I recently purchased the following RX 480 to replace my R9 270 card. My 270 had a DVI-D port on the back of it. I used this to connect to my Acer GN246HL 144hz monitor. Everything worked as expected, I could select 144hz from within windows 7 monitor settings. Joy.

I have now installed the 480. It does not have a DVI-D port. It has three display ports, and an hdmi port. I ordered the following display port to DVI-D cable, and connected to my monitor. The default resolution in windows is 59hz, with the max being 60hz. No options to go past 60hz. Sadness.

I downloaded the newest version of drivers from amd for this card and did a clean install. Still...only 60hz max. Depression.

What is the problem here? I'm starting to pull my hair out !0_0!

nope that one is no good, they cost around $100 unfortunately. like bignastyid said you are better off replacing the card for one with dual link dvi-d if you still can. if not, best option would be a displayport monitor like you mentioned to get true 144hz.

its the cable you bought. no wonder the brand is called "BuyCheapCables". they give no useful information. you need to buy an active adapter.

some amazon Q&A about what you bought

Review: Do not buy for 144hz
Although it says its dual link, it only really does the stuff that a single link can do, not 144hz compatible.

…These are cheap fake Dual LINK. only supports 60hz instead of reaching 120-144hz they only reach 60hz.…I have been trouble shooting my new monitors all day and finally swapped out these cables for true DUAL LINK cables and was able to hit the 144hz. see more

You'll need something like this:

be aware that even with the active adapter you may not get over 120hz with that type of connection.

You would need a displayport to dual link dvi adapter and they are not cheap and are also not very reliable when trying to get 120hz+. You best option if possible is to return the current 480 and get one of the 480s that have a dual link dvi port.

Soo...This guy is a no go too?

Am I better off just to cut my loses and purchase a monitor with a display port jack that can do 144hz. I mean if i have to spend $100 on an adapter that can only hit 120...might as well right?
