Hi ,

mind to share what type of screen you've ordered through ebay? Cost? DIY type?

Thanks

He! He! So... do remember me...

We all ordered DIY from Ebay. So called cheap unless yo have jalan to find BOC here in Malaysia. If got, let us know where to get also.

SSF selling 3 layered BOC white blck white at around RM58 per me. The width is around 58". So, after framing, you might only get around 54 or less.

Max screen size you can go with that is around 110"

How's the quality of the DIY from Ebay? Because sometime cheap DIY thing do come with good quality

I've read through the Ebay , and fond that their DIY screen material is matte white. However, most of the screen I've seen in the Hi-Fi shop are light grey color. What's the main different between grey and white screen?

Thanks.

I ordered a "Matte White" Projection Screen Material from ebay. Its basically a synthetic material that is coated with a "Rubberised" material on the backside. The description of the item is NOT accurate, it is NOT Matt White" and it is NOT canvas. The synthetic cloth has a very slight silvery finish giving it a gain of more than 1. My screen size is 110" 16:9, that measures 54" x 96". Cost... check ebaylah, I bought material size of 60" x 112". I then DIYed a frame and installed the screen material myself. Very simple, the whole process takes less than half a day. For the material itself and the ease of installation, I have no complains. The material is easy to stretch and install to get a totally flat screen without any folds visible. Looks really professional if I do say so myself.

I cannot report on the quality of the porjected image on this screen yet, as I have not connected my projector. But pics from bro Tims setup shows that there is very slight hot spotting, but to be fair this may only be visible when photographed..... I'll post a review and pics later once everything is properly setup and calibrated.

The reason why hifi shops prefer grey screens..... Coz it helps them sell projectors

1. See, the viewing rooms in the shops usually cannot go totally dark. And if there are other light sources in the room, it will be reflected off the screen and then customer can see it, it becomes very distracting. With a grey screen the reflection is not so visible.

2. Another point is that the grey screen helps darken the blacks and also improve the colour contrast from the projector. So a not so good projector may perform better on a grey screen and persuade the buyer to part with his cash.

So if your room is not totally light controlled and if your projector needs help with the blacks and contrast then I suggest that u find a grey screen which has a gain of 1 or less than 1. But I prefer white screens coz the colour of white and true colour fidelity is equally important to me. Have you seen the colour of white on a grey screen..... well here's a hint...... its not white anymore.

Hope this helps.

Jason

Screen installation.....

The frame of the screen waiting for installation.


The package from US containing the Screen material.


This shows the rear of the screen its a ruberrised material quite thick and heavy. Even though the material is folded when laid out and lightly stretched, no folds ot creases are visible. Good stuff


Finallym this is the viewing side of the material. The pic is a bit dart, but there is a silvery finish to the material.


Jason

Here are some tools you will need for the screen materials installation... Upholstery stapler gun, screw driver and measuring tape.


Although my screen frame was origininally a solid piece of ply wood, I decided to cut out the centers to reduce the weight of the whole contraption. It will make it easier to hang it up and take it down in the future.

So what I did now was to lay out the screen material on the floor, using a large piece of cloth to protect it from the dust on the floor. Viewing side wodn, rear side facing up. The I lay the frame on top of the screen.


I start on the short side... just hold one of the sides down with ur hand and weights/remote controls....


And start stapling, no stretching yet...


Next go to the opposite end. Now I start stretching and stapling. The strecthing done here will remove any folds and creases.


Continue this process for the long sides and you will get a completed screen. Then entire process took me no more than 2 hrs. Would have been faster with another pair of hands.


A closer look at one of the corners...


Jason

And now to the cabling....

First Off, Bro Tim, I did not have very much left over, You are welcome to it if you think you can use it. I estimate that I have less than 10 feet left.

For my setup, I will admit that cabling is the most tedious and tiring part of the build. Why u ask?.... Since I wanted everything hidden, I had to pull the cabling thru, behind, under, between the walls and cabinets. Lets count:
- receiver to projector composite video x 3 DIYed using RG6/U and Neutrik shielded rca
- surround back left and right x 2 using cables supplied by manufacturer
- surround left and right x 2 using Accoustic Research 12awg
- surround front left and right x 2 using Accoustic Research 12awg
- center top and bottom x 2 using 14awg common speaker able
- subwoofer x 1 DIYed using RG6/U and Neutrik shielded rca
- interconnects between DVD and Receiver x 6 (3 composite, 2 analog L & R sound, 1 S/PDIF

Thats a total of 18 cables that had to be cut, spliced, soldered fed thru cubby holes..... Tokk me about 18hrs work to do this.... I kid you not!!

Just a note, the 12AWG and 14AWG cables are THICK. And its a real hassle working with THICK cables. So if you are not anal about thes things go with a 16/18AWG cable. I made allowances for hidden cabling, but in some spots the space just was not enough for 6 sets of thick cables to go thru.


Here are the Neutrik Shielded RCA Interconnects from Mouser. You'll have to take my word for it since you can't see it clearly thru the packaging.


Seriosly damaged packaging containing the 3 reels of Accoustic Research 12 AWG speaker cables.


Postage cost the sender US95.05, but I was only charged US48.00


Suprisingly the cables were not damaged on bit.... see not even a scratch.


Comes with the connector pins.... that I did not use...


Leftover Accoustic Research Cables...


Cabling hidden behind specially designed recesses just below the screen...


I will take the final pics of the competed room once the sofa is in place. I did not visit Harvey Norman as I found other alternatives for my furniture requirements...
