Here with my personal thoughts on the XB270HU.
For years I had various high end IPS monitors that cost £700 (BenQ fp241w) that at the time I thought were the bees knees, and they were at the time. This mini reviews conclusions are are focused on 27" 1440p monitors (mainly between the Asus Swift and Acer Predator).
My last monitor I had before I entered the realm of >60Hz monitors was a Crossover 27" and it was good, apart from the glossy screen and heavy uncalibrated colours (which was easily remedied with a colour calibrator).
Then it all changed, I got a Asus Rog Swift and I was blown away by the response and lack of a blurry image and was even playing games better (best chassis I have ever seen on a monitor too), things were more point-and-shoot-and-shoot-straight. I was in bliss before I started to notice the overdrive noise (goes by various descriptions). I went through a few of them (3 in total) and I could not get used to it. Near that time I had noticed news of the XB27HU and was eagerly awaiting it, but was still many many months away until release.
I then moved over to a QNIX 27" PLS Evolution II, and, for the price when overclocked is pretty damn cool - however there was the usual slight blurriness that comes with the standard IPS type technologies. I was happy to put up with it and even got used to it within a few days. The frame response was the most important thing it seemed, to me (I was running at 96Hz).
Yesterday my XB27HU arrived, I am pleased with the build quality (it isn't styled futuristic like the Asus Rog Swift) and I am not a fan on piano black. However the bezel is thin and I am using my own VESA stand that can rise higher than the stock XB27HU one and the base not curved like the XB27HU is.
The menus are slightly fiddly although all I did was tinker and then leave it alone. I found the brightness of about 60% is good, while the 100% is far too bright, so plenty of adjustment there. I used a ColorMonki to calibrate the colours as the monitors was slightly too cool.
I have fired up a few games (Crysis 3, Far Cry 3/4, GTA) and the pixel response times for truly are the best I have ever for an IPS panel.
How fast is it? I would say not quite as fast as the Asus Rog Swift, but close enough and close enough to see this is no ordinary IPS monitor!
The pros are:
*You are getting an IPS Panel with close to TN speeds.
*Obviously the 1440p/27"/144Hz specifications
*The colours & contrast blows the Asus right out of the water.
*So far no dead/stuck pixels (for my monitor anyway)
Cons:
*In a very dark room there is some Backlight bleed, some due to chassis/panel pressure. The Asus Rog also had this (but doesn't bother me - Stuck/Dead pixels do). During normal use Backlight bleed is undetectable.
As for GSYNC, IMHO only counts if you are running lower FPS because your GPU cannot keep up (I am running dual 980's and always get >90 in most games). GSYNC does shine in side scrolling games like Starcraft etc as apparent jittery motion is VERY noticeable - again personal findings. So overall, most of these monitors are overpriced because of the GSYNC module, but it is nice to know it is there if i need it.
To sum it up, would I have the Asus or the Acer if I had to do it all again?
My answer obviously is the Acer - every time. The IPS quality is fantastic and overall makes up for the slightly slower pixel response times WITHOUT overshoot distortion like the Asus has (and for which ultimately killed it for me and why I had an overclocked QNIX instead.)
Is it worth the price (I paid a bit less as I imported it)? I would say that unfortunately you have to spend this money to get what as pure bliss, smooth quick frames (IPS/144Hz/1440p/4ms - lots of 4 in there
). I would prefer these types of monitors to be around 450 Pounds, but that is dreaming.
Overall it is a personal choice but I have been through a monitor hell trying to get the best overall with the least compromises, for now the Acer XB270HU is it for me. (Keep any eye out for the 3440x1440p 144Hz IPS monitors
)
