My leaning at this budget, circa £5-6K, would be the Epson LS10500, but is that the right way to go? I would primarily be using for movies (BluRay & Netflix) and PC (+ some console) gaming, so the input lag would be a factor for sure. I'd ruled out older JVC models because of this, but they seem to have resolved this with the newer models. The laser of the Epson is great in so far as it negates the need to worry about changing a bulb, but are there performance features in any of the JVC or Sony 4K projectors that trump this and justify choosing one over the Epson? I don't know if I will be losing out with the 4K up-scaling of the Espon vs native 4K that some of the JVC and Sony projectors offer, but from what I've read I'd be somewhat hard pressed to notice? I plan to be using on a 100" screen and will be in a bat cave environment that is approx 4.5m long. I am not locked in to an exact seating position yet, so that's flexible. Any advice would be appreciated.
