Sounds good but i don't think this will come into its own until DP 1.3, isn't DP 1.2 limited in maximum resolution ? So people plugging in a mobile device may not be able to take advantage of higher resolution displays, like a 4k monitor.
Current generation graphics cards all specify a maximum resolution of 4096 x 2160 @ 60 Hz over DisplayPort 1.2. DP 1.3, when GPU manufacturers start to support it, will enable 8K displays, or a maximum of 8192×4320
Forgive me if I've got this wrong, 4K is 3840 x 2160 yes ? so at present DP 1.2 supports 4K. Would (I'm guessing) using some of the wires in a DP cable to carry USB and power reduce the maximum resolution a DockPort could display ?
I need to read in to this more, but I don't think the author is mentioning the limitation. Dock Port, or at least last I read on it a couple of months ago only supports USB3.1 if it is NOT also carrying full video. If you are pushing something like 4k over it, I think it only supports something like USB2. Not even USB3.0. Its very bandwidth constrained compared to Thunderbolt. I mean, it IS a nice step forward, but it doesn't really compete. Not really.
'The author' didn't mention it 'cos 'the author' hasn't heard anything of the sort - and can't find anything in previous write-ups or official documentation, either. Got a source on that claim? EDIT: The closest I've found is a comment on AndandTech's write-up of the same press release, claiming "The problem with Dockport is that in it's current iteration you're limited to 2560x1600@24bit/60Hz with Displayport 1.2 + USB 3.x" - but again with no citation.
Sorry i wasn't meaning to start an argument I only asked because i was curious if DockPort comes at the expense of a lower maximum resolution, making it (maybe) not as useful for mobile devices until DP 1.3 increases the available bandwidth. By the sounds of it the technical details are a little thin on the ground at this early stage.
Please. Either DockPort gets some serious traction, or Intel improves (and makes massively cheaper) Thunderbolt. Either way I'm happy. Laptops/tablets/phones need this. It will also make desktops a lot neater – I'd love to have 3×4k screens with a USB3 hub coming (with power) from a single cable from the case, that would rock.
