So I was having what I thought was an unrelated issue, but now seems related lol.
I have a BenQ w1070 paired with a 120" Aeon Zero Edge with CineGrey 3D. I had been having an issue where either the projected image or the screen was not 16:9. The projected image when lined up perfectly with the top and bottom of the velvet border would not reach the velvet border on the left and right. There was at least an inch gap on either side. Didn't have that issue with my 110" screen that I replaced. Very maddening.
I had been in contact with both BenQ and Elite support trying to find out what the issue was. BenQ was going to RMA the projector. I was hesitant because I wasn't sure it was hardware related. The BenQ rep asked me to measure the viewing area and the projected image to see. I measured the screen itself and the viewable area within the border and it was 16:9. Measured the projected image and it was a bit off, but that could be chalked up to some extent with error in measuring, and in any event was nowhere near enough to be a full inch short on each side. So I checked the Elite site for the dimensions of the screen just to see if there was something amiss. When I measured the screen I got approximately 104 and 3/4" wide and slightly over 59" tall. The dimensions on Elite were 104.9" x 59.1, so no issue there. The viewable area was another matter. It was a lot shorter than what Elite listed. I then saw that they had the velvet border listed at 10mm. 10mm converts to about .4 inches. The velvet border that I actually had on the screen was way bigger than that. It was almost 1.5" thick so more like 30mm.
I told Elite support about this and they didn't know why the velvet tape wasn't 10mm, but said that he checked and that they all are the same size as what I had. Now I still had no reason to think that this made any difference in my situation, as I applied the border perfectly straight using the frame as a guide and when I measured it in many areas across the screen, it always measured the same everywhere. I just had a nagging sense I should take it off anyway. Elite said they would ship me more velvet tape, so I decided to remove the tape that was on the screen. I figured, worst case, if I couldn't get the glue residue off the screen, I would just cover it with the replacement tape. To my surprise, the tape came off rather easily, and the glue residue came off completely with a microfiber cloth dipped into a bowl of hot water and dish washing liquid.
I hung the frame back up, zoomed out, and lo and behold, the projected image fit perfectly. No gap on the sides anymore. A perfectly straight 16:9 image. I was ecstatic since I never really wanted the border on anyway, I did it fearing I would need it to hide slight issues with the projected image that would be very noticeable otherwise on an edgeless screen. I am finally enjoying my screen without any issues and I love it.
That got me to thinking. It makes sense that the border was the issue. The projected image is 16:9. That means that the width is almost double the height. When you apply the velvet border, you are reducing the viewable area by the same number across the screen when you really should be reducing the width by almost twice as much as you reduced the height. For instance a 100" diagonal screen measures 87" in width and 49.5" in height. If I made a screen that was 86" in width and 48.5" in height, is that a 16:9 screen? No it isn't. I reduced the width and height by the same measure (1 inch) and the screen was no longer 16:9. That's what the velvet tape is doing.
The tape is different than bezel. The tape is applied to the actual viewable area of the screen and should be taken into consideration. Bezel is outside of the viewable area and makes no difference how thick they want to make it or whether it needs to factor into 16:9.
Bottom line, don't use the velvet border lol. It looks great edgeless anyway.
I have contacted Elite support again about this and told them my findings and they are looking into it.
