I would like to advise anyone who is considering getting a Predator monitor, to avoid it like the plague. You can read on this forum many reasons why and here is also mine:
Bought a new Predator xb271huabmiprz. First I noticed the strange sidebar appearing at random times (i.e. switching between apps) and after just 2 months the monitor suddenly went completely white. It would not display anything else - even in startup or bios - just a bright white image. So much about the quality of the product.
Secondly the customer support in Slovenia, EU is a joke. An absolute joke. The service center doesn't answer their phone, the official FB-Page does read my messages, but does not replay, contacts are hidden, links get you on Acer's main homepage. No temporary replacement monitor is provided.
The monitor is way over a month at the service station and they still claim that they are waiting for replacement parts. No one knows when the parts will arrive.
This was my first and last Acer purchase.
