    Make Win10 treat laptop LCD screen as external monitor, possible?


    Hello, I've been having this new issue with the latest nvidia driver update where all options from nvidia control panel were removed, except for 3D settings. Using DDU and rolling back to old versions did not fix it at all.
    Those settings are restored once I plug an external monitor, but I don't have my external monitor anymore, so I need a workaround. Do you think it's possible to make windows recognize my laptop monitor as an external one? Thanks in advance.

    If the laptop has HDMI out, plug it into a TV.

    Most Notebooks have a key combination of Fn + another Fx key that toggles between the LCD Flat Panel, an External monitor/Projector or both at the same time. It's important to know that, except for the input of a Touch Screen panel, there is no other input available like from a Desktop computer, think one-way road. There are programs like LinkedIn that allow access to a computer from another computer that may accomplish what is needed but then you may have to have a display on both machines to set the program/s up. But a question arises, if the other computer doesn't have a monitor how does it boot up? I have seen computers on a network some years ago not need a monitor to boot up, was adjustments in the BIOS that allowed it.

    I read the main topic. I did say "if" you have a TV. Not everybody knows a TV can be used as a monitor.

    Hopefully I do, nevertheless even if I did have a TV it wouldn't really be convenient to sit right next to it and keep my HDMI cable plugged in order for me to play video games. By the way we don't have a TV in my dorm.

    Interesting, about the BIOS ajustments thingy; mine is unfortunately locked and until this moment it couldn't be modded by anyone on bios modding forums so I'm afraid that's not an option.

    If push comes to shove one could try to locate the CMOS battery [stores the BIOS settings] and remove it, the main battery and AC adapter for maybe 10 minutes, usually removes the assigned setup and login password/s to give a cleaner startup. But it takes a great deal of patience and some experience taking the case apart to get to that battery.

    Wouldn't that reset the BIOS settings to the default ones set by my laptop manufacturer? If so wouldn't it still be locked? (I might have been unclear at the start, but by locked I mean you can always access bios settings but you're only given basic settings http://www.notebookcheck.net/fileadm...ll-HD/bios.jpg )

    The only times I come across a "locked" BIOS has been because someone set a password on both the startup/logon function and the ability to change settings. These settings take place before any OS/Operating System loads. I have seen other instances where a company had Notebooks on a Server-based Network and removed them before disabling the security of the Network, essentially made them useless until removing that password and installing cleanly a supported OS, did tend to take away the free donation intended for them [IBM and Lenovo ThinkPads with Vista] due to the expense of a new OS.

    Removing the CMOS / BIOS battery in a laptop may reset some settings, but it won't reset any BOIS passwords. Those settings are saved in an EEPROM. It doesn't lose any info when power is removed like what happens in a desktop PC. Thats done on purpose to make getting by those passwords very hard if its lost or stolen.
