Hi (new to the forum here)
I just recently bought a Samsung Ultra-wide monitor 34" (S34E790C) and I'm only getting 30hz refresh rate with my computer (Asus G74sx Laptop) using the HDMI cord they provided in the box. Everything is choppy/laggy (ie. Opening/closing windows, typing and moving the mouse). I didn't know HDMI only supports 30hz on this monitor. It also has a display port, but I'm not sure if my graphics card (NVIDIA GeForce GTX 560) can support it. My computer only has VGA and HDMI outputs. How can I increase the refresh rate or is there a limiting factor with the graphics card?
