I have a T540p together with an Ultradock (135W). I use currently two external monitors, one HPZR30w with 2560x1600 and one Dell with 1440 lines. The latter work without problems at the laptops own DisplayPort Mini as at the DP port of the Ultradock.
The first monitor with high resolution doesn't work stable at the DP Mini !. But it works (except of 1-2 days ..don't know) at the Ultra dock.
I am not glad about this obviously quality problems- but at the end I can live with that. Other people maybe has had more problems with this.
But now to my real question: I would like to buy an Acer monitor with 3840x2160, but I am a little afraid of it, additionally some things I remember from people with even more severe problems like me.
What is the maximum resolution supported by DP Mini and DP of Ultradock and has anyone experiences with 4K monitors?
