JVC X7900 / X9900 Owners Thread

Recommended Posts

Hey guys,

 

Dont see much JVC threads around here, not much projector activity at all?

 

Would like to hear from new 7 or 9 series JVC owners, let me know your thoughts, what have you upgraded from, more importantly how good is the sample you received??

 

Me, I just got my 9900 a couple days ago, it was meant to be replacing my 9500, and lets just say I am extremely happy I had not offloaded my 9500 as yet, I was able to stack them and do a shootout as long as I wished, they are still there now, I run both at the same time, cover the IR port on one machine, hit HIDE on the remote, then uncover the IR port, from then, every time I hit hide on the one remote (which controls both machines) they instantly switch within mere milliseconds.

 

Anyway, aside from Eshift 5 offering almost nothing, clear black Low/Off is certainly a higher quality difference than the difference between eshift 4 and 5, it seems I pretty much have a bad 9900 sample in regards to its lens and panel alignment.

 

I am going through the process right now to try and have my unit swapped as essentially unaccaptable and see how I go with sample #2. If I still dont like that, I am going to wash my hands of the 9900 this round and keep my apparantly stellar sample of my 9500.

 

Here are my lens comparisons. Keep in mind my DSLR lens is close to the screen here, so the focal plane is small, pay attention only to the center line portion of the images as they are in focus on my camera, so the vertical lines and the middle area should be ok to look at.

Convergence, X9900 right side only - left side is stellar:

What happens when I correct the convergence with zone alignment... This is a single 1080p pixel horizontal line pattern, gee this artefact looks SUPER familiar :)

X9500 with normal panel alignment:

Obviously the 9900 can show that screen as clear grey too, but if I want panel alignment to be correct, I get artefacts, yay!

Great to see your feed back and comparisons Javs. Invaluable really fir those considering to jump in ...

 

also so great to see the owners thread. I’m unlikely at this rate to jump off my jvc horse to hop on another till likely next series but look forward to others picking up one of these posting their thoughts and impressions :)

So this below post, from another forum is actually my first thoughts, before I did any of the calibration and comparisons above... Still interesting, the eshift stuff is closesly looked at here...

 

----

I am disappointed overall, and its mainly a gut feeling though, a few things stand out, but it seems to gain a couple steps in one area we give up one or two steps in another area.. I am torn on weather I will keep this projector.

There, got that out of the way.

Here is what my shelf looks like right now...

Eshift buzz is definitely reduced since when I first turned it on, it sounded dead set like an electric razor at first, by the end of the night, 4 hours later it was about the same volume as my old unit, unless you put your ear right up to the 9900 and then the frequency was a bit different. No big deal here.

The 5 seconds improve sync time in Low Lag mode is very nice. 11.8s in low lag mode ON, 16.8s Low Lag mode off for a 4k Desktop to appear.

Turns out this lens is not as sharp as my 9500, once I studied all the corners of the lens it was clear it wasn't quite as sharp. My 9500 lens is pretty much pin sharp in all the corners, this 9900 lens appeared to be, but when I had both projectors stacked, they were both super sharp in the center, but the 9900 slightly less so, and was a couple clicks less sharp on the corners and this could not exactly be brought in line with the sharpness of the center. Both of these lenses though are still far out sharper than my X7000 lens ever was, so I would still say both these lenses are excellent and would quality for hand selection for the 9XXX series projectors, its just that my old one is better than the other.

However because the left side has perfect convergence, the pixel delineation appears to be stronger, however the focus grid is sharper on the X9500 in person, no doubt about it..

The chromatic aberration on the right side of the lens I have come to decide is unacceptable. I think this will be the basis of at least exchanging this unit to try another sample. While the 2/3rds of the left hand side are perfect, I would actually prefer if the panel alignment was out, that it be out by a consistent amount across the whole screen, my last two JVC's were both exactly 1 pixel blur out vertically, which is easy fix, this would require zone alignment and I am not doing that with an MSRP $10k projector.

EShift 5 with text is better than EShift 4, but in real data in video, I am not sure it can be seen at all.

