Hey, guys! So I have GL2450, and the screen is flickering ever since I bought it. I thought it was normal at first, but it's certainly not, and it's very annoying. I have tried setting frequency to 75 hz, but then everything stretches out of the screen (but it actually reduces the flickering dramatically). The monitor is connected through a dvi adapter. Help me please, I really can't afford buying a new monitor right now.
