The problem is NOT ISOLATED on a laptop model or a manufacturer but the Intel Graphics driver itself. I tried the oldest and newest driver from the OEM and the one on Intel website and they are all broken. To test it further I downscale the resolution to 1600x900 59Hz and it still gives the error so I conclude the problem is with the driver itself. To establish the fact that bandwidth is not the problem, I tried creating a custom resolution at native res (1920x1080) at 59Hz (default is 60Hz) and it says custom resolution exceeds the maximum bandwidth capacity. I tested it on many different laptop with eDP (embedded displayport) like Alienware 17, Asus G751JM, Asus Q551LN, Lenovo Y50-70, Razer Blade 14, MSI GT60 Dominator Pro, and Gigabyte P34 and they all say custom resolution exceeds the maximum bandwidth capacity. No matter what setting you put into it, it will always custom resolution exceeds the maximum bandwidth capacity. The problem is Intel Graphics driver for HD 4600 (and presumably others too) have a broken custom resolution for Built in LCD. I emailed Intel Customer Support Service and they refer me to this forum because the agent say it will have the correct exposure to intel engineering department.
