It ships fixed at 60Hz, all you have to do is go to the NVIDIA settings and go to the lower resolution section so you can change it to 144Hz. So far I'm really liking it and it seems like it's worth every penny. If anything changes I will update my review. UPDATE: 4/29/2021 The left speaker has stopped working for about 5 days. I tried to fix it but couldn't. So I contacted the seller and he responded immediately. The guy tried to fix the error over the phone but couldn't so he said he would call the factory at 5pm on Monday and contact us by phone. They called me at 4:00 p.m. and I was in the shower. I tried to contact him again for two days and left a voicemail but he never answered me! I ended up having to buy external speakers because I didn't know how long the return process would take between sending this monitor back and waiting for them to receive it before having to wait for a new one. Definitely a good monitor but not reliable speakers.
