Hi chaps,
I'm new on here, but I think I'm seeing the same issues...
I have a SP3 i7 256GB. A Dell 30 inch which has DP1.2, and an older dell 24 with DP1.1.
I run them as a daisy chain happily from my MacBook Pro 2013.
I'm going miniDP->DP, and then DP->DP
They run fine from the SP3 directly - the port on the actual device.
Connect them to the docking station - oh heck, what a mess.
Device/docking station less than a week old. (although no idea when it was manufactured). All updates applied.
Disconnect the 2nd monitor from the chain, and it performs perfectly on just the 30inch.
Cables matter! Of that I'm sure - my experience of getting DP running initially proved this to me, but my setup is stable where it works, so I think that is all ok.
So a few thoughts / questions if anyone can throw some light on this please:
1. The 30 inch is quite new, but this could be an compatibility issue with the hub in the monitor and the docking station DP? i.e. would buying an independent hub be a possible solution?
2. I'm reading that the USB->DP uses CPU? Not something I really fancy, giving this is just dual core. Anyone notice any impact with these adaptors?
3. Does anyone have a daisy chain working from the docking station with hi-res (i.e. above 1080) resolution? Or using a hub from the docking station? Basically like many people, I just wish to put the device in the dock without further connections.
4. Is there any difference in connecting to my Dell 30inch on full size DP port compared to connecting on mini DP? i.e. I currently connect minDP->DP, but I could I presume purchase a new cable and connect miniDP->miniDP.
Otherwise, what a wonderful bit of kit. And frankly there seems a way around this, even if its not necessarily as easy as it should be.
Many thanks
Graham
