Thanks for the links.
If find it a bit confusing that both https://www.amazon.in/Punnkk-E7-Motorized-Projector-Screen/dp/B07GSZ8NYM and https://www.amazon.in/Punnkk-Motorized-Projector-Screen-Height/dp/B07J4X596P are listed as 7x5 ft but the aspect ration of the former is 4:3 and the latter is 16:9 ? Is it possible for the aspect ratio to be different when the dimensions remain the same? I have asked the seller to clarify but haven't heard anything yet.
The 9x5 ft screen is too large for my constraints.
