Normally you have the emitter pointing at the screen and the IR is bounced back into the room to anyone facing the screen...

What kind of size room are you thinking of?

Like an eejit I hadn't realised that "Bouncing it" off the screen was viable, I thought that the signal needed to be line of sight. Thanks!

Basically, on ****** Windows 7, I've set my IP, Subnet and Default Gateway to the details JVC recommends, leaving DNS blank. Hooked up via LAN cable with nothing else but power connected and ran the firmware update. It isn't bricked, a complete unplug and replug brings it back but the firmware update isn't applied. Any ideas?

What IP is the PJ set to? I would have thought it would have been 10000% easier to set your laptop and PJ to DHCP and connect them to a router/switch and then they will be able to communicate no problem as long as the firewall on the laptop doesn't get in the way. If thats not possible have a look at the IP details of the PJ and also let me know the IP and all the other network settings you have for the laptop.

Yeah, weird that. I changed the IP details of the laptop network adapter via these instructions.

IP: 192.168.0.1
Subnet mask: 255.255.255.0
Default Gateway: 192.168.0.254

DNS settings left blank

On the projector:

DHCP off, IP to 192.168.0.2 with the same subnet and gateway details as above. I've tried several times with 2 different cables too

[Member 12362]

Have you tried to ping the router and JVC to check connection, sometimes easier to just use a 4 port switch to directly join the projector and laptop

at the command prompt

ping 192.168.0.254

ping 192.168.0.2

[bravogolf]

Hmm, I'm not using a router. Am connecting direct from PC to JVC without anything in between. Embarrassingly I didn't ping the JVC but I suspect it will ping back as the firmware update confirms connection, applies main firmware but fails on sub firmware.

[Member 12362]

Only taking a guess but menus don't always tell the truth, start at the basics and check two way connection with a ping. If okay try powering off the JVC (allow fan to finish cooling in standby first) then power on and try process again.
Good Luck

[breadvan]

I had same issue when the fw update utility reported finding the PJ OK but fw update failed, I think I manually turned off firewall and antivirus and it worked in my last try before turning off my notebook and call it a day.

[Geof G]

Make sure you have no active HDMI inputs...either disconnect the HDMI cables or make sure the devices at the other end of the cable(s) are turned off.

[bravogolf]

Thanks guys. I'll try this again tonight but still unsure what to do differently if the PJ is pinged (I suspect it is but subsequently loses the connection). I don't have any other inputs into the projector, on the laptop there's no firwewall on or AV software running. From reading previous threads it sounds like the issue is at laptop side but I can't see what to do differently! I'm bringing a new ethernet cable home just in case!

[Member 12362]

I had a look in the manual and it shows connection via a router, but does not stipulate that a crossovercable is needed without one. So to guarantee the physical connection cabling I would advise a switch or router between the PJ & laptop. Then ping to check send/receive. Then if all okay, proceed to update.
P.87 briefly shows the three way handshake protocol.

[mikim]

Try using a crossover cable too if you're connecting directly.
Set your laptop onto the ip you require then run angryIP scan over the entire range 1-254 (192.168.0.1/24)
If the pj is on this IP it will show up.

[GaryB]

At JVC we connect direct and with a straight cable. The half dozen PCs we've used have all worked fine with one exception. The issue there was Zone Alarm blocking the packets, even when it was set to disabled. You have to actually stop the Service to get it working.

I have heard of high-end laptops with multiple network interfaces giving problems,as the update software can grab the wrong interface, but we haven't seen it ourselves.

[bravogolf]

Awesome, firmware update worked this evening. The only thing I did differently was:

• Change the IP address on the PC to something else (I can't imagine that had any effect as it was already different from the PJ and consistent with gateway, as in 192.164.0.xxx)
• Used a different network cable (standard CAT5 LAN cable, not crossover)

I had tried two different cables before, one crossover and one not, but it must have been the cable. Anyway, all up and running. Will check does it now retain lens memory settings without having to readjust focus each time I switch and will enjoy Coraline on blu-ray regardless

With apologies to The Fast Show

"You see Bravogolf myfriend, electronics are a lot like women, similar action different day it worked, try it tomorrow and it might not, same model next week a whole new challenge.

any of you JVC X series owner use it with a Da-Lite Cinema Vision 1.3 gain screen (white)????

