JVC RS40 3D PJ

[Anonymous]

Anyone calibrate one yet? I plan on calibrating a friends this weekend to see if there are any issues.

hi Tyler
it is straight forward.
have fun.
make sure you get the THX software for it.

The 40 is not THX certified … so the software may not work here.

ISF modes maybe …

argh!
Good catch michael, thanks
no isf or thx modes on the 40.

Can you still use the PC software to control display settings, even though there are no ISF or THX modes, or do you need to use the remote?

[Anonymous]

Which software would that be? The only software i know of is the THX one … and the calman will activate the ISF modes if the projector is an ISF one. Which it might be. Nothing too special about things having ISF modes. Calman 4.2 should interface with it … if not … then simply do it in the user menu. User controls and then the grayscale. (The Calman ISF interface with the JVC is considered buggy at the moment so those projectors don’t show up in the list of compatible units when the DDC is activated.)

I was thinking the THX software or possibly CalMAN. Sounds like it’s easier to just use the user menu. I won’t be doing that much in this case, anyway, as in my upcoming calibration most of it will be done with a Lumagen.

Thanks.

I tried to use the THX calibration interface software on a DLA X9 and a DLA HD750. Both times I could not get the PC to communicate via the RS232. I follow the instructions and the cable is good. Anyone else had a similiar expereince?

Hey Paul,

What kind of cable were you using? It has to be a null modem cable … so not the one you would use on a pioneer elite … for instance.

Hi Michael,

I tried both Null and Straight through (one at a time). This there a specific software for those models? Could I have the wrong THX software?

[Anonymous]

Turn on rs232 in the menu of the tv …. may be set to lan …

I’m due to calibrate an X3’s 3D settings tomorrow but it’s just occurred to me that I’ll need a 3D source and I only have a Sencore 403. Am I right in saying that I won’t be able to do it as things stand?

Hi Julian,

You will need to force the x3 into 3d mode somehow to turn the glasses on and get them to sync.

Do you know what sources are connected? If you have a 2d to 3d option in a source that should be ok.

Let me know how you get on with X3, was working on an X7 at the weekend, the offset controls were a bit ugly and corse and introduced visable colour shifts at low ire’s with jusy a single click. I remember on the THX course we ended up with areally blue 10ire.

[Anonymous]

There’s a PS3. Any good?
Yes, absolutely right about the offsets!! I had trouble with blue. 10 ire in particular. Not sure that I absolutely fixed that. The problem was that I had a mid-ire ‘sag’ in blue. I tweaked blue gamma in this zone to improve things. It worked.

[Anonymous]

Pretty sure the PS3 won’t do it, some bd players can from Panasonic & Sony I think, may be worth getting hold of cheap one to add to your arsenal if there is no 3d option on the sencore.

On the low ire’s I found i had to adjust out somewhat by eye, not bad in the end but noticed that anything only just above black was very blue but ok once the levels raise a bit, will work on.

How did you find the native gamma curves, i found the pre sets were pretty shot and only got about 2.1 on the 2.6 setting and had to ramp the lens apature down to about -5 to get something close to a straight line response. In a magnolia room with white ceiling though!

What fL did you end up with? I found the X7 could pump out a lot of light at certain settings but after calibration and stopping down the lens it was pretty poor, I think having to reduce the green gains so much loses a lot so best to minimise ths where possible.

[Anonymous]

Same issues as you describe re gamma. 2.6 to get anywhere near 2.2. 650 hours on bulb aperture opened completely up I got 9.5 fl on normal bulb. This was in good demo room – but with white ceiling. Sounds like parallel issues between our 2 machines.
