Hue TV 4+

The apps works, easy to setup. Minor input lags also as expected. I don't think it's possible to sync the lights to my TV via an apps without delay anyway.

The colour accuracy is affected by the TV's brightness and the iDevice's camera. If there is some setting to calibrate the camera, that will be much better.

e.g. When I set my TV to dim (in fact, very dim), the Hue can accurately reproduce the TV's colour. And if I set the TV to bright (normal TV brightness), the Hue colour will be lighter than the TV, because the camera fail to accurately capture the colour (the light actually match the exact colour shows on the iPad screen, just the camera cannot capture the colour accurately from a bright source)

Also, if I use my iPhone 6+ as the controller, the colour will be more accurate than my iPad 2. Very clear that the camera quality make the difference.

The apps provide few different settings. My recommendation is to use single colour, fast, and normal Vivi. This setting is closest to the native TV ambient light (I have the Philips TV that has build in ambient light as the reference).

To sum up, the apps cost virtually nothing if compared to the whole Hue setup. And it's worth to buy this app to release the true power of the Hue system.

It’s better if I can zoom in to my TV screen, and also hope it can compatible with new lightstrip plus. Coz now only two led is using, not three of it...
