To what dell laptops can I connect a Dell u2711 at full resolution? 2560x1440
What connection to use? DVI (Dual Link), HDMI, Display Port?
Does Dell Studio 1558 is capable of that? Maybe new latitudes and precision?
Sorry - I cannot help with the specific Dell laptops part. It will depend on the graphics card (which you can look up) and the output options from each model.
However, apparently, DVI (Dual Link) and Display Port both work at full resolution (i.e. 2560x1440).
It would appear that HDMI should also work, as long as you have a "High Speed" / "Category 2" connection; however, I am having problems in getting this to work.
At present, I appear to be limited to 1920x1080 over HDMI. I can get more via VGA and understand that my graphics card is not the problem.
Perhaps someone can help iro how to get 2560x1440 via HDMI out and answer your question iro which specific Dell laptops you could use.
