More 120Hz problems

[CliffTerios]

Heyo, it's me again and I have done a little bit of research after the last post I made regarding my possible purchase of a 120Hz monitor. 

 

First off, the reason I'm getting a new monitor is because my brother gave this one to me temporarily until I could afford my own, since he uses his laptop nowadays anyway. Why is that important? Just so nobody says "if you already have a 120Hz monitor, why get a new one?" Alrighty.

 

So while doing my research I found out that the Acer GD245HQ is a 120Hz monitor, but only ran at 60Hz because I plugged it in via HDMI. As I learned, HDMI does not support refresh rates over 60Hz, so that's why my games always displayed 60Hz as the only option. 

Searching a little more, I found a forum post saying that a Displayport-to-(Dual-Link)DVI-D cable would support said 120Hz of my monitor. So I got myself such a cable. Besides noticing that the image looked much, much more crisp and that my speakers sounded much clearer being plugged directly into my PC than having all of it run over a cheapo HDMI cable, I still couldn't find a 120Hz option in any game I tried. Looking into windows, that also claimed that my monitor only runs up to 60Hz. So I'm assuming I've done something wrong and I can't figure out what. Can anyone help?

Sometimes you have to add a custom profile to get 120hz weird I know and why not just use a dvi cable?

The way my other monitors are connected to my graphics card is really.. Convoluted, to say the least. I didn't think it would make a difference, so I wanted to leave everything unchanged aside of switching the main one from HDMI to DP. 

I also really didn't think about it because that post specifically talked about DP to DVI-D. 

 

How do I do that custom profile thing?

DisplayPort to Dual-Link DVI adapters are all fake, they are only Single-Link in disguise, unless it is a signal converter ($80+). Whoever told you it would work for 120Hz is wrong.
