AW3225QF, brightness setting not preserved and random black screen when switching smart HDR mode

Hi everyone,

I recently got my hand on a AW3225QF monitor and so far I'm in love with it.
However, there are a few issues that I'm unsure if anyone else has experienced with this monitor, since I couldn't find any information on the Internet and this forum. I just want to be sure that my monitor is not defect and these issues could possibly be software issue.

1.  The first issue I have is my brightness setting is not preserved whenever I turn my monitor off and on again, when I enable Window HDR and turn it off later on. Whenever I do those things, my monitor brightness ignores my setting (I set the brightness to 60%) and just go full brightness, look to me like the default 75% brightness. If I open the OSD, go to Brightness and adjust, the brightness immediately changes back to the value I change to.
2. Whenever I switch smart HDR mode between TrueBlack HDR400 or HDR Peak 1000, or turning Dolby Vision on or off, if I have some HDR content playing in the background (like a game, Netflix, YouTube livestream, etc.), the monitor sometimes just goes completely black and says it can't detect signal from the port I'm connecting to (I'm using the included HDMI cable to my RTX 4080). I can still hear the audio going while the monitor is in that state. After some randomy amount of times (usually 5 minutes), the monitor turns back on again with whatever content that was playing crashed. It seems to me that for some reason the monitor crashes my GPU, and after a while my GPU driver resets and recovers (which explains why whatever HDR content I was playing just crashed)

Would love to hear if anyone else experiences these issues and if someone has a solution. Thank you in advance.
