hello all
i am about to create a cinema room. the projector is a jvc hd350.
i dont really want the room to be all dark walls and ceilings. black velvet is deffo out.
would this screen be the ideal choice. it certainly looks like it.
or am i wrong?

Expensive but very good, 0.8 gain. you will need to think through FtL and image size

davie · 24-02-2009, 7:54 AM

i see they do one with a gain of 2.
i am confused as to why people spend so much time and money darkening rooms when these products are around ,if they work.
i have read that viewing angles are not as good. in the majority of the pictures of home cinemas i have seen, the screen is almost as wide as the room, with the seating pointing straight at it.

I'm looking at these screens also, just waiting to hear back on how much a 100" Supernova Flex will be, awesome looking screen that looks like it will be ideal for viewing in a living room enviroment where black velvet won't be allowed, well no too much anyway

These screens help and improve things but they are very expensive in comparison. Plus they will never compete with a fully light controlled room

Hi Guys,

Genesis Technologies are UK distributor for the Supernova CI (custom install) range of products.

There is no doubt that the drop down and masking screen (Flex and Epic) are expensive but they are also universally hailed as the best screens on the market for picture quality and engineering/build quality. The first time you see a Flex you understand where your money goes.

They do also have a range of less expensive fixed frame models as well which offer the benefits of the Supernova fabric at a more moderate price point.

Remember, there are no other screens in the world that work like Supernova rejecting off axis light but still having a low gain and very wide (close to 180 degrees) viewing angle.

If people would like to know more then please let me know where you are so I can put you in touch with a suitable dealer.

One well known company that believes in Supernova is Stone Audio who have an Epic in their cinema demo room (which has pretty much the same stuff as we showed in our last high end event demo).

Cheers

ok heres two situations

a normal room with blackout blinds and light coloured flat matt non reflective paint with the supernova screen, and all the lights out.

a room with black velvet all round a regular screen and on the ceiling in front of screen,with the rest of the room having very dark paint on floor and ceiling, and all the lights out

is the second one still going to blow the supernova out the water?

warbie · 24-02-2009, 4:35 PM

Yes, I suspect there will be little contest.

I don't doubt the Supernova is great at what it does, but there will be trade-offs.

//edit - I haven't seen the Supernova in the flesh btw - this is based on comparing various grey and white screens. If you have the lumens to handle the negative gain and haven't the option to cave your room, the Supernova looks like a great option. Have you considered a Firehawk G3 screen btw? Grey screen with positive gain - my room has been darkened and i'm toying with getting one of these just to help get a little closer to those elusive crt blacks

I would be shocked if the velvet solution is not better.

Why ? Well the MEASURED difference (ANSI) in my room on a 1.4 gain Carada screen was over 6 times moving from mid blue matt painted walls with dark wall behind the projection screen to velvet walls, ceiling and floor coverings coming back 14 feet into the room (20 foot in all)

Viewing differences looked more than this !

I bet the screen does an excellent job but it would need to perform a miracle to compensate for 20m of velvet !

Maybe light control with some dark fabrics close would compare, but not light walls alone

IWC Dopplel · 24-02-2009, 5:53 PM

Yikes the 120" is £3000 for the cheapest fixed screen. £5,500 for their 'posh' fixed and monstrous prices for anything that moves. They need to be very, very good to justify IMO

Oh and no uprade for me as over 120" they are bespoke and I could buy a LOT of kit for £23,400

Do they really want to deal with the home theater customer

davie · 24-02-2009, 7:08 PM

they are rather pricey.
its a one off purchase though, and how much is being able to use a room for more than one purpose worth.

Neil Davidson · 24-02-2009, 7:09 PM

Guys,

Some interesting comments but also it is clear that (and freely admitted) that much of the comment is being made without having actually seeing the screens working.

I would not suggest that the screen will do a better job of improving ANSI contrast than wrapping your room in black velvet but I am betting that in most cases they will have a rather higher WAF!

The Supernova fabric is an optical surface not a simple reflective surface like typical white or grey screens. The fabric actively attenuates off axis light falling on the screen without compromising the viewing angle. In addition the surface offers superb sharpness and has absolutely no visible texture. At ISE we had grey and white fabric samples from other high end screen companies which we used in our demonstration to show how effective the Supernova is at rejecting off axis light and improving contrast.

There is an argument for using a high gain screen to compensate for the lower light output from smaller projectors after they have been colour calibrated. However this inevitably leads to a narrower viewing cone and clearly an increased risk of hotspotting and shimmer. We only use the high gain Supernova fabric in situations where we need to overcome very bright ambient light (daylight).

The costs quoted by IWC are a little high (more than 10%) and the discussion of the Epic is not really relevant as not too many people use such a screen with anything less than a 3 chip DLP. For what it is worth the Epic certainly does justify it's price tag when compared with any other high end screen on the market. They are delivered in one piece and weigh 250kg. One of my engineers is always on site to disassemble and reassemble and calibrate the unit for perfect performance. The price also includes delivery...

One last comment. At the last Genesis Technologies Cinema Widescreen Event we used a Supernova ONE and HD750. In the white walled demo room at JVC the black bars at the side of the screen (2.35:1 screen when showing 1.78:1 content) remained darker than the projected area even with the Iris closed to position 14.

The projector could of course have the Iris closed down more but the loss of light would not have been acceptable. In this instance no useable contrast was lost even in a white room.

You can see this screen in most of the videos I am in over at AVForums.tv including the anamorphic projection tutorial that was recently posted.

I have not compared back to back but did see the Supernova at Bristol using a JVC 350 and 750. The blacks were very good (in a black cloth box) difficult to see how it would perform with more ambient light. In this situation the blacks were not noticeably better than I see at home with my BW screen and dark velvets. I guess the Supernova is all about ambient light.

I picked the price list off the web, sorry If it was a bit over. At £3k they could be interesting at £20k+ for me they are anything but interesting
