Francis hing, i tested on the link you gave me. If within the angle of 30 ( SMPTE recommended ). I can go up to 127 inch. And when i check the verticial angle, it recommended with in 15 degrees. Sorry my math isnt good , forgot how to find out. If viewing distance is 17 ft , and within the 15 degrees upward for verticial. So how tall is from 0 degree to 15 degrees?

Ok will go to the shops to see see.
Ac hing, for 92 inch do you think it's a bit small or it's right size ?
