whoa, that sucks rboster. Sorry to hear of your trouble. I hope my "green line" problem isn't on the road to the same thing. Though it's still a rare problem for me.

Best of luck and keep us informed.

Thanks Rich for the kind thoughts...

It was strange (to some degree). About a month ago, one day I stopped getting a signal from either HDMI input. After a long day downloading firmware etc, the picture came back...so new firmware "seemed" to solve the problem.

Fast forward to this week, I watched a movie Tuesday night and no issues at all. Last night I went to fire the projector up to watch the KU game and ....nothing....no indicator lights on in front. A complete DOA. So, I'm not sure if the previous issue was the first indicator of this current DOA? Or, are the two issues unrelated? I had to chuckle, since I pulled my receipt I realize I bought the projector 363 days ago from when it died....so happy anniversary JVC!!

All that being said, it puts out the best picture I've ever experienced in my set up. So even paying a $100 to ship it in for repairs, if I never have another issue, I still be pleased with the purchase.

Ron

PS: Sorry to hear about the issues you are having with your projector. I'll make sure to post the results of the repairs (when needed to be fixed etc). I'll also post my experience with Mendtronix repair facility.

I thought I'd post my question here too, since the X500 and X700 are so similar.

How do you guys adjust the sharpness on your projector?

On every guide I've read, it is suggested that you increase the sharpness to the max setting, then decrease it until the white double edge completely disappears.

There is a setting, one of the MPC sliders, that seems to have something to do with sharpness, but there is no way cranking it up to the max produces any visible artifact (it does something, but the effect remains subtle, even at 100...)

So, is there another setting on the X700 to adjust sharpness?

There is no "sharpness" setting like there used to be on older JVCs. The non-adjustable sharpness setting is great out of the box so there's no need to worry about adjusting sharpness. To increase "sharpness" you have the option to enable MPC (the enhance slider) and/or enable Clear Black.

Personally I have enhance set to 15 for most content, eshift off, and clear black off. This is enough "sharpness" enhancement for me. YMMV and you may want to have other features enabled but know that having them on at a certain point will do more harm than good. Use common sense. Use it in modest amounts.

Thanks for your wisdom. I just like to have the option, even though I might not use it. I like my picture to look digital, if that means anything.

My beloved 700 comes home tomorrow...can't wait to fire it up and catch up on the movies that I have backlogged over the last three weeks.

For those eyeing the B-stocks Mike mentioned.....I have no regrets with this projector and would buy it again in a heartbeat. My only regret is not jumping on the JVC bandwagon earlier (though my Planar served me well).

Yes, the planar is serving a hard 20 for his crimes.

Does anybody know what kind of contrast I can expect from the rs57 with close to shortest throw? (pretty close to max zoom)


I have an rs40 right now, but will be upgrading screen to 145" wide 2:35 screen, and its close to max zoom for my projector throw distance. Just wondering if I will at least double or even triple contrast right now. RS40 is about middle throw with current screen size. thanks

Cine4home cites 980 lumens at max zoom and 31000:1 native contrast. Enabling the dynamic iris will get you to over 350000:1 measured dynamic contrast.

Im assuming this is with the iris fully opened. Or is it closed.

That's with the iris fully open. Fully closed you get 380 lumens at max zoom and 62000: 1 native contrast. But remember one of the biggest advantages this model has over previous generation projectors from JVC is the inclusion of a dynamic iris. It's generally well programmed and I think most people would leave it enabled. With the DI you get the best of both worlds, bright peak whites and dark inky blacks.

But the gamma is generally not stable as a result of the DI?

You wouldn't have a well implemented dynamic iris without dynamic gamma. The gamma changes in conjunction with the iris on purpose. This is to offset brightness compression. If you were to have the dynamic iris enganged without gamma compensation the image would simply get darker. Whites would look dull and the image in general would have a "flatter" appearance especially in dark scenes where the iris closes down the most.

For the JVC I think their implementation is just a tad too aggressive and the iris mechanism is just a little bit too slow and as such sometimes you can see shifts in gamma when we go from a very dark scene to a bright scene quickly. Maybe JVC is working on a DI version 2.0 for next year, or at least I hope so. After comparing it with Runco's DI implementation a lot more recently, I still think Runco's DI is the best I've ever seen. I have a Sony VPL-W30ES coming tomorrow because I want to take a harder look into what Sony does with it's DI. From what I've seen from the 1100ES and 600ES I'm not convinced their implemented as well as many have cited. They're not aggressive implementations which means they rarely clip whites and that is one of it's most provocative features.
