KG271UAI'm still getting blackscreens with freesync turned on and still haven't been able to fix it.

I'm getting occasional black screens in fullscreen applications with freesync enabled. The blackscreen lasts for about a 1 to 3 seconds as far as i can tell its completely random and I'm unable to replicate it. I'm using the KG271UA monitor and a Vega 56 via display port. I've searched through many forums and found other people having the same issue but it would seem that any of the suggested solutions do not work. Including CRU freesync range tweaking, voltage swing and pre emphasis, disabling HDCP support, changing scaling mode, buying different cables (I've tried 3 maybe 4 different cables), using just the freesync monitor on its own, changing colour depth, DDUing several times and its even persisted through a windows 10 reinstall, I'm sure there's other stuff but I've been trying to fix it for so long now I've forgotten a lot. Is the only thing i could hope for a driver update from acer for this obscure monitor model?

Have you tried disabling overdriver, quick start mode and refresh rate to see if the problem remains?

I am unable to select overdrive at all, the gaming section on the monitor setting only lets me change the aim point setting not over drive or mprt.

Check these functions:

Thats what my menu looks like atm. i cant touch the over option though, so its stuck on normal.

Commodore_1995#

OK! But have you checked if the problem still occurs by disabling the other functions?

Invecitve

Nope that did nothing,half the options in the monitor menu i cant change anyway. Nothing i do fixes this issue. I have had the issue for almost a year and i have tried countless suggestions and methods.

Does this problem only occur when it is at 144hz? See also this video in Portuguese, but with the English subtitles:

No option for english subs.

You must click on "translate automatically" and select the language "English". The second answer of this link also has a possible solution!

I'm not getting any useful info from that video, i don't even know if he has the same issue as me. With freesync turned on it seems that when my fps is 100+ my screen will randomly go black for 2-3 seconds and then come back on, there's no crash or anything the screen just turns black and there's no other side affects. I have seen countless other post about people having the same issue and there doesn't seem to be a proper fix, some people have said that changing the colour depth fixes it but not only does that not fix it for me but the colour turns to **** if you do that. There's also post about CRU and voltage swing those don't work either. i have also brought two new amazon basic display port cables and noticed no difference between them and the other DP cables i have tried. When i got the monitor i thought that HMDI solved the issue but i don't even think freesync over hdmi works for me at all so the only reason i went with hdmi was that freesync didn't get enabled in the first place.

Can you enter the type of panel your monitor uses using hwinfo64? Example:

I think that way we could find something more concrete!

OK! Verify that the correct monitor idhardware appears here:

It just says generic PnP https://i.imgur.com/KKgY3lP.png i have already manually installed the drivers before and i dont think theres actually a kg271ua driver just a non A variant.

Commodore_1995#

Please click on idhardware and not device description.

https://i.imgur.com/Wu4BANB.png says the same thing that hwinfo calls it "ACR0623"

I was looking on google and found this information, see:

What about it?

Commodore_1995#

I'm trying to find something related to free-sync, using the panel name M270DTN01.3QE on google. Perhaps AUO support can provide some kind of information?
