JmGO G1 Smart Projector Review and Giveaway | Dramel Notes

Posted On // Leave a Comment

If you think a projector can’t possibly compete with your HDTV, think again! With a smart projector like the JmGO G1 Smart Home Theater, you get the benefit of a high definition screen that’s bigger than any television, plus a media streaming device – all in one beautiful silver disc. Interested in the chance to win one for yourself? Keep reading and get ready to rearrange your entertainment center!

We’ve already shown you how to set up a smart home theater and also what to take into account when you are selecting a projector. The JmGO Smart Home Theater condenses these two tasks into one, as the hardware you get contains the required projector and speakers to fill a respectably-sized room with sound and a screen large enough to fill all but the most imposing walls.

Specifications

The JmGO Smart Home Theater main unit is consists a round, disc-shaped projector. It also comes with an AC power cord and adapter, a remote control, and a bracket joint.

  • ARM Cortex-A9 CPU
  • 2GB DDR3 RAM
  • 1.4:1 throw ratio (so to get a 100″ screen, you’d need to be 140″ throw distance)
  • 1280×800 native resolution (a little more than 720p)
  • 1500 lumens brightness
  • HDMI port, AV input, USB 3.0 port, USB 2.0 port, Ethernet connect
  • Android 4.3-based custom UI
  • 219 mm diameter x 60mm high
  • Supports 4k input resolution

Hardware

The silver, disc-shaped projector is very aesthetically pleasing. There is a forward-facing lens and the four speakers are built into the sides of the disc. The device is cooled via a fan on the bottom. The fan can be a little loud, especially in small rooms, but it is helpful to know that the complex internal hardware will be internally cooled; it isn’t obnoxiously loud as some projectors can be – you probably won’t notice it unless you’re watching a silent movie. The light ring around the power button has different colors to indicate it is powered on, on standby, and in Bluetooth speaker mode.

The JmGO comes with a bracket and three screws which will make it easy for you to attach it to a wall mount or stand. There are none specifically made for the JmGO, but the bracket seems fairly universal. A stand set in the middle of the room would also be ideal if you want to take advantage of the speakers built around the projector.

Of course, you don’t have to attach the projector to anything. The JmGO has a set of rubber feet on the bottom, allowing it to sit just as well on a shelf as anywhere else. Though for it to be projected onto a wall from a flat shelf, it should be placed on a relatively low shelf. The JmGO throws its projection high enough that any shelf above waist level will put the projection on the ceiling. The fact that there is no vertical lens adjustment makes physical movement of the projector the only way of getting the optimal image.

The device bears the distinction of being very easy to use. You plug it in and, without having to connect it to anything other than a power source, you can turn it on and use it. The home interface will pop up, and as long as the software is properly upgraded and internet available, you can pull up any video streaming software of your choosing and immediately begin watching – this will be a more than sufficient complete media center for most people.

JmGO Remote

The projector is controlled with the accompanying remote. While it may not be as impressive as some remotes, it is still very comfortable to hold and comes with a surprising economy of buttons for the functions it offers. There are four buttons on the top, two on the side, and one power button on the very end of the remote. There is also an analog stick above the top four buttons.

What the remote lacks in intricacy, it makes up for in comfort and functionality. The analog stick is intended to be the primary form of navigation, though many people will likely find the air mouse to be more convenient for typing and for moving through the time slider on a video player. There is a home button, a back button, and a mute button to make the most basic functions easy. There is also, supposedly, a microphone built into the remote, though I was unable to get it working for things like Google voice search.

The very end of the remote is a knob you can twist to adjust the volume. Pull the knob up, and you can use it to change the focus. This is especially convenient for first-time projector users and those with brand new set-ups, as the projector is unlikely to have a sharp image out of the gate, depending upon where it is in relation to what it’s being projected on.

Software

Software upgrades are easy. You just have to click on the Upgrade button on the settings menu and the software is updated quickly and easily. Similarly, the interface is direct and simple to navigate. It is custom UI based on Android 4.3. All of your apps are downloaded via the Google Play store and appear on a single screen, while your auxiliary devices appear on another screen, and your settings on a third.

You turn the JmGO on, and all of the software is ready to go right out of the box! You have immediate access to YouTube, Netflix, Hulu, and any number of other sites. All you need to do is hook your projector up to Ethernet or local Wi-Fi and the internet is at your disposal. You will need a Google account in order to download and install apps from the Google Play store, of course.

Sight & Sound

The projector has excellent color, and is best suited to a white, texture-less wall or separately purchased projection screen. While the projection has a tendency to be a bit lopsided if the device is off-center at all, this can be fixed with correction options in the settings. The brightness, zoom, and contrast are also all customizable, letting you fit the projection to the screen.

