I got eh Acer XR34 it’s a 34in ultra wide 3440x1440 75hrz Freesync. They got a 100hrz g sync model the X34. I love it, going on two years now it’s been the best monitor I’ve used. The GF got the 2560x1080 version it works great for her doing school work or making patterns for her crafts.
I owned the acer x34 gsync version before. Now switching to lg34uc79. Its freesync 144hz. After going ultrawaide really cant switch back to other kind of monitor anymore. But anyway it usually depends on ppl choice. I will keep staying on ultrawide no matter what.
