Acer Predator XB252Q Review
30 January 2018
+ Build quality, materials used
+ Highly adjustable stand with barely any wobble
+ Discreet bezel, sleek design
+ Boots up instantly
+ Extremely bright (400 nits)
+ Comprehensive OD settings
- Bright green stuck pixel
- Backlight bleed/clouding across the centre of the screen has gotten increasingly worse each day
- Mediocre contrast/black levels, but this is to be expected with a TN panel
- The jump from 120hz/144hz to 240hz is negligible and not worth the substantial increase in GPU power/temps when gaming
- Now for the big one, G-sync. I have been desperate to try a G-sync monitor for years now after hearing what a mind blowing and revolutionary piece of technology it is. However, after thoroughly testing it out now for several days I honestly cannot see what all the fuss is about. It is meant to make the image feel "smooth" by eliminating screen tear while also preventing the stutter caused by duplicate frames as a result of v-sync. But I found the difference so incredibly subtle that I simply cannot justify the absurd cost for its inclusion. Personally I experienced almost identical results by just enabling v-sync and triple buffering in the Nvidia control panel.
- Additionally when G-sync is enabled on this monitor it can cause some severe flickering and pixel inversion. This results in the appearance of ugly vertical lines whenever something moves on screen (most noticeable when gaming or watching videos). I believe most people don't tend to notice this side effect but if you are very sensitive to this like I am I would avoid this monitor as it often leads to feelings of nausea.
- Although the aforementioned vertical lines are most prevalent with G-sync enabled they are still evident with it turned off. The lines are most apparent at lower refresh rates (60hz in particular) however they are still evident at 120hz/144hz/240hz. I have included some photos I took to show you what it looks like.
In conclusion I am disappointed with this monitor. On the one hand the build quality, design, brightness, ease of use and range of options are fantastic. But on the other hand there are some severe issues when it comes to the screen itself. The poor backlight bleed and stuck pixel I encountered are extremely annoying but they are an unfortunate reality with all digital displays regardless of the make, type, cost, etc. However the main issues listed above are what prevent me from recommending this particular monitor. In my opinion the extra cost for 240hz and G-sync is absolutely not worth it and the unsightly appearance of vertical lines caused by pixel inversion compromises the entire image. Amazon is currently selling this monitor for £200 less than the RRP (£550) but even with that discount £350 is A LOT of money to ask for with the severity of the issues I experienced.
