The bandwidth needed for 1080p@144 is roughly 8.96 Gbps based on this link http://k.kramerav.com/support/bwcalculator.asp. You will need to have DP 1.2 in your configuration, and by this I mean your graphics output, cable and the input of your T.V must be DP 1.2; so, in theory with this configuration you will be able to achieve it. However, before purchasing the TV, my recommendation is since you have a laptop you could take it to the store and see if you can achieve it, if possible do as much testing in order to check that resolution is possible.
Thanks for answering
I just had one more question, would it also be able to output at the same resolution (and refresh rate) using DVI-D (converting Mini DP to DVI-D) if the monitor did not have a display port?
