Question Dp-DVI-D cable not working

[Tuhoaja]

Just recently bought a new monitor that works fine with HDMI but I want to get the full 144hz out of it. I bought a cable that is displayport to the monitor and dvi-d to the computer. However, it's not working. What can I do or what I'm doing wrong?

You're not going to get 144Hz from a DVI-D port. DVI-D is used to produce an analogue signal (VGA).
Depending on your monitor, it's either going to be through the HDMI port, or through DP.

Oh ok, thanks.

But I'm pretty sure that DVI-D can produce 144hz?

That is WRONG. DVI-D -- "D" for DIGITAL does NOT have analog signals used for VGA.

DVI can support 120hz but it would require a dual link DVI interface. Some pages say dual link DVI will support 144hz. It would depend on the specifc adapter you have to determine if that is a supported capability.

What is the model of the monitor? What video card are you using? What adapter did you buy(make and model or a link to it)?

It is likely you bought a DisplayPort to DVI adapter, which will only work for DP to DVI connections, not DVI to DP as you are trying to do. See section 1.2 here: https://forums.tomshardware.com/threads/how-to-connect-to-a-120-hz-display.3268285/

The monitor that I'm using is Samsung C32JG50, and I'm pretty sure I have the dvi-d to dp

 

[Tuhoaja]

Yeah I just read that it's impossible to work that way, sorry for your time guys

Yeah - seems that I got them mixed up again.
Sorry
