Try the same setup but with VGA.

i figured something out! the issue it is triggered when i shut down and power on again the monitor. and only when the amd drivers are loaded (everything is fine in the bios and when i uninstall the drivers) i can solve it rebooting the pc. changing the hdmi cable or disconnecting it wont solve it.
another thing, maybe important: the windows hardware troubleshooter gives me the error 0x8000FFFF only when amd drivers are installed. i tried 4 different versions of the drivers (one older , 2 beta and the current stable) and it is always the same. (monitor blinking after power off and on, and windows troubleshoot error)
if i use the second hdmi port on the gpu while the monitor is blinking, the blinking disappears until i power off and on again the monitor. then i can plug in any of the 2 ports and the blinking occours until reboot (or driver uninstallation)
could it be windows 10 fault?
i need to buy an adapter for vga input, but i have an older machine at my parents house. when i'm able to grab it i'll try moving gpu and monitor to that system.

Drivers are the responsibility of the makers. I know folk want to blame Microsoft but Microsoft has yet to accept the responsibility for driver creation.
AMD/ATI is well know for driver issues.
All that aside I do encounter folk that forget the usual post Windows install work. For me for a new build it's BIOS update, maybe a BIOS load defaults, reinstall Windows then motherboard drivers, audio, video, LAN, WiFi and apps that the machine requires for control of WiFi and such.
thanks, i'm just trying to find the root of the problem and i was "blaming" ms because there seemed to be a connection with drivers installed+failure on troubleshoot. also because on another machine with the same windows version and the same drivers (different gpu tho) there is no such problem. so i was thinking that maybe something went wrong with an update or system files. i don't know if it could be the case.
also, what you described is my exact workflow. i'm not an expert but i biult my pc by myself and i follow these steps.
the most important thing to me is to find out what is the problem and fix it if possibile, but most of all, find out if it is a software or hardware problem so i can rma while i'm under the warranty period (and because i'm curios to know that's causing it ![]()
I am a bit too seasoned on how to install not only Windows (almost every version) but also the post install work. If I suspect hardware we swap out the suspect part. In some cases we can test our assumption by putting the card in another PC.
But I didn't read exactly what steps you did pre and post Windows install.
I continue to encounter folk deathly afraid of the BIOS update. And this is the time to get that current. Not only that but this is where the Spectre and Meltdown is usually patched.
the patch just released for my motherboard and i will apply the firmware update as soon as i can when i'll be back home. i don't know if this could be the reason why something is wrong, but i had another radeon card before. i've always uninstalled drivers with ddu in safe mode or with the ati utility. i'm formatting anyway. and also trying on my old pc with the monitor. i just hope the power supply is enough to power the card.
i also want to try disabling fast boot and check some others power management in the bios. i just really hope it is not a gpu problem because i can't rma at the time (amazon.it does not have cards in stock right now...) that's what i am afraid of.
When I install Windows (almost every version after Windows ME, we never format the drive as this will trip up the Windows installer.
As to the GPU https://ark.intel.com/products/97150/Intel-Core-i5-7600-Processor-6M-Cache-up-to-4_10-GHz shows you have a CPU with graphics so you must test without the GPU. This gives you a chance to be sure the motherboard and CPU drivers are correct as well.
well, i didn't know about this. i'm learning a lot of things investigating on this problem. so this is it?

so if no errors occour while i test the onboard gpu, i'll be sure that those are fine. still, i will not need radeon drivers (the only thing triggering the issue), so i'm already pretty sure i won't have problems (?) i'm trying to understand. and thanks again for helping
Here when I want a clean install I just delete the partitions on the target drive and then boot and install Windows. I let Windows take care of the partition and formatting. If we format before install, then we are installing a very old Windows like Windows, 1 through Windows ME.
oh perfect, that's what I meant with "formatting" I've always done it like this, letting the installer take care of that part. I should have said "reinstall" anyway, I hope to fix at least the hardware troubleshooting error. the old pc is ready. maybe tomorrow evening I'll be able to try
i want to update. maybe you o someone else can understand better what-s happening because i have no idea.
i did a fresh windows install and the issue is still there. i tried connecting the monitor to my old machine with a sapphire radeon r7 260x, and the same drivers, and no issue... sadly the old pc case is too small and i can't test the gpu on it.
but I just put the r7 260x on the new machine (old drivers form windows update 17.1.1 jan 2017) and no issues. put againg the rx580 and for some reasont it started working ok.. kinda...
if i shut down the monitor, sometimes i hear the windows sound of a device being unplugged... powering on again it starts blinking. powering off and on again it goes back to normal. i cannot update the drivers from the radeon software that windows installs, but if i uninstall and install another driver the issue is always there... ***? i'll also try filling a report to amd. i don't know if i'll be listened...
also... if I switch windows user it starts again. powering off and on the monitor solves it now...
If so it's the card at issue or a procedural one.
When I setup a new PC it gets the latest BIOS then Windows (or another OS) then drivers in the order of motherboard, audio, video, then LAN, WiFi and the rest. Depending on the PC it may get apps to control the machine features.
I find a lot of new builders that resist the BIOS update. NOW is the time while it's in warranty. Even so in over 2 decades I've yet to lose a board on update.
thanks for the reply. i forgot to say that i updated the uefi before reinstalling windows. and for some reason the windows troubleshooter started working again. still, e get all these issues. also this. the monitor osd sometimes when i boot shows me this screen (i always ise the supported 75hz) 
HDMI may be locked to 60. Long reasons why.
