    I am getting very frustrated with trying to find a reasonable quality screen. :suicide:

    Does anyone make a screen that does not have ripples in it and is the correct size/ratio.

    Owl screens seem to also suffer the problems I am experiencing from the 2 Ellie screens I have had to date. The main problem, the same also with my Draper Luma, is that when measureing the white area of the screen its not true 16:9 and therefore the image overlaps at one end!! eg 244 x 138 and should be 244 x 137

    I know there are tollerances but +/- 2-3 CM is a little off.

    Now before you accuse my projector, Epson TW100, its spot on as I measured the pattern image tonight on the wall and it was 244 x 137 CM which is 16:9

    I can't believe that I have to pay £2000 - £3500 for a screen.

    I would be very gratefull if you guys would check you screens and let me know if they are correct and what make.

    Thanks

    Peter

    Just measured my Nexnix for you - it's 180 x 100.7 cm - by my calculations, for true 16:9 it should be 180 x 101.25, so the height is off by half a cm.

    Just what I thought Godfather. So you probably have some overlap or underlap depending on how it is set up.

    I think, but not 100% sure that Nexnix screens are made by the same company as Ellie and Owl :(

    All I can sate M8 is that you must be not a fussy as me and just put up with it - not trying to be funny

    Well until you find an affordable alternative then I guess I'll have to put up with it or go back to my RPTV. I'll probably get a Stewart next year so this screen should keep me going until then. It's my first projector so I'm still learning.

    It does bother me a little, but no where near as much as say edge enhancement! Half the films I watch have aspect ratios of 2.35:1 so any overscan is not really an issue. Even 1.85:1 material is fine. It's only 1.78:1 material which overspills onto the bottom black border and 5mm from 12 feet away is just about acceptable to my eyes. I'm far more fussy about the actual image quality and have spent many hours (more like days) adjusting the RGB gain values in the service menu in an attempt to achieve a perfect grey scale. I'm still not quite there so Gordon will hopefully be coming over next week to ISF calibrate it. May be after I've got the image perfect then I'll shift my focus onto the screen.

    Good luck in your search for the perfect screen. Let me know when you find it!

    You should be able to get a Vutec Lectric I screen in the size you desire with VuFLex Pro fabric (which will hang flat) for under the £2,000 mark, mainly because it doesn't need tab-tensioing to hang flat which adds a fair bit to screen costs.

    Size tolerances are to 1/4" (6.4mm) and you can have any custom size you want. Gordon (and many other dealers) will be able to help you if you are interested.

    Is 5mm an acceptable amount in the industry then ReTrO?

    And, what's the correct size W x H in mm for a 6 foot screen like mine?

    I say tolerances, in reality it's the closest that we can spec the dimensions for the viewing area of the screen. In reality the actual area is pretty much spot on to what we ask for, I think +/- 1 or 2 mm.

    Correct size therefore for a 6' wide 16:9 screen will be:

    72.00" x 40.50"

    +/- 2 mm is acceptable but NOT +/- 6 MM.

    For a £2000 screen i would not take the risk if I thought it could be 6 mm out :eek:

    Personnally I've not ever seen any wonky sided screens that would indicate measurements being out. And should it happen the screen/fabric can be swapped out.

    Just as a side note, the furniture I make at work has to be within 0.5mm +/- and thats pretty good for a 10ft dining table made from wood :)