Note that the 1.4 throw ratio puts this in the realm of “long throw distance” – to get a really large projection size, you’ll need to be able to place this a considerable distance back from the screen. This shouldn’t be a problem in most average sized living rooms, but be prepared to ceiling mount this for the best experience. If you need something that will project a huge image from a much closer distance, look into a short throw projector instead, like the Optoma GT1080 and similar models (anything with a throw ratio is less than 1, basically).

The JmGO also has speakers built into the sides of the device itself, making the projector a contained home entertainment system in its own right. While the bass can be a little soft, the vast majority of sound that comes out of the projector is clear and crisp. With a Bluetooth connection, you can connect your mobile music players to the JmGo and use it as one big music speaker, albeit while it’s in standby mode.

At its maximum, the screen can theoretically extend to about 300″ diagonally, though you’d need an enormous living room to test that, which we don’t have. The JmGO G1 also features the option to choose specific aspect ratio, rear- and flipped-projection options, so you can project onto a number of different screens and mount on the ceiling.

Attached Devices

Of course, the JmGO can do much more than give you access to streaming sites. There are several ports built into the back of the projector, including two USB ports, an A/V port, and an HDMI port. You can plug in your DVD player, gaming console, computer, or any number of other devices. Have one of the many streaming devices available? You can use that too!

Once you plug in these devices and have selected them from the source menu, you can access all of their functions as if you were using them with a television.

Though the unit is equipped with Bluetooth, it’s of limited use: when the lens is off, you can use the built-in speakers for an audio connection over Bluetooth. The functionality doesn’t extend to act as an Airplay or Miracast target for visuals too.

Remote Problems

The Projector itself has few problems, but the remote that comes with it is a different story. While the twistable end of the remote does, in theory, allow for more precise adjustment, it can also be frustratingly oversensitive. It also necessitates using both hands unless the user is incredibly dexterous. You will never appreciate buttons quite so much as when you have to use two hands on your remote control just to adjust the volume.

The air mouse function is also rather imprecise, and would be a nightmare for someone whose hands shake for whatever reason. Frequently it will be oversensitive, veering wildly offscreen at the slightest shake of the wrist. And the analog stick is not often much better, as it gets very sticky and will lag behind the user’s thumb.

Final Thoughts

Other than these few problems, the JmGO G1 projector is exceptionally user-friendly. It both looks great, and performs well. The problems with the remote are negligible, and the JmGO G1 Smart Home Theater combines the functions of so many devices into one product, representing great value for money.

Mirror Anything from Your Computer to Your TV Using Google Chromecast | Dramel Notes

Posted On // Leave a Comment

Outputting your computer to your HDTV via HDMI works well. Unfortunately, your computer’s placement depends upon the length of the cable. With Google Chromecast, however, you can literally mirror any browser tab or even your desktop, from anywhere, in just a few clicks.

The point when video card manufacturers started including HDMI outputs was a great moment. Similarly, when TV makers began adding VGA inputs, we had yet another great way to add a huge second (or third) display to our setups. The implications, beyond the logical I-can-project-my-computer-screen-now train of thought were pretty apparent. If you wanted to use your TV now to play games from your computer, or watch movies on a big screen, you could now do so easily and cheaply.

The problem, as we mentioned, is that you have to set up your computer right next to your TV. Most HDMI cables are six to ten feet long. You can obviously buy longer lengths but the point is, even with all these fantastic projection capabilities, you’re still tethered by an ugly, black cable.

Enter Chromecast, Exit Cables

Google Chromecast is an amazing little gadget that costs less than a tank of gas. For $35, you get a tiny HDMI dongle that’s about the same size as a peanut butter cup, and while not as delicious, it does some pretty cool stuff!

One of the Chromecast’s best features is the ability to “cast” tabs or even your entire computer’s desktop.

The Chromecast version 2, comes in three colors, yellow, black, and red.

To get started, you obviously need a Chromecast. You also need to use Google Chrome and you should install the Google Cast extension. You might also want to install the Chromecast app while you’re at it, but it is optional.

Casting Chrome Tabs

With your extension installed, you can start casting, which is more akin to mirroring, but who are we to split hairs? To cast a tab, click the “Google Cast” button in Chrome.

If you have more than one Chromecast on your network, you’ll obviously see them here. Select the Chromecast you want from the dropdown menu and your Chrome tab will appear on your TV’s screen (just make sure you’ve turned your TV to the correct input).

If you want to stop casting, simply click the Cast button again, and then click “Stop casting”.

If you want to cast another tab, select it, click the Cast button and click “Cast this tab”.

Casting tabs is super easy, but your results may vary. It works fairly well though, and we don’t notice a disconcerting amount of lag and stutter.

