Adjusting Maximum Drop on a Panoview 92" Electric Screen

jagsta · 21-10-2009, 10:42 AM

I'm looking at upgrading my screen from the existing Tupplur blind i've got to a proper screen, 12V triggered from my HD20 projector. I've measured up and the default drop at maximum extent (30cm from the housing to the start of the screen) will be about 10cm too much to allow for a projected image without keystone correction.

I've read the manual for this screen (the model number is 9092EGA), and it refers to adjusting the maximum extent the screen lowers, but that this should be done by a dealer or professional. Surely it can't be so difficult that it can't be done yourself? Other screens in their range provide a bit more detail on how this is done but all say it should be done by a professional.

Has anyone any experience of adjusting these screens? Do I really need to get someone in to perform this part of the installation? It seems a bit of overkill to me.

If the advice is to get someone in, can anyone recommend an installer in the West Yorkshire area?

Would be very interested in how you get on? I have been pricing up PJ's and screens over the past few weeks and also decided on exactly the same. Optoma HD20 and the Panoview DE-9092EGA. A couple of questions for you.....Where did you go to get them? What distance is your PJ to the screen? Mine is 340cm.

I'm still looking for the best place to source the screen from, there are a lot of places which list it but are out of stock. I bought the projector from Superfi for 899.95, with which they gave me £80 of vouchers to use with them.

Confusing things slightly is the fact that there seem to be 2 part numbers listed on various different retailers for the screen - either DE-9092EGA or DE-9092EGS. I don't know if they are in fact exactly the same, so i've emailed Optoma UK for a definitive answer!

My projection distance is 360cm lens to screen, which with the HD20 gives me a minimum projection width of around 195 cm. This is just right for the Tupplur and will suit the Panoview well too.

- UPDATE - I just got a call back from Optoma UK, the EGS is an inferior screen, so it's the EGA I need to get.

The differences with the EGS include:
Lack of integral IR receiver
Lack of the L bracket adjustable mounting systen
2 layer screen instead of 4 layer

The guy also spoke to me about the Grey Wolf screens - I wondered if they were worth looking at due to the light colour of my walls, ceiling and carpets. His advice was not to go for one of these, as they are geared to the US projector spec, not the UK. He said the Grey Wolf would likely result in a "glittery" image using the UK HD20.

Still unsure whether I need someone to come and adjust the thing though! I forgot to ask him this!

I've never heard such a strange explaination for why not to buy a screen....US projectors aren't any different to ours (bar maybe the odd model number change) even UK models can display NTSC at 60Hz so no difference there.

However he did have a point that Greywolf screens tend to produce 'sparklies' especially with brighter projectors (mine used to even with a fairly dim AE1000 (ND2 filter helped against that though). They do a brilliant job of maintaining the image contrast even with light walls however, if you can live with the texture and sparklies. My Beamax is much smoother and no sparklies, but I've love to have the contrast of the Greywolf...it seems you need to spend some serious money to get that kind of contrast boost in a light coloured room so I just improved my room instead....if I ever see a Stewart Greyhawk in a big size secondhand I'll grab one.

That's interesting - the guy who called me was one of their sales representatives, so the "technical" explanation may well have been suspect! I don't think I could live with the sparkly effect, so I think i'm going to accept the fact that my black levels are not going to be stellar and go for a matt white screen. Painting the room a darker colour is not an option!

have you found any decent prices for the panoview screen, currently looking for one myself.

cheers

jagsta · 22-10-2009, 1:51 PM

The best price i've seen online is with Touch AudioVisual at approx £327 + £8.95 delivery, however they obtain stock direct from Optoma who are about to release an updated version of the screen (the housing is being modified in some way apparently), so they estimate 3 weeks before they'd be able to ship it.

I've ended up buying mine with projectorpoint.co.uk, they have it in stock and after a bit of bartering with them they reduced the price (they advertise it at 310 + VAT + Delivery, totalling around £370) and chucked in next day delivery free of charge. It's due to arrive tomorrow.

excellent just been onto projector point and got me a screen on the way

Jagsta,

Back to your original question about setting the limit stops. Yes you can do it yourself and it's not rocket science. I have this screen myself and use it via the 12volt trigger to my Infocus IN82 projector.

