Hasta La Gadget!

I am quite sure that many of us have heard about Raspberry Pi, the tiny single board computer module that has made it possible to come up with some zany computing solutions. Since imitation is the sincerest form of flattery, here we are with the Banana Pi, a $57 clone of the Raspberry Pi. The Banana Pi sports a 1GHz Allwinner A20 dual-core ARM Cortex-A7 processor, while sporting double the amount of the Raspberry Pi’s RAM at 1GB.

Other hardware specifications of the Banana Pi include an SD memory card slot, HDMI and composite video jacks, a 3.5mm audio jack and a built-in microphone, Gigabit Ethernet, a couple of USB 2.0 ports, a micro USB port for power, an IR receiver, and even Raspberry Pi compatible headers such as a 26-pin header and camera connector among others.

To put it in perspective, it ought to be simple enough to use majority of Raspberry Pi-compatible hardware with a Banana Pi, and considering how the Banana Pi is more powerful than its fruity counterpart, it would be useful in the construction of a home theater PC or even a general purpose computer. What do you think of the Banana Pi so far? Personally, it might not end up being as successful as the Raspberry Pi due to the latter’s authenticity status.

I guess you can say that it would be a whole lot more disastrous in terms of productivity if an app, or a suite of apps such as Microsoft Office were to be crippled in a day, as opposed to say, Twitter, Instagram or Facebook going down for a while. The latter three would be an inconvenience though, that’s for sure. Well, Microsoft’s Office platform has long been the cornerstone of productivity in the enterprise and classroom environments, being made available on the iPad recently, but it seems that there is a new Office Mix in the works that will target the classroom.

Most of us would not be familiar with what mix.office.com is all about, but it so happens to be a brand new service which will be able to transform PowerPoint presentations into interactive, online lessons, allowing you to share those with just about anyone and everyone. This would be a novel method for educators to distribute and interact with their presentations

MIX would also enable one to transform PowerPoints into interactive online lessons as well as presentations, helping get rid of boredom in the classroom. There is an add-on which is installed that lets you record audio, video, and handwriting, as well as being able to insert interactive elements such as quizzes and CK12 exercises. Apart from that, there is also a screen capture tool that allows you to record anything you would like on your computer. When done, click “Create MIX”, and some XML mix will turn it into an interactive document that is complete with analytics. You can sign up for the preview here.

It’s not news that the Chrome support for high DPI (hiDPI) has been a work in progress for some time, and within the past year or so, the proliferation of high DPI displays on laptops has made the need for good high dpi support even more important. I have messed with a few beta features before, and some of them ended up making Chrome completely unusable.

I mostly tolerated the lack of high DPI on 13.3” laptop screens, but now that I work with a 32” 4K desktop display, I can no longer use Chrome without true high DPI support. Unfortunately, the old tricks won’t work anymore, but fret not there is a solution that does.

Context

For this tutorial, I have used:

• A Dell 32” 4K display
• A GeForce GTX 760 card (Display Port to Mini-DisplayPort cable)
• Windows 8.0, then Windows 8.1
• Chrome Version 34.0.1847.116 m

Past hacks

In the past, you could go to the Chrome settings and enable hiDPI from there. Here were the steps, which now no longer work:

1. In Chrome, go to “chrome://flags”
2. Search “HiDPI Support” in the settings
3. Make it go from “Default” to “Enabled”
4. Restart Chrome

First of all, it may have worked at some point, but a lot of people got burned out when Chrome turned into a garbled mess which was unreadable. The solution was to go back and fix this by following the same steps, but “blind”. I did it, it wasn’t fun, and re-installing Chrome didn’t solve it since the settings were apparently left in Windows after the uninstall. This option was removed around March 13 2014.

You may also find a second proposition which consists in adding command-line arguments to the Chrome app shortcut to enable HiDPI. They look like this:

–high-dpi-support=1
–force-device-scale-factor=2

There are TWO hyphens, and unfortunately, neither combinations work with the latest builds.

New Solution

The Chrome product support page is not really of much help, but fortunately a friend of mine pointed out that this was an active issue that was being tracked in by the Chromium development community.

