    No, just follow the instructions;
    1. create bootable usb stick with linux+tools
    2. boot usb stick (live os)
    3. flash edid (run the 0-255 dump first)
    Iirc the SEC5044 was present in the image, but it doesn't matter; from within the live linux usb stick you'll have access to both local drives and internet (most lan+wifi drivers are included). So could try this edid version first and if it can be flashed, but still says 'incompatible screen' then it's a simple matter of finding the 'approved' version of the edid and flash that.

    OK, I got that to install and boot, and it could read my panel EDID. (It ended up being on bus 9.) It looks like it has 256 bytes for the EDID, so the 5044 should fit when I try that. I didn't actually write anything yet, because I wanted to check with you first and show you what I saw.

    My EDID looks like this:
    0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef

    Well, I "bit the bullet", and did this command:

    sudo bash ./write-edid-256.sh 9 SEC5044_eDP_dd_2012.bin

    It seems to have overwritten the EDID with that one... *and*... It still doesn't get me into 3D mode.
    Same error from the NVidia 3D tools saying my panel isn't supported for 3D.

    You might need to re-install the monitor in windows as well before the driver's aware of the change. At any rate; it can't get it's information anywhere else, the edid is it. However, as mentioned before; there's multiple edid versions for the same panel (only have this version) and we don't know which is being checked for in (v)bios. Try and find someone with a working 3D SEC5044 and ask for the edid (and the vbios while you're at it).

    Kudos for managing to get that thing flashed so soon btw, nice job! And yes, it was fine to flash it since the LG also had an extension block (another 128 bytes), which can be deduced from the '01 27' at the end of the first block. The '27' is the checksum and the '01' means there's 1 extra block of 128 bytes. Good news is that the Samsung edid works as expected for the LG panel, so the other SEC5044's are safe to flash as well.

    So, I deleted the monitor info from windows device manager, and to make sure it wasn't just grabbing it from the registry I used "psexec" utility to run regedit at ultimate superuser and then deleted the HKLM\SYSTEM\CurrentControlSet\Enum\DISPLAY key so that there was no more registry info.

    I then rebooted my machine.
    And it created DISPLAY\LGD02C5 with what appears to be my original EDID back again. So maybe the linux utility didn't actually write out the EDID, or maybe the system somehow reverted the EDID back again. I am going to try reflashing it again with the SEC5044 file and take closer note of exactly what the response said.

    Yeah, I just tried again. Although the script cruised through saying it was writing all 255 bytes of the 5044 EDID, it then read back the EDID and just got my original info back. So, I guess my EDID is "write protected" (at least from this method.) Is there a way to "un write protect it" or am I SOL for this method?

    Plan B will be go back to seeing if there is a way to whitelist this display in the vBIOS (seems like a very long shot), or buy the (not as good) 3D panel designed to go with the r4 model.

    Hmm... I was reading about sView 3D player here:
    http://www.mtbs3d.com/phpbb/viewtopic.php?f=3&t=9990&start=30
    sView came with some EDID checker that produced this output on my system:

    Odd that it says "No stereo" because the panel came from an Alienware M17 r3 where it was working for 3D when paired to a GTX 580m
    I can see the 3D emitter in the bezel.
    The NVidia 3D stereo emitter service is installed and running on my system.

    Hi, I've been watching this thread with interest :).

    I went along a similar path trying to get it to work on my X8 after liking the 3D a lot on my R4. I never got to the point of EDID editing (or even looking!), but I did buy a 3d kit thinking that somehow it would work with a 120hz panel, but no. It seems that laptops are fully locked down to a specific machine, card, and panel combination. The 680m should work in the R3 but some licensing scheme appears to come into play.

    I had the emitter installed but the panel failed the installer test. Really annoying as when I tried it on a ROG Swift it worked great. I do know that the bios editor guys briefly looked at somehow activating the 3D but it came to naught.
    I wish you the best of luck.

    Strangely enough, that is the same for all 3D panel's edids I've seen.

    Just thought of something; the R4 is Optimus, isn't it? If so then the it has to run in dGPU-only in order to flash the edid. Supposedly Optimus can still be disabled on this system, fortunately. Failing even that, due to a hardware lock, then it's also possible to flash it directly with a programmer, same as with rescuing a system with a bricked bios or vbios.

    In my case, I have disabled the onboard Intel GPU in BIOS, and so my only VGA is the NVidia.
    I don't think Optimus is involved here, but some forums I was reading did talk about Optimus issues with the Dell Alienwares. I had hoped I wasn't subject to that since I had the Intel GPU completely disabled, and all graphics go to the NVidia.

    Last night I did a bunch of Nvidia driver experimenting, rolling everything back to the old Dell Support site NVidia drivers, trying the latest from NVidia's web site, etc. The results were always the same.
