Perhaps the single most important achievement of the EN4K fabric as far as we're concerned, though, is the way it avoids moire noise. With numerous other acoustically transparent screens we've had occasion to spend time with over the years, including some quite expensive ones, we've noted the appearance of shimmering, wavy line noise, especially over areas of fine detail. This occurs when a screen fabric's perforation step or weave size gets too close to the step size of the columns and rows in the source picture, so the EN4K's total freedom from such nasty artefacts proves again just how phenomenally 'solid' and fine its weave pattern is.
In fact, while we not surprisingly failed to find any 4k2k-resolution sources to try on the screen, from our experience with straight HD and simply looking at the fabric using a magnifying glass, we have no reason to doubt the veracity of Screen Excellence's claim that the EN4K fabric is entirely suitable for the 4k2k world if and when it arrives.
While this is all great news for the EN4K's picture quality, though, it does raise major concerns about the fabric's acoustic properties. For surely a fabric as dense as this can't really also let sound through, can it?
Actually, somehow it can. In fact, once we'd got used to the idea that a highly affordable acoustic fabric could produce a picture quality almost as satisfying as that of our much more expensive, non-acoustically transparent reference screen, the EN4K's ability to let audio through became our single favourite thing about it. Only during extremely quiet scenes could our reasonably sensitive ears detect even the slightest hint of volume loss. And there didn't seem to be any reduction in clarity at all.
So is there anything that we don't completely love about Screen Excellence's really rather inspired EN4K fabric? Well, if pushed hard we might say that while the reduction in brightness caused by its acoustic perforations doesn't trouble us much at all with 2D viewing, it does seem more noticeable when viewing active 3D sources. So effectively, it slightly exaggerates the inevitable brightness loss you get as soon as you don a pair of active 3D glasses. Or maybe it would be better to say that active shutter glasses exaggerate the slight brightness loss associated with the EN4K's acoustic transparency!
However you describe the brightness reduction when watching 3D on the EN4K fabric, the only thing that really matters is that it is far too minor a flaw to be remotely considered a deal breaker. After all, this single niggle is completely and utterly overwhelmed by the quite remarkable amount the EN4k fabric gets right for what is, in the circumstances, amazingly little money.
