Setup, Testing and Image Quality
We set up the Nexus 4 first with our SlimPort HDMI adapter, and all that is required is to simply plug it into the microUSB port on the Nexus 4, and then plug your HDMI cable into the SlimPort HDMI adapter and voila - it works.
You could not ask for much more than that, and I'm a huge fan of pure simplicity. The easier it is to setup, the more mainstream this technology will become. I'll write a little about the quality, but it's hard to capture great images, or video, without losing quality.
The SlimPort HDMI adapter is simple as pie to setup, just plug your smartphone up to your TV and it just... works. The one thing I noticed instantly was how smooth it reacted on the TV from the Nexus 4. There was no lag, which I thought there would be, or at least some - it's an instantaneous communication between the N4 and your TV.
I could stop my review there, because the SlimPort HDMI adapter just works, as it says it should. It's a couple of seconds, tops, before you're up and running. There's even a spare microUSB port on the adapter itself, which you can plug a charger into it. This is a key part of its use, as you can keep your device charging, while it's outputting something to a TV, since of course the SlimPort is taking up the charging port on your supported device.
This means you could use Analogix's SlimPort HDMI adapter for business meetings, where you might keep a video, or document on your device, plug it up and have it playing, all while it's charging at the same time. Beautiful.
Picture quality on the SlimPort HDMI adapter is nothing short of perfection - TweakTown looks quite stunning on a 55-inch Samsung LED TV.
Let's move onto the MHL-based Galaxy S III accessories that we have for comparison sakes. First off, I have a Samsung Smart TV that I had the joy to plug this into, so luckily I had a MHL connector on the TV to play with. Without that, we'd not even be talking about the MHL cables we have here today. Plugging the MHL cable and the S III into a non-MHL HDMI port didn't even detect the port had anything plugged into it, but moving it into the MHL port worked a treat and away we go.
Ok, yeah. That's what the difference is. The supplied MHL-capable cables for the Galaxy S III were connected in, and there was a difference. It's not a huge difference, but the colors on the SlimPort tech are much better, and the picture is sharper and more defined.
There was a nice difference in terms of portrait and landscape use, which the MHL cable went directly into portrait mode (how you would use your phone) and I needed to go into Settings and change it to auto-rotate, and we were fine once again. But the quality is no match for Analogix's SlimPort, which is beautiful - no lag, perfect picture quality, and is instantly visible to be the superior product.
Considering MHL is meant to be 'Mobile High-Definition Link', I didn't feel like I was receiving a high-definition experience. It felt very subpar, and the SlimPort product felt like I was receiving the gold class cable experience, period.
