A large query that employs almost all projector owners is whether it affects the image of our projector screen.
The truth is that this is a complex question more in essence the answer is simple. Let’s try to say two logakia thereof and make ourselves understood.
Modern headlamps are equipped with all the necessary sliders so they can deliver the right temperature white and great precision in color palette when D65 standard after an appropriate setting.
The screen, across the projection process plays the role of mirror. That is in essence reflects the image that sends more of our projector.
Due to the wide range of regulatory of modern projector, we can get white and colour fidelity even if the screen is not 100% white. If BC or our screen blush, then we can very simply to reduce proportionally the red in RGB setting of our projector, to increase the blue and green in the same buffer and get a 100% pure white as we would get to 100% white screen (with our regulatory position in the relevant course)
That is, in other words we will not see a different image to display different tint (to clarify that we are talking about small deviations of white or grey and not excesses with colored screens) after the projector may like Chameleon (via regulatory) fits within the relevant data, so in essence all the screens that appear white or gray in our eye , is fine and will perform the exact same image if our projector properly adjusted for the individual every time.
This is the first myth debunked …
Go now in reflection of our screen, the familiar gain. There we heard at times, gray with gain 0.8 improves the black and high 1.3 e.g. our brightness increases. Yes it is true … but..
When we display on screen with low glare index (gain) then Yes, we have better black other in parallel and have lower light. I.e. our profit in contrast is 0. Respectively and in high gain.
Example to understand ….
If e.g. the projector leads 100 nits white and 1 black nits in white screen, then to a gray screen with half reflection will take like 50 count white nits and 0.5 nits black respectively. I.e. the contrast of the image remains the same (100:1 = 100 and 50:0.5 = 100). I.e. in essence you won’t see better contrast than the same.
The second myth debunked … high contrast screens that succeed best black while retaining the brightness or vice versa.
Of course there is a possibility to get improved contrast, with a high gain other gray color. With this type of screen we can achieve a reduction of reflections in the field, since due to high gain “collects” all the light and sends it straight across and not in all directions as white with gain 1 and at the same time because grey not uploaded very black level. In this way, in essence, ‘ seeing ‘ better contrast. This for standard viewing areas, because in dark rooms that no reflections will get the same result, just using a white screen with a gain of 1.
Let us come now to our key question. What differences you see in the picture between a panakribis screen (e.g. Stewart) from a no name. Absolutely no! In both modern screens projectors can be configured to perform exactly the same image, regardless of the color, the material or workmanship of the screen. There are no magic sails and fabrics to improve our image. It’s simple math, if somewhere we win then surely somewhere else we lose.
The only difference between the screens actually exist, is the quality of the materials. That is an accurate display can keep more in time than a cheaper (the cheapest will do faster creases if going to flap or if it is fixed it will come faster wear on the cloth).
Of course there is also the matter of image … otherwise is to say, I give 5,000 euros to 150 euros anyway screen from ebay.
Conclusion, there’s no reason other than workmanlike, move to buy accurate monitor, you won’t see a better picture, this is just a myth and marketing firms. Better to give them the extra money to buy a better projector, there will definitely see a difference. As much difference (in contrast) we’ll see if we try to reduce the reflections of our space (curtains, painting with dark colors, etc.)
