Not with a laptop, but my second pc has 2 monitors connected with different resolution. KDE does recognize them correctly and I can position them by drag and drop in the screen settings. No problem so far. My problem was/is, that I'm looking for a desktop that spans multiple monitors, which apparently does not exists for the reason of different sized monitors.