When you receive your projector it should have included a 5mm allen key - this is for adjusting the limit stops, of which there are two. These are located on the casing near the lead inputs and are probably covered with a pull out rubber bung. The one on the front of the casing controls the 'raise limit' - you probably wont need to touch this one; and the one on the rear of the casing controls the 'drop limit'. This is the one you need to use. Remove the bung and insert the allen key into the hole until you locate the nut, turn it clockwise to raise how far the screen will drop (ie it wont drop as far), or counterclockwise to allow the screen to drop further. I found with mine, it took around five full turns to make a difference of about 25mm or 1 inch, but experiment gradually.

One tip. Set your limit stops before you connect up the 12 volt trigger. Otherwise you will have to keep switching your projector on and off.

Good luck.

Davy,

thanks a lot for this info, it's exactly the level of detail i've been looking for, I couldn't imagine how it would be particularly difficult, the main issue being knowing which one of the limit adjusters to use!

I'll be giving this a try on Saturday when i've got the Tupplur down and the Panoview installed in its place. The Tupplur lasted a week before I became dissatisfied, I hope the Panoview lasts a little longer!

Davy · 23-10-2009, 2:00 PM

You should be okay with this one. I've had mine for quite a while now and am extremely pleased with it.

Grangey. · 25-10-2009, 6:45 PM

Davy,

Ive just seen your response, whilst the screen I havnt isnt the same as the one listed, it does appear to have the two small holes you mention with "up" and "down" listed.

This will probably sound very silly. But I want to change my maximum drop to further up, but it does drop considerably lower than I wish it to. Would there be a limit do you think on just how much adjustment you can make via the adjustment method you mentioned?

Also, do you adjust the settings with the screen down or up?

Thanks

jagsta · 25-10-2009, 11:53 PM

I installed my screen yesterday and adjusted the drop to match the projector properly.

Davy, I struggled to locate the adjustment unit at first, it was where you said it was I was just expecting it to be on the end of the unit not the underside for some reason!

On my unit, the rearmost adjuster (nearest the wall) adjusted the upper raise limit. Adjusting clockwise lowered the limit, counterclockwise raised it. Not sure if we've got different version of the screen maybe?

Grangey - I moved my lower limit up by around 15cm, I don't think there is a physical limit to the adjustment, I think you could keep on turning the adjuster as many times as you liked. Not sure if there is a limit to how far you can actually make it change though.

I'm very happy with the screen itself, although 1 thing is bugging me - i've got it connected to my HD20 using the supplied 12V trigger cable. This works ok, but when I switch the projector on the screen descends for a second, goes back up again, then finally descends after another 5 seconds or so. I don't know why it's doing this but it's a bit annoying. I assume it's the projector.

Grangey. · 26-10-2009, 8:35 AM

Thanks Jagsta. So do you have to do the adjustments with the screen up or down?

jagsta · 26-10-2009, 10:38 AM

I did it with the screen partially down, so it's between both limits, once you've adjusted the drop a little, press down on the remote or the casing and see where the new limit is, then retract it a little way, and repeat the process.

Davy · 26-10-2009, 7:41 PM

Jagsta, yes sorry, when I re-read my instructions I can see why you thought the adjusters were on the end and not where you found them (which is also where mine are). I only meant it to mean, the lead end of the casing as opposed to the other end; but you got there in the end, so well done. As to the difference in movement of the screen, I guess clockwise/counter-clockwise depends on whether or not you are standing at the front of screen or have moved to the back -

Why your screen, starts to descend then goes back up, before fully descending is a bit odd. Something must be sending a 12 volt signal to the screen and then temporarily loosing the power. As you correctly say, it probably is the projector. Have you tried connecting a multimeter to the lead at the screen end? This would let you check for 12 volt continuity from the projector.

Grangey, I needed to raise my drop limit over 50cm and had no problem with this amount of adjustment. As Jagsta has already mentioned, do it with the screen partially down. However, do your final checks by letting the screen do its full run at your new settings.
