Jeg hadde også litt bølger og skrukker i duken etter montering. Nå har det hengt på plass i to dager, og mesteparten av skrukkene er borte. Er forøvrig enig i dårlig passform, duken virker noe stor.
Jeg hadde også litt flekker på duken. Virker som de som pakker ikke vasker hendene spesielt ofte. Synd for AVshop som kommer til å få mye pes for dette. Jeg tok en fuktig klut og tørket av duken, det fungerte greit.


I can't see how these creases would disappear no matter how long it was up, they are more like folds at the corners; see (very bad iphone pic attached).

Adrian: Have you tried carefully and evenly distributed the screen fabric along the bars? I got the exact same thing with mine, but after making sure it was as even as possible I got rid of it almost completely, and it's still improving.

pseudo: Jeg har ProCurve ramme, og dermed ikke peil på stiftefrekvens.

Jeg monterte DIY duken min i dag. Tok ned den gamle V1 varianten, og stiftet på den nye V2 varianten.

Det var ikke noen feil, eller flekker på mitt lerret.
Samtidig var det enkelt å trekke den på rammen, da det er mer strekk i V2 duken.

Jeg har stiftet ca hver 10-12cm rundt det hele. Da sitter duken godt, og det er ikke antydning til skrukker eller ujevnheter.

Med andre ord er jeg meget fornøyd.

I've tried as much as I think is worth it. What the bad iphone pic doesn't show is that there are also bulges on the other corners too, just not as bad. It seems to me that the cloth is cut too large in one direction - if I pull the cloth further than the frame rebate that's holding the cloth normally allows, the problem disappears. It's just very bad sizing.

Add to this the slight thread damage close to the center of the screen, the staining and the creases (which btw, was caused by the cloth not being properly rolled up onto the packaging) and I can honestly say that even if the fit was perfect I'd still be asking for a new one. It looks like my cloth (and the bag it came in) were made by a child in a coal mine. I'm sure Avshop will agree when they get it back and examine it too.

It's very good to hear that it's possible to get good samples of this cloth as it really does look like an excellent material.

I unwrapped the V1 canvas that I have here and the grey side looked perfect with no stains or thread damage. The colour was a little dark and the weave is not as fine as V2 but I thought it would be worth a try. But that's as far as that thought went because unfortunately it's way too small to fit the frame.

I've now put on the original vinyl, non-acoustic material on the frame while I wait for the new V2 to arrive.

Har oppdatert V2 siden, med flere bilder. Dette ser ikke bra ut.... :(

Ettersom duken består av to lag som er limt sammen, må den stå under strekk en del uker før stofflagene "jevner seg ut".

Jeg har sett dette jevne seg ut over tid på en prototype, så det ordner seg nok! En annen ting en selvsagt alltid kan prøve, er forsiktig bruk av en føner. En kan også prøve å stramme opp duken litt mer, det vil også hjelpe...

Arrrrg!
Regner med at dette er en "test" i menneskers tålmodighet i fra Avshop sin side Er over 1,5 års siden jeg betalte for Ultra HD lerretet. Regnet ikke med, å måtte vente enda lenger med å få et feilfritt lerret. :)

Well, I really do hope I don't have to wait that long!

Posten just sent me an sms; the new canvas is waiting so I will get to check it out tonight. I'm not sure if I will fit it tonight though as the original vinyl screen looks ok and I still haven't watched a full movie on my new JVC HD550 yet just 5 minutes of dark knight last night to make sure the new room is cabled properly. (Surprisingly the sound is not that bad through the screen but I guess that's because we have it "floating" from a sloping ceiling with space between it and the walls and floor and that will change when the velvet curtains are finished and hung up.)

And a big kudos to AVShop for replacing the canvas so quickly and without any hassle. :)

Min duk har strekt seg fint i løpet av de siste dagene. Er fremdeles en liten skrukk i det ene hjørnet, men det er nok mest fordi duken ikke er jevnt fordelt på stengene. Blir bra til slutt! :)

Bilde er i alle fall svært bra, og lydgjennomgangen virker også veldig bra, så selve DUKEN er bare kos.

Da har den nye duken kommet!
Denne duken har ferdig sydd lærkant rundt lerretet.Her er det ingen muligheter til å klippe i duken under tilpassing. Duken ser noe snau ut, men det passer sikkert!
laster opp noen bilder senere i kveld :)

I've received the new V2 canvas too. No damage to the weave as far as our initial examination shows but there was some small damage/bad sewing to the leather that holds the metal rods - my wife had to undo some of the sewing and redo it (lucky I married a seamstress!)

There are a few very small stains which I guess will come out if we gently wipe them.

The fit is much better than the first V2; the size is still too big though and we had to use the "squeeze the fabric together along the length of the rods" to get a decent fit on the frame. Even so, I'd say that the canvas should be much more tight on the frame than it is.

There are quite a few creases in the canvas too. We have the screen face up on the floor now and my wife is streaming both the velvet frame (to get rid of the compression marks due to packing) and the canvas (to try to help remove the creases and hopefully to help tighten up the canvas). At least so far the method works wonders on the velvet - do not try at home unless you know what you're doing.

A few comments;

1) the way it's packed is not very good. The wooden plugs on the tube are nailed in and very difficult to remove without destroying the tube itself - not good if you need to use it to return a faulty canvas. Also, if one of those nails were to be overlooked and left in there when you were removing the canvas it could cause damage. At least my V1 didn't have those plugs nailed in - they were just held there with tape.

2) The plastic bag with the canvas in was dirty again, covered in a fine dust and it looks like that same dust is what causes the stains on the canvas. How difficult can it be to have a clean production area???

3) The creases on the canvas seem totally unnecessary to me. Most seem to have been caused by mishandling and bad packing.

As for now and unless I find a major fault in the canvas later tonight, I think I'm going to accept this one but if I'd known how much massaging this canvas would require I'd have opted for an SMX or other AT screen even if it had cost 2x the amount.

Again I have to praise the good customer service of AVShop which made having a faulty product much less of a pain than it could have been.

Alle gode ting er 3?...............

Well, here's an update; first, if anyone has a DreamScreen frame with any kind of velvet compression marks you should try very gently steaming the marks out and using another piece of velvet to brush the nap back into shape - it makes such a difference! The velvet goes from looking a little shoddy to a consistent deep inky black all over. My frame now looks just amazing.

The steaming didn't have such a profound effect on the canvas although I think it helped a little.

So, after spending some time configuring and tweaking - it's all an entirely new system - I sat down and watched the first 10 minutes of Dark Knight and some Kung Fu Panda. Still getting used to the different modes and lens apertures with my HD550 but my overall impression of this canvas is positive. I noticed that if there are large areas of moving white (for instance, a panning scene over white clouds) you can see some structure at 3.5m but only if you are focusing on the screen rather than the movie and it isn't really an issue in anything I saw last night. Maybe this is due to the creases in the material and will lessen when the canvas has hung for a while. The screen (grey side) was certainly bright enough with my HD550 at a 3.5m throw in normal lamp mode, cinema 1 and aperture 1 (although I preferred aperture 2).

I thought I would qualify my impressions a little as the entire environment will effect what I see; the side walls of my room are painted with a flat, relatively dark reddish terracotta to cut down on reflections without being too over the top. The (sloped) ceiling is stained wood panel so it's fairly non-reflective and the rear of the screen has been coated with the black Gerriet's Scenemolton felt to help limit light reflections back to the rear of the screen. Not a perfect room but certainly it will give better results than a white painted living room. ;)

After all of this I must admit to being more than a little curious about how much better the Screen Excellence 4K material is though... :)
