Only 120hz on a 144 hz monitor

[NexyV2]

Today i got myself a new monitor with 144hz.(Iiyama GB2488HSU-B2)
When i tried to set it to 144hz, it only showed up to 120hz in windows display.

I updated my drivers and disconnected my monitor multiple times.

It's currently connected with a HDMI Cable (the shop told me that it should support 1080p @144hz. the package shows that it supports 4k, not sure if it that tells you anything)
The reason why i got a hdmi cable is that my videocard doesn't have a display port but only 2 mini display ports. For some reason display>mini display port are really expensive here.

my videocard: radeon hd 7970 double dissipation

Download your monitor driver fromVG248QE Windows 7 driver, this is a link directly to the site download.

[strike]Please also open up your nvidia settings, change it to cap the frames at 144hz, in device manager Make sure under your monitor after the driver is installed, Right click it, properties, and change the maximum reported refresh rate to 144hz.

Also make sure that all your settings for video through nvidia are all set to uncapped framerate, otherwise it may lock you.

please post results.[/strike]

EDIT: After a little research, YOU CAN ONLY GET 144HZ WITH DP
These are the limitations of the HDMI

In order to get your full 144hz at 1080p you should switch to the display port.

1.4HDMI IS ONLY CAPABLE OF 120hz

Thanks! i don't have a display port, but only 2 mini display ports. The question now is... can i use a display port > mini display port to get my 144hz?

Mini Display port is the same as Display port, just a mini form factor.

You can easily get a mini DP to display port cable from the store, or buy an adapter for mini dp, to display port.

This will get you 144hz no problem, and the ability to render even higher resolutions.
