Sorry for the lack of updates - have been travelling for work and time has been even more limited than normal. The workshop completed last month and Dell and our partners have been working on a new video driver. We originally had hoped to have this out by now, but a few additional issues were found and are being fixed. Current ETA for the driver is within the next ~10 days. If the driver is delivered on this date, it will be validated (~week or so, maybe a bit longer in this case) and then posted to support.dell.com. Goal here is to get all of these issues resolved, so while I realize you guys are frustrated, the engineers are working to resolve rather than rush. I'll keep you posted as I get the beta. I now have several of the monitors that don't work.
I have been able to get the P2210f working fine with the supplied DP to DP cable that came with the monitor. I used a bluerigger HDMI to DVI adapter for the other port and using the latest (A11) BIOS and video drivers (A02) with an A01 dock. I used to have to do a little jig to try to get them to work if the tablet rebooted, but since I did those updates everyting is working 100% of the time.
I was able to get multiple monitors working after driver updates mentioned in this post. however I still have a flickering when using VGA to display port. I am using DVI to HDMI via an adapter and it works very well. My monitors are both HP LA1951g
- Dock A01 revision.
- BIOS A11 on a 7130
- Driver 3496_A02
As this is finally headed towards Dell Engineering in a well defined manner, I just wanted to post a few big picture comments and observations on this topic based our experiences.
Our setup is as follows:
- Venue 11 7130 Pros with A01 DS, A11 BIOS, and 3496 (A01) video driver
What I want to talk about is what works consistently vs what doesn't and therefore elevate this conversation stream to focus on what MUST be the root cause heart of the issue here that Dell Engineering needs to address:
- When we connect the Venue 11 7130 Pro tablet's Micro HDMI port to virtually ANY of the problematical monitors listed in any of the various blog posts to date with an appropriate cable or cable + active adapter, it works. Similarly, no one has reported any issues outputing from their tablet to TV's of all sizes at home, etc.. This means that the fundamental issue is not with the tablet, or even its video drivers.
- To further bolster this conclusion, we tested the tablet hooked up to problematical monitors directly through a standard DEll USB 3.0 port expansion hubs. Both those expansion hubs with 2 traditional DVI video out ports and newer models with DP and HDMI video output port options. These hubs are using Display Link technology and drivers under the hood for video data handling. No problems!
- We also tested against the very similar, but single HDMI video output port, propriety I\O port DEll DS that shipped with the Lat 10's. An implementation that never had any of these issues. As long as you have a LAt 10 on that DS your OK, as soon as you have a Venue 11 configured to output at FHD resolutions, it usually goes south.
- To me, this testing clearly proves two things.1) its the move to FHD and support for the larger data streams those resolutions require that is part of the root cause of the problem. Increased power needs to drive that might also be in play. 2) That the root cause of all these issues is the DEll A00 + A01 DS's proprietary interface port where the tablet joins the DS and starts routing its video I\O through that port once docked. That's the difference between the USB 3.0 hub test and the Venue 11 DS tests. Clearly the drivers and technical specifications behind the new DS for FHD video data I\O routing in both directions are not solid. They were initially with the Lat 10 at 1366 x 768 and lower resolutions.
Please have the Dell Engineers focus on these facts.
I didn't hear anything on this last week so I thought I'd bump it again.
Any update when we might see the updated driver?
Dell Venue 7139
Purchased: May 2014
Driver: A02 10.18.10.3496
Cable: Dell DP to DP that came with one of our monitors.
Monitors Tried: Dell P2414Hb & Dell 2009Wt
We are having significant issues getting the DP to work on the Dock. We have a variety of Dell monitors.
Sometimes, if we dock and re-dock we can get the dock to detect the monitor. When it is detected, we can only get it to mirror the display on the Venue. If we set it to extend - we get a black screen on both the Venue and the monitor.
The Departments I support at my University were planning on investing heavily in the Venues to replace our laptops. But this display issue is an absolute deal breaker for us. The departments I support will not buy a single additional Venue until this issue is resolved. We may even consider Microsoft Surface Pro 3s
