Graphic card GTX 880M with integrated HD 4600 using Nvidia Optimus
Integrated monitor CMO1720 - CHIMEI INNOLUX N173HGE-L11 Overview - Panelook.com
Intel HD 4600 is used as default graphic card in OS, and whenever a 3D application is executed - Nvidia Optimus enables the secondary GPU (in this case GTX 880M).
This is working as intended.
As the integrated HD 4600 is the primary graphic card used in OS, the display settings enabled by this card will be the default display settings enabled inside 3D applications.
Meaning - You will not be able to select a display setting (resolution + refresh rate) inside a 3D application that is not enabled in OS. This is critical for you to understand before continuing reading.
Intel HD drivers also offer software to manage the display adapter - taking the control away from Nvidia panel. In this software there is the possibility to add a custom resolution.
However - adding any resolution will fail due to "The custom resolution exceeds the maximum bandwidth capacity". You will not be able to add any new custom resolutions at all, you may however overwrite existing ones.
Nvidia powered cards have the option to add custom resolutions + refreshrates that is not supported by the default monitor.
Doing so - a user can achieve higher refresh rates. This is critical for you to understand before continuing reading.
Currently I have no options to add a custom resolution + refreshrate with the Intel HD tool. Failing to do so leaves me with less display options to choose from inside 3D applications.
I need to be able to add custom resolutions and refreshrates that is not supported by default monitor (as you can do with the nvidia panel).
Is your software currently "working as intended"? Currently I am frustrated on the whole Nvidia Optimus setup as I am dependent on the Intel HD 4600 GPU.
If I where able to turn Optimus of and bypass the HD 4600 (like Alienware laptops can) I would be able to make changes in the Nvidia tool without problems - but as Intel HD suplies their own software to configure the GPU I am now in a position where I will not be able to enter a custom resolution for a higher refreshrate -> which is a show stopper for a gaming laptop.
Earlier feedback to clients experiencing this issue in the forum - your tech's have requested they send in their report generated from the software tool. They have then gotten the response that their display does not support anything above x HZ - thus the software is working as intended (more or less). This is wrong however - you should be able to add resolutions and refreshrates that is not supported by the monitor (as you can with the Nvidia tool) -> thus being able to "Clock" your monitor for extra performance. But currently I am not able to add anything - not even withing the scope of the supported values due to "The custom resolution exceeds the maximum bandwidth capacity".
What are your thoughts on the above?
Thank you for your time and help!
