I believe it is marketed as a gaming monitor but maybe not I saw it on amazon and started looking into it a little further.
It doesn't really make since for them to make a cheap 1080p 144hz monitor since that space is already dominated by BenQ and Asus, established names for gaming monitors. But with 1440p G-Sync 144hz there really aren't many players other than Asus and Acer, allowing them some space to carve out a bit of market for themselves.
