Official JVC RS40/X3 Owners Thread - Page 45

Hello Everyone,

There is a firmware update for the RS40/X3. This addresses the situation that occurs when changing the Gamma from the remote in the 3D mode. It also addresses 3D Blu-ray player compatibility.

There is a separate firmware update for the RS50/X7 & RS60/X9 that only addresses 3D Blu-ray player compatibility.

You can find the firmware updates here:
http://support.jvc.com/consumer/custrel/index.jsp

You will notice there are two links. One is to a document that explains how to do the update via the USB connection on the projector. The other link is for the actual firmware.

Chris

How do you know if you need the firmware? If 3D is working with your current player, is it necessary to update?

There's a definite incompatibility problem between Nvidia cards and JVC's 3D projectors, that appears to be certain. I don't know, or care, who is to blame, but I hope the companies talk to each other ASAP and work out a solution.

Hi Sam,

Bottom line on any firmware is always: If you're happy, then there is nothing you need to change.

Having said that, I see no downside to the firmware.

Chris

A Unicorn flashing its soul - is that the same thing as baring its soul?

Nice find

Chris, is there any way you can find out more details on what the compatability fix is for? I am having a problem with the NVIDIA graphics card syncing to the JVC, it works fine on all of my other displays.

I asked Gary to forward my issues to Japan support today.

Thanks.

I have just about convinced the wife to spend some more and get the RS40, but I need to answer some of her questions. This question come from the past few weeks of me telling her about some of the possible (maybe not true) faults of the 3D part.

I have a new 133" HP screen and it sits 16" from the projector. Our chairs sit about 17" to 18' from the screen. Is this to far away for the full effect of the 3D? When the 3D part is used the room will be totally black.

I believe it is just for Panasonic 3d blu-ray players.

For 2.35/40 material which I have to throw a ~128" 1.78 image to do on my 2.35 screen, I already am at high lamp, and fully open iris.........I could get used to it a bit dimmer, but I would not want to..........I need to order a highpower!

This is only for the Panasonic BR and Gamma switching improvements. The NVIDIA issue has been reported and it will take a few days to see what they can do.

Gary, thank you. At least it saved me the time of doing the firmware update.

I can provided the EDID information of the JVC when connected to the Nvidia card, I ran a second monitor to extract the EDID information. It says native connection should be 1920x1080 but as Petri and I have discovered, the JVC is multiplying the horizontal resolution by 1.5 times. So it becomes 2880x1080 or VGA res 640x480 becomes 1280x480, etc.

If you hear anything back, please let me know. I'll test any updates from JVC support and provide feedback.

Engineer's typo? Too much caffeine that night?

I am getting really excited reading all the rave reviews about this projector. I have had it with my Epson and received my brand new replacement today (8700UB), I hope I can move it cheap and fast and find a RS40 soon!

ok ok, 640 x 1.5 = 960 I get it...

IT'S STILL BROKEN!! boo...

I might try picking up a GT240 for kicks tomorrow just to give it a shot. Petri is going to try the ATI card with the latest drivers which just came out. Crossing my fingers 1 of the 2 works. I just don't want to start with a dedicated BD player if I can avoid it.

Thanks Gary. Why is 1080i Top and Bottom not supported?

The ESPN3D channel is broadcasting the first NBA basketball game tonight in 3D. It is being broadcast in Top and Bottom format.

My initial thought was that the lack of support for 1080i top and bottom format would be a showstopper for me if it meant no ESPN3D. However I then remembered that ESPN3D broadcasts in 720p. So from the spec I see this would be supported.

My concern, however, is that one day they may change to 1080i. Or that another channel that's 1080i currently may broadcast future shows in Top and Bottom format, and we wouldn't be able to watch them.

Do you know why TnB is not supported at 1080i? If you tell me that due to the technical nature of 1080i there will never be a case for a broadcaster to use TnB format on 1080i, then that's one thing. But if the possibility exists, I see this as a possible future compatibility issue.

If you can please elaborate on this that would be great.

