Official JVC DLA-RS46 / DLA-X35 owners thread - Page 32

post #931 of 2080
since the color space is decent overall, the most obvious calibration is with grayscale and gamma. The RS46 needs help here like any other projector using out of the box settings.

I like to bring the gamma down a bit around 10-30 IRE to avoid crushing shadow detail. The RS55 has a specific control to do this without changing the gamma curve.

A good gamma tune stands out on the JVC in a light controlled room with dark surroundings.
post #932 of 2080
is that something that can be done by 'eye'? I've set the gamma on mine to 2.3 under the custom setting, but if I could improve on that I think it'd be something i'd appreciate.

haven't really gotten into the advanced settings on this thing yet.
post #933 of 2080
negative, you need a meter + software to get it right. The default JVC gamma curves can use some tweaking.

I originally bought the MIni3D for my old HD350 which did need some help in getting the colour gamut calibrated correctly. However since Lumagen added the 125 point CMS (and autocal feature) free of charge, it seemed rude not to use it. smile.gif

I agree that the colours on the standard X35 in the right mode are pretty good, but that's not to say they are perfect, just that many people would be perfectly happy with them. The old HD350(RS10) models were more obviously challenged regarding colour accuracy so the addition of the MIni3D was more obvious. However I wouldn't sell the MIni3D now I have the X35 since it still improves the picture in various ways (including better vertical stretch scaling for lens use).

There are B-stock RS46's? Last time I talked to Mike (a few months ago) there weren't any.

I am just finishing up my HT upgrade project. Now the front wall and ceilings are painted a dark gray. I have a new 115" 2.35:1AR screen from Elite that is acoustically transparent. The center is moved up behind the screen now. My RS46 is back from having the HDMI input board repaired and firmware upgraded.

Question for the forum:

Does anyone know if there is an IR based discreet code for recalling a lens memory preset?

I am looking to put the code in a macro for movie mode vs. TV mode for the lens setting.

Thanks!

Iris Setting Question:

What is the Pro's/Con's of Full Open vs. Closed?

I am 2 months into our first projector; X35, with a 108" 1.0 Gain Screen in a totally dark room, with a Black Screen Wall, Ceiling and Med/Dark Neutral Gray Walls. The projector is ceiling mounted about 14' back and we sit about 10.5' back.

Thanks!

Iris open, brighter image, but that means black level is also raised. Close down the iris, black levels improve, but image brightness decreases.

In addition to better contrast, having the iris closed also means you have something to adjust to increase brightness as the lamp ages/dims. This can potentially prolong the useful life of your lamp.
post #941 of 2080
I got my ceiling painted black, and repainted my walls darker (and flatter) and while i'm not completely done, early viewings have me thinking i'll likely close the iris up again. i'm still not sure I see a difference in 'contrast', but with the darker room the black level is more noticeable, and i'm more interested in having great blacks than an eye-scorching bright picture.

Need some help with 3D...

i am new to all the HT stuff so i am trying to learn ....

So jvc x35 hooked up....

3d movie from laptop(file) i have medal brower3

through a none 3d reciver

i get two pictures on the screen....i change to SBS but it stays the same....

do i need a 3D reciver?

thanks for all the help...

Yes, or bypass the receiver and connect the laptop directly to the projector, and then use an audio connection for laptop ---> receiver.

How would I find someone to pro calibrate my RS46 in the Raleigh, NC area?

What type of 3D is the laptop sending? Is it side-by-side where you see two completely separated images split down the middle? If it is, changing the projector to side by side is correct, but you must obey the limited refresh rates that it works at. Are you outputting 1080p at 50,60 or 24 Hz.....or 720p at 50,60 Hz ?

If it is sending frame-packed 3D where you see two images actually on-top of each other then you will need to connect the laptop directly to the projector and not via the receiver.

EDIT:Found number
am thinking about rs46, or the new ones coming this November/December...Currently own an rs40.... Is the 3D better on the rs46 compared to the rs40.

If you're thinking about upgrading solely based on 3D you're going to be very disappointed because its only marginally better. 2D is also VERY similar on these two models. There won't be anything noticeably better. Contrast performance is basically the same and so is greyscale performance after calibration. The only worthwhile upgrades that I would recommend someone to upgrade from the RS40 are the lens memory function and it's a little brighter which makes it handle slightly larger screens.

The 3D is better in the regard that JVC substantially reduced the dark on light ghosting which was the primary complaint on the 1st two generation models.

At this point though, it might be worth waiting to see what comes out in a few months.

i switch to sbs on the jvc
1080p 60 is what comes up...

nothing changes

If it is 1080p60 and SBS, then you are fine going via the receiver. I am confused when you choose Side-by-Side on the JVC that it does not engage. Have you ensured the 3D transmitter is properly connected to the projector?

So, this past weekend I closed down the iris.

I put in the WOW Calibration Disc and had to make some minor adjustments to Brightness and Contrast.

We then watched "SAFE". It may just have been the material, however the movie seemed much flater than usual, it this the result of the iris being closed down?

I will do more comparison testing this week.

What is the difference in closing down the iris, versus, increasing/decreasing the brightness control?

Still learning about the adjustment of the X35 our first projector.

Brightness control adjusts the black level. You want this set so that you can see the details in an image. The lens control is an aperture that opens or closes to let more light hit the screen.

So, I guess I am dialed in since I adjust the Brightness and Contrast with the cal disc after closing down the aperture.

Even with the adjustments (brightness and contrast) correct, with the aperture closed down, less light will hit the screen and the picture will seem darker??

I am still trying to wrap my hands around the relationship of the two?

they didn't really like this analogy when I asked about it, but I still think of the iris as the backlight/cell light adjustment you'd make on a flat screen. I guess the main difference is that doing this on a projector comes with other benefits, doing that on a flat screen just makes the image comfortable to view.

when I was playing around with the iris at first I didn't like it closed either. it did make blacks darker, but it made the image as a whole much darker and I found it APPEARED to have less range. i'm going to revisit this once I get my projector back up and running with the new darker paint in the room. i'm hoping because of the darker room, I can get away with a closed up iris and still have a picture with some 'pop' to it.

It seems that we did lose some "POP".

When I adjusted brightness and contrast after closing down the iris to -15, I may have left the setting a little low. I will try to boost them ever so slightly and see if that brings some "Pop" back.

Frustrating and Fun at the same time..............................nah!

If your laptop has an audio optical out port, that would be good, except you won't get TrueHD or DTSMA.

If it only has a headphone jack, it will work, but I would just upgrade the receiver at this point.

Have you tried a direct connection to the JVC yet?

You do not need a 3D receiver to play side by side 3D content. The whole point of SBS is that it behaves just like a normal 2D picture. There is no special processing or content about it. The only reason the JVC wouldn't engage in side by side mode is if it didn't feel it was getting a compatible resolution and framerate.

According to the X35/55/75/95 manual then it should work at
1080p 24/50/60
720p 50/60
1080i 50/60

You said you are sending 1080p/60 so unless its that "rounding" issue where actually it is expecting 59.94 but because you are sending it from a laptop its 60 (a bit like 23.97 and 24fps issue), I can't figure out why the JVC isn't happy with what it is getting. But fundamentally if you are enabling side by side and the JVC is refusing to change into 3D modes, its not your receiver, its the projector refusing it.

Try sending 720p/60 as an experiment to see if it changes anything.
