Hi, I would describe the cloth as dark grey. I have the frameless version. You can't see anything of the tensioning frame as the fabric completely encloses it and is attached to the back.
This item (AR120H-CLR) can be hung as a picture.
In this video, the assembly and hanging are shown: https://www.youtube.com/watch?v=DpQ7QvRUnVY&t=333s.
It has a wall bracket with sliding option to align the screen in an optimal and easy way.
Probably because the can't make bigger screens cheaper...
Check this video (starting 1:10), this might help you understand :)

Due to different suppliers and delivery conditions, there may be price differences compared to other suppliers and to the manufacturer. We always try to set a price in line with the market, but this is not possible for all products.
Unfortunately, it is impossible for us to tell you. Prices are based on supply and demand, suppliers and availability of goods. Therefore, prices vary very regularly.
Due to different purchasing conditions and changing suppliers over a certain period of time, price changes/fluctuations may occur. We generally work with daily prices.
This screen is really excellent for short-distance projectors and will also work with the Allegro. However, the set-up is a bit tricky and should be done with the utmost care. Every little "hiccup" or unevenness will be visible in the picture later. In addition, the beamer must be aligned very precisely and ideally also fixed, as the image shifts with the slightest change.
