The laptop I have is called Asus G751JM-BHI7T25. The LCD in it is called LG LP173WF4-SPD1 which is known to overclock to 100Hz easily. The problem is my laptop has NVIDIA Optimus enabled and the only way to create custom resolution is through intel driver which is completely broken. I researched around and it turns out old driver has no issues with intel custom resolution. LINK HERE: https://communities.intel.com/thread/45623 I already found the oldest driver for HD 4000 and downgraded my OS to Windows 7 for testing purposes. Now I need to find a way to add support for HD 4600 on the old HD 4000 driver (Ivy bridge and presumably has a working custom resolution mode).
