I recently purchased an MSI 322URX - this was based on largely glowing reviews, and I agree with them for the most part, the monitor has a beautiful display, no dead pixels and when it's displaying picture it's been great. Previous monitor was a first gen Alienware aw3423dw
But golly - do not buy one if you fit into any of these categories:
Use multiple computers - is there is no output on the connection the monitor is set to, you cannot change it to look at the other ones... IE, if you were using it on displayport, and that PC is asleep and want to use the HDMI ? you need to turn on the computer in display port, so that it gets a picture, where you can then adjust it.
Out of the box there were constantly display errors, luckily the firmware updates seem to have resolved it.
The KVM is super painful to use, because of the first issue, so I gave up on that and use a usb switcher instead.
This is my own fault, but i accidentally tapped the edge of the screen with a usb cable, which i've done on other monitors before, and it gauged a chip out of the display coating, which i've never seen happen before. I don't blame MSI for this, but it seems like they may be using a crappier coating as well that doesn't stand up to day to day stuff. Be super careful with your MSI Oled guys!
Long story short, I've been using Dell/Alienware monitors mostly, and while not without their faults (my aw3423dw was replaced several times for dead pixels, fan issues etc), they do get basic functionality right. I write this mostly so that if you are searching for an MSI monitor and your use case isn't, 1 monitor, 1 PC, then you might want to look at the competition.
Second, would be nice if reviewers in the tech space looked at anything out than raw specs and output, usability is rarely commented on and living with something for years is a big part of the purchase. I've had this for a week and already getting the shits.
