    Windows 8.1


    Thank you to everyone here - I had the exact same nightmare today, and after calling Samsung (who was useless) I was left to find my own answers. As others have pointed out that updating both the Intel display drivers, and Radeon drivers to 8.1 more or less solves the problem. But - now I have a new one. I can't adjust the brightness???? The function keys display the purple adjust slider, but nothing happens. If I try to use any of the various control panel locations in Windows 8 (including the charm bar) - nothing happens. I can only assume this is driver related, can anyone help please???

    Ok so I figured out what caused my brightness control to disappear, it would seem the latest Intel 4000 drivers (remember this thing has 2 graphics cards - good times huh?) are not compatible with ACPI brightness controls. You do have to update the latest AMD Catalyst drivers, which appear to be the reason why you hit a black / flickering login screen.

    I installed the beta driver 13.11
    AMD Catalyst? Display Driver

    Here's all of the steps for anyone that's reaching the black-screen of death on Chronos 7 Windows 8.1 upgrade:

    Restart and HOLD shift-f8 to get into safe mode.. How To Boot Into Safe Mode On Windows 8 (The Easy Way)
    Choose Safemode+Network support so you can download the Radeon 13.11 drivers above
    Install these while in safe mode, you should be set.
    Restart the computer - Windows Login screen should be fine.
    Now do a BIOS update if you can - this doesn't seem to work in safemode.

    If you've already installed the newest Intel-4000HD drivers, or had to in order to get 8.1 kicking - and want rid of them so brightness controls work this can be done inside "SW Update" from samsung, there's a secret menu of sorts in there:

    Lower left corner: "Find Model" - choose NP780 or whatever you have..
    click Windows 8
    A strange sort of Export tool appears, Uncheck All by using the checkbox at the top
    Scroll down and choose "Graphics Driver 64" - this is not AMD driver, don't select that

    Next you'll be prompted to save this to your desktop.. the tool will basically download the old HD4000 driver you need. Once on your desktop, browse to the folder and install it. Brightness controls will be restored correctly.

    Thanks to everyone who contributed to solving this issue after Win 8.1. I am still having the blurry text issue, having updated the intel HD4000 driver & complete rebooting (shutting down) hasn't helped so far.

    the only thing I didn't mention that I did before I completely shut down the computer (solving my blurry screen) was that I downloaded and re-installed the amd graphics driver again. I'm not sure if that actually did anything but it's worth a shot...

    I will have to try your steps for getting the brightness control back. I thought maybe I was just unlucky and had some other issue with brightness control. Thanks.

    1. Enter Safe mode with networking

    3. Go to your device manger, disable your AMD graphics card.
    4. Restart. It'll load in normally.
    5. Run the installer.
    6. Restart.

    Hopefully that'll work for you too. AMD just apparently hasn't updated their mobile drivers for windows 8.1 yet.

    Only thing now is the display is kind of dim. Im trying to figure out how to fix that now though.
    Thanks. That help me solved the issue that I have.
    To enter the safe mode, that the most difficult part for me.
    Keep on pressing F8 and Shift+F8 did not work.

    How I managed to go into the safe mode :
    1. Whenever the boot screen disappear and screen goes blank (Windows starting), I pressed the power button until computer went off (Forcing Shutdown)
    2. Turn on the computer
    3. Repeat step 1

    after few times, Windows automatically restarted in Advance Startup Option because It detect that something wrong with the Windows because it cannot start up properly.

    From there, just select Troubleshoot - Advance Setting - Startup setting, then the computer will be restarted in Safe Mode.

    Btw, my computer is Samsung 7 Chronos - NP770Z5E

    How exactly are you guys installing/uninstalling stuff while in safe mode? It refuses for me, saying something like the installer service blah blah blah.

    Success! I managed to get it working by downloading and reinstallling the Intel HD4000 drivers as per laloindublin's instructions above BEFORE the catalyst AMD drivers. This then allowed me to reboot in normal mode, and then install the catalyst drivers (had the driver detection error in safe mode).