I headed there and found updated information including a fix that actually works on my system and that I expect to work on most systems.

The most recent version of Chrome toggles the hiDPI support based on a Windows Registry value. This is why the old tricks don’t work any more.

I know that’s it is a pain to edit the registry files, but fortunately, some handy little files are already available on the Chromium site. Fair warning: this is not something that Google officially supports, and you run registry commands from an unknown source at your own peril.

1. Follow these links to download the registry files to Enable hiDPI and to Disable hiDPI support.
2. Once downloaded just double-click on one of the scripts
3. You will get a Windows security warning saying that the scripts could not be verified
4. Click “Run”
5. The Windows User Account Control will ask you to confirm. Click “yes”
6. The Registry Editor will issue a warning saying “Adding information can uunintentionally change or delete values and cause components to stop working correctly. If you do not trust the source of this information in [file path], do not add it to the registry. Are you sure you want to continue?” Click Yes
7. The registry editor should confirm that the “keys and values contained in [file path] have been successfully added to the registry”
8. Close and restart chrome
9. HiDPI should be enabled!

Thanks for Eugene Girard for uploading them to the Chrome Google Groups, and to Alex Sorokoletov for fixing an encoding issues on the original scripts.

The good thing with these, is that even if Chrome became or garbled, you could disable hiDPI support without going in blind and angry.

Additional Note

By default, Chrome is launched by Windows with some old display scaling on hi DPI displays. This is what makes the fonts blurry to start with. Even if you don’t enable Chrome’s built-in hiDPI settings, running Chrome with “Disable display scaling on high DPI settings” will help make the HTML text not blurry — although they may appear very small. This doesn’t solve the hiDPI issue, but it does help somewhat if you can tolerate using a 100% scale (no scaling).

1. Find the Chrome shortcut on your computer, or create one
2. Open its properties
3. Go to the Compatibility Tab
4. Check “Disable display scaling on high DPI settings”
5. Click on OK or Apply.
6. Close and restart Chrome

Pending problems in hiDPI mode

I’m glad to report that the steps above helped me setup Chrome with my hiDPI display. However, I have noticed that the Chrome window now sometime refuses to be moved and/or resized for some period of time.

If I wait long enough, the freeze magically go away, but this is something that I had never experienced before switching to high DPI mode. In the meanwhile, all HTML functions still work properly and you can read/browse the content.

Keep in mind that hiDPI is still very much under development, so things may change and be unstable until this feature is officially rolled out. If that is of interest, you can follow the code issue tracking #149881.

Finally, even after getting this to work, I noticed that hiDPI support was still better on both IE and Firefox, so if all else fails, you can still fallback on these.

Conclusion

Follow these steps at your own risk. It worked fine for me, but I haven’t had the opportunity to test them on other systems. I hope that it helps you enjoy your new hiDPI display.

If it doesn’t work, or if you have additional questions, drop a comment, and I will help if I can. If not, maybe someone else in the community can pitch in. If a few can pitch in a little, everyone’s computing experience will improve.

We have heard about Google’s Project Loon before, where this initiative intends to bring Internet connectivity to the masses using air balloons that float up high in the sky. It takes less than a month to make its way across the world, and has the potential to deliver up to 10Mbps speeds for users. It seems that these high-flying Wi-Fi balloons could also be testing out 4G LTE connectivity as they make their way on top of the Nevada desert.

So far, Google has already testing out its Project Loon Wi-Fi balloons in New Zealand, and hence it is not surprising at all to see that tests are also been conducted secretly right there and then in their very own country. So far, Google has picked up permission from the US Federal Communications Commission (FCC) in order to test out its Project Loon balloons in the northern Nevada desert.

In such tests, Google too, could be making an assessment as to whether it is able to tap into licensed radio spectrum to broadcast Wi-Fi. At this point in time, Project Loon has made use of the unlicensed 2.4GHz band for its Wi-Fi testing, where they are now also testing out a couple of radio spectrum types as depicted in the FCC filings, citing a broad class signal which could point to the possibility of 4G LTE.
