Official JVC RS-50 Owner's Thread

Both?

You have both and that's all you have to add in 5 hours since your post? Pictures please as I'm told they haven't landed in north America as of yet.

He is an AVAD dealer...

shipped from ?? Are there dealers in CA with these in stock?

looks great, enjoy!

adidadi,

Can you post the dimensions of the box and weight for the rs40? Just trying to determine shipping costs. Thanks.

OK- you've got an rs40 and an rs50. How about a comparison! There are lot of us debating the two units and if the extra cost is worth it.
Thanks,
Frank

So you decided on both
It would be nice to hear the compare if you plan on opening jr.

So, I was looking at a comparison, between the RS40 and 50 on projector central, and they appear to have the same brightness, is the only difference the greater contrast?

Can you please view the single pixel grid pattern found on the AVS HD 709 calibration disc and let us know what the convergence looks like, and for any errors, how much it is off and whether any convergence issues are uniform across the screen?

Have you had the RS20 or RS25? If so how would you compare the sharpness of the RS50 to those?

Of course rs50 has
CMS

THX cert and ISF - depending on how much value you put in those.
For me it sounds like it comes down to how much better are the blacks and how accurate are the colors on rs40 which features a rec709 setting for color management.

Once you've downloaded & burned the AVS disc image, please put up the disc's main menu and look at it from a very close distance. Do you see any digital noise, like a very fine layer of film grain, in the image? Or does the menu look like it's been carved of a solid block of granite?

I am looking for that information too, would be great if you could let us know! Thanks

Could you tell me if the mounting holes are in the middle of the underside of the pj or off to one side?

The internal grid pattern is no good because it is a two pixel wide pattern. This masks convergence. A single pixel grid with single pixels inside the grid boxes, like is provided on the AVS HD 709 disc, is excellent to check convergence.

You can download and burn the disc for free - it is provided here in the forums: http://www.avsforum.com/avs-vb/showthread.php?t=948496

Put up the single grid pattern (its under the misc. patterns section). Look at it from your normal seating position. It should have NO visible color tinges. Then walk up to the screen and check. You'll see some misconvergence. A tiny bit is fine. Is it uniform? How much is it off (1/4 pixel, 1/2 pixel etc). Now look at single pixels displayed in the boxes. Does it look like a single pixel, or does it look like a grouping of a red, green and blue pixel? The wider the grouping, the worse the convergence. Please let us know what you find.

Its a great disc to have no just for convergence but it has other very useful tests as well, such as testing interlacing , motion handling and more, not to mention great patterns for setting the basics.

There is also a radial pattern that is exceptional for testing sharpness and detail resolution. Its under the misc. patterns. Pull it up and look at it from a distance. How far into the middle of the pattern can you see before it gets blurry? Is there any color fringing or "tint" to the image? It should be black and white only. This is one of the most revealing torture tests I've seen yet for projectors. For example, this pattern on the RS1 shows a lot of red and red. In the RS20 it shows it too, but less so. And on the RS50...?

From what I understand from the manual the mounting holes are where the feet are, you have to take them off for mounting.

If the AVS disc isn't handy, any SONY pictures blu-ray (e.g. Casino Royale) should have the requisite patterns (including a single pixel thickness white grid, among others).

You access it usung code 7669 (which, of course, spells out SONY).

I am wondering, so how many of these are actually in the wild?
Am I missing something or is the only differences between the RS40 and RS50 the contrast ratio?

Fundamentally in terms of optics, the differences between RS40, 50 and 60 are contrast.

However, the 50 and 60 additionally have an RS232 port, LAN port, VGA port. They also have full CMS capability and other additional picture adjustments that are not found on the RS40.

Also the 50/60 have an "advanced" dual aperture/iris system. It isn't mentioned with the 40 so I am assuming that this isn't a typo. The dual iris has one infront of the lens and one infront of the lamp itself. With each press of the aperture control, it alternates between the two. It is not clear why this is better, but we have theorised that ANSI contrast may be better maintained by adjusting an iris on the lamp. This is not proven though.

Amazingly these extra ports mean the 50/60 weigh almost half a kilo more!

Note that the RS-40 DOES have the RS232. Otherwise everything you say is correct including the dual iris on the 50 and 60. RS-40 has a single iris in the lens only.

So the Oppo 93 will do a vert stretch on 3d content? That's cool, I was under the impression that we just had to deal with black bars on anamorphic 3d movies. So, how does the 3d look?

-Sean

How exactly are you stretching this to 2.35? I also have the 93 and just curious how you are doing this? I have not read about all the zoom modes on the 93 yet so I assume you are using one of those?

Thanks
