Formatting a PC with a broken screen

Hello, I broke my screen a few years ago.
A few days ago, I tried to use a secondary screen in order to be able to use it again; the secondary screen was working fine.
Noticing that there were a bunch of old files, I decided to format it to factory settings.
Today, I can no longer see my screen on the secondary one; do you have a solution?
Thank you.

    Hi

    Assuming that pic means Pc:

    Brand?

    Model?

    Operating system (specific)?

    So you restored it (and did not format) to "factory settings"?

    How did you do it?

    What do you display on the secondary screen?

      Yes, that's right, little typo ????
      It's an ASUS F751L i5 black
      Under Windows 8 I don't have more information than that except for a label that says Windows 8
      Yes, that's right.
      I went into settings then "change PC settings" then "updates and recovery" then "remove everything and reinstall Windows."
      Before, I could use the secondary screen as the main screen, since the original screen is broken.
      Now, as soon as I turn on the PC, the screen stays black and displays nothing (in my opinion, the PC is at the beginning of the restoration so the screen can't display that).
      I tried to do it with several VGA, HDMI cables, several screens too, and nothing works, the problem probably comes from the PC but I can't fix it.

    What is it running on then?

    If you restored it, it has an OS

    In any case, laptops have a key combination that allows you to switch from one output to another, without being under an OS

    For example, mine is Fn + F5 but it's an Acer

    Check the user manual for yours

    If you don't have it, you can find it by searching online with the keywords: ASUS F751L manual

      Good evening Kaumune.

      I think this user hasn't finalized the Windows installation yet because they are blind to accepting the Microsoft contract, the keyboard layout, the language region, and everything Windows asks before reaching the desktop.
      So without being on it, they are unable to retrieve this second screen.
      Am I mistaken in this analysis?

      Maybe, but in any case, with the function keys (Fn + Fx), outside of the operating system, we can also switch the video outputs as I indicated.

      So since I have a PC Upgrade to redo to 10 and this one has a VGA and I have a spare screen, I'm going to set myself up almost like the author and see how it goes on my side.
      But I won't break my main screen to be sure.

      If it works here, it should work for W 8 too.

      I believe we don't understand each other.

      No need for Windows (or any other OS) to switch from one screen to another with the combination of Fn + the designated function key on your laptop.

      Yes. I have the same equipment available, so if it works for me, it will work for him. :)

    It's all good Fn F8

    Did you check each time that the correct source was selected in the OSD menu of the screen?

      Yes, it's always the right one that is selected.

        the good ?? the good what?

        I'm talking to you about the source selection (input) on the secondary screen, using the buttons on the screen

        Source = feminine so it can't be the good one

        (VGA, DVI, Hmd1 Hdmi2 Hdmi3 etc ..etc ....)

        The screen is properly connected with the cable that is connected to the PC, and yes, I have correctly selected the right input (VGA) using the buttons on the screen.
        The problem is (I think) related to the PC and not the screen; I know enough to make the right connections, I just can't manage to transmit my (broken) screen to the second one.

        P.S.: Do you have another means of communication (faster) so we can try to resolve the issue more quickly and save everyone some time?

    Hello,

    So I’m getting back to you, but being on W 10, when connecting an external screen to the laptop, I didn't need to press any key.

    So I’ll leave it plugged in and completely reinstall Windows.

    I’ll see what happens next.

      What would be interesting is if you could describe what happens with Fn + F8 since, I quote you, "it's not under Windows"

      It's the only way he has to switch from one screen to another

      For me, it works with Fn + F5.

        Ah! Sorry, I didn't think to check if I could cut the native one from the Asus. :/
        It shut down as soon as I started the reset, so let's act like mine is broken and wait to see if I'll be able to connect it without the original screen.

        If this goes the same way, of course.

    Well, it's not a big deal if I do a monologue.

    So I'm starting the complete reinstallation.
    It cut off the laptop screen, leaving the largest one as the main display.

    I hope that afterwards, while keeping the secondary screen, none will turn on and I'll see if I need to do something to turn on the external one.

    Now all we have to do is wait for the next events to unfold.

    Well, it's back, I don't know if it's because I left the external screen connected, but it's restarting in a loop telling me that Windows has encountered a problem.
    I removed the 17 inch and the issue is still here.
    I'm reinstalling from the USB drive.

    Well, I removed the hard drive and I see from disk management that the partition where Windows was supposed to install has turned to RAW.
    That's my problem. So I won't have confirmation on how to resolve your initial issue.

    So I'm deleting the partition, putting it back in the laptop, selecting the boot from the BIOS and it's back to installing Windows.

    This allowed me to see that on the supermarket USB drive, I have the option to set it to 64 or 32 bits. :)
    It's worth buying one anyway, even if it's at a high price. ;)

      ???? Are you saying to install in 32 or 64 bits? It depends on the ISO you are using, not the key itself (unless it is too small in capacity of course)

        It's a key bought with the license, so I no longer know how much it is, but at least 4 GB for sure. Otherwise, I'm working hard to fix the laptop. During the reset, it ended up in RAW.

    Hi,

    I confirm that it is important to follow kaumune's instructions and carefully check what he says in messages 16 and 19.

    The key is fn+f8 according to 2 Asus laptop manuals: https://www.manualslib.com/manual/1123474/Asus-X751l.html?page=34#manual and https://dlcdnets.asus.com/pub/ASUS/nb/UX32A/F7165_eManual_UX32A_UX32VD_Z106.pdf page 34.

      I have already done this manipulation several times but nothing changes. I cannot get a response on my second screen.

        Hi,

        Have you tested your screen on another CPU?
        Have you changed the HDMI cable or another standard?
        If you have a multimeter in voltmeter mode or a voltmeter, all these cables have at least one 5V pin and one GND pin. You can measure them with a calibrated multimeter set to over 5V DC. Look up HDMI pinout or another standard to find the location of these pins.

        Yes, I even tried with another screen, I tried several cables (HDMI, VGA and VGA to HDMI adapter too)
        I don't have a voltmeter or anything like that (if I understood correctly, you wanted me to use this to see if the cable was working well?)
