Does anyone have Fedora 23 working with a 4K monitor? Last week I got an Asus PB287Q monitor, but got bit by the "hardware loses signal when monitor goes into sleep" issue. I'm returning that monitor and would like to get another one, but am hoping to find a good success story. I'm running Fedora 23 with a GeForce 750 Ti card using the NVidia drivers. Does anyone have a working 4K setup with this or similar hardware?

Thanks,
