It’s slow (at 15Hz refresh rate currently) but I’m enjoying near Ultra High-def resolution on a secondary monitor paired with my Late 2011 Model 17″ Macbook Pro.

Thanks to my friend Chris’ suggestion I bought a Seiki SE39UY04 on Amazon for a steal.

With the help of SwitchResX I’m able to make use of the full 3840×2160 resolution it offers. 

When using the monitor at the super high resolution the mouse cursor is really quite slow but for web development and general system administration it’s extremely useful to have an extra monitor attached to my macbook running 3840 x 2160 resolution.  I’m quite happy however this definitely makes me want a newer Mac that can handle UHD. ^_^
