Looking for secondary monitor

[Abula]

Hi,

Im looking for some suggestions or opinions into what monitor would work better for a secondary, my main is a Acer XB321HK that im pretty happy, but im looking for a secondary monitor to display Mumble, HWmonitor, GPUz, Twitch panel, among other things, but wont be used gaming, its mainly for monitoring extra things while gaming.

I would like it to have or be,

- Good viewing angles, it wont be seen straight on but will be placed to the side of the Acer.
- Good color quality, i would prefer IPS panel, but open to VA and PLS.
- Size not bigger than 22'', will be used on portrait, so i dont want to have it to high.
- Would like to have Display port, but not mandatory.
- Refresh rate is fine 60hz
- VESA mount is a must, as i plan to hard mount it to the wall.
- Resolution, ideally 1920x1080, but open to 1600x900, i want it to be easy to read while im gaming with the Acer.


The monitors that i im considering are,


Samsung 21.5" Screen LCD Monitor (S22E650D)
Vesa 100x100 compatible, 1920x1080, PLS panel, displayport

Asus C422AQ 21.5" Screen LED-Lit Monitor
Vesa 100x100 compatible, 1920x1080, IPS panel, displayport

Viewsonic VG2239SMH-A 22-Inch Screen LED-Lit Monitor
Vesa 100x100 compatible, 1920x1080, SVA panel, displayport


Having owned a Samsung SA850 the PSLS panel was fine with me, and like the laid back style of the monitor, but its the most expensive, and not sure if it will be better than Asus IPS or the Viewsonic SVA, so looking for any opinions into what you suggest would be the better pick or if you have any other monitors that i should consider.

Thanks for your time,
