OK, first off I believe this is a Windows 10 problem, if It's not then I apologize.

My laptop screen is not working, I get the ASUS logo when I turn the laptop on, but then the screen just goes black. I usually connect the laptop to a separate monitor and that shows windows, so the laptop itself is working fine, but the monitor is not and stays off regardless of the settings I use on the monitor project settings.

I do not know if someone else can determine exactly what you mean but I am confused
Your thread title is

Laptop screen not working
but in your post you say
My laptop screen is not working, I get the ASUS logo when I turn the laptop on, but then the screen just goes black. I usually connect the laptop to a separate monitor and that shows windows, so the laptop itself is working fine, but the monitor is not and stays off regardless of the settings I use on the monitor project settings.
so are you saying that AFTER the Asus logo, both the laptop display AND the external monitor, do not then show any display
OR are you saying that after the ASUS logo the laptop screen does not shown any display, and the external monitor is OK


TRY disconnecting external monitor
then on powering on laptop
press the Windows logo key
, the Ctrl key, the Shift key and B at the same time.

This could be a driver issue, the Asus logo is displayed using the basic graphics driver and after that the Windows driver is used

I suggest if the key combo does not work, your next step would be to boot to recovery on windows 10 advanced trouble shooting startup settings and select SAFE mode with networking or low resolution mode - these may also allow the display to function using a basic graphic driver.
(1) Boot to Advanced Startup Options in Windows 10 | Tutorials (tenforums.com)
The link is from another site I work on and will provide you with the full guide as to how to boot to advanced startup
I suggest you try
option 6
and then proceed if you get to recovery as shown at the images at the start of the link
startup settings
safe mode with networking and if that does not work
low resolution mode

IF neither works or you cannot get to recovery we can proceed further when you reply,

No, sorry for any confusion. The external monitor works fine. Shows everything. The laptop monitor does not, it shows the ASUS logo when starting up the laptop, then nothing. I have tried disconnecting the external monitor and the HDMI cable. I have tried changing the project settings to all available options. None of these work. I will attempt the boot in safe/low-res mode and will let you know how it works out tomorrow. Much thanks :D

OK I tried the Windows key, CTRL, shift and B, and it did nothing. But when restarting in safe mode, the laptop monitor works. Of course, as soon as I restart in normal mode, it doesn't work again. It's clearly an issue with windows, I think.

It is likely to be the driver
elect SAFE mode with networking or low resolution mode - these may also allow the display to function using a basic graphic driver.
try low resolution mode if it works then, that would tend to confirm the driver

OK, restarted in low res mode and I got the windows login screen for about 2 seconds on the laptop monitor, and then it went black again.

Go here on another computer
Download Intel® Graphics - Windows® DCH Drivers
on the left hand column download the exe file -
igfx_win_100.9684.exe
save it to a USB pen

Now back on the Asus
Go back to Safe Mode
and when in safe mode go to device manager
In device manager expand dispay adapters
you should see the Intel UHD620
right click and then click uninstall device
on the window that opens click to check delete driver software

RESTART the laptop
it should load a windows basic driver for the graphics when it finds the new hardware
Insert the USB pen and run the exe file to install the driver that you downloaded from Intel
