Official JVC DLA-RS46 / DLA-X35 owners thread - Page 4

Thanks for posting this. Even though I don't plan on using the JVC for gaming, prefer it on my 30" HP ZR30W. I can't wait to try and see how FSX feels on a 120" screen. Should be epic!

Just running my first calibration on my X35. I'm using Chromapure autocal with my Lumagen. I've got a good greyscale straight away and even gained some brightness over my initial quick and dirty settings due to a brighter colour temperature (the default 6500K was a little too red) and I've decided to clip at 245 rather than show 255 (I used to clip at 235 with my HD350 so even that is an improvement). I went from 92 Lux peak white to just over 100 lux on my 1.5 gain screen. This is at minimum zoom and aperture at -15 so I'm enjoying the maximum contrast and still getting around 14fL (100 Lux x 0.929 x 1.5).

I'll post some results later to show the initial as found calibration and then the autocal results. I've done the gamut using both standard and wide so I can compare which gives the best results along with my Lumagen.

I have to agree. Going from 21db to 31db is not a small but a major jump in audible noise.
Others have said low lamp in the 45 and 46 were very similar. The big move was the higher noise in high lamp on the 46 compared to the 45.

Just a few results to show how the colour gamuts measure up at 75%. These are with the CMS in my Lumagen set to 'Off'. I hadn't realised that changing the colour space setting effects the greyscale, so my second autocal was a waste of time as I didn't redo the greyscale (colour space set to Standard) when I changed the colour space to Wide for the second attempt at CMS. Anyway, as the lamp will drift so quickly I'll get chance to run a full autocal in Wide another time.

This also means that only the standard colour space result below had the white set correctly (see the dE vaules), though the 'off' setting is still only 0.7dE for white so plenty good enough. I'll recheck the wide readings another time and repost them.

The Lan Port was used for firmware upgrades in the past. I think they now have a hidden usb port on the new models.

Came home to a pleasant surprise. It wasn't scheduled to be delivered until tomorrow, but UPS came a day early.

Hey Dragon Rebond About my noise measurement, I totally agree the X35 is very quiet in low mode lampe mode but with my sound meter and in my environnement, I'm not able to get a measure under 30DB so 31DB is a very good value.

Dragon-Are you projecting on a 16:9 or 2.35:1 screen? I'm guessing 16:9 since your lens is above the top of screen. I'll be using a 2.35:1 screen and my understanding is that I need to have the center of the lens no higher than the top of the screen in order for the lens memory to keep both 16:9 and 2.35 images on the screen. Is that correct?

80 ms lag
JVC is hopeless from a gamer point of view...

^ go the 2 projector setup route, works well for me.

I wonder if there is some sort of panel or hardware limitation preventing them from improving this since people have been asking for improvement here since the RS1 and no progress has been made. I would think a gaming mode which turns off all processing, etc.....could be incorporated to get some improvement, but maybe not?

I have a 2.35:1 screen without an anamorphic lens. I'll be using the lens memory feature to go between 2.35 and 16:9. 2.35 images will fill the screen and 16:9 will be zoomed down with vertical black bars. I was under the impression that even with lens memory, I wouldn't be able to do this with consistent results if the lens was above the top of the screen. Are vertical lens shift settings saved as part of the lens memory feature, in addition to zoom settings?

Your guess is as good as mine. I doubt that these adjustments would help, but dont know for sure.

Depending on what other processing (if any) you are going to do then the choice of colour space might be impacted: Wide might be a better option for those with Lumagen or DVDO outboard CMS, but without external CMS I'd suggest that Standard seems to be pretty good judging from my measurements last night prior to my calibration.

I've left my sharpness (and detail) at zero as I did with my HD350 as anything above zero starts to effect the chromaplate burst pattern causing ringing or other effects. I use my Darbee to help provide the effect of sharpness anyway. I know some like to crank up the setting, but it only seems to add ringing (in the form of a white line round dark objects and visa versa) and on my older HD350 I reckon it caused a kind of micro judder as well.

I think he was asking in reference to lag and if those type of changes could improve things in that area.

Oh I see. I thought you meant more generally, I'd overlooked the lag part as it's off my radar.

Highly recommend trying the Darbee as it saved me buying the X55 just for the Eshift (I already have the CMS covered by Lumagen anyway). Probably find that even on 10 & 10 there is some ringing, but likely only noticeable on test patterns, so if you prefer it, then why not?

I've tried toggling all the settings I could find, it's still ~80ms.
