Streaming video content/media of any kind from your Android smartphone or tablet to the big screen is great thanks to the Chromecast, but sometimes the resolution may not quite be what it's supposed to. A new root required application called second screen aims to fix this by letting users scale up the resolution from whatever device you're using to stream, so that it ca match the resolution of the television that you're streaming to. The app works with rooted devices only as stated, but it doesn't just support the scaling of resolution to TV's, it lets you select whether you're streaming to a TV or a monitor, and you can select whether it's a 720p or 1080p resolution.
The app in short takes your phone(or tablet's) display resolution and screen density and scales it up to match the larger screen. This ensures the best "big screen" experience possible if you were previously having resolution issues when streaming to your Chromecast device. There are also a host of other features included with the app here as well. Always on desktop mode within Chrome and the ability to show desktop sites in chrome by default are just a couple of the useful things that Second Screen can help you do. Streaming to the Chromecast can be a battery drainer sometimes which is why they have built in some nice little features to help you save as much battery life as you can.
You can turn off device backlight and vibration so you can save battery, and Second Screen also provides overscan support for older TV's. Although the developer mentions that this feature requires at least Android 4.3+ running on the device. The app itself however will work with devices running at least Android 4.2 and up. The only downside that we can see here so far is that the app is limited right now to only devices that are running AOSP based ROMs or Stock Android ROMs. If you're running anything else the dev says there's no guarantee that it'll work. That means however that it may work. So if you're inclined to try the app out you can do so and it on't hurt your pocketbook since the app is free. The paid version does offer a few extra features though so if everything ends up working out OK we'd suggest grabbing the paid version down the road.
