Hi Dunking Donut,
May you help to record a video of the issue?
hi, i can not record a video of the issue, it happens randomly and at different times.
i see you've also asked a fellow customer here https://rog.asus.com/forum/showthread.php?123341-Asus-PG329Q-HDR-mode-sudden-decrease-in-brightness&...
the issue has been reported several times on many forums, there are a couple of them here including me https://linustechtips.com/topic/1266691-hdr-issues-on-a-asus-rog-swift-pg329q-update/page/2/?tab=com...
i'm sure you guys can replecate the issue with enough testing, but like all well paying customers for this monitor, it's REALLY annoying when playing games, even when working in photoshop. we all would like to get it fixed through firmware update possibly.
it's a good monitor don't get me wrong, but having it turned on for 30 - 40 minutes and having it dim itself by 25% is a real turn off.
i'm not willing to send it back for RMA, i need it for work too, so hoping for a different fix
