Well I made an account just for this. I've been following this monitor closely and it's very exciting. I'm probably too new a user to post links, but there are a few Youtube videos where the Acer rep at computex explicitly says "it's 100hz." Also, the Asus competing version will offer "at least 75hz" according to their rep, so it sounds like Asus is trying for 100hz too.
Makes sense, the DP1.2 bandwidth is there. I posted this at another forum after doing the math:
To determine the LCD Data Rate I take the Pixels for one frame and multiply this value with the refresh rate. So I get e.g. 3440x1440x100Hz = 495,360,000 Pixels/s. To get the Mbit/s value, we multiply the Pixel/s with the size of one Pixel. So 495,360,000 Pixel/s x 32 Bit/Pixel = 15,851,520,000 bit/s, or roughly 15.85Gbit/s. Displayport 1.2 can do 17.28Gbit/s, so theoretically you could pass 3440x1440 at 100hz with 32bit color over one displayport cable. Using that same math, 4K (3840x2160) at 60hz is 15.93Gbit/s and we know that works.
Top theoretical refresh limit at 3440x1440p with a 32 bit pixel depth would be 109hz. So yes, this panel could do 100hz and have a little room to spare. Whether they can get the IPS panel to do that is another story, but there are IPS panels at 144hz, so that's possible too. This would be the first time I'm aware that Acer, Asus, or anyone put all that together.
On a side note, I'm really enjoying the forums and the tech videos on this site. Quickly becoming one of my regular visiting places.
