The Grand(ish) Experiment – Two weeks in

It’s been two weeks since I started using the Dell tablet in anger. You may be wondering where the promised updates have gone. Well, here’s one.

I think that the biggest question that I needed to answer was “Can one of these tablets cope as my primary workstation?”. The answer to that is an unequivocal “Yes”. I have been using a Dell Venue 11 Pro 7139. This tablet has a dual core 1.6GHz Core i5, 4GB RAM and a 128GB SSD in there. It is more powerful than a significant portion of the desktop machines in our college and frankly, I would be shocked if it couldn’t. The only thing I’d really want from it would be some more RAM, 4GB is a bit tight these days; sometimes the tablet would freeze while I was using certain System Center components which can be a bit RAM hungry.

The dock that we received was a revision A00 dock which appears to have some issues when using it with multiple monitors. You may recall in my last blog post that I mentioned that I was having difficultly getting a DisplayPort to DVI adapter to work and that I thought I would need an Active one instead. Well, I ordered an Active one and that didn’t work either. This should be a supported configuration. After a bit of research, I found out that that Dell have put out an A01 revision of this dock which fixes these issues. It looks like Dell still have a load of stock of the A00s as the order number on the box was from the end of November and it’s a complete lottery as to which revision you’ll get when you order one. We ordered ours from BT Business so maybe you’d have more luck if you ordered from Dell directly.

This aside, the dock still worked with the DisplayPort to VGA adapter that we ordered so I have been using that to connect my second monitor. This has been OK but there has been the odd occasion where the tablet “forgets” that there is a monitor attached after the displays or the tablet wakes up  after going to sleep. Sometimes telling Windows to reactivate the display works, sometimes you need to undock and redock the tablet to force it to start working again. However, I don’t think that this will be an issue for the people who are going to end up using them as most of them won’t have two monitors attached.

The DPI difference between the tablet’s display and the external monitors has been a source of annoyance for me. Each time I undocked the tablet to use elsewhere, I ended up logging it off and back on so that the desktop was usable. When I redocked afterwards, again I logged off and on so that everything wasn’t massive. Again, I don’t know if a teacher would find this to be an issue.

As a point of interest, when the new Windows 10 build (9926) appeared, I installed it on another 7139 I had lying around and the same resolution issues were still there.

There are still a few things for me to test; I’ve not brought it home to try yet and I haven’t had the opportunity to take it to many meetings. I haven’t tried it in a classroom scenario with visualisers and interactive whiteboards either which is something I will need to do.

The next step is to give a dock and tablet to a teacher and see what they make of it!
