Intel HD Graphics 4000 card and laptop with ony mini VGA&HDMI port - how to run 2560x1440?

[GaKoon]

Hi.
I naively bought Acer B276HUL Aymiidprz 27" WQHD (2560 x 1440) display. I own ASUS UX32A with graphics card Intel HD Graphics 4000. My laptop has only USB, HDMI and mini VGA port.
I'm using HDMI connection but it only supports up to 1920x1200. I read that I need display port connection for 2560x1440 resolution.
Is there any solution to run display at best resolution?

if the monitor has max 2560x1440 resolution & as you do not have a displayport on that monitor then it means for the hdmi.

it is your onboard videocard is the problem.

I don't have displayport on my computer. Monitor has diplsayport.
I used http://www.notebookcheck.net/2560x1440-or-2560x1600-via-HDMI.92840.0.html this solution. It works. I still have a couple of questions:
Is it safe?
Is there any way to connect laptop and monitor via displayport cable and achieve best resolution?

does it get your wanted resolution?

does it get your wanted resolution?

Yeah, thank you.
Can you also answer my other two questions, please?

get a laptop that has a displayport builtin so don't need to use an adapter or an adapter cable.
if you are getting the resolution you wanted then how can you achieve the best resolution when you already have it?

If I use display port to hdmi adapter for connecting display port cable to my computer; is it the same as having display port connection or is it the same as having hdmi connection? Thanks.
I meant there is some cost anyway; 5 Hz less refresh rate and only reduced blank timing standard. Resolution is the same, yeah.

both are digital.
