VS used some very high dollar gear to get the base ADC calibration done, and it gives you the baseline from which to make adjustments for a full CMS calibration. You also can't rerun the ADC calibration without the specific pattern that VS used, so do not delete the data, whatever you do!

I don't know that actual brightness increased any, according to my measurements, but everything looks brighter, because contrast is definitely improved. The same scenes that you're used to viewing show better blacks, the same great whites, and more detail in between. I may have gone a bit dimmer with your whites to avoid the horizontal banding on your unit, which may also be causing an even more notable difference. Either way, I'm glad you're enjoying the new settings. Does this mean you're not going to take delivery of the RS45? I have no doubts that the RS45 is an improvement on the Pro8100. It's just a question of, is it worth the cost? For me, at this point, I don't think it would be worth it, but I'd still love to get my hands on one to put through the paces!

After your new settings my Pro8100 is better than ever. I did few more tweaks and the colors are more accurate, brighter, sharper, and very film-like. The blacks are still gray in dark scenes but overall as a whole I am quite satisfied. I felt almost like having an upgrade or a new projector lol . I saw the X3 at Magnolia Design center (Perimeter) and didn't have the itch to upgrade. They should have the X30/X90 soon and Evolution Home theater (Buckhead) should have the X30 soon as well.
About my earlier comments about seeing more artifacts, EE, and banding, I found the Edge Enhancement was set to 5 . Setting back to zero and all is nice again. Come over and see my Pro8100 again

Has he checked getting a bulb w/o the housing? I did that for my Sony TV recently. Saved a few bucks and it was an easy change-out. Came w/ good instructions in original English.

Anything you change using the regular menus can be switched back, so there's no worries about fine tuning the calibration settings. However, I would warn that if you don't have a basic understanding of what each of the settings does, you can do more harm than good.

While no two units are alike, what I've found is that most people will not be able to spot minor variations in color. I can to a certain degree, but even after performing more than 50 calibrations of multiple display types, I wouldn't trust my eyes alone for accuracy. I've tried to do it, and gone back and measured, and am typically only within 10-15% of ideal. If you're truly want accuracy, you'll want to either buy a colorimeter and calibrate yourself or pay someone to do it for you. However, if "close enough" satisfies you, and you're not worried what the industry defines as "accurate," then there's nothing wrong with fine tuning another user's settings to your likes.

This whole exploding lamp thing .. ?? I mean, I know premature failure is likely more possible .. and from what I've gathered, the non-VS lamps sometimes get a review that says they seem a bit dimmer .. but exploding is way to strong a term IMO ..

BTW, Welcome Home and Merry Christmas Brother.

I've found some settings earlier in this thread that I'll play around with, but I was hoping for a little clarification on exactly what they do, instead of sitting there fiddling with them to see what happens.

First under colour temp there are offset and gain settings for each R, G and B. What's the difference between offset and gain?

Then under PCS, there's the "3D Colour Management". Each colour has adjustments for hue and colour. Again I'm a little confused as to how exactly these affect the display.

If I know what impact these have on the colour then it might be easier to figure this out.


Also, the "Cust1" and "Cust2" buttons on the remote - do they only load the colour temp settings saved to "Memory 1" and "Memory 2" or do they load all the PCS colour settings too?

What I'm trying to do is strike a balance between getting the vibrant, vivid colours for animated movies, and the more natural "film like" colours for more cinematic films.

If the Cust1 and Cust2 buttons load all settings and not just colour temp settings, then perhaps I can create two settings in the projector - one for animated and other for film?

Or am I going about this all wrong?

Next time I'll just resist the urge to fiddle

Thanks!