You can also stream many video files in a Google Chrome tab.

If you are casting a tabbed video, you can click the full-screen button and it will fill out the whole screen on your output device. You can then tear off this tab as a separate window and minimize it to your taskbar or dock. Just keep in mind that, if you’re using a slower computer, you might notice your output quality suffer a bit if you continue to use your computer for other tasks.

Know also, not all video formats are supported. You can overcome this limitation by either casting your entire screen (described below) and using a video player like VLC, or moving the file over to your Android device and casting your screen.

Videos aren’t the only types of files you can display in a Chrome tab and ultimately cast to your TV. If you want to learn more, we suggest you read our article on four other file types you can display in Chrome.

Advanced Casting Features

Casting tabs is easy, but there’s far more to it than just that. Clicking again on the Cast button in Chrome (make sure you’re not casting a tab first), choose the small arrow in the upper-right corner, and you will see three to four other options.

Let’s go through and explain each one so you have a firm grasp on what they all do.

Casting Tabs Optimized for Audio

A lot of TVs come with pretty sweet speakers, or you might have added a sound bar recently and use it listen to Pandora, Spotify, or other streaming services. The problem with normal tab casting is that audio is played on the source and output device, which means you can get some really poor results. Furthermore, you might get an echo effect, such as if you have the same program playing on two TVs in separate rooms.

If you click “cast this tab (optimize for audio)” however, audio output will be completely routed to your output device. Not only will you not have to mute your source device, but audio quality should be fairly solid.

You can mute your audio from your device by clicking the little mute button as shown in the following image.

When you cast with optimized audio, you control volume using the app/webpage and/or your TV. Using your computer’s volume controls will have no effect.

Casting Your Desktop

If you want to cast more than one tab, such as another app, or simply your entire desktop, then you need to click “Cast entire screen”. Casting your desktop is labeled “experimental.” That said, in our experience, it works very well for something that is still under development.

Casting your entire screen means that you can move your computer anywhere, as long as it can send and receive data to your router.

When you cast your screen to your TV or similar device, you’ll be asked what part of your screen you want to share.

Once your screen appears on the output device, your computer will show a small control bar at the bottom of your display.

You can grab and drag this bar to anywhere else on the screen, or you can simply click “Hide” to make it go away.

In our experience, casting the screen is an ideal enough feature that you might bust out for presentations or just showing off a web page, but it may not be tolerable for video playback. That’s not to say it doesn’t work. In our tests, we tried playing a 650 MB .MP4 video on VLC on an aging but still capable desktop computer, and an even older and less capable laptop.

You can always stop casting by clicking the “Stop sharing” button on the desktop control bar or click Chrome’s Cast button and then the “Stop Casting” button.

The weaker laptop cast the video with a great deal of ghosting. The desktop fared somewhat better, with no ghosting, but lag and dropped frames made for a less-than-pleasant viewing experience. Changing the resolution on the source computer had no noticeable effect on output quality.

We assume the more powerful the computer, the better your screen-casting experience may be, but it’s definitely not going to offer the type of results that connecting computer directly to the TV will yield.

Casting High-Quality Video for Optimal Results

You may have noticed in an earlier screenshot, that there is a special option to cast websites such as YouTube, directly to your Chromecast.

You can do this on an increasing number of services such as YouTube and Netflix, just as if you were casting from your mobile device.

When you cast from Netflix, it still allows you to control playback from your computer, but the actual video is cast to your TV instead being mirrored.

Thus, you won’t experience quality problems because the video is being streamed directly from your router to your Chromecast, instead of from your computer, to the router, and then to the Chromecast.

Not all streaming websites support this capability but for those that do, it means Chromecast users don’t have to use a mobile device with a dedicated app to watch Netflix on their TVs.

What’s in Those Options?

Let’s wrap up with the options that you keep seeing when you click on the Cast button.

The Options are simple, you can choose the quality of your casting tabs.

If you’re experiencing far too many performance issues, then you can set the quality for a lower bitrate. This will obviously have a noticeable effect on how things appear on your output display, but it’s a great way to adjust for better playback when you’re casting a movie or video from a Chrome tab.

You can also set up a new Cast device, as well as manage existing ones, such as being able to reboot or factory reset right from Chrome. You can also rename your device and change the time options (time zone and time format), as well as change the language.

The Google Chromecast is a very versatile streaming device with lots of potential, and this is just what you can do with using a simple browser tab. On top of that, you can also customize your Chromecast with custom wallpapers, so we’re definitely looking forward to seeing what else this little $35 gadget can do in future updates.

Meanwhile, keep checking back as we continue to explore and demonstrate its value and please remember to leave feedback in the discussion forum and tell us what you think.
