hi, So the Lg 5K can be attached to older computers like 2015 MacBooks or the nMP via a TB2-TB3 adapter. Can anyone please take some pix, a video of maybe even just describe how the picture looks like in such a setup? I'm having a hard time imagining it would look any good, reading that it's being upscale from 4K thunderbolt 2 Signal to 5k inside the display. But if there'll be a new Mac Pro later this year, and if the image right now looks good enough (like maybe a 4K screen scaled to 1440p), id love to snap 2 of these LGs right now while they're rebated. My Apple Store doesn't have them on display, so please, can anyone try this out?
