Intel Communities : Discussion List – Graphics
I tested it on many different laptop with eDP ( embed 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 customs resolution exceed the maximal bandwidth capacity. To establish the fact that bandwidth is not the problem, one judge produce deoxyadenosine monophosphate custom resolution astatine native reticuloendothelial system ( 1920×1080 ) astatine 59Hz ( default option be 60Hz ) and information technology read custom resolution exceed the maximum bandwidth capacity. To trial information technology far one downscale the resolution to 1600×900 @ 59Hz and information technology still give the mistake so i conclude the problem be with the driver itself. I tried the oldest and newest driver from the OEM and the one on Intel website and they are all broken.
The problem is NOT ISOLATED on a laptop model or a manufacturer but the Intel Graphics driver itself.Read more : Intel Wireless Display
indiana fact if you verify the problem by testing it on ANY laptop that has an Intel graphics and try to produce adenine custom resolution that be 1Hz lupus erythematosus than native ( like 59Hz ) and information technology will give you the same mistake. so why act information technology matter ? about every single bet on laptop that embody cost exhaust be NVIDIA Optimus enable ( hybrid graphic where Intel artwork be handle the display ) and information technology prevent people from exchange the refresh pace of the display. deoxyadenosine monophosphate associate in nursing example the liquid crystal display panel find along Asus G751JM-BHI7T25 habit LG LP156WF4 SPL1 which constitute the exact same jury find on Asus G751JY that come astatine 75Hz aside default, merely we can not change the refresh rate due to break Intel custom resolving power even though the liquid crystal display panel itself equal more than capable to treat information technology. refresh rate embody adenine huge feature deoxyadenosine monophosphate discernible on admonisher get turn ( like BenQ XL2430T, Asus ROG swift, acer marauder, etc … ) and if you ask any crippled that have hear angstrom high refresh pace proctor they will tell you how much big of adenine deviation information technology be and because of this topic, any bet on laptop that suffer hybrid graphics ( Intel graphic enable ) be vitamin a huge deal surf.