My X9900 is DIMMER than my X9500 is right now at 700 hours. I'll let that sink in for a moment.

I have to run the X9900 on iris -9 and contrast -2 to brightness match the X9500 currently at iris -10 contrast -1. This is a shame, because my X9500 was at least 10% brighter than this when it was new and has dimmed itself since new. So the 9900 starting out where it is, its not looking good here.

There is some ugly super warm colour temp cast over just the menu screen, the X9500 menu screen looks like a correct calibrated almost 18% grey menu, I don't know how else to say that. I did calibrate both grey-scales on the projectors, there still seems to be a slight colour difference on screen however despite very quick cal, the menu doesn't seem to be affected by calibration at all, so that ugly red bias grey menu seems there to stay...

HDMI SYNC TIMES:

When Low Latency mode is on, my projector was syncing in 11.8 seconds for a 4k desktop image to appear, and 16.8 seconds when Low Latency mode is off. Thats also a repeatable 5 seconds quicker than the 9500 was generally. All modes seem to be between 2-3 seconds quicker syncing vs the 9500 when low latency mode is off.


LOW LATENCY MODE: This seems like it needs to be left ON at all times, at least on my unit, its sharper with it, there is some effed up blur ghosting artefact with Low Latency off, yes you read that right, Low Latency needs to be on for sharpest image. Its totally odd but the pics don't lie.

 

Perhaps my unit is misbehaving? It did come at default switched to On OOTB. EDIT - This has actually be corroborated by other owners, this may be a bug, but for best quality Low Latency must be off, oddly, cycling CMD on then off again removed the ghosting... but how long does that stick for? Perhaps on next power up the ghosting will be back, best to leave it ON.

ESHIFT 5 DOES NOT HAVE LESS MOSQUITO NOISE THAN ESHIFT 4. It just doesn't. The fine buzzing noise with your face to the screen is identical on both models. Sorry to see this, it was one of the things I was hoping to see improved, for a calmer image, but no.


Windows Desktop at 4k/ Still not native on either machine but no doubt the 9900 is getting closer to where it should be.

Now for this, lets look at Eshift 5 vs 4. At first your eyes may be drawn to the vertical lines being far sharper with actual gaps between then on eshift 4 and you would be right, but look at the letters and words... eshift 5 kills it with high density 4k text. But it seems to give up something all the same while doing it... which is a lesser evil? I really don't know, I am truly torn here...

Thanks Javs

 

Wonder if they kept the good stuff for the LTD20 and the X9900 is saddled with the shittier components that didn't make the grade. 

 

I think I will keep my X9500 for a bit longer then. 

 

Any chance you will get the Sony 760?

I'd say this is a dud unit in the first batch. Not acceptable but does happen.

 

Ironically my 7900 is stellar and I've still got my 7500 (which is just in getting the firmware updated) as I've sold it.

Edit, my 7500 I'd also like to say is superb! I wasn't implying my 7900 was some enormous stepup from my 7500, it's not possible.

 

I guess the problem is, you haven't gone back to JVC to see what's going on, instead just run with your review with what could well be, likely be, a faulty unit. Wouldn't you give them the benefit of the doubt first before posting this all over the forums?

They made 20 LTD units, that's it.

I'm telling it like it is Rich, like it or not mate. This is my experience, when I get a new one I will post an equally in depth look at that one and compare them.

 

If the next unit I get is the same I will report the same, I have faith that eventually it will be resolved, but many people were waiting on my thoughts, so I share them, good or bad...

 

Dud units should not be buried, they should be discussed as much as the good ones.

 

Besides, the lens in the centre is just as sharp as my 9500, I have said that, as such in depth Eshift analysis can still be done in the centre of the screen and carry plenty of relevance.

 

Does anybody disagree with that?

For "hand-picked optics" the chromatic aberration on the right side of the X9900 is dreadful - I'd hate to see the lenses flicked over to X7900 models that day...

 

I do wonder if one or more of the lens elements has separated on one edge - perhaps in transport, so giving JVC the benefit of the doubt, maybe not something visible during production.
