So i'm thinking of purchasing a DELL XPS 15 with a screen resolution of 15.6" 4K Ultra HD (3840 x 2160).
I already have a very nice DELL Ultrasharp 27 inch monitor with a screen resolution of 2560 x 1440.
I did the research and i believe it's better to use the USB type-c (laptop) to DP (monitor) to connect both instead of the USB type-c (laptop) to HDMI (monitor).
Is this correct? Is DisplayPort 1.2 better then HDMI to connect a laptop to a monitor?
If yes, my monitor comes with a mini DP... Should i use the USB type-c (laptop) to mini DP (monitor) instead of DP 1.2?
Also, what is the negative points of having to different resolutions connected? I guess i just want to make sure that i'm making the right decision before investing on a expensive laptop. Thanks all.
For more info, here are the connectivity specs from my DELL Ultrasharp U2715H:
Connectivity 2 HDMI(MHL) connector 1 Mini DisplayPort 1 DisplayPort (version 1.2) 1 DisplayPort out (MST) 1 Audio Line out (connect your speakers) 5 USB 3.0 ports - Downstream (4 at the back, 1 with battery charging) 1 USB 3.0 port - Upstream