Speaking of Top and Bottom 3D - is anyone watching the ESPN3D NBA game in 3D on their RS40/50? This would be a great way to confirm that TnB is at least working at 720p.

For nearly 3 years I have been using a RS2/HD100 and a Lumagen RadianceXD with correct colorspace dialed in. I have been very satisfied and still am. I have not been experienced the decline in brightness and build up of dirt that as been reported by HD750/RS20 users, of course the lamp reduces in brightness, but changing it I go back to what it was when new and I havent detected any dirt in the lamp house.

Can anyone tell me what I can expect in increased 2D performance? I have zero interest in 3D for the time being.

Seriously, I didn't even notice your typo. I was (only half kiddingly) suggesting that an engineer made a typo that resulted in the JVC/nVidia incompatibility. I wouldn't be at all surprised if a simple coding mistake is responsible for the gamma switching problem on the RS40 that necessitated the JVC firmware update. Maybe a mistake in a subroutine meant that cycling through the gamma presets causes the projector to drop accidentally into an emergency shutdown mode. Cut to the engineer making a five stroke change to the code, and starting the upgrade instructions for JVC customers worldwide. (Maybe that's a thought only someone who has written computer code could appreciate. Never mind.)

Anyway, maybe Chris can let the engineers know, so that they can fix the problem quickly. Hopefully, it's something simple. (Cut to an engineer screaming, "Do you know how many lines of code I'm gonna have to change to fix that??? How many people could possibly be affected, anyway? (OK, I should stop doing that.)

Thanks Mark and Henrich. I honestly did not see your reply Mark, that thread flies by I will be mounting it on a shelf on my back wall dead center of the screen from a throw of about 15-16ft

Are you sure? The 460s, 450s, and the 430s I checked out stated they had 1.4a hdmi ports. Here's Nividia's official statement on the 450 GTS:

HDMI 1.4a Support
Support for HDMI 1.4a including GPU accelerated Blu-ray 3D support (Blu-ray 3D playback requires the purchase of a compatible software player from CyberLink, ArcSoft, Corel, or Sonic), x.v.Color, HDMI Deep Color, and 7.1 digital surround sound will be added in a Release 260 driver. Upgrade your GPU to full 3D capability with NVIDIA 3DTV Play software, enabling 3D gaming, picture viewing and 3D web video streaming. See www.nvidia.com/3dtv for more details.

I too am currently using the RS2. My RS-50 is apparently being shipped out on Monday so within a week I'll be able to give full on impressions comparing the RS2 to these new PJs. I realize the RS50 isn't the 40 but the tech behind them is the same so I'd like to think the difference/improvements over the RS2 would pretty be the same with the RS40.

Based on what I have read here and elsewhere, it seems the improvements for 2d over the RS2 are:

-sharper
-better/smoother motion
-brighter
-more image depth
-better contrast ratio/black level
-superior/more accurate colour reproduction though for your colour corrected RS2 this (I'm guessing) doesn't factor in

I am expecting/hoping to see a clearly superior improvement compared to the RS2. I went from the RS1 to the RS2 and the improvement there was easily visible to me and worth the upgrade so I'm pretty sure it'll be even more obvious and greater with the RS-50.

I don't know what you guys use to manage, peruse, and basically categorize/track your movie files, but you should check out an app I wrote to do that for my HD based ISOs and other movie files. It download info from blu-ray.com (more detailed BD info than IMDB) or from IMDB. With this I know what HD to swap in; the aspect ratio to setup for and using the "favs" feature, keep track of the movies the family is interested in watching as we go through the list.

Here's a screen:


There's another screen view for use in just movie browsing - and other numerous features. Best part is that it's free. Check my sig link for more details and to download.

After all this Sony love I decided to give the 570 a try for that price ($138 on Amazon w/ free ship!), and decide whether I need to keep the Oppo, (I love my Sony 400 disc BD changer!). Now that I bought that Monoprice 4x2 matrix switcher waiting for the Denon 5308ci 3D upgrade, I may not need a dual output player. Of course the biggest factor in keeping the Oppo will PQ. It'll be interesting to see what Sam and I feel is best.
