AW3423DW in my case, got it asap after release (3 months of waiting) and still going strong. I work on it way more than I play games or consume media. I didn't even bother with hiding task bar, though I use dark mode in windows and apps (not in all of them, though). No burnout at all, no issues with fonts clarity when working, superb for gaming and gladly they also let one upgrade firmware these days after months of claiming that will never be possible because of gsync module.
if this ever dies, I'll just get another (newer gen) of such monitor. Not going back to IPS, as low latency, no blur in movement and HDR in media consumption or gaming are just way too good to give up on them.
Now, it's not perfect, gsync module fan makes noise now and then and it's impossible to remove Alienware app that Windows installs automatically (short of blocking all updates). Standard blocking of KB or drivers installation do not do anything.
