dkwollie · 04-18-2015, 03:05 PM

Hi, i bought a D3100 and P2715Q to using the display external in 3840 x 2160 resolution, but it have much latency.

My spec:

- Notebook M3800
- Windows 8.1 x64
- Dock Dell D3100 (DisplayLink)
- Monitor P2715Q 4k (3840 x 2160)
- The dock drive was downloaded in dell website (I tried 7.7 M4 and 7.4 M2 too)
- I using the DisplayPort cable (DP - DP), and i tried the mDP - DP too.

What should I do?

Can you describe 'much latency'?

We are capable of 30Hz update, which isn't the best, but good for most purposes. If you are seeing much worse than this, try to make sure you have a USB 3.0 connection, and not just USB 2.0.

Similar issue .. guidance appreciated

Dell M3800 4K
Dell D3100
Dell P2715Q

D3100 plugged to M3800 via USB3.0 port on left side of 3800 to back connection on D3100.

Drivers loaded before plugging into D3100 per user guide.

Something going on with M3800 display to P2715Q display sync ... P2715Q will not show full display as it appears on M3800 (looks like center portion ... can't see task bar) or icons on RHS or LHS of M3800 on the P2715Q). M3800 display goes unstable when plugged to D3100 ... generally black but will flash with mouse motion.

How to get P2715Q and M3800 to look same and both display? Got both with assumption that they were matched resolution and would be easy to replicate M3800 display on desktop for office use.

Thnx in advance.
