Dock external video troubleshooting and single thread
Trying to consolidate all of the dock video threads into a single one. This will help me to gather information on what is and is not working out there and get it to engineering to resolve. I'll edit this first post to keep everything updated in one place. This should make it much easier to find information going forward.
Steps to take before reporting an issue:
1) Check the revision on your dock. If you look at the bottom of the dock, you will see a variety of labels. The PPID label is on the right side of the group of labels and will include a revision number at the end. Verify that you have an A01 revision. If you have A00 and if video doesn't work after trying the remaining steps in this guide, contact support and have your A00 replaced with A01.
2) Be sure to update your device to the latest BIOS (currently A11 for the 713x and A07 for the 5130). For the 713x, select the appropriate version for your product.
3) Update to the latest video driver. This is currently 3496 for the 713x and 3366 for the 5130 (note that 5130 driver is bundled in the A06 chipset driver).
4) Connect your monitor(s) to the dock. The preferred method is to use straight DP to DP or HDMI to HDMI cables. Dongles will work, but note that DP dongles must be "active". DP++ dongles (non-active) will not work with this docking station. Passive HDMI dongles are OK. Use good quality cables and dongles. Monitors should be HDCP compliant.
5) Turn monitors on and set up external video either via the Intel graphics driver options or via WIndows Devices/Project option. The 5130 will support the LCD + one external display (two displays can mirror content if desired). The 713x will support the LCD + two external displays (each displaying unique content). The 713x will support daily chained DP 1.2 monitors. Dual external monitors can run at FHD (1920) and a single external monitor via DP can support 2560.
6) At this point, your external monitor should be working. If it is not, a couple of additional troubleshooting steps to take follow.
6.1) Remove and reinsert monitor cable to dock.
6.2) Make sure dock power is good (LED at front of dock should always be on when good power is present)
6.3) Make sure that monitor has correct input source selected and that cabling is routed to correct ports.
6.4) Undock and redock tablet to see if any change occurs.
6.5) For the 713x tablets, try rolling back to the A00 video driver 3316 to see if this makes any difference.
7) If external video is still not working as you expect it to, please post to this thread with the following information.
7.1) Confirmation that you have tried the above steps and that you do indeed have an A01 dock.
7.2) Brand and model number of your monitor(s).
7.3) Setup information (e.g. how is everything connected)
7.4) If using dongles, brand and model number of dongle if known
7.5) Specific problem(s) you are seeing.
Watch for updates to this thread as information develops. I'll be updating below tables fairly frequently - I need to dig up the test reports and add all of that information here soon.

Brian,
I am trying to determine the possibility of have two external monitors (and not using the tablet display while docked) connected to the dock and therefore having dual monitors?
Is that possible with the dock at this point (I was sold on that capability)? It doesn't say anywhere on the dock label Revision but the box does have an A01 at the end of the model number (CN-0MPT52-74431-43L-0010 A01).
I don't mind purchasing the correct adaptors as long as the dock I have will support dual simultaneous external monitors.
Thanks.
Randy.

How do you have them hooked up? One connection to the HDMI and the other through the DP?
I am not able to find the U2410 monitors on Dell's site. Strange.

Yes it works for that purpose. I use it as well.
U2410 monitors work the best

We're obviously chasing some DP gremlins here. I used dual external monitors on a tablet (set up for my work domain) all day on Thursday without any problems. Looks like the adapters that work for me don't always work for every monitor. The latest dock is indeed A01. Our engineers are working closely with the chipset vendor and Intel on this. Please keep providing detailed information here. I am compiling this and will get all of the known problems to them to resolve.

So I got the new dock in today and have noticed some improvement. I still have issues with certain videos though. For example, I tried out Youtube videos at 1080p and everything was smooth as it should be. Then I tried watching a video at Gamespot.com and I get the choppy video playback with smooth audio playback. Is it something to do with the difference in video players?
Here's a link to one of the choppy videos. Just to make sure it's not me, can anyone try to watch it and let me know if you experience the choppy video with smooth audio? It's noticeable when not in full screen and really bad in full screen.

Just to note, I have a 7139 vPro model, with only one monitor connected via direct HDMI. I'm still happy that Youtube playback has been improved and hopefully the other playback issues will be resolved in the future through patches.

I understand what you're saying, but I don't get how the audio would be uninterrupted while the video is just choppy. I guess I'll just have to watch the videos through YouTube instead. :(
