I wish you much happiness with your setup, but be honest and let us know how happy you are with that system in the long run 》 ofcourse we want an update !
I'm back. Ambivision arrived a week ago and I can finally make an update now that it is 90% calibrated. Long story short, it's just outstanding although it has its flaws.
It's been a nightmare to calibrate. It has values that need to be calibrated both on how the camera sees the screen, and after that, how the colors are reproduced in the led strip.
There's R G and B gain values for the camera as well as an auto camera gain range which adjusts how the camera captures the screen depending on how bright the content is.
On the led strip side, there's gamma correction, saturation correction and color curves for every channel. Leds are addressed individually much like hyperion and unlike Philips, whose gradient led strip has several sections of 10 leds each, which look ugly to me. In the app it's mandatory to set how many leds are laying in every side of the TV, like hyperion I believe? it doesn't get any more precise than this.
One of my major concers, which was latency, vanished the first day. There's no latency, not even with at 30% smoothing effect, which is more than needed for a fluid performance. Even at 100% there's not much latency and at 0% there's no flickering, so all in all, zero problems with that.
On top of that, it has an API with which I can easily control the led strip through Node Red. It has been integrated in my smart home seamlessly.
It has a beautiful effect perhaps due to the camera setup? Playing Death Strading for example, when an image with a very bright sky on the top half is displayed and dim grass in the top bottom, the led strip only represents the top half with a beautiful pure white. Hoever if you turn down the camera so you don't see the sky and see only grass, suddenly it represents the grass with a beatiful dim yellowish green. You go back up, and the dim green dissapears. It's beatiful because it behaves just like the human eye.
Now the cons. The app crashes a lot, there's a lot to improve in the whole system since every now and then certain settings go back to default and I need to open to app to readjust them (thankfully color calibration stays intact. Only smoothing and some other minor things). Support sucks, you have to figure out yourself almost everything. I hope it keeps up in the long run?
So, concluding, and I hope I don't get much hate, I can only thing of one reason I would go the hyperion route and that is color accuracy. I believe with Ambivision it's just not possible to get a 100% absolute perfect color accuracy given how the system works. I do believe that's feasible with hyperion although I have found just one guy in this forum who has been able to achieve that with hyperion. However, when looking at the screen, 90% color accuracy feels like a 100%. For the rest, IMHO Ambivision just outweights Hyperion by far. (CEC,HDR,4K,FHD,HDR10,TV shows, TV sports, infinite inputs, built in TV apps, etc...)
However, I understand you guys going this route instead of Philips, I definetely share that.
Porbably in the future I'll give hyperion a go in smaller project. Maybe for the kids console or something of the like, because I'd really really love to delve into it and get 100% perfect color accuracy.
