It’s the Gigabyte M32U. It’s a good monitor, like I said it’s just me, some people just seem to not profit from it. It is a bit better than 60 Hz, but it’s not the big difference to me compared to 60.
I followed and tried many things from here: pcmonitors.info/reviews/gigabyte-m32u/, including overdrive. I bought a new cable, tinkered with the settings, both monitor and driver, it’s just me :) maybe it has to do with age!
