would rather not open 15" benq 567sv11 until fresnel problem has been resolved could anyone who has stripped this monitor tell me the dimensions to get the plate glass cut to or can i just measure the visible screen from outside ?
thank's

Let's something straight here, your waiting for pro fresnels to use on a 15" lcd? For a 15" lcd you can buy the standard lenses and be done with it, or wait on the pro lenses and use it with a 17" lcd for its 1280x1024 resolution.

Or am i missing something here?

The panel is 9.5" x 12.5". The visible area is 9" x 12".

If you are mounting the screen in its origional metal surround,the dimensions of that are: 326mm x 249m
Sorry,I only do mm's

thank's for quick answer's.
in answer to Sietski71 query,
have both LL lenses, purchased zoom first with the problem fresnel,then ordinary kit to do as you suggest,but here in uk it's not that easy to find part's, LL sending light kit if testing ok for uk 240v system, if i have all the proj parts before fresnel problem is resolved and i build with ord lens, can i just make another focusing box to house the zoom with the 15" panel.
comment's appreciated.
