I am thinking about picking up an Android tablet just to use as a Roon remote. The one I am thinking about getting has a resolution of 2560 x 1600. I want to make sure that at this resolution the Android app will give me the same functionality as the desktop program? In particular I am interested in alpha navigation and focus functionality. Right now, I am using my Samsung Note 3 phone and old Nexus 7 tablet as a remote but neither of these allow me to have the alpha and focus because (I think) the resolution is too low?
