PG278Q stuck @120Hz

[SpawNt0p]

Hello there!

I just received this fabulous monitor today and tested it tonight.

I'm fully aware I won't enjoy fully his features since I have AMD GPU's right now (Sapphire 7970 Dual-X OC x2), but my problem is that I'm stuck at 120Hz refresh rate.

I had a BenQ XL2420T (120Hz monitor) before, I used a DVI-D link to connect it to my top 7970 GPU.

The 7970 I have doesn't have Displayport on it, only Mini-Displayport, so I bought a Startech Mini-Displayport to Displayport link to connect my PG278Q to my top 7970 GPU.

Problem is I can't select 144Hz since it doesn't even appear on combo box.

In Catalyst Control Center, maximal refresh rate reported is said to be 120Hz...

I already installed the Swift driver (DVD given with the package).

Any idea?

Noticed something more (didn't paid attention at the beginning but it's like this since day 0), my LED is half green and half white, since I have AMD GPU's it's not supposed to turn green since it's for 3D Nvidia..



Guys? 😄
