Results:
- E-shift disabled, the JVC lagged the internal laptop display by about 7 frames (~115-120ms)
- E-shift enabled, about 8 frames (~133-136ms)
That is inline with the TrustedReview.com reviewer's result of 130 ms. 140 ms with E-shift enabled. (The laptop's own screen likely causes the 10 ms additional delay you measured. Or Marantz, if it does video processing.)

I project onto a 2.39:1 screen using my 4910 without an anamorphic lens (except that my screen is "only" 46" high). My projector lens center is about 5 inches above the top of the 16x9 image.

No. The height of the 16:9 image is 50" (height of 2.35 screen) so lens can only be 15" above this. The 16:9 image height is the limiting factor here.

I currently have an Epson 8100 which is quite bright with a Grey React 1.0 gain screen - it used be said that a JVC wasn't a good match with the Draper screen due to a lesser light output - I assume this is still the case?

Also, as my room is a normal living room, with light walls, I assume the better blacks of the JVC would be of limited benefit?

The screen will be 130" diagonal, and movies will be watched with all lights out, virtually no daytime viewing, if a big game, curtains will be closed.

Display : JVC X500 Projector | 130" ReAct 2.1 2.35:1 Screen | Panasonic 65VT30 |
Sources : Oppo 103 D Multizone | Apple TV3 | HTPC | Sky HD | Sonos Connect | Synology 24Tb |
Audio : Anthem MRX 510 | KEF R700 | KEF R600c | KEF E301 Sides & Rears | Paradigm Sub 1 |

I have a white 115in 1.0 gain screen in a black environment and it is bright enough for my taste, but from what you describe it may not have enough light output. I will tell you that it is an absolute stunning image and being able to get the most out of the contrast of the X500 goes along way in making that stunning image. I could be totally wrong, it may be enough light. Maybe someone else here has a similar setup as you.

I would not choose a projector like the X500 for your environment. Lights on during movies will be a lot of wasted money. If you are going to spend that type of money, why not get a better screen and a cheaper projector that's bright? Like a DLP, Epson?

Misread your previous message but the JVC should work in your environment

He also stated he has light colored walls and a 130in screen that is Gray. So it may actually struggle, may not, but the X500 is not a light cannon. I have a smaller and more reflective screen in a completely black environment and it could be brighter at times. So I would air with caution. A sony or an Epson may be a better fit. Every review or write up I read states the JVC performs best in a cave. He could also go with the step down model and get a higher gain screen. I think it is important to point out possible issues when giving advice on an expensive PJ.

Every PJ performs best in a cave.

Light colored walls affects intra scene contrast (ansi), but so much fade to black scenes or very dark scenes---i.e, black level, where a JVC shines (sorry for the anti-pun), but the 'brightness' of the scene will be just as bright, if not brighter, with light colored walls.
A gray screen can potentially be beneficial in a reflective environment, contrast wise.

Of course it's important to point out possible issues, but it's also important to point out errors in facts, which is all I did originally.

What are people's brightness settings at to see bar 17 flashing during calibration and not crush blacks? I have to push brightness to +10 to barely notice the smallest amount of flashing of bar 17 and even if I push brightness up all the way I don't see it clearly flashing or bar 16 or below flashing at all. Is there another setting I should be altering or am I doing something wrong possibly? Contrast is at -4 and was calibrating natural picture mode. Have 123" firehawk g3 screen. There was no ambient light except for back 2/3rds of ceiling is white and tan walls. (Soon to be covered in black velvet and then I will be trying to learn how to do a full calibration with software and meter)

I asked this on another thread as well but does anyone know if a used JVC RS57 with 3 hours on it is worth $600 more than a new X500 with spare lamp, 1 pair of 3d glasses and 3d emitter?

If you are in to 3D then i would say the X500 is the better deal. Even if you are not into 3D I have to say the X500 is the better deal. You can easily sell the 3d glasses and the emitter (the lamp is you choose to as well). Overall the JVC RS57 is more than $600 if you look at all the other goodies that you get with the X500.

ok thanks. So the x500 has an advantage over RS57.

So the RS57 isn't the X700 then?

Oops, my mistake, when I saw "used" I read I assumed it was an older generation model.

I'd still go with the 500, unless you have a small screen and can take advantage of the dual iris to get more CR.

No, the X35 / RS46 stayed the same from last year. The X500 / RS49(10) is a new model.

I'm almost certain the settings are lost after a firmware update and you will need to redo the calibration, but I don't have a current model to tell you for sure. Someone here should confirm, but just wanted to get you a tenative answer in the meantime.

Hi there mate,

 

As I remember after my upgrade, memory lens remained untouched and color profiles as well. If you worrying about that you should be able to export settings into HDD, via Ethernet Cable connected to PC, you can then import settings back, read in manual.

thanks guys - appreciate the info.

By the way - I was surprised by the artefacts that CMD introduces into some HD material (even when set to 'LOW'). On Oblivion I had these terrible vertical bands that appeared on shots with any white/grey backgrounds - absolutely unwatchable.

Once I turned it off, visual bliss ensued! The X500 is one helluva piece of kit.

I did not see that while watching Oblivion with the CMD on high, low seems to introduce issues but for me high runs nice.
