And the second question. U2713HM has a DIsplay port. Can I use miniDisplayport to Displayport cable to get the 2560x1440px resolution?
You should be able to... you may have to use an app such as SwitchResX to 'tinker' with the settings on your external monitor - but if both the monitor and computer are capable of 2560x1440 I don't see why you can't get that resolution - but I don't know - I've a 27" Apple Thunderbolt Display. Download a trial version of SwitchResX and see if you can get it to work with a Mini Display Port to DisplayPort adapter.

I've read that miniDP to DVI adapter doesn't support resolution more than 1920x1200px;
But, I'll try to do as you said. Thanks.

I think that you're correct - I just had a look at the Monoprice Mini DisplayPort to DVI adapter and it plainly states that it only "Supports up to 1920x1200 resolutions (single link)."
So even SwitchResX may not help you with resoultions up to 2560x1440.

I' try to use miniDP to DP. It supprorts 2560x1440px and I'll write here about results.

MiniDP to DP cable solved all problems. I'd just connected a monitor and a laptop and it works fine.
