    I don't have pixel acceleration.

    Yes you do, all recent monitors for the last several years have it. It's commonly listed in the settings as Standard, Faster, Fastest or Standard and Optimal/Enhanced. It's supposed to speed up pixel rate to change color and reduce ghosting, but can cause issues with VRR.

    Oh, response time, ok, will lower it or turn it off. Does turning this off significantly decrease performance?

    That helped, but if Firefox uses Hardware acceleration, youtube still goes to blank in full screen. Is there any fix for this?

    And what about HDMI 2.0 wich features to enable?

    Hardware acceleration is up and down going by posts on the AMD Reddit although I'm not sure if it's specific browsers, Youtube and it's various different codecs (VP8, VP9 and then AV1 though even with it enabled in Test Tube it's less commonly used.) or the drivers that broke something but from what it's looking like it could the higher resolution VP9 videos that are a problem, disabling HW acceleration and using the "Stats for Nerds" on Youtube's video should show what it's encoded with. :)

    Posts range from black screens, driver resets and even bluescreen and being forced to do a full system restart as a result so all in all it looks like AMD has some testing and work for resolving whatever is going on here.

    No, but enabling it can cause incompatibilities with other features. It's best to keep it on Standard settings, so you are compliant. Won't affect framerates or anything of the sort.

    Actually screen still goes blank in full screen, even if response time is disabled or at full ,medium or low.

    Did you check for firmware updates for your monitor? What monitor are you using?

    Hah, My friend have LG 27MP-68HM-P + RX 480 and he also have random black-out while gaming. We not fixed it but restraint this issue by changed cable for better quality ones. Seems to not related to Freesync or other option.

    Maybe it's not the same problem as your, but i think it's good to mention it.

    Im reading the internet and it seems everyone who has RX 580 has problem with Freesync, their monitor blacks out, so I think it is not problem in this app, but in 580 gpu.

    Actually issue is in drivers, Freesync in version 17.11.3 works ok, no flickering or black screen, so AMD needs to fix this, but probably wont, because this is told on their forum 100x times already and they didnt fixed it yet.

    Wierd thing happened, I installed driver v19.9.2 and Freesync works Ok, I cant find anything related to Freesync fix in release, so I dont know if driver is fixed or it is working now because I used driver v17.11.3 where Freesync works normally without black screens.

    AMD probably added some reader for source code of CRU Freesync and if it finds it it disables CRU enabled Freesync, that is why it is not working in versions later than 17.11.3. Someone should check this and fix it. But I dont know if Ihave neccesary skills, maybe I do but I have to find right program to do that job.
