Projector screen warping

Posted by: Flame on 29 June 2009

Hi guys;

I've had a DaLite pull down projector screen for about a year now and I've noticed that it started to warp/ripple. The deformity is mild at the current time and doesn't interfere with my viewing pleasure much. I guess that this will worsen with time and was wondering if there is anything I can do to "correct?" this rippling before I have to buy a new screen.

Regards...

Nothing to do. Except a DIY fix.
You should have bought a screen with tensing devices. More expensive but you now understand why.

Over and over I am convinced that one should by the most expensive option he could afford. Any DIY suggestions?

This might work to some extent but it will need tensioning evenly from the sides as well.
You would need to sew in pockets in the corners and insert 3 bracing rods - not very practical for a roll down screen.

Or you could attach bungee type tie off cords to the edge of the screen with end loops which secure from small dowels in the wall.

Sticky backed velcro.

Interesting.... Will hang a few bricks/shoes/cooking pots and see if that smoothens out things a bit Big Grin

A pair of goat-skin water bags, one at each bottom corner, and obviously filled with water.

I used to see these everywhere when I lived in the Trucial States so you should have no problem sourcing them. As the water slowly evaporates through the skins it cools, so you should be enable to switch off the aircon and also enjoy chilled water.

Better than a load of bricks/shoes etc.

But I recon you need to take Manu's advice and invest in a "proper" screen, unfortunately

A pre-tensioned screen is on my upcoming upgrade list. Many items on the list actually:

1- 1080p projector (when the current lamp on the optoma hd 65 dies)
2- DTS HD master audio capable AV receiver
3- a proper projector screen maybe a D-snap from Da Lite

Unfortunately, I think these upgrades will have to be pushed back as much as possible due to other major expenses in the coming 6 months or so.

For ideas to add tension to your screen sides, look at manufacturer's websites.

Unless it is mandatory in your decor, a pull down screen is to be avoided. A fix framed one is much less expensive and will last for ages.

Your screen is the equivalent of speakers in your audio system. Nobody will use cardboard enclosure loudspeakers. Do not cheap on the screen. Go with the best: Stewart Filmscreen, Screen Research, even the less expensive Drapper. It will cost you what? around 1500 US$, less than your floor carpet.

Another option is to use the wall and paint the projection area with specially formulated paint.
Although I don't know how good this is, has anyone tried it? I am thinking of getting some myself - I just use a white wall with decent results at the moment.
