Mini DisplayPort to HDMI Adapter Supporting 1080p Max

On my iMac (27” Mid 2010) I would like to use it with a 1440p monitor, but whenever I connect it to the monitor, it will only support a maximum resolution of 1080p. I discovered the adapters I had tried to use, only supported a maximum resolution of 1080p, so I purchased this: https://www.amazon.com/gp/product/B010SD... which supports up to 4K. When it arrived, I tried using it with the iMac but still it only would support 1080p max, so I tested the adapter with a 2013 MacBook Pro, and oddly it worked at 1440p.

Does anyone have suggestions to fix this strange issue?

Isn't 1440p 2560x1440? So wouldn't it support it, if it supports 2560x1600?

Natively via the DisplayPort, not through this HDMI adapter and is limited by the displays size as well.

@danj My monitor is a 27" monitor, and it does have DisplayPort, so would a Mini DisplayPort to DisplayPort cable work? Or would the monitor's specifications not work with the iMac?

Give it a try!
