Will BenQ be releasing any larger 4k IPS monitors with freesync this year?
I am not aware of any plans at the moment. The problem would be that the refresh rate would be very limited (75Hz max due to data bottlenecks) and the response time would be, at best, 4 ms. It would make it a very limited gaming monitor, so the market for it would be very small. Here in a year or so you should start seeing decent gaming monitors in the 4k resolution.
