Can the 2011 Mac Mini support 2560x1440 through HDMI port?

I can confirm that the 2012 can also drive 2560x1440 through the HDMI. I had to use SwitchResX. The Pixel clock is still limited to 162Mhz. In SwitchResX I was able to drive my Dell U2711 at 40hz when I used CVT-RB as the custom settings method. 40hz isn't ideal of course but is plenty as I am using this as a secondary monitor, the primary is a 30". I have been able to drive the U2711 using HDMI or the HDMI to single link DVI dongle. For some reason the colors look washed out using the HDMI so I'm going to stick with DVI.

I used the same settings as you to connect my 27" Eizo over HDMI. Works fine, but I'm wondering if there may be any side effects from using 40Hz. This is just the screen refresh rate, right? Shouldn't affect the color calibration etc?

thanks for any knowledge that someone here may be able to share.

Your input to this thread has been excellent, thanks terraphantm!!!

Wonder if anyone has sent feedback to Apple about limiting the hardware through their software? As this doesn't affect their Thunderbolt display, I imagine if this is not deliberate on Apple's part, they don't have much incentive to fix it. If HDMI worked, I could use a £380 2560x1440 27" IPS Asus and still leave my TB port free without restricting me to pass-through only accessories...
