toytoy, you are right. With RM800, can get Draper's Luma 92" pull down screen in HDTV format (16:9).

106" pull down is abt RM860. Fixed is abt RM3-4K. Electric is almost double the price of pull down.

Yes, fixed screen is very expensive, which make it non-viable for us. How abt DIY (sending to photo frame shop to do it) like rx330?

Thanks for the price htkaki. DIY is a good idea. But wat material to use? Any cloth can do? I m thinking of getting a plywood or something smooth and paint it with white/gray paint hehe. Can get a lot of paint mixtures online that's suitable for PJs but dunno where to start lah.

Actually my living room wall is a little little bit greyish already. But problem is wall not smooth. Will the rough surface of the wall be very very obvious if i just project the image on the wall itself?

Thanks rx330, i'll try to look around for cheap cheap screen materials hehe. Must it be cloth? I've just got an idea but dunno feasible or not keke.

It will be expensive to get a big piece of wood that is 64"x96" right? So can i use plaster ceiling board? I can ask the plaster ceiling contractor to help right? They can fix a few boards together to get the size i want and I just frame it up or something lah. Then can hang on the wall ma. They can make the surface very very smooth wan right? hehe. Is it workable ar?

But end of the day i still think its a bit weird to have a fixed screen on the living room. I m thinking of having a retractable screen so that i can hide a LCD TV behind the screen or something. When not using PJ can still watch LCD TV, if wan to use PJ just pull the screen down. hehe

But this will be very expensive ler. Sigh, such dilemma lah. sad.gif

pull down screen still consider 'affordable'. For me, if got really ideal room, I wld go for DIY fixed screen. No point splurging on branded fixed screen that costs a bomb

Besides wood, you can also try to DIY the frame using pvc pipes?

Just that you need to think of the finishing (side linings) once you're done as the cloth is wrapping around the frame.

I've built my own 8' x 4' plywood screen and hang it on the wall.

Going to paint it with matt white murobond paint and primer. Let's hope the result is acceptable. Total cost for plywood, wood frame, brackets, nails, paint = RM180 Verifed that the paint is really matt and don't have hot spots.

The screen goo paint pricing is simply ridiculous i.e. Rm1100 for a 1 litre set of digital grey and base coat!

I also pulled my own cables thru plaster ceiling for HDMI, composite and power. Will pull ethernet cable from upstairs switch later. Got local handyman to install ceiling manhole so that can pull other cables if needed.

Very sharp eyes tongue.gif Yes, it might cause reflection due to the brightness of the projector beaming forward. Unless he use fabric or curtain to cover it up.

A very good start to DIY screen. Cant wait to see the final result.

painting needs skill. I am one of the lousy fella in this.

No doubt cloth would be a better choice. We shall see the development of this.

yes, the bottom of the screen is 35" high coz my front speakers are 33" tall. ideally, the bottom edge should be about 18" lower but the speakers will get in the way; anyway will try it out first and see if its comfortable or not.

painting can be trickier than putting up cloth but its made a lot easier using rollers.
