I'm a happy owner of the 29UM68 for about 2+ months.

The awesomeness and issues of Ultrawide aside.

I love this monitor to death tbh.

Just some general opinions, nothing in-depth.

-IPS is awesome, viewing angles are fine.
-Freesync @ 40-75hz is a huge plus for an ultrawide at this price.
-Color reproduction wise, I'm no professional but it's fine by me. I did tune the white balance to own liking though. I bet you can find info on this elsewhere.
-Built-in speaker....?  IMO, it's not too bad but still it's a freaking monitor built-in speaker.
-Stand is kinda wobbly (but not the worst I've seen) and no height adjustment, nothing compares to the Dell Ultrasharp stands, those are the best I've used. I replaced it with another monitor arm anyway.
-OCD control is one of the best.
-Anti-glare coating is not too aggressive, just nice.
-The bezel is a bit thick (I was accustomed to the U2414H bezels, so yeah), the bezels in the picture are misleading. Don't trust it.

Judging from the specs this appears to use the same panel from Samsung's CF791:

Also the same Samsung panel is also used in the MSI MAG341CQ:

However, a monitor that uses the same panel as another monitor does not always mean they will perform identically

I don't get the correlation of your comment with kyLL's  , it makes no sense at all

And btw, drop it to <rm4k and you'll conquer the market.
