      My notebook internal monitor supports a vertical refresh range between 40 and 120 hz.

      Even if the monitor inf has all definitions and all frequencies, the intel driver displays only frequecies in the range 40-100.



      If i try to add a custom resolution, I always get the message that the maximum bandwidth has been exceed and that's totally crazy because this happens even if I try to add 1920x1080 @ 55 Hz (or 65 Hz).


      I am using the latest drivers  

      The graphic card is an Intel HD 630 on a kaby lake cpu.

      Isn't it time that you fix this??



      In control panel >> display >> custom resolutions >> help

      there is a mention to an advanced mode.

      How to enable it?

            I checked both of those reports and there is nothing useful to this specific problem.


            Just take a recent laptop with intel/nvidia combo in prime.

            Then try to add a custom resolution and you will have the same problem.


            By the way, I could add custom resolutions but only using a third party utility named CRU (custom resolution utility)

            Using that I added many custom resolutions and refresh rates and they all work.


            Moreover, if you just do a google search for "intel custom maximum bandwidth exceeded" you will find many results (first of which is this very forum).

              Anyway, I wasn't seeking for help to set a custom resolution (I succeeded manually) but just to inform you that the "add custom resolution" feature in the intel graphics settings application is totally broken on laptops.

                  You can see similar reports here unknown

                  Custom resolution > maximum bandwidth


                  and here



                  and in many other google results.


                  Also, my monitor edid advertises only 59 Hz and 60 Hz but supports between 20 Hz and 110 Hz vertical refresh on any resolution up to 1920x1080.


                  Adding a CUSTOM resolution should just be that! Adding non standard resolutions and see if the monitor supports them.

                  And this is what happens in NVIDIA control panel.

                  Unfortunately my intel/nvidia combo is PRIME so any change in resolution is not enable on nvidia card but on the intel card.

                  That's because on PRIME, nvidia "layers" over the intel card and the intel card is "in charge" for the basic things like resolution, refresh, etc etc
