“With good 4K source material, the Optoma UHD4K clearly has better detail and sharpness. It also has the benefit of almost no visible pixels lines or screen door effect.”

“…Optoma was able to reproduce detail in the star field that the Epson simply could not. We concluded that this was a very good image to show the difference between 4K e-shift which is 4 million pixels vs. the Optoma with its 8 million pixels delivered to the screen. You can clearly see many, many stars that are just not visible on the Epson.”
