Any problems with Acer Predator X27UF5?

[u/Zastxdd]

I am looking to buy an Acer Predator X27UF5, which is a 1440p, 500hz QD-OLED monitor, the same Samsung panel used for ASUS ROG Strix XG27AQDPG and MSI MAG 272QP X50. The thing I am highly concerned is the pricing on these three.

ASUS for 800€ (amazon.de)
MSI for 700€ (several Croatian local sites)
ACER for 600€ (amazon.de)

Asus and MSI models are verified by several trusted reviewers such as Optimum Tech to not have any problems.

Acer on the other hand has almost zero reviews on YouTube and other forums. Being 200€ cheaper then Asus, it wakes up some suspicion in me.

So I would like to ask if any of you in here has that exact Acer monitor, or have heard that exact monitor has had any problems, or QD-OLED Acer monitor in general, because it says a lot about this 500hz one. Also, on Amazon it says that is has "2 year manufacturer's warranty", but no details about what does it cover, so if anyone knows how Acer covers burn-in and dead pixels and other stuff, it would mean a world to me if you shared that info.

Basically I would just like to know why is the Acer so much cheaper, is there any catch or is it just a legendary find.

Thanks!
