I have a Dell XPS 15, late 2013 and it has a Mini DisplayPort and an HDMI slot.
I am aware that different versions of HDMI support different resolutions and even different drivers affect things, too.
I would like to purchase two external monitors for use with my laptop and am looking to optimise the resolution (the XPS 15 comes with QHD 3200 x 1800 and Windows 8+ doesn't play well with scaling differently on multiple monitors).
Is there some software I can install, or some method within Windows, to tell me what resolutions my ports will allow?
I have tried downloading the specifications sheet for the XPS 15 and it doesn't even tell me which HDMI version is installed :(

Even if it was in the manual, I'd like to know if there is some software that can tell me :)
