a monitor that supports high resolution and high refresh rate, which can be solved, but if you only have one monitor at home, it is not realistic, so it is not realistic to borrow one, so this method is also negative.

Since these methods are negated, then is there a simpler and more convenient way, the answer is of course yes, the following is to introduce if it is solved, first of all, the computer is black, with the mouse and keyboard operation will not be displayed, press the reset key to restart, after restarting, quickly press and hold the F8 key do not reach out, enter the safe mode, some computers are not good, but the current ghost system has two startup items, if you do not enter the safe mode, but when you see two startup items, the general default is 5 seconds, At this time, you quickly press the down button of the right arrow key, and then press F8, you can enter the safe mode, then you select the top one to enter the safe mode, and then choose to enter the system, enter the system may take a long time, wait for a while.

After entering the system, it will prompt whether it is running in safe mode, select Yes, after entering the desktop, click on the right-click properties of my computer, and then enter the Device Manager, click on the display card below, open, the model inside is the graphics card driver you installed, directly right-click to uninstall, OK, restart the computer after uninstalling, is it already possible to enter, and then follow the prompts of the system, reinstall the graphics card driver (according to the prompts, click Yes, generally automatic).
