Asus ROG swift PG35VQ - 200hz HDR UW - basically ticks all the boxes with Acer and no doubt other manufacturers bringing new monitors to market based on this panel. It was supposed to launch earlier this year but panel production issues have delayed to supposedly Q1 this year.
LG have new stuff they'll be displaying as well.
Whilst I don't expect these to be cheap I'm hoping it brings down prices on the current top end monitors.
I reckon it will be more like Q3 before they are actually available.
