3000:1 Image Contrast Ratio

The above distinction ratio ensures that black will appear darker while white will seem whitish. The tip profit is that you’ll get an in depth view which is essential, particularly for players – it allows them to see impending obstacles and overcome them easily.

Digital correction may not work in gaming modes either, for some projector fashions.
