    Hello,

    So it's been a while since I had this issue, it didn't bothered me that much at first, but I decided it's time to do something about it because it really started to get irritating.

    The issue comes from the way the GPU sees its outputs as primary and secondary from the GPU bios itself.
    What I mean is, when my PC is completely turned off, then when I turn it on I get no picture on the screen until it loads into windows.

    The GPU is connected directly to the monitor using a DP cable and nothing more, I also don't have any kind of integrated GPU that can mess things off.

    However, when I connect the monitor using any other output, such as HDMI for example, there are no issues there, I can see my motherboard bios and the windows loading screen.

    I tried with a different DP cable, I tried with a different monitor and I also tried with a different GPU.
    What I found during those testings is:

    1 - Same GPU - Different monitor: same result, no picture on screen until windows loads to desktop
    2 - Same GPU - Different DP cable - Different monitor: same, no picture on screen until windows loads to desktop
    3 - Same GPU - Different DP cable - Same monitor: No luck, still no picture on the bios or during windows loading
    4 - Different GPU - Same DP cable - Same monitor: Success, we have a picture on the screen.

    So it's pretty clear where the issue is, and I also tried contacting ASUS with this same bug report, if it's even a bug, but it's definitely an issue within the GPU itself(most likely something small in the bios)

    I did not got a reasonable response from them other then "make sure you are running the latest official bios, and make sure to check our page regularly for future updates".

    The thing is, I'm already running the latest official GPU bios from ASUS for my GPU which was released a good 2 years ago and does absolutely nothing to solve this.

    I know, have zero reasons to actually do something about it because, you know... "give us more money by getting a new GPU" sort of mentality.

    So I'm willing to take this into my hands and do it myself if possible.
    The question is, can this actually be done with a simple bios edit/mod or it requires something more then just that?

    Thank You.

    I have the same thing but have onboard GPU and GTX 1070 the trick for me is to set the GTX 1070 in the bios as primary or in other words set it to Pci Express but you proberly allready thought of that

    This is not really an option for me since I don't have a onboard or onchip GPU

    Looks to be latest from what I can tell..
    Dump your bios here and I'll update the GOP driver of it(contains UEFI driver/legacy orom)

    Hey, no rush, man, appreciate the help.
    However, this has not helped as well after the update.
    Tried completely turning off the entire system for like 5-10mins, then tried switching from DP1.1 to 1.2 from the monitor OSD, none of which helped.
    The mobo bios and windows loading screen are still only visible trough HDMI and other inputs except DP

    Seems to be a compatibility issue that won't be fixed without a vbios or motherboard update(possibly even monitor firmware issue)

    One thing i would try is to make sure CSM is disabled(BIOS emulation instead of pure UEFI mode) or vice versa.

    Yes, I already tried that, CSM, UEFI, Legacy, it's all the same.
    I think a simple vbios update will solve it.
    I mean, if it works with a different GPU while everything else is the same, but not this one, it's pretty clear where the problem is.

    Not always, compatibility issues can manifest themselves in a lot of ways.

    Try emailing support for a later version, GL.

    Already did it prior to this thread.
    What the support gave me was simply "make sure to check on our page regularly for future updates"
    So far, you were way more helpful then this support guys at Asus.
    Anyways, I guess I just have to live with it.
