My G257hu smidpx keeps powering on/off, wont keep lock with the signal for either DVI or HDMI (don't have display port to try). I also cannot access the OSD/Menu even when I do see an image. I press the menu bottons but no joy.  I think the monitor is at fault but I'd like to be certain before purchasing another. Any ideas / solutions are appreciated.
