After lots of reading and price comparison I have narrowed my search down to a few 32" 1440p freesync monitors from Microcenter. I prefer to stick with Microcenter because I want to purchase it from a brick and mortar store and we all know that the Best Buy is only good when they price match but their sales associates suck...
And I want to stick with 32" because it is roughly the same width as my 29" ultrawide and I'm used to this size for over 5 years now.
I am really leaning towards the MSI which is $350 after rebate. The MSI seems to be slightly better overall compared to the LG.
MSI Optix MAG321CQR:
DCI-P3 92%, sRGB 122%,
Gaming OSD App (control the monitor exclusively from the Windows based application)
Mystic light (programmable LED lighting on the back)
Blue light reduction (which would seem to mess with the color calibration?)
1ms response time (MPRT)
Tilt and height adjustment
Dynamic action sync (is this a form of response time adjustment?) I have trouble with this on my 29" ultrawide and lowering the response time results in severe ghosting.
Black stabilizer (which would alter black level, again messing with calibration)
Crosshair (would be annoying to have it on the screen when in a game's menu)
1ms Motion Blur Reduction
So basically what I gather from these two monitors is that the MSI has a slightly better color gamut (reviews give the LG a mediocre rating for color accuracy) And the LG is slightly better for gaming due to the 1ms motion blur reduction.
EDIT: it looks like the MSI has a 1ms response time as well, probably utilizing a strobing backlight as well.
The cost of these monitors is
MSI $399 ($350 AR)
It still looks like the MSI edges slightly ahead for all these areas. I have almost forgot to mention I have an MSI RX 480 8Gb "reference" graphics card and Intel i7 4790K CPU w. 8Gb RAM if that gives you an idea if 1440p is a good upgrade from 2560x1080p.
