All parameters
Brightness (lumens)
4000 ANSI
The brightness of the projector bulb in ANSI lumens units. This is an important indicator if you want to use the projector in daylight conditions or lit rooms. A higher number of lumens means better brightness. Dateks.lv recommends to buy a projector with 2000 and more lumens.
Contrast ratio
3000000:1
The projector contrast determines the sharpness of the image. The higher the contract the clearer the visibility of the text on the screen; the contrast also determines how well the lines will be pronounced in the image created by the projector. A high contrast is an important factor when a projector for the presentation needs is selected.
The measuring unit of the contrast is the ratio between the lightest and darkest condition of the pixel. The higher the ration the better the contrast.
The measuring unit of the contrast is the ratio between the lightest and darkest condition of the pixel. The higher the ration the better the contrast.
Native resolution
4K 3840 x 2160
The matrix (natural) resolution determines the number of colour dots (pixels) the projector can display without compression (at the maximum sharpness of the image). The higher the matrix resolution the better the sharpness of the image and the bigger the software desktop for efficient work.
