Question about Acer Predator XB1 XB271HU

My question is whether this monitor has G-Sync. I am aware that this question has already been asked. When I enter the model number (from digitec xb1 xb271h), the acer homepage shows a model with a different product number (um.hx1ee.011) which has G-sync. If I enter the product number (um.hx1ee.a03 from digitec), I also get a model that has G-sync (xb1 xb271hu). I don't understand what kind of monitor this is from digitec... Greetings
