I hope you will find this Optoma UHD51ALV review helpful enough for your future purchases. I was very delighted to test this unit, as it has 4K True HD resolution and stunning 3D support. The colors are truly vivid and bright due to the brightness of 3000 lumens.
The bunch of the Optoma UHD51ALV specs makes everything to fulfill the picture with amazing crispness and details in every scene. It also has some smart options, such as voice control with Alexa or Google Assistant. So my point is that this one is actually one of the best projectors for a flat rendering of 4K reality and fabulous 3D projection.
