I had an IBM T221 IPS Display 3840x2400 running at 31 Hz for over one year without any problems before I upgraded to the Seiki 39' 4k at 30 Hz. I do not game. I use the monitor for work and web browsing mostly. I guess if you game, the 30 Hz refresh rate may bother some users. Do most Xbox 360 or PS3 games run at 30 frames per second, if so I would say mostly users are not bother by the low refresh rate.
I set my Seiki 39" sharpness to Zero which helped a lot with the burry text.
