Initially said Q2 2017 but some source said delayed indefinitely. Just get X34A as long you're getting the revision version 'A'.
X34A solved some old issue ( no swivel stand, bad QC ) but some issue remain ( bad OSD menu )

Mine got little bit if the room is dark and monitor is displaying black color output.

Looks more like IPG glow than bleed

Unless you game or use your computer in really dark room, light bleed was not obvious enough. Check again in your usual environment and setup.

Aiyok....then best to return. 

Sometimes price does play a factor that makes someone fussy about something. The monitor price ain't cheap. Paying a premium price and hopefully you won't encounter this type of problems.

Maybe because I did a lot of researched before deciding to made a purchased. I know what I have to deal with. 

I got a dead pixel on my X34A, gotta return mine to Paradigm for warranty.

True, that price can get 4 good FHD monitor already. Same, I did research ( actually research and hesitate for many many months ) so I know that we're paying for niche product.
Also, I'm happier because the time I bought, X34A just released and I was surprised to get a X34A instead of X34 

I bought a TV mount ( cheap but can hold 20kg ), can't use at all because X34 panel are too protruding and will fall face down. So yeah have to get real monitor mount/arm.
Wall mount don't think have any issue at all.

Not sure what you mean, but any mount ( wall / stand ) should fit. If I recall correctly, Acer have extra stuff for the external mount.
I use the 100x100 one.

Scared to "push". Nanti bocor how???

There is a few way to decrease the IPS glow on our monitor. Some easiest way like:
1/ Do manual preset to ur monitor, especially if u looking for color collaboration or the best monitor picture setting (U can find them in internet, there a lots of it)
2/ Readjust ur monitor high or angle or ur chair -  till it suitable to ur view & less IPS Glow
Since I'm doing a lots of sketch, picture editing & heavy rendering, I always put my monitor in manual preset which comfortable to me.