I use the Stewart Firehawk G3 which is, supposedly, similar to the Da-Lite if I can help with anything?

[Webmonkey]

Well, on AVS there is a thread about screens for 3D projection. The Cinema Vision is supposed to be top notch when it comes to retaining polarization. I am just curious about hot spotting and grain on this screen, as it was bought back in 2004 for a Barco CRT which is super dim compared to a modern digital. I am also curious if a 1.3 gain screen would destroy the black level advantage of the JVCs.....

I used to run a HD350 with a 1.5 gain screen and with the iris set correctly (to give 12fL off screen) the black level was great. Remember with the JVCs you can always throttle back the brightness if you have some screen gain, but don't fall into the trap of closing the iris right down just to get better blacks, there's more to a good picture than having a lower absolute black level. The JVCs totally killed my previous AE3000 in dark scenes as there was no dynamic iris to crush down highlights in darker scenes.

Hi im coming from a jvc hd 350 and know looking into buying a X70. Im not intrested in the 3D side of it just the 2D. The question i have is the upgrade a noticeable upgrade or a night and day difference upgrade ?

Thank you.

[kbfern]

The X70 is a considerable step up from the HD350, it is much sharper handles motion better much higher contrast ratio is brighter has a cms and has e-shift so yes it should be a night and day difference.

Thanks for that, you ended up upgrading from a hd 350 ?

[kbfern]

I wish I had I have never owned a JVC though plan to get one later this year.

I have seen many JVC's over the last 2-3 years and for reasonably long periods of 1-4hr sittings.I have seen HD350/750/X30/70 models and can say that the difference between the HD350/X30 is substantial let alone the X70.

The HD750/X30 was surprisingly large if you look at iraz thread you will see our views on the difference.

JVC750 or X30?

The X70 takes things up a further notch with better optics/contrast ratio and e-shift takes it up a further gear.

I will say though that it is very likely that JVC will be bringing out a new model between the X30/70 in their next lineup to be announced in about a month (models available Dec).It should be called the X55 and this will have e-shift included and is expected to cost around £4k.

I would be tempted to go for that and save £2k on what X70's go for unless X70's become available nearer Dec for much less than current asking price.

[bravogolf]

Forgot to update the thread, for the benefit of anyone who else who happens upon here with a similar issue. The firmware update fixed the issue for me (whereby after loading lens memory the image would be out of focus everytime even though I'd stored it in focus) so all's well!

[bravogolf]

Apologies if this has been done already, what are the recommended 3D settings? I stuck on Hugo last night and 3D was just OK. I'd read that this was an average performer in the 3D domain but I wonder when I watch it is it something I'm doing/not doing that could cause such iffy 3D!

Also - what do you recommend for 3d glasses? Need another pair.

Can you elaborate on "just ok" and "iffy", please?

Are we talking brightness, cross-talk, depth, or what?

[mooro1973]

Anybody looking for cheaper 3d glasses might want to try these:

http://www.amazon.co.uk/gp/product/B...ls_o00_s00_i00

I just got a pair as an experiment and works perfectly with the x3, as bright as the officials and flicker free. Also have the added benefits of being reversible, at the touch of a button between left and right lenses, and so compatible with other active shutter screens too. They are also rechargeable, and "only" £26 delivered.

It doesn't show compatibility with the x3 but if it works it works i guess!
So this would work on my x30? And maybe my Samsung ps51d8000?

[mooro1973]

I think if a system has infrared dlp shutter technology they work. The incompatibility between brands is down to the left and right lenses not always being in synch. With these glasses the synch is reversed at the touch of a button. Only got the glasses today, switched between the jvc's and these and couldn't see a difference.

Might be worth a punt
But think my plasma has bluetooth glasses so not compatable

It was bad enough that I often took the glasses off to compare and confirm that 3D really was working! I'm fairly sure it's working, some of the blurriness goes when I put the glasses on but it's riddled with cross talk and lack of clarity. I have the transmitter plugged in, pointing towards the screen and my glasses have a new battery in them.
