every electronic component makes some sort of noise (EMI)
if your current cable acts as antenna, ull get issues, either get some clap-on ferrites/decent high quality cables with ferrites to reduce that noise or dont use that m2 :)

So after more testing, I installed Kubuntu on my M.2 Samsung Evo 960 that Windows was on and ran into problems as well.  So it seems to be a problem with the M.2 sata and the board. Seems whatever os is on the M.2 has the issue.  I am emailed my results to Support.]]> Thu, 28 Jun 2018 23:38:48 +0000 https://forum.asrock.com/forum_posts.asp?TID=9026&PID=53105&title=screen-flashing-to-black-over-29hz#53105 <![CDATA[Screen Flashing to black over 29hz : Running Kubuntu Linux 18.04 from...]]> https://forum.asrock.com/forum_posts.asp?TID=9026&PID=53076&title=screen-flashing-to-black-over-29hz#53076 Author: gwilly7

Running Kubuntu Linux 18.04 from a USB stick for 3 hours now set at 4k@60hz with no issues.  Must be some kind of windows driver issue.]]> Thu, 28 Jun 2018 02:59:06 +0000 https://forum.asrock.com/forum_posts.asp?TID=9026&PID=53076&title=screen-flashing-to-black-over-29hz#53076 <![CDATA[Screen Flashing to black over 29hz : Thanks, I will look into this....]]> https://forum.asrock.com/forum_posts.asp?TID=9026&PID=53063&title=screen-flashing-to-black-over-29hz#53063 Author: gwilly7

Thanks, I will look into this.  Tested a little more with Libreelec today and had no issues using 4k@60 resolution, so seems it might just be a Windows issue.  I am also going to try and install Ubuntu today to see how that goes.]]> Wed, 27 Jun 2018 23:44:51 +0000 https://forum.asrock.com/forum_posts.asp?TID=9026&PID=53063&title=screen-flashing-to-black-over-29hz#53063 <![CDATA[Screen Flashing to black over 29hz : add ferrite chokes at each end...]]> https://forum.asrock.com/forum_posts.asp?TID=9026&PID=53058&title=screen-flashing-to-black-over-29hz#53058 Author: kerberos_20

I just upgraded my board to a Fatal1ty X470 Gaming-ITX/ac with a Ryzen 2400G.  I am running Windows 10 with the newest AMD Chipset and Graphics drivers.  I am going through a Dennon X2300w to a Vizio P65-C1.  If I set  my resolution higher than 3840X2160p @ 29hz my screen will flash black for a few seconds every minute or two. I am on Bios 1.11A I have even tried reinstalling Windows.  My previous motherboard did not have issues and ASUS B350M-E and I also have an Asrock J4205-itx connected through the receiver that does 4k@60hz without issue.

Any Ideas before I ship it back to Newegg?
