Finally had a chance to put my Da-lite Hd progressive 1.1 screen and WOW. This just replaced my aging high contrast cinema vision and the difference is dramatic. The screen texture and shimmering that bothered me is completely gone. Never noticed that my whites wern't really white until viewing the new Hd screen. The image now is so clean with nothing distracting me also being a white screen, my image is brighter with more "pop". This was an upgrade to prepare for my eventual upgrade to a 4k projector but I have to say, this is the best I have ever seen my projector look.

Details in case anyone is interested. 80" wide screen, 10.5 feet to seating position. Black ceiling, floor, with dark color side walls. Fully light controlled. 13.5 feet throw distance for the Sharp xv-z20000 dlp projector. Older projector but definitly aging gracefully.

Ck

I'm no videophile, but I know what looks good to me.

Just to add to the database on this very high end screen material from Da-Lite...

Last night I completed a swap-out of the roller/screen on my 106" Da-Lite tensioned Cosmopolitan Electrol. The original screen material was Cinemavision 1.3. The replacement is HD Progressive 1.1. I have been planning to replace either the fabric of the entire screen for some time now as the original Cinemavision material had developed the dreaded "stickness" syndrome a couple of years ago and I was tired of wiping the thing down with denatured alcohol every 6 months.

As has been universally reported by others here, the difference the HD Progressive fabric made compared to the Cinemavision was immediately noticeable. The projector is a Pioneer Elite FPJ-1 (JVC RS2 clone). The Projector lamp was replace fairly recently, having only around 100 hours on it.

I have always considered the Cinemavision fabric to be a good choice for home theater. However, I now "see" deficiencies that I did not even know were there until they were gone. Uniformity of color and brightness are noticeably improved which lends a very smooth, more film-like look to the image. There was a slight "harshness", for lack of a better description, to the Cinemavision screen that has disappeared with the new fabric. I do not see any decernible loss of brightness with the slight drop in gain, and black level is at least as good, if not better.

I have been thinking recently about replacing the Pioneer projector with a newer JVC, and I know there would be some improvement with a newer model. However, I have to say this new screen has given the workhorse RS2 chassis a new lease on life. I was consistently impressed with the look of both Blu-ray and HD broadcast images staying up way past my bedtime last night. I'm looking forward to revisiting a stack of favorite Blu-rays this evening for some more in-depth assessment of the new screen.

Anyone considering a high quality screen should give the HD Progressive serious consideration. I've looked at a lot of front projection in all types of applications. I have not seen any home theater screen that I could say is better than this.

One note regarding this application. Da-Lite does not normally offer this fabric with the Cosmopolitan screen. The roller/fabric made for me was a custom build. I happen to work for a company that does considerable commercial business with Da-Lite. They did me a favor.

Hey Craig...any thoughts on the new 1.3?

I am looking for a screen to go with the new Sony 500/600....short-listed are the 1.1, the 1.3, and the Carada BW (price puts this screen on the short-list)

Interested in hearing your thoughts on the 1.3

Thanks

I'm also enjoying my 133" JKP 1.1. It's a clear upgrade from my previous 119" High Power (2.4) screen. Here's some quick comparisons between the JKP 1.1 and the High Power 2.4 surface.

Pros:

1. This is by far the main reason for why I switched: My High Power screen had clear and distracting uniformity issues (I had my High Power screen replaced twice - issue persisted), there were both horizontal and vertical banding visible in bright scenes, especially if the camera was panning. The JKP surface has -almost- no visible banding (there are a few very faint vertical faint lines due impressions from the roller when the screen is kept rolled, they mostly disappear after the screen has been rolled down for extended periods).

2. My Sony HW50Es has slight white field uniformity issues, but they are less visible on the JKP 1.1.

3. The image also seems smoother, or even sharper as the surface is much smoother. There is less of a sheen/grainy effect of the surface.

Cons:

1. I do miss the brightness of the High Power screen and I had to turn my lamp from low to high. 3D isn't as bright either.

2. Ambient light rejection is clearly worse. For me this isn't such of a big deal as I really don't enjoy watching movies/series with any ambient light as it just kills the contrast, even if the option would be "nice to have"

3. Even with the lowered gain I think the black bars in widescreen movies have slightly elevated blacks due to ceiling/wall/floor reflection (even if my room is mostly light controlled for the first 2.5 meters from the screen). This can be fixed by improving reflection control wink.gif

In the end, I'm very happy with the switch.

You did get a somewhat larger screen too, over the previous High Power. Glad you are enjoying it.

I haven't had time to really test it compared to my StudioTek 130 screen. It looks somewhat similar though. I'll try and do some testing this week. And I'll try and test the HD Pro 1.1 against the Stewart Cima Neve 1.1 too.

I'm not sure I understand what you mean. Do you mean you swapped the StudioTek 130 to a JKP 1.1 screen?

Hi Craig. I, for one, would love to hear your thoughts when comparing the JKP 1.1 to the Stewart Cima 1.1

Hope you get to that soon!

It's a tough call. I have another set of samples coming, and I'm building a new screen sample holder to better test screen samples. So far they are very close as far as I can tell. Stay tuned for more testing.

did anyone get the jkp 1.3? wondering what full screen impressions are

Love sports, movies, and games. Slowly some day I'll add a projector and screen. Until then, I'll build up my library.
