As the LG UltraFine 21" 4K display has a shipping time of 5-7 weeks and a rather high price: What 4K displays are suggested to use with the new MBPs? I've not heard of any others with USB-C/Thunderbolt 3, so I'm wondering if one should look for displays with HDMI, Thunderbolt 2 or other connection types. Especially as it seems that there's a high chance to end up with a 30Hz refresh rate (but I'm unsure if that's a limitation of the dongle or display or connection type). PS: as I'm not willing to carry my charger from place to place, I'd prefer to charge my MBP via the display. In case that's not possible with anything but the new LG, I'd have to factor in the price for an additional charger (and the necessary dongle from USB-C to whatever is suggested). Thanks.
