I need help for connectivity for dvi at 144hz

[wassim.oussara]

Hi, I have 3 monitors, but i only have one port left on my graphic cards and it's an dvi port, but my monitor only support display port and hdmi, so is there a way to send 1080p 144hz from an dvi port to an hdmi or dp. Or can i use an hdmi splitter. Can someone please link me an amazon product like and cable or an adaptor.

You need a Dual Link DVI-D Cable or Adapter to HDMI to get this working but there will be some luck involved.

 

EDIT: you also have to find out if your DVI Out is even Dual Link DVI-D capable.

And the GPU needs to actually have a dual link output.

That's single link DVI adapter cable , max 1920x1200 60hz

 

To sum it up.

Your video card MUST have Dual Link DVI connector and the wires going to it - some video cards are only Single Link.

You must have Dual Link DVI cable - cheap cables are DVI Single Link.

Pretty much ALL  DisplayPort - DVI or HDMI - DVI cables are  Single Link - maximum 1920x1200 60 Hz because you would need an actual processor to generate the DVI signals otherwise - Single Link is easy, Dual Link is hard

Cheap passive HDMI-DVI adapters are only DVI Single Link because that's the easiest to convert between HDMI

 

If your video card has no Dual Link DVI the only solution is to get an expensive ACTIVE converter that converts DisplayPort to Dual Link DVI ... good luck with that.  It's probably about as expensive as an actual 144 fps monitor.

no that will not work its only displayport to dvi and I need the opposite

My gpu do have an dual link dvi port so could this work:https://www.amazon.ca/-/fr/Cable-Matters-Câble-bidirectionnel-câble/dp/B00K7HECTQ/ref=pd_vtp_147_4/132-1902655-9489662?_encoding=UTF8&pd_rd_i=B00K7HECTQ&pd_rd_r=85386bbb-3718-4e94-a813-31f15675f520&pd_rd_w=7280p&pd_rd_wg=S8fUR&pf_rd_p=0a2e1d15-5f67-4917-b635-3843e028c1f8&pf_rd_r=57GHM6V0RB9905BVH2Q7&psc=1&refRID=57GHM6V0RB9905BVH2Q7

Yeah the gpu port is an dual link

It is an dual link dvi port

That's a HDMI splitter , it splits a HDMI signal in two, making duplicate. The description also clearly says it's up to 1080p.

 

Is anyone incapable of reading descriptions before posting?

 

Again,  NO CHEAP converter /adapter cable will convert to DVI and give you more than 60 Hz.  CHEAP meaning anything less than around 60$ if you're lucky.

 

Lots of ACTIVE HDMI->DVI  or DisplayPort -> DVI will convert up to 2560x1600  (more than maximum of 1920x1200 Single Link DVI) but still maximum 60 Hz, NOT 144 Hz.

 

Here's an example : https://www.amazon.com/StarTech-com-DisplayPort-DVI-Adapter-Dual-Link/dp/B00A493CNY/

Spend $100+ on a converter that does Dual Link DVI which can go above 1920x1200 but you STILL get only 60 Hz

 

Or you can spend 15-30$ on  Single Link (maximum 1920x1200 60Hz ) : https://www.amazon.com/StarTech-com-DVI-DisplayPort-Adapter-Converter/dp/B077FYJTDL/

This converts a DVI to DisplayPort  (one direction only)

AFAIK HDMI and DVI is electrically identical, adapter are just a cable with two different plugs on either end, theoretical you can DIY one out of two cables. DVI is just missing a few pins like Audio and Ethernet. Also the twist of the wires is different and the shielding, like with CAT5 and CAT7. DVI is missing the data pin for the Handshake HDMI does for DRM and all that stuff. But I don't see why he shouldn't just buy a cheapo adapter and set up the refresh rate with a custom resolution.

 

Edit: 

Should do the trick:

That's PARTIALLY correct.  DVI Single Link is a subset of HDMI, or "supported" by HDMI.  

 

DVI supports only RGB, HDMI and DisplayPort support RGB, YCbCr 4:4:4 and YCbCr 4:2:2. 

DVI Single Link supports up to 1920x1200 60 Hz  OR 2560x1600 30 Hz ...

 

Again, you're another person that's NOT READING WHAT THE OP WANTS.  He wants 144 Hz, and that's just not possible with cheap adapters, because 144 Hz is only possible using Dual Link DVI and custom resolutions and refresh rates that aren't HDMI standard.

 

Cheap adapters that claim support for Dual Link DVI, basically support a SUBSET of Dual Link DVI  - they support 2560x1600 and also support 60 Hz, which is something Single Link can't do - Single Link only does 30 Hz at that resolution. The processor inside which converts the HDMI signal to dual link DVI can not do more than 60 fps.

I would just try it with the cheap adapter, like I said they are electrically almost identical, dual link just uses twice the TMDS channels, as long as the GPU doesn't refuse to push the data at higher frequency there will be no problem.

Also I absolutly wouldn't get an adapter with a processor that merges the TMDS signals because the OP will probably game on his 144HZ tripple Monitor setup and those adapters will completly dump your latency and therefore synchronisation.

It will "refuse", since it's a DVI output it'll run at DVI spec, not twice that.
