Changing monitors gpu usage

Hello, i have 144hz monitor, but i'm having laptop. Problem ofc is that i can't use dual link cables, cuz i don't have ports for them on my laptop. i read that i can use 1.4b+ hdmi cables for it to get atleast 120hz. 

 

and problem for me is that i tryed to make custom resoliton/hz setup. i can make only up to 80hz, if i try to make it higher then my monitor shows that it is out of range (bridwight (don't know how to spell it :( )  can't handle it) but my hdmi 2.0 should be able to get to 120hz. 

 

i think the problem here is that my monitor is working on my integrated intel hd graphics 4600, not my gtx 850m. i have tryed to switch off my integrated graphics, but then my monitor didn't work at all, only my laptop's screen was working. 

 

can anybody tell me how can i make my monitor work on my nvidia gpu, not intel?? or if anyone else know how i could make it work in other way then you can sure help me. 

 

any information is welcome. :)

 

update: i can get 120hz with 1280 x 720 resolution, but ofc i want to do 1920x1080. when i'm trying to make 1920x1080 and above 60hz resolution it says that my bandwidht isn't capable of that. that is with dvi-dl to hdmi adapter, with only hdmi cable i was able to get 1920x1080 80 hz.

My friend, you have the exact same problem I have. 73hz for me.

-EDIT-

I tried using an adapter but It only could reach 70hz until saying that the cable is malfunctioning.

 

i have searched so much on google about this problem and i see many people have this problem, but few of them have gotten those 120hz, but i can't find how.

It is probably with the limitations of the hdmi jack on the display. Mine only can reach 73hz. Some other monitors can reach 120hz. Converting the signal does no good either, that might be cause of the quality of the adapter since mine was 2 bucks.

ye i know that, but do i need that adapter from dvi-dl to hdmi to try to get those 120hz?

 

Yes, you see, the components inside the display that accepts the signals are separate. There is no need for the vga connection to have bandwidth equivalent of 144hz 1080p inside the board.

I suspect that the inner components are all geared for you to use the DVI-DL option. And HDMI as a backup.

There is a ton of confusion here, not helped by people giving advice without knowing stuff...

 

First thing, cables do not have revisions. There are no HDMI 1.4b cables or HDMI 1.4a cables. There are only HDMI cables. The capabilities depend on the maximum the laptop can send over HDMI and the maximum the display can receive over HDMI, nothing else. Whatever the highest setting that both the source and display are capable of will be your maximum setting.

 

1080p 120Hz is possible over HDMI 1.4a but it is an unofficial mode, meaning it won't appear as an option by default and displays are also not required to handle it so it is not guaranteed to work. To try to enable it you need to set a custom resolution using the NVIDIA control panel or ToastyX's Custom Resolution Utility. HDMI 1.4b was the first HDMI revision to add official support for 1080p 120Hz but this has nothing to do with cables. If the display supports HDMI 1.4b and the laptop supports 1.4b, then you will have a 1.4b connection. If either of them doesn't support it (which the monitor doesn't, in this case), then you won't have a 1.4b connection, simple as that. Getting a special cable won't make the display suddenly know how to handle 1.4b signals.

 

HDMI does not adapt to Dual-Link DVI, so HDMI to DL-DVI adapters do not exist, anything claiming to be one is just an HDMI to Single-Link DVI adapter with extra dummy pins which don't do anything, hence the 60Hz limitation you've discovered, which is the maximum of Single-Link DVI. To change HDMI to Dual-Link DVI you need a signal converter, however you would never be able to go beyond the capabilities of your original source anyway, so there is no adapter that will help this situation at all.

 

If you can't get the display to accept 1080p 120Hz over HDMI, there's really nothing you can do, sorry.

ok, huge ty for info.

 

i guess 80hz with hdmi 2.0 is best i can do here. Atleast better than 60.
