Nexus 4 Output to TV via HDMI: SlimPort Review

One of the great features on the Nexus 4 is the ability to show your phone’s display on a big screen.

There are actually two cool ways to do this, one is via a cable, and the other is over WiFi using Miracast. The latter is more expensive, uses more power and right now doesn’t seem too easy to find compatible devices to beam to. No doubt I will get it going in the future but for now I decided to try out SlimPort.

I’m afraid this one is for Nexus 4 owners only, this won’t work on the Nexus 7 tablet. I also don’t see SlimPort listed on the Nexus 10 spec sheet but please let me know if it is compatible.

What is SlimPort?

SlimPort branded products use the Mobility DisplayPort standard to display HD quality images on your big screen television. A SlimPort cable is compatible with any enabled micro USB port such as the one found on the Nexus 4 mobile phone.

SlimPort boasts the following advantages:

  • Display Hi Res images up to 4K x 2K at 60Hz
  • Low power consumption
  • Ability to charge whilst viewing
  • Available with HDMI, VGA and HDTV connectors

Review – SlimPort on the Nexus 4

Using the SlimPort cable on the Nexus 4 couldn’t be easier.

  • Plug the SlimPort cable  into the phone
  • If using the HDMI version like me, you then plug your Television’s HDMI cable into the SlimPort adapter.
  • Change your Television’s source to the appropriate HDMI port.
  • Switch on your Nexus 4 and your display will appear simultaneously on the TV and phone’s screen.

The quality of the SlimPort image on the screen was very crisp and clear,  and when it comes to viewing streaming video it seemed only limited by the app being used.  Below are two demos I took, apologies for the less than ideal quality, but hey, this is an amateur blog – whadya expect!

But seriously, I hope you can see that the TV catchup streaming video actually looked good and sitting back on the sofa it was as clear as any image I normally get on my TV.  The iPlayer stream was blocky, but this has always seemed to be a problem with streaming to the BBC’s Android app.   It was watchable but slightly depressing that a decent picture was unavailable.  I’ll be sticking to my Raspberry Pi for iPlayer viewing!

Here are the demos, apologies that the sound didn’t come through, it is there but my camera didn’t seem to pick it up very well.

  • TV Catchup on a 32″ Samsung Series 5 TV via a Nexus 4 Phone.  This looked great, clear and crisp and a nice high resolution.

  • And iPlayer via a SlimPort cable and Nexus 4 Phone.  This on the other hand didn’t look so good, somewhat blocky.

Like the battery pack I discussed in my last post, this is perhaps not something I will be using regularly but will be a neat little gadget to have up my sleeve when I want to show some footage on the big screen.  It could be useful when stuck in a hotel with free WiFi but no decent TV stations, or for showing video footage shot

You can buy the SlimPort from Amazon.co.uk

Google Play Sound Search

Google Sound Search

Here’s a neat little widget from Google Play, a new addition to the Play app line up: Sound Search.

You might already be familiar with music recognition apps such as Shazam or SoundHound – this is Google’s version.

The idea is that if you are out and about and hear a tune that you really like but don’t know what it is, you can pull out your phone, tap the “What’s this song?” button on your home screen and a few seconds later you’ll be told just what it is!

How to Install Sound Search

  • Go grab the app from the Play Store
  • The app is a widget, so head to your app folder and select widgets
  • The app is listed as “Sound Search” so don’t make the mistake I made by trying to search in amongst the Google prefixed widgets!
  • The widget can also be added to your lock screen, so you don’t even need to unlock when seeking out a new tune.

Sound Search Features

The new Google Play Sound Search app doesn’t seem to feature rich as some of the other music recognition apps, it also appeared to be fairly slow in recognising tunes (but I must admit I have not done an objective like for like comparison).  Some of the more obscure tracks I tested with weren’t recognised.

On the plus side, the app integrates with the rest of the Google Play ecosystem so once recognised you can quickly make a purchase and add the music to your Play Music account for future listens.  It’s all very quick and seamless.

The app also stores a history of matches, useful for reviewing at a later date when you are looking for inspiration.

Portable External Battery Chargers for Nexus Tablet and Phones

Charging a Nexus 4 with an Anker Astro

Charging a Nexus 4

Our smartphones and tablets have become integral parts of our everyday life, but this has meant we are forever monitoring battery usage and making sure we are never too far away form a power plug. If you’ve ever found yourself worrying about your remaining battery charge then this post could solve that problem.

Having recently got caught short I looked into what options there were for portable emergency back up power supplies, and after some investigation I ended up buying the Anker Astro 3E.

This post gives a brief overview of how a backup battery pack might be a life saver, and why I would recommend the Anker unit to others.

What is a Portable Battery Pack?

A backup portable battery pack allows you to get some additional power once your Nexus’s own battery has given up on you.

The idea is simple enough, your tablet or phone runs out of juice and you can’t get yourself to a power socket. No problem, just plug your device into the portable power pack using a standard USB connector and you’re good to go. Your phone or tablet will begin charging and is, as usual, fully functional whilst powering up.

I don’t expect this to be something that I use regularly and I won’t be carrying around a battery pack on my daily commute. However, if travelling on a longer journey or heading to a weekend festival then this device is clearly an absolute must.

It’s not something that’s going to be used regularly, but when it is needed, boy am I going to be grateful that I have it with me!

Anker Astro Review

There are several external battery pack options available and they generally seem to do the same thing.  The only real choice seems to be the units capacity, after that you just need to make sure it’s compatible.

I ended up going for the Anker Astro external battery as it was clearly powerful enough to charge my Nexus, it was available on Amazon and the price seemed reasonable.  The Astro also allows for two devices to be charged simultaneously, although I can’t see this being the most useful facility right now, but maybe one day it will prove useful!

The pack is fairly chunky, especially when compared to the Nexus 4, and it’s heavier than I expected. So it really isn’t something you are going to slip into your pocket as an everyday backup. But if you pack it in a bag on your travels then you’re really not going to notice it in amongst your other clutter.

Charging times are impressive, the pack has a 3A output so has the grunt to supply all the power needed. Whilst writing this I’ve done a quick test of charging up my Nexus 4. I’ve plugged it in at 50% and it’s taken just over half an hour to get to 75%. So a full charge is going to be a few hours which certainly meets my expectations.  The Anker works fine with my Nexus 7, and although I can’t test it, it should be fine with the Nexus 10 too.

Charging up the Anker itself is going to be a case of plugging it into a standard USB charger and leaving it on overnight.  With a 10000mAh capacity the pack promises around 6 charges of the average smart phone. I’ve done three full charges and the capacity indicator lights tell me that it’s still half full, so I guess we’re on track to meet that prediction!

The Anker’s two ports are “optimised” for either Android or iOS, although it isn’t clear to me what the difference is. Either way, both ports can charge both types of devices.

Unfortunately I’ve just checked back at Amazon.co.uk and the Astro is currently marked as unavailable (although do click through and check!), and it doesn’t seem readily available elsewhere. However there is a smaller model which should be well worth a look and still good for a few emergency charges.   Some related products are listed below.

US buyers can still get the Astro 3E from Amazon.com
